Solve for in x in
4+3 (2x-4)=28
Answer: x=6
Step-by-step explanation:
Let's solve your equation step-by-step.
4+3(2x−4)=28
Step 1: Simplify both sides of the equation.
4+3(2x−4)=28
4+(3)(2x)+(3)(−4)=28(Distribute)
4+6x+−12=28
(6x)+(4+−12)=28(Combine Like Terms)
6x+−8=28
6x−8=28
Step 2: Add 8 to both sides.
6x−8+8=28+8
6x=36
Step 3: Divide both sides by 6.
6x

Answer:
[tex]x=6[/tex]
Step-by-step explanation:
[tex]4+3 (2x-4)=28[/tex]
Distribute 3 to the parenthesis:
[tex]4+6x-12=28[/tex]
Add 12 to both sides:
[tex]4+6x-12=28[/tex]
+12 +12
[tex]4+6x=40[/tex]
Subtract 4 from both sides:
[tex]4+6x=40[/tex]
-4 -4
[tex]6x=36[/tex]
Divide both sides by 6
[tex]6x=36[/tex]
/6 /6
[tex]x=6[/tex]

The function h defined by h(t)=(49 + 4.9t)(10 - t) models the height, in meters, of an object t seconds after it is dropped from a helicopter.
From what height is the object dropped? Explain how you know.
Answer:
Step-by-step explanation:
Let's FOIL this out and get it into standard quadratic format:
[tex]h(t)=-4.9t^2+490[/tex]. The lack of a linear term in the middle means therewas no upwards velocity, consistent with the object being dropped straight down as opposed to thrown up in the air tand then falling in a parabolic path. The -4.9t² represents the acceleration due to gravity, and the 490 represents the height from which the object was dropped. The constant in a quadratic that is modeling parabolic motion always represents the height from which the object was dropped (or launched). That's how you know.
The requried initial height of the object is 490 meters.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
The object is dropped from a height of 49 meters.
We know this because the initial height is given by the first term of the expression in the parentheses, which is 49. When the object is dropped from the helicopter, t is equal to zero. Substituting t=0 into the equation for h gives:
h(0) = (49 + 4.9(0))(10 - 0) = 49(10) = 490
Therefore, the initial height of the object is 490 meters.

Find the center and the radius of the circle with the equation:
x2 - 2x + y2 + 4y + 1 = 0
Complete the square:
x ^2 - 2x + y ^2 + 4y + 1 = 0
(x - 1)^2 + (y + 2)^2 + 1 = 1 + 4
(x - 1)^2 + (y + 2)^2 = 4 = 2^2
Hence the center is (1, -2) and the radius is 2. (D)

Answer:
c = 60°

In a company, 55% of the workers are men. if 1,305 people work for the company who aren't men, how many workers are there in all? Use pencil and paper.
Answer:
If in a company, 55% of workers are men, then,
100%-55%=45% in the company aren't men.
If x be the total number of workers in the company, then
45% of x=those who aren't men
45/100*x=1305
x=2900
Therefore, the total number of workers is 2900.

Type the correct answer in each box. The reflection of point S across the y-axis is point . The reflection of point Q across the x-axis and the y-axis is point , whose coordinates are (, ).
Answer:
[tex]S' = (-5,-5)[/tex]
[tex]Q"=(-5,-5)[/tex]
Step-by-step explanation:
Given
[tex]S = (5,-5)[/tex]
[tex]Q= (5,5)[/tex]
Solving (a): Reflect S across y-axis
The rule to reflect across y-axis is:
[tex](x,y) \to (-x,y)[/tex]
So, we have:
[tex]S(5,-5) \to S'(-5,-5)[/tex]
Hence:
[tex]S' = (-5,-5)[/tex]
Solving (b): Reflect Q across x and y-axis
The rule to reflect across x-axis is:
[tex](x,y) \to (x,-y)[/tex]
So:
[tex]Q(5,5) \to Q'(5,-5)[/tex]
The rule to reflect across y-axis is:
[tex](x,y) \to (-x,y)[/tex]
So:
[tex]Q'(5,-5) \to Q"(-5,-5)[/tex]
Hence:
[tex]Q"=(-5,-5)[/tex]

Step-by-step explanation:
there are 6 boxes each weight 720g that mickey mouse need to carry to goofy house mickey is only strong enough to carry 4 kg at one time. can mickey carry all the boxes on one trip? show work to explain how you know
Step-by-step explanation:
Mickey can't carry all the boxes on one trip because each box contain 720 which means that one box is 720g so if u multiple 6 (720) = 4320g which is 4.32kg so in order for Mickey to carry all his boxes on one trip then he have to increase his maximum level1.

The product of two consecutive positive odd integers is 38 less than the square of the greater integer. Find the integers.
Answer:
Let the first integer be 'n.' Then n(n+2)+38=(n+2)^2. Solve using the quadratic equation: n=17. The two odd integers are 17 and 19.
Step-by-step explanation:
The integers are -39 and -38.
What are natural numbers, rational numbers, integers and irrational numbers?Natural numbers are: 1, 2, 3, ....
Integer numbers are: ...., -2, -1, 0, 1, 2, ... (so it includes positive and negative natural number, and 0 )
Rational numbers are numbers which can be written in the form of [tex]\dfrac{a}{b}[/tex] where a and b are integers. Example: 1/2, 3.5 (which is writable as 7/5) etc.
Irrational numbers are those real numbers which are not rational numbers.
Know that all natural numbers are integers, all integers are rational numbers. That means, natural numbers are not irrational.
Given;
The product of two consecutive positive odd integers is 38 less than the square of the greater integer
Now, let the numbers be x and x+
So, the equations will be
x(x+1)-38=(x+1)^2
x^2+x-38=x^2+1+2x
x=-39
x+1=-38
Therefore, the integer numbers will be -39 and -38.

what is the solution set of (-1/3,4)
Answer:
if the solutsion are r1,r2 then the factored form is
y=a(x-r1)(x-r2) where a is a constant
so
r1=-1/3
r2=4
y=a(x-(-1/3))(x-4)
y=a(x+1/3)(x-4)
so it will be

Which polynomial is equivalent to (18n^2 - 9n +1) divided by (3n - 1)? Assume the divisor is not equal to zero.
Answer:
6n-1
Step-by-step explanation:
The Equivalent polynomial is 6n-1.
What is polynomial?An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.
We have,
To divide (18n² - 9n+ 1) by (3n-1).

Answer:
-74 10/5
Step-by-step explanation:
first you will write the decimal number in fraction form which will be,
-74.5 = -745/10
now, on diving we will get,
74 as quotient and 5 as remainder, 10 as divisor.
now mixed fraction is, quotient divisor/remainder

The Angle of depression from the top of the flagpole to an object on the ground it's 33° if the object is 60 feet from the base of the cliff how tall is the flag pole
Answer:
The flag pole is 38.96 feet tall.
Step-by-step explanation:
The angle of depression from the top of the flagpole to an object on the ground is 33°.
The object is 60 feet from the base of the cliff.
We need to find the height of the flag pole.
Here, base, B = 60 feet
We know that,
[tex]\tan\theta=\dfrac{P}{B}[/tex]
Put all the values to find P.
[tex]P=B\times \tan\theta\\\\P=60\times \tan(33)\\\\P=38.96\ ft[/tex]
So, the flag pole is 38.96 feet tall.

Answer:
[tex] \frac{15 \sqrt{209} }{209} [/tex]
Step-by-step explanation:
Objective: Understand and work with trig identies.
Recall multiple trig identies and manipulate them to get from cosecant to secant.
Given
[tex] \csc(a) = \frac{60}{16} [/tex]
Apply reciprocal identity csc a = 1/sin a.
[tex] \sin(a) = \frac{16}{60} [/tex]
Apply pythagorean identity to find cos a.
[tex]( \frac{16}{60}) {}^{2} + \cos(x) {}^{2} = 1[/tex]
[tex] \frac{256}{3600} + \cos(x) {}^{2} = 1[/tex]
[tex] \cos(x) {}^{2} = \frac{3600}{3600} - \frac{256}{3600} [/tex]
We can simplify both expression
[tex] \cos(x) {}^{2} = \frac{225}{225} - \frac{16}{225} [/tex]
[tex] \cos(x) = \frac{ \sqrt{209} }{15} [/tex]
Cosine is positve on quadrant 1 so that cos(a)
Apply reciprocal identity sec a= 1/ cos a.
The answer is
[tex] \sec(a) = \frac{15}{ \sqrt{209} } [/tex]
Rationalize the denominator.
[tex] \frac{15}{ \sqrt{209} } \times \frac{ \sqrt{209} }{ \sqrt{209} } = \frac{15 \sqrt{209} }{209} [/tex]

What is the answer to the below questions 1.Find the sum of 72−104+5and -32+ 4-10. 2.What should be added to 32+32+3 to get 3+3? 3.Subtract the sum of 12ab –10bc –18ac and 9ab +12bc + 14ac from the sum of ab + 2bc and 3bc –ac
Answer:
-65
-61
20ab - 3bc - 3ac
Step-by-step explanation:
1.) Find the sum of 72−104+5and -32+ 4-10.
72 - 104 + 5 = - 27
- 32 + 4 - 10 = - 38
Sum of (-27 and - 38) = - 27 + (-38) = - 65
2.) What should be added to 32+32+3 to get 3+3
32 + 32 + 3 = 67
3 + 3 = 6
67 + x = 6
x = 6 - 67
x = - 61
3.) Subtract the sum of 12ab –10bc –18ac and 9ab +12bc + 14ac from the sum of ab + 2bc and 3bc –ac
(12ab –10bc –18ac) + (9ab +12bc + 14ac)
12ab + 9ab - 10bc + 12bc - 18ac + 14ac
= 21ab + 2bc - 4ac
(ab + 2bc) + (3bc - ac)
ab + 2bc + 3bc - ac
ab + 5bc - ac
(21ab + 2bc - 4ac) - (ab + 5bc - ac)
21ab + 2bc - 4ac - ab - 5bc + ac
21ab - ab + 2bc - 5bc - 4ac + ac
20ab - 3bc - 3ac
