Answer:
Square root property
Step-by-step explanation:
The given equation is :
[tex]x^2+6=31[/tex]
We need to write the most appropriated technique to solve the above equation.
Subtracting both sides of the above equation by 6 such that,
[tex]x^2+6-6=31-6\\\\x^2=25[/tex]
Now taking square root on both sides we get :
[tex]x=\sqrt{25}[/tex]
The square root property is used here, such that the value of x is :
[tex]x=\pm 5[/tex]
Can I get an example of systems of equations that represent the solution of this situation below? Thank you! ^ ^
"1 taco and 1 burrito costs $11. 10 tacos and 5 burritos cost $80. How much is the cost of one burrito?" (x = the cost of a taco, and y = the cost of a burrito)
Answer:
1x+ 1y =11
10x + 5y = 80
x = the cost of a taco = $5
y = the cost of a burrito = $6
Step-by-step explanation:
x = the cost of a taco
y = the cost of a burrito
1x+ 1y =11
10x + 5y = 80
rearange 1st equation as y = 11 -x and plug in into the 2nd one for y:
10x + 5( 11-x) = 80 distribute left side
10x + 55 - 5x = 80 combine like terms
10x - 5x = 5x
5x + 55 = 80 subtract 55 from both sides
5x = 80 - 55
5x = 25 divide by 5
x = 5
plug in for y in 1st equation y = 11--x =11-5 = 6
If Marc ran 10 miles in 3 hours, how far can he run in 6 hours?
Answer: 20 miles
Step-by-step explanation: if he runs 10 miles in 3 hours then double the amount of 10 which is 20 because 3 multiplied by 2 equals 6
I need some help with this question, I got a different answer.
Answer:
The median is the middle number.
Step-by-step explanation:
You have to order the numbers from least to greatest, or greatest to least, and choose the number in the middle. Since there is an even number of values, you have to take the mean of the two middle numbers. I hope this helps.
The polynomial f(x) is written in factored form:
f(x) = (x - 3)(x + 8)(x - 11)
What are the zeros of the polynomial function?
O x = 3, x = 8, x = 11
O x = 3, x = -8, x = 11
OX=-3, x = 8, X = -11
x = -3, x = 3, x = -8, x = 8, x= -11, x = 11
Answer:
F(x)=(x-3)(x+8)(x-11)=0
(x-3)=0, (x+8)=0, (x-11)=0
X=3
X=-8
X=11
Which function represents f(x)=3^x ?
Answer:
The answer would be function 2.
Step-by-step explanation:

Suma inverselor a două numere raționale este , iar diferența inverselor numerelor este . Calculați suma și produsul numerelor.
Answer:
The sum of the inverses of two rational numbers is 5 by 6, and the difference of the inverses of the numbers is 1 by 6. Calculate the sum and product of numbers.
Sum = a + b = 5
Product = a ₓ b = 6
Step-by-step explanation:
[tex]\frac{1}{a} +\frac{1}{b} =\frac{5}{6}[/tex]
[tex]\frac{1}{a} -\frac{1}{b} =\frac{1}{6}[/tex]
Add both equations together
[tex]\frac{1}{a} +\frac{1}{a} +\frac{1}{b} -\frac{a}{b} =\frac{5}{6} +\frac{1}{6}[/tex]
2 / a = 6/6
2 / a = 1
a = 2
we replace in any relation a
1 / 2 + 1 / b = 5 / 6
3b + 6 = 5b
5b - 3b = 6
2b = 6
b = 3
Sum = a + b = 2 + 3 = 5
Product = a ₓ b = 2 ₓ 3 = 6
What is the area of the triangle?
Answer: 24
Step-by-step explanation:
Area = 1/2 x base x height
Answer:
24cm²
Step-by-step explanation:
So you do 8×4=48 (a square) then half it (triangle) which becomes 24cm²
Well, a simple way to do it is to do base × height then half it
Which expression is equivalent to the following complex fraction?
Answer:
Step-by-step explanaAnswer:
\frac{-2y+5x}{3x-2y}
Step-by-step explanation:
Given:
\frac{\frac{-2}{x}+\frac{5}{y}}{\frac{3}{y}-\frac{2}{x}}
To simplify this expression, first make the addition and the subtraction, to get:
\frac{\frac{-2y+5x}{xy}}{\frac{3x-2y}{xy}}=
Next, simplify the two denominators, to get:
\frac{-2y+5x}{3x-2y}tion:
So the right answer is of option B.

math question below
Answer: The package reaches the ground in
4.67 s
and hits the ground with a speed of
33.8 m/s
Answer:
3m/s or option 1
Step-by-step explanation:
Given,
Height(h)=90m
time(t)=30s
Speed(v)=?
Now,
Speed(v)=distance/time
v=height/time(Since,height here is the distance covered by the balloon)
v=90/30
v=3
Unit of speed is m/s
Therefore,v=3m/s

3/4
1/2
5/8??
Answer:
1/2
Step-by-step explanation:
There are exactly 6 shaded regions; for every shaded region, there is also an unshaded region -- making this value 6 as well.
There are 12 possible outcomes, and 6 events
To determine probability, we divide the number of events by the number of possible outcomes, like this:
[tex]6/12=1/2\\1/2=.50\\[/tex]
.50 = 50% or 1/2 chance.

The area of a parallelogram 420 square cm and the height is 35 cm. Find the corresponding base.
Answer:
12
Step-by-step explanation:
420/35
12
12*35=420
Answer:
The corresponding base is 12 cm.
Step-by-step explanation:
The area of a parallelogram is calculated with the formula of A=bh, where b is the base and h is the height.
You can apply the problem to the formula:
420=b(35)
To solve, work backwards.
Divide 35 to both sides.
420 divided by 35 is 12
b=12
Hope this helps!
3) Which of the equivalent expressions for P(x) reveals the profit when the price is
zero without changing the form of the expression?
a) P(x) = -3x2 + 432x - 1680
b) P(x) = -3(x - 4)(x - 140)
c) P(x) = -3(x - 72)2 + 13872
4) Find the profit when the price is zero.
Question:
Which of the equivalent expressions for P(x) reveals the profit when the price is
zero without changing the form of the expression? P(x) = -3x² + 432x - 1680
a) P(x) = -3(x - 4)(x - 140)
b) P(x) = -3(x - 72)² + 13872
Find the profit when the price is zero
Answer:
- P(x) = -3(x - 140)(x - 4).
- P(0) = -1680
Step-by-step explanation:
Given
P(x) = -3x² + 432x - 1680
Required
- Find equivalent of P(x)
- Find P(x) when x = 0
To find the equivalent of P(x), we simply factorize P(x) = -3x² + 432x - 1680.
This is done as follows
P(x) = -3x² + 432x - 1680
P(x) = -3x² + 12x + 420x - 1680
P(x) = -3x(x - 4) + 420(x - 4)
P(x) = (-3x + 420)(x - 4)
Further expand -3x + 420
P(x) = -3(x - 140)(x - 4).
Hence, the equivalent of
P(x) = -3x² + 432x - 1680
without changing its form is
P(x) = -3(x - 140)(x - 4).
When price is 0, then x = 0.
Substitute 0 for P(x) in P(x) = -3(x - 140)(x - 4).
P(0) = -3(0 - 140)(0 - 4).
P(0) = -3(-140)(-4)
P(0) = -1680
Hence, the profit when price is 0 is -1680
