Answer:
I think the answer is letter C.Find an equation of a line perpendicular to the given line and contains the given point. Write the equation in slope-intercept form.
y = ?
Answer:
y = -1/5 x -2
Step-by-step explanation:
Given line y = 5x - 1
as in slope intercept form m = 5
point (5, -3)
for two lines to be perpendicular product of slopes must be -1\
so for new line slope is
m1 * m2 = -1
5 * m2 = -1
m2 = -1/5
line equation is y - (-3) = -1/5 (x - 5)
y + 3 = -1/5 x + 1
y = -1/5 x + 1 - 3
y = -1/5 x -2
Answer:
Step-by-step explanation:
Slope of the ⊥ line is ( - [tex]\frac{1}{5}[/tex] )
y - ( - 3 ) = - [tex]\frac{1}{5}[/tex] ( x - 5 )
y + 3 = - [tex]\frac{1}{5}[/tex] x + 1
y = - [tex]\frac{1}{5}[/tex] x - 2

(2x+1)(x+5)
6x-4xy
16x^2-25
Step-by-step explanation:
i believe what you need help on is simplifying the equations. so let's start with the first one.
====================================================================
(2x+1)(x+5) original problem
(2x)(x)+(2x)(5)+(1)(x)+(1)(5) we can break this down into smaller pieces so we know what we're dealing with in this equation.
2x2+10x+x+5 if we break this down a little more and add some bracket numbers, this is what we get.
2x2+11x+5 this is the most simplified equation.
====================================================================
6x−4xy original problem.
unlike the last problem, we can easily just... 6x + (−4xy).
−4xy+6x this is the most simplified equation.
====================================================================
ok, the last one. phew!
unfortunately, 16x^2-25 is actually the simplest it can get. so, let's try factoring.
if we factored, we would get...
(4x+5)(4x−5)
===================================================================

Mika bought 1 vintage movie poster, 1 rock poster, and 2 rap posters. She had a coupon for half off her entire purchase.
Part 1: Select the numerical expression that shows how much Mika paid for the posters.
A) [28.50 + 29.75 + 2(19.50)] ÷ 2
B) 28.50 + 29.75 + 19.50 + 19.50 ÷ 2
C) [28.50 + 29.75 + 19.50 + 19.50] ÷ 1/2
D) [28.50 + 29.75 + 2(19.50)] ÷ 1/2

Answer:
3/2 and 3/4
Step-by-step explanation:
First, we need to know: what is a decimal that terminates?
A decimal that terminates is a decimal that has an end
For ex: 1/4 = 0.25
The decimal won't go on and on, it ends with only a few digits
Here's an example of one that doesn't terminate:
1/3 = 0.3333333333333333333333333333333333 . . . . . and so on
With this knowledge, we can look at the fractions in your problem: 3/2, 2/3, 3/4, and 5/7
To find the decimals, divide the numerator by the denominator, you get:
1.5, 0.66666666 . . ., 0.75, and 0.71428571428 . .,
We can see that the first and third don't run on, while the second and last do.
Therefore, your answer would be 3/2 and 3/4
The length and width of a square is 9.5 inches (for both) what is the area and perimeter?
Answer:
90.25, 38
Step-by-step explanation:
The area is the two sides multiplied against each other, so 9.5*9.5
Since it's a square all of the sides are 9.5 inches, so just multiply 9.5 times 4 for the perimeter
Find the equation of a line containing the given points. Write the equation in slope-intercept form.

Step-by-step explanation:
Answer: D Or 10
Step-by-step explanation: Because If you subtract 50 by 32 you will get 18 and then you get 5/9(18) and then you can cross simplify which gets you 5x2 which is 10.

Is 7.6 greater than, equal to, or less than 7.60
Answer:
Equal to
Step-by-step explanation:
It is found that 7.6 repeating is equal to 7.60
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The "=" sign and terms on both sides must always be present when writing an equation.
We are given the number 7.6 so we have to find whether the number is greater than, equal to, or less than 7.60
Therefore, we can see that 7.6 = 7.60
So they are equal to each other.

in kick boxing, it is found that the force needed to break a board varies inversely with the length of the board. If it takes 5 lbs. of pressure to break a board 2 feet long, how many pounds of pressure will it take to break a board that is 8 feet long
Answer:
20
Step-by-step explanation:
Since we know that it takes 5lbs. to break a 2-foot longboard, we first want to figure out how many pounds it takes to break a 1foot board.
5/2=2.5
It takes 2.5 lbs to break a 1-foot board.
2.5x8=20
It would take 20lbs to break an 8-foot longboard.
Hope this helps :)

Answer:
13.5
Step-by-step explanation:
Answer:
3% of 450$ is 13.50$ so if it was just split between the salesperson and the store she would have made 13.50 and the store would have made 436.50

A survey of all beings on planet Frank found that 25% preferred kent juice to all other juices. If 10 beings preferred kent juice, how many beings were surveyed altogether?
Answer:
40
Step-by-step explanation:
25% is the same as [tex]\frac{1}{4}[/tex], so we can use the following equation:
[tex]\frac{1}{4}x = 10[/tex]
From there, multiply both sides by four to get [tex]x=40[/tex].
This means that 25% of [tex]40[/tex] is [tex]10[/tex].

the serving size for a toddlers daily vitamin c is 3/4 cup of orange juice. if there are 2 1/4
cups of orange juice how many servings of vitamin c are there for a toddler
Answer:
Three servings
To find the number of servings we need to determine how many sets of 3/4 there are in 2 1/4 .
2 1/4 divided by 2 (4) + 1 = 1/4= 4/1 = 4 which will equal 9/4
9/4 divided by 3/4= 9/4 x 4/3 =9/3= 3 servings

Find what the x is.
45= 5/7x
Answer:
x = 63
Step-by-step explanation:
Step 1: Multiply both sides by 7/5.
[tex]45 *\frac{7}{5}=\frac{5}{7}x*\frac{7}{5}[/tex] [tex]63 = x[/tex]Step 2: Check if solution is correct.
[tex]45 = \frac{5}{7}(63)[/tex] [tex]45 = 5 * 9[/tex] [tex]45 = 45[/tex]Therefore, x = 63.
x = 63
Step-by-step explanation:45 = 5/7x
=> 9 = x/7
=> x = 63.
