Answer:
1. If x=5, 3*5=15, 15*15=225 + y (3) = 228.
2. If y=4, then 10*4 = 40, 4^2 is 16, so 40 + 16 is 56.
I might be wrong, but the first one you answered, x^2, x= 1/2, I think that is wrong. when something is squared, you don't go, "Oh, well since 1/2 equals 1, that's the answer." The way to figure out something like this is... 1/2 times 1/2, which is .25, or 1/4. Another example: 3^5 . The way to find this out is 3*3*3*3*3 = 243. But you don't go 3*5, because that answer would be 15, which is not correct.

Write your answers in simplest form.
Answers
Answer:
The slope is 5/4 and the y-intercept is 2.
Step-by-step explanation:
5x-4y=-8
4y=5x-(-8)
4y=5x+8
y=5/4x+8/4
y=5/4x+2
y=mx+b where m=slope and b=y-intercept.
Gabriel took a bath on Monday evening. He measured the water and found that he used 1,235l of water. On Tuesday, he took a shower and only used 478 litres of water. What was the difference in volumes? How much water did he used in total?
Answers
Answer:a)757liters
b)1, 713 litres
Step-by-step explanation:
Amount of water used on Monday =1,235l
Amount of water used on Tuesday =478liters
Difference in volumes for the two days
=1,235l -478l
=757liters.
Total amount of water used up in Total
1,235litres +478liters
=. 1, 713 litres.

A student earns an 80% on their science test. If she got 20 questions correct, how many total were on the test?
Answers
Answer:
25 questions
Step-by-step explanation:
20 questions = 80% If she got 80%, that means she got 20 questions correct.
5 questions = 20% Here, we simply just divide by 4 to give us 20%.
25 questions = 100% The total of the test would of course equal 100%, so we just multiply by 5 to give the total questions.

MP =8
Step-by-step explanation:
QR = 1/2 MP
76 -8x = 1/2 (89 - 9x) Multiply both sides by 2
152 - 16x = 89 - 9x Subtract 89 from both sides
152-89 - 16x = - 9x Add 16x to both sides.
63 - 16x +16x = 16x - 9x
63 =7x Divide by 7
x = 63/7
x = 9
MP = 89 - 9*9
MP = 8
how to count slope on linear equasions
Answers
Answer:Do rise over run, maybe watch a tutorial on it, pretty simple method
Answer:
there are only three simple steps (:
Step-by-step explanation:
1. identify the two points on the line
2. select one to be (x1, y,1) (rise over run) and the other to be (x2, y2)
3. use slope equation to calculate your slope (m=rise/run= y2-y2/x2-x1)
in the equation of a straight line (equation written y=mx+b) the slope is m and b is the y intercept. (where the line crosses the y axis) this is the slope intercept form)

Answers
Answer:-8
Step-by-step explanation:
The data represent a linear function because there is a common difference of -9.
What is a linear function?The term linear function refers to two distinct but related notions: In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.
Given, the table, we need to see whether the data in the table represent a linear function or an exponential function.
From the table, we have the following highlight :-
As the values of x increase by 1, the values of y decrease by 9
A decrement of 9, means -9
This means that, the common difference is -9.
Only a linear function can have a common difference.
Hence, the true statement is (b)

The graph of the invertible function f is shown on the grid below
What is the value of f^-1(6)
Answers
Given:
The graph of an invertible function [tex]f[/tex] is given.
To find:
The value of [tex]f^{-1}(-3)[/tex].
Solution:
We know that, if the graph of an invertible function [tex]f[/tex] passes through the point (a,b), then the inverse function [tex]f^{-1}[/tex] passes through the point (b,a).
From the given graph it is clear that the graph of the function [tex]f[/tex] passes through the points [tex](-5,-3)[/tex].
So, the inverse function [tex]f^{-1}[/tex] must be passes through the point [tex](-3,-5)[/tex].
Therefore, the value of inverse function is [tex]-5[/tex] at [tex]x=-3[/tex]. So, the value of [tex]f^{-1}(-3)[/tex] is [tex]-5[/tex].
