Answer:

Hello. The answer is A.

Step-by-step explanation:

The number before x shows the slope.

The other number shows the y intercept.

<h3>It is important that the number before y should be one and the equation should be like this:</h3>

$y = mx + h$

Here h is intercept and m is slope.

I hope you understand.

Answer:

f^-1(x) = (x +4)/3

Step-by-step explanation:

The inverse function is found by swapping x and y, then solving for y.

y = 3x -4 . . . . . function y = f(x)

x = 3y -4 . . . . . inverse relation

x +4 = 3y . . . . add 4

(x +4)/3 = y . . . divide by 3. This is the inverse function

f^-1(x) = (x +4)/3

Ema ate 6 slices of pizza. She ate 3/4 of a entire pizza. How many slices of pizza were there in all?

Taya2010 [7]

Divide 6 by $\frac{3}{4}$

$\frac{6}{1}$ ÷ $\frac{3}{4}$

Change $\frac{3}{4}$ to a reciprocal

$\frac{6}{1}$ × $\frac{4}{3}$ = $\frac{24}{3}$

Simplify and your answer is 8

Suppose j varies jointly with g and v, and j=2 when g=4 and v=3. <br> Find j when g=8 and v=9.

vladimir2022 [97]

Answer:

$j=12$

Step-by-step explanation:

we know that

In a join variation, If j varies jointly with respect to g and v, the equation will be of the form $j = kgv$

where k is a constant

step 1

Find the value of k

we have

j=2,g=4,v=3

substitute and solve for k

$2 = k(4)(3)$

$2 = 12k$

$k=\frac{1}{6}$

The equation is equal to

$j=\frac{1}{6}gv$

step 2

Find the value of j when g=8,v=9

substitute the values in the equation and solve for j

$j=\frac{1}{6}(8)(9)$

$j=12$

How would u factorise these?!?

Tcecarenko [31]

You can pull out a greatest common factor (GCF).
1. GCF: x
2. GCF: p
3. GCF: 8

Solve the equation 12+ 0.35×=20.05

lbvjy [14]

12 + 0.35X = 20.05
12 + 0.35X - 12 = 20.05 - 12
0.35X = 8.05
0.35X/0.35 = 8.05/0.35
X = 23
Hope this helps!!
