Answer:
Step-by-step explanation:
4 3/4 divided by 3/4
= 19/4 ÷ 3/4
= 19/4 ÷ 4/3
= 19/3
= 6 1/3
(7^2)x = 1
x = 1/(7^2) = 7^(-2).
You obtain the value of x by dividing both sides by 7^2 and the inverse of 7^2 is 7^(-2).
Answer:
9
Step-by-step explanation:
The equation graphed from these points is y=3x+9, therefore the y-intercept is 9.
<u><em>Answer:</em></u>
slope = ![\frac{-7}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-7%7D%7B4%7D%20%20)
<u><em>Explanation:</em></u>
<u>The general form of the linear line is:</u>
y = mx + c
where:
m is the slope
c is the y-intercept
<u>The given equation is:</u>
7x + 4y = 20
<u>We will start by putting the equation in the general form:</u>
7x + 4y = 20
4y = -7x + 20
![\frac{4y}{4} = \frac{-7x}{4} + \frac{20}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4y%7D%7B4%7D%20%3D%20%5Cfrac%7B-7x%7D%7B4%7D%20%2B%20%5Cfrac%7B20%7D%7B4%7D%20%20)
y = ![\frac{-7}{4} x + 5](https://tex.z-dn.net/?f=%20%5Cfrac%7B-7%7D%7B4%7D%20x%20%2B%205%20)
<u>Now, comparing our equation with the general form, we would find that:</u>
m = slope = ![\frac{-7}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-7%7D%7B4%7D%20%20)
c = y-intercept = 5
Hope this helps :)
