The answer to this question is 17.5. Because i divided 20 by 8 and got 2.5 and times it by 7.
17.5
Answer:
x- intercept = 2
Step-by-step explanation:
The x- intercept is the value of x on the x- axis where the line crosses.
The line crosses the x- axis at A (2, 0 ) , then
x- intercept = 2
5(2x - 8) + 15 = -15
-15 -15 subtract 15 from each side
5(2x - 8) = -30
÷5 ÷5 divide both sides by 5
2x - 8 = -6
+8 +8 add 8 to each side
2x=2
÷2 ÷2 divide both sides by 3
x = 1
Checking:
5(2(1)-8) + 15 = -15
5(-6) + 15 = -15
-30 + 15 = -15
-15 = -15 Correct! x=1
Step-by-step explanation:
The equation of a line in point slope form when given a point and slope can be found by using the formula
![y - y_1 = m(x - x_1)](https://tex.z-dn.net/?f=y%20-%20%20y_1%20%3D%20m%28x%20-%20%20x_1%29)
where
m is the slope
( x1 , y1) is the point
From the question the point is ( - 4 , 3) and slope - ⅔ is
The equation of the line is
<h2>
![y - 3 = - \frac{2}{3} (x + 4)](https://tex.z-dn.net/?f=y%20%20-%203%20%3D%20%20-%20%20%5Cfrac%7B2%7D%7B3%7D%20%28x%20%2B%204%29)
</h2>
