Answer:
a = 14
Step-by-step explanation:
3a = a + 28 ➡ 2a = 28 ➡ a = 14
Answer:
Points on the inverse are
Step-by-step explanation:
When writing the inverse function of a set of points, you simply switch the coordinates:
We are given the points
Using our rule for function, our new points will be
From the list, the points we have for the graph of the inverse are
Answer:
- y = x - 6
- y = -x + 5
- y = x - 5
Step-by-step explanation:
<em>Slope - intercept formula: y = mx + b, where m- slope, b- y-intercept</em>
<u>1. Points are:</u>
<u>Slope is:</u>
- m = (y2 - y1)/(x2 - x1)
- m = (-2 - (-4))/(4 - 2) = 2/2 = 1
y-intercept is - 6 as per graph
<u>Then the formula is</u>
<u>2. Points are:</u>
<u>Slope is:</u>
- m = (1 - 5)/(4 - 0) = -4/4 = -1
y-intercept is 5 as per point
<u>Then the formula is</u>
<u>3. Points are:</u>
<u>Slope is</u>
- m = (3 - 1)/(-1 -(-3)) = 2/2 = 1
y-intercept is -5 as per graph
<u>Then the formula is</u>
I think its letter C 58.85
Answer:
y = -1 (x - 1)² + 4

im pretty sure thats right but if not sorry :(
