Answer:
k(-1) = 7.
Step-by-step explanation:
k(-1) is the value of the function k when x = -1.
You read this off the graph.
Find the value of the point on the graph which corresponds to x = -1. From x = -1 on the horizontal axis move straight up until you meet the graph of k. Now look horizontally to the right and read off the value on the vertical
y-axis
You'll find it is 7.
Hey there,
148 = 2x + 6(x + 10)
148 = 2x + 6x + 60
148 = 8x + 60
-60 - 60
88 = 8x
/8 /8
11 = x
6x + 4(-x - 14) = -42
6x -4x - 56 = -42
2x - 56 = -42
+ 56 + 56
2x = 14
/2 /2
x = 7
-101 = 7x -4(-3x - 8)
-101 = 7x + 12x + 32
-101 = 19x + 32
- 32 - 32
-133 = 19x
/19 /19
-7 = x
Hope I helped :)

Answer:
cos 29 = x / 11
11 * cos 29 = x
x = 11 * 0.87462
x = 9.62082
Step-by-step explanation:
Y= 2x + 2 , the y intercept is 2, the graph was provide this point for u already . E Then , I just found the slope by using the formula that I had learned from textbook , which is M= y2 - Y1 divided by X2-X1 .
y = a(x + 16)(x + 2)
72 = a(-18 + 16)(-18 + 2)
72 = a(-2)(-16)
72 = a(32)


Answer: y =
(x + 16)(x + 2)
