The total angle inside the U-shaped is 180 degree.
110 + (8x-10) = 180
8x-10 = 70
8x = 80
x = 10
Answer:
b
Step-by-step explanation:
There are four solid and dotted sections and eight sections in total so the probability is 4/8 or 1/2
Answer:
C
Step-by-step explanation:
The first one (0,7) tells you that when x isn't there, the amount of money is 7.
That means that the y intercept is 7.
When x = 1 the total is 15
Money saved = ax + 7
15 = a*1 + 7 Subtract 7
15-7 = a + 7-7
a = 8
The equation is f(x) = 8x + 7
Answer:
y=1x-8
Step-by-step explanation:
Lets do the same thing we did last time
-3=1(5)+?
-3=5+?
The y intercept is -8
CHECK:
-3=1(5)+-8
-3=5+-8
-3=-3
