Answer:
Step-by-step explanation:
Put the values of x to the equation y = 2x + 2 and calculate the value of y:
x = 2
y = 2 · 2 + 2 = 4 + 2 = 6
x = 5
y = 2 · 5 + 2 = 10 + 2 = 12
x = 6
y = 2 · 6 + 2 = 12 + 2 = 14
x = 8
y = 2 · 8 + 2 = 16 + 2 = 18
Answer:
c
Step-by-step explanation:
Answer:
True
Step-by-step explanation:
a x ( b + c ) = a x b + a x c Substitute
-5 x ( 11/8 + c ) = -5 x 11/8 + -5 x c
-5 ( c + 11/8) = - 5c - 55/8
- 5c - 55/8 = - 5c - 55/8
True
Answer:
no not all
Step-by-step explanation:
<span>50-8t<90
50-90<8t
-40<8t
8t>-40
t>-5
Solutions should go to the right.
Mary probably was solving it as following
</span>50-8t<90
<span>-8t<90-50
-8t<40 (here, when she divided both sides by -8, she had to change sign < to the sign >)
But she did not change the sign, and got
t<-5
