= 
So, + 
= 
169 - 9 = 160
is 12.65.
Hope it helps.
Answer:
x = -7
Step-by-step explanation:
f(x) = -2x + 9
f(x) = 23
therefore, f(x) =
-2x + 9 = 23
-2x = 23 - 9
-2x = 14
-x = 14 ÷ 2
-x = 7
x = -7
$4.5 per service x 8 = $36.00
$18.00 x 8 = $144 x 20% = $29.00
$65.00
Given that the linear relationship between height and age is given by:
y=64.93+0.63x
To get Joseph's height given that he was 22.5 months old we proceed a follows:
x=22.5
plugging our value in the formula we obtain:
y=64.93+0.63(22.5)
simplifying:
y=64.93+14.175
y=79.105 cm
