Answer:
36 degreees
Step-by-step explanation:
JKL = 9x + 18
54 = 9x + 18
36 = 9x
4 = x
6(4) + 12 = 36
Y = mx + b
4 = m(248) + b
6 = m(372) + b
subtract the two equations to get
-2 = m(-124) + 0
m = 1/62
Then plug in m into one of the equations to find b
4 = (1/62)(248) + b
4 = 4 + b
b = 0
So the equation is
y = (1/62)x + 0
or
y = (1/62)x
or
y = x/62
edit: I totally didn't use point slope. It should be
y + 0 = (1/62)(x + 0)
or y = (1/62)x
(since b is 0, that means she started driving directly at home)

2) 150mi/1.25hr = Xmi/5hr
750mi/1.25 = X
X = 600miles
Answer:
24 ( 12 -3x)
Step-by-step explanation:
(4x3 + 7x2 – 2) (2x2 – 3x + 8)
(12 + 14 - 2) (4 - 3x + 8)
(26-2) (12 - 3x)
24 (12 -3x)
Answer: 11.4
Step-by-step explanation:
area of rect. = 24
area of circle (half circle+half circle = full circle) = pi*r^2 = pi*(2*2) = pi*4 = about 12.57
2 = radius since 4 = diameter
24-12.57 = 11.43
round = 11.4
Answer:
$2280
Step-by-step explanation:
Given: Cost of Air conditioner= $3000.
Rate of depreciation= 8%
Number of year= 3 years.
Now, finding the depreciation for 3 years.
Depreciation= 
Amount of depreciation= 
∴ Amount of depreciation in 3 years is $720.
Cost of Air conditioner after 3 years= 
⇒ Cost of Air conditioner after 3 years= 
∴ Cost of Air conditioner in 3 years is $2280.
