Answer:
see explanation
Step-by-step explanation:
Use the points to find a and b, that is
(2, 18)
18 = a
→ (1)
(4, 162)
162 = a
→ (2)
divide (2) by (1)
= 
= 9
b² = 9 ⇒ b = 3
substitute b = 3 into (1)
18 = 9a ⇒ a = 2
y = 2
← exponential equation
3/4(x) + 5 - 1/2(x) = 3
If x = -8 then,
3/4(-8) + 5 - 1/2(-8)
-6 + 5 - (-4)
-6 + 9
3 = 3
Your answer would be that x = -8
You're welcome.

Answer:
4760
Step-by-step explanation:
Simple interest= principal× time ×rate/100
=3500×4×9/100
= 1260
Amount that will be in the bank after 4years= 3500+1260
=4760
First find the slope:
The slopes of perpendicular lines must multiply to -1.
-9m = -1 ----> m = 1/9
Next, use point-slope form:
y - y1 = m(x-x1) , where given point (0,5) is (x1,y1)
y - 5 = (1/9)(x - 0)
Finally, solve for y to put it in slope-intercept form:
y = (1/9)x + 5
