Since it was stated that the equation is linear, therefore
we can use the slope point formula to find for the slope and intercepts. The
linear equation has a form of:
y = mx + b
where y is the retail price, x the wholesale price, m the
slope and b the y-intercept
m = (y2 – y1) / (x2 – x1)
m = (238 – 112) / (175 – 85)
m = 1.4
So the equation now becomes:
y = 1.4x + b
Plugging in any pair to find for b:
112 = 1.4(85) + b
b = -7
So the full equation is:
<span>y = 1.4x - 7</span>
<span>or</span>
<span>R = 1.4C - 7</span>
The first thing we need to do is combine like terms
6c+14=-5c+4+9c
6c+14=4c+4
-4c -4c
2c+14=4
-14 -14
2c=-10

2 2
c=-5

Answer:
5.5+106 square inches
Step-by-step explanation:
The wooden frame has different shapes- semi circle, rectangles and we would have to calculate area of all the shapes to get the wood required.
To get area of the circle, we use the formula π(R²-r²)/2. Subtract the inner radius from the outer radius =
π(6²-5²)/2= 11π/2
=5.5π square inches
We add area of the semi circle to area of the 3 rectangles from the diagram:
2×1×48×10×1=106 square inches
The rectangle with 10 inches is because we subtracted one inch from both sides of the 12 inches rectangle to avoid repetition and overvaluing the area
Total area =5.5π +106 square inches
Options must have ommitted the "π"
1.5 if you put 2.25 in the calculator and hit the check mark looking symbol it will tell u its 1.5
