(x - 4)(x + 3) = x^2 + 3x - 4x - 12 = x^2 - x - 12
Answer:
<h2>
y - 2 = -⁶/₅x</h2>
Step-by-step explanation:
The point-slope form of the equation of the line passing point <em>(x₁, y₁)</em> and with the slope of <em>m</em> is: y - y₁ = m(x - x₁)
m = -⁶/₅
Y-Intercept = 2 ⇒ point (0, 2) ⇒ x₁ = 0, y₁ = 2
Point-Slope Form: <u> y - 2 = -⁶/₅(x - 0)</u>
Let x be the amount of hours the plumber worked.
Therefore, we get:
40x+65=325
Solve for x.
40x=260
x=6.5
Therefore, the plumber worked for 6.5 hours.
5.5/2.75 is 2. Since the shadow shrinks twice the original size, we can only guess that the basketball hoop would too. This means the hoop’s shadow would be 5ft.
