Answer:
The length of Louise’s basement is <u>90 feet</u>.
Step-by-step explanation:
Given:
Louis wants to carpet the rectangular floor of his basement.
The basement has an area of 4860 square feet.
The width of the basement is 3/5 it’s length.
Now, to find the length of Louise’s basement.
Let the length of basement be
So, the width is:
Area of the basement = 4860 square feet.
Now, to get the width of basement we put formula:
<em>Multiplying both sides by 5 we get:</em>
<em>Dividing both sides by 3 we get:</em>
<em>Using square root on both sides we get:</em>
Therefore, the length of Louise’s basement is 90 feet.
Answer:
y = 3x - 7
Step-by-step explanation:
The <em>point-slope formula</em> for a straight line is
y – y₁ = m(x – x₁)
x₁ = 4; y₁ = 5; m = 3 Substitute the values
y – 5 = 3(x - 4) Remove parentheses
y – 5 = 3x - 12 Add 5 to each side
y = 3x - 7
The graph is a straight line with a y-intercept at y = -7 and a slope = 12/4 = 3.
