When you know the area and one side of a rectangle, divide the area by the known side to find the length of the other side.
Length = 63/6
Length = 10.5 inches
Answer:
50.24
Step-by-step explanation:
Area of a circle= πr^2
Where we will take radius as 4cm and pi as 3.14 approx
= 3.14 x 4 x 4
= 3.14 x 16
= 50.24
So the area is 50.24 cm^2
Answer:
$45
Step-by-step explanation:
The final sales price is the regular price less the $10 discount:
$55 - $10 = $45
Answer:
-16
Step-by-step explanation:
x/-2 = 8
cross multiply.
-2(-2) = 0 (because you're cross multiplying)
8(-2) = -16
x= -16
Answer:
y = 2x + 5
Step-by-step explanation:
First, you must choose two ordered pairs from the table to solve for the slope (m):
Let (x1, y1) = (0, 5)
(x2, y2) = (1, 7)
Substitute the given values into the following slope formula:
Therefore, the slope (m) = 2.
The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates (0, <em>b </em>). It is also the value of y when x = 0. Looking at the given table, (0, 5) reflects the description of the y-intercept. The y-intercept (b) is the y-coordinate of (0, 5).
Given the slope (m) = 2, and y-intercept (b) = 5, the linear equation is:
y = 2x + 5
