y = 4x -3
Find the y-intercept; (0, -3). Plug this coordinate's y-value in for the b (y = mx + b).
Now, find two points on the line to do slope formula, or you can do rise over run. For example, if I had the points (0, -3), and (1, 1), I'd have the formula [1 - (-3)] / (1 - 0), in which the division sign represents a fraction. The simplified version of this fraction will be 4.
Plug this value in for m.
Now, your equation is y = 4x - 3
Answer:
W = 16
L = 24
Step-by-step explanation:
Let's write down the information we have first
"The length of a rectangle is 8 feet longer than it is wide"
L = W + 8
"If each side is increased 8 feet, then the area is multiplied by 2."
(L + 8)(W + 8) = 2LW
Now we can solve for W first, then L
(W + 16)(W + 8) = 2W(W + 8)
W² + 24W + 128 = 2W² + 16W
0 = W²- 8W - 128
0 = (W - 16)(W + 8)
W = 16
L = 24
(This part above is solved like quadratics)
Answer:
Area = 10 in
Step-by-step explanation:
Base=4 in , Height=2 in , Other Side = 3 in.
Height x Other Side + Base
2 x 3 + 4
2 x 3 = 6 + 4 = 10
Answer:
y = 5x - 3
Step-by-step explanation:
Asim's age = x
Mother's age = y
y = 5x - 3
or y = 5x - 3
x = 7
y = 5(7) - 3
y = 35 - 3
y = 32
