First we need the slope, which we can get using (y2 - y1) / (x2 - x1)
Plug in our coordinates and we get
(15 - 12) / (2 - -4)
3 / 6
1 / 2
So, our slope is 1/2.
Then, we take 1/2 of one of our x values, say, 2, and we get 1. How do we go from 1 to 15? We add 14. So our y - intercept is 14.
All this plugged into y = mx + b gives us the equation y = 1/2 x + 14
Answer:
14*7=98 (Original area)
28*14=392 (New area)
The area of the new one is 4 times the original, since the width and length wee doubled.
28 is the doubled amount of 14. 14 is the doubled amount of 7.
Please but brainliest if you can.
Answer:
Step-by-step explanation:
hello :
the area is : (3x+4y)²cm² when :x=4 and y=1, the area is : (3(4)+4(1))²cm² =16²cm2=256cm²
f(x) = -3x + 6
y = -3x + 6
x = -3y + 6
x - 6 = -3y
-3 -3
⁻¹/₃x + 2 = y
⁻¹/₃x + 2 = f⁻¹(x)
g(x) = x + 2
y = x + 2
x = y + 2
x - 2 = y
x - 2 = g⁻¹(x)
