The answer if less you mean subtraction is 3d2 + d + 1
-20+13=-7 , -7 multiplied by -3 equals 21
Answer:
16x² - 8x + 8
Step-by-step explanation:
f(x)=4x-1
g(x)=x²+7
g(f(x)) = g(4x-1) = (4x - 1)² + 7 = 16x² - 2*4x*1 +1² + 7= 16x² - 8x + 8
Answer:
Point Slope: (y + 1) = 2x
Slope Intercept: y = 2x - 1
Step-by-step explanation:
I'll do it in two forms.
Slope = (3 + 1) / (2 - 0) = 2
Point - Slope: (y + 1) = 2x
Slope Intercept: y = 2x + b
-1 = b
y = 2x - 1
To find the perimeter of a triangle, you need to find the length of each side and add all of them to find the perimeter. To find the distance between two points you use the distance formula with d as the distance between two coordinates, (x1,y1) and (x2,y2). , Hope this helps.
