4x^2 + 16x-2= 5x
Minus 16x over
4x2-2= -11x
Add 11x over
4x^2 +11x -2
Use quadratic formula x= 2.9
I’m not sure here. I tried my best. Hope it helps!
Its 18....................................
Could you do 31 add 31 which would also be 31 multiplyed by 2
hope this helps
Answer:
180 plants
Step-by-step explanation:
the area of a right triangle is: ab/2
side a = 8
side b = 15
8 x 15 = 120
120/2 = 60
Michael wants 3 plants for every square yard (multiply by 3)
60 x 3 = 180
Slope intercept form is y = mx + b.
Y = coordinate y.
M = Slope
X = coordinate x.
B = y-intercept.
Slope formula: (y2-y1) / (x2-x1)
Plug in: (-1 - 7) / (4 - 2) = -4.
We can just insert the pair (2,7) as our x and y to solve b.
7 = -4(2) + b.
Solve for b.
7 = -8 + b.
-b = -8 -7
-b = -15
b = 15.
Original equation:
y = mx + b
y = -4x + 15
