Answer:
25m
Step-by-step explanation:
Area = Side²
Side = √Area
= √625
= √25 x 25
= 25 m
Answer:
Two solutions (-4,-7) and (4,7)
Step-by-step explanation:
x = y + 3
x*y = 28
(y+3)*y=28
y^2+3y-28=0
(y+7)(y-4)=0
y=-7, y=4
x=-4, x=7
Answer:
x = 0, y = -1
Step-by-step explanation:
10x = 5y + 5
y = 2x - 1
======================
10x = 5(2x - 1) + 5
10x = 10x - 5 + 5
x = 0
======================
y = 2x - 1
y = -1
Vertex coordinates: (h, k)
Vertex form: y = a(x-h)^2 + k
y = 2(x+3) + 2(x+4)
Use distributive property:
y = 2((x+3)+(x+4))
Simplify:
y = 2(2x+7)
y = 4x+14
This is slope - intercept form, not vertex form. Vertex form is for quadratic equations - this is a linear equation.
Answer (in slope - intercept form):
y = 4x+14
