Answer:
y = 2x + 15
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = 2 , then
y = 2x + c ← is the partial equation
to find c substitute (- 4, 7 ) into the partial equation
7 = - 8 + c ⇒ c = 7 + 8 = 15
y = 2x + 15 ← equation of line
Answer:
Factoring
Step-by-step explanation:
x^2 + 7x = x(x + 7) = 0
So
x = 0 or x = -7
the x s are the independent variable so any direct change to them is changing the independent. like the second one has -5 on the x
Answer:
1. -2w-1 cuz when in parethese it all become negative. 2. factors of 32 is 1,2,4,8,16,32. and factors of 24 is 1,2,3,4,6,8,12,24. and the way you should write 32k+24 is 4(8k+6)
