Answer:
y=4x-3
Step-by-step explanation:
y=(slope)x+b
y=4x+b
Insert Point:
Answer:
(x+4)(x+2)
Step-by-step explanation:
Distributive property of 2 binomials:
First, outer, inner, last
(a+b)(c+d) = ac+ad+bc +bd
Factor x^2 into x*x
Factor 8 into 2*2*2
Find what two numbers add up to 6 and multiply to get 8
1 and 8 do not work because they add up to 9. 2 and 4 work because they add up to 6.
Check: (x+4)(x+2)
First: x*x = x^2
Outer: 2*x
Inner: 4*x
Last: 2*4 = 8
Add together: x^2+2x+4x+8 = x^2+6x+8
If everything is multiplying by X, then the answer is 0, because in order to find the Y intercept, you just replace X with 0, and anything times 0 is 0.
Answer:
7(n-7)
Step-by-step explanation:
it tells us that there is difference of a number and 7
a number=n
this will be (N-7)
this tells us that seven times the equation (N-7), so just multiple 7 by the equation (n-7)
7(n-7)
