A line that passes through the points (−5, 7) (10, 1). Using the mx+b format
lianna [129]

Answer:

y=2x-19

Step-by-step explanation:

I'm guessing you mean slope intercept form y=mx+b

If so, first you would have to find the slope of the line

To do that, use the formula y2-y1/x2-x1

Remember you can pick any coordinate pair for this

I will pick 1=y2 -5=y1 10=x2 and 7=x1

When I put that in the equation I get 1-(-5)/10-7

Overall I get 6/3, or 2

Now to find the y intercept, you plug in the slope and one of the coordinates(any is fine)

I will pick (10,1)

1=y and 10=x and 2=m

1=2(10)+b

this simplifies to 1=20+b

now subtract 20 from both sides and get -19 = b

Now you have your equation y=2x-19

If m(x) = x2 + 3 and n(x) = 5x + 9, which expression is equivalent to (mn)(x)?
Ilia_Sergeevich [38]
For this case we have the following functions:
 m (x) = x ^ 2 + 3

n (x) = 5x + 9
 Multiplying both functions, we obtain an expression equivalent to (mn) (x).
 We have then:
 (mn) (x) = m (x) n (x)

 Substituting values we have:
 (mn) (x) = (x ^ 2 + 3) (5x + 9)

 Rewriting the expression we have:
 (mn) (x) = (5x ^ 3 + 15x) + (9x ^ 2 + 27)

(mn) (x) = 5x ^ 3 + 9x ^ 2 + 15x + 27
 Answer:
 
An expression that is equivalent to (mn) (x) is:
 (mn) (x) = 5x ^ 3 + 9x ^ 2 + 15x + 27
