I need help with this math problems
Solving Linear-Quadratic Systems

1. y = x^2 + 4x + 5

y = x – 5

2. y = x^2 - 2x – 7

y = x – 3

3. y = x^2 - 4x + 5

y = 3x – 1

4. y = x^2 – 16

y = x – 14

5. y = x^2 - 4x – 5

y = 5x + 5

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
