Find the quadratic function that has roots of -9 and 3 and a vertex of (-3,-36)

1 answer:

6 0

Y=(x+9)(x-3)+c
∵(-3,-36)lies on it.
-36=(-3+9)(-3-3)+c
-36=(-6)(-6)+c
-36=36+c
c=-36-36=-72
y=(x-9)(x+3)-72
y=x^2+3x-9x-27-72
y=x^2-6x-99

If PR = 5x – 3 and QS = 3x – 5 and QS == PR, what are the length of the diagonals?

OleMash [197]

Answer:

Step-by-step explanation:

5x - 3 = 2(3x - 5)

5x - 3 = 6x - 10

6x - 5x = 10 - 3

x = 7

QS = 3(7) - 5 = 16 units

PR = 5 × 7 - 3 = 32 units

XD Plzzzzzz do 2 slides (4 problems)

Leya [2.2K]

Answer:

Slide 1:

1. Solution = (-3,2)

y = 2x - 1

y = 3/2x + 6

2. No solution

y = -4/2x + 4

y = -4/2x - 5

Slide 2:

3. Solution = (1, -6) ONE SOLUTION

4. Solution = (-4, -1) ONE SOLUTION

p.s i attached the graphs for problems 3 and 4. The first picture is for problem 3 and the second picture is for problem 4

I really hope this helped :)

I NEED HELP ASAP!!!! PLEASE HELP!!!

IRISSAK [1]

Answer:

y= 2x-3 m=2 b= -3

Step-by-step explanation:

we distribute 2(x-2)

y-1 = 2(x-2)

y-1 = 2x-4

then add one to both sides

y-1= 2x -4

+1 +1

since it is negative four and you are adding one it would be -3

y= 2x -3 that is your slope intercept form.

y= mx +b so m=2 and b= -3
