Answer:

11x + 6x^2 -57

Step-by-step explanation:

(7x2 + 5)(x - 3) + 2x (3x - 4)

1. Multiply 7x2

(14 + 5)(x - 3) + 2x (3x - 4)

2. Add 14+5

(19)(x - 3) + 2x (3x - 4)

3. Distribute 2x to 3x-4

(19)(x - 3) + 6x^2 - 8x

4. Distribute 19 to x-3

19x - 57 + 6x^2 - 8x

5. Simplify.

11x + 6x^2 -57

30 points I'm struggling Find the equations of each line and show all of your work. (1, 5) (2, 6) (1, 1) (3, -8) (2, -3) (5, -2)
Free_Kalibri [48]

Answer:

1.(1,5) and (2,6) , 6-5/2-1=1/1 m=1 ,y=1x+b

5=1(1)+b 4=b

y=x+4

2.(1,1) and (3,-8) -8-1/3-1=-9/2 m=-9/2 ,y=-9/2x+b

1=-9/2(1)+b b=11/2

y=-9/x+11/2

3.(2.-3) and (5,-2) m=1/3 ,y=1/3x+b

-3=1/3(2)+b -3=2/3+b

-3-2/3=b

 b=-11/3

y=1/3x-11/3

4.(2,5)and (4,3) m=-1 y=-1x+b

5=-1(2)+b 5=-2+b

5+2=b

b=7

y=-1x+7

6.(-3,-5) and (-1,-3) m=2/2=1 y=1x+b

-5=1(-3)+b -5=-3+b

-5+3=b

-2=b

y=1x-2
