-6(2+a) = -48
Distributive property
-12 -6a = -48
Add 12 to both sides
-6a = -36
Divide both sides by -6 and you get a= 6

Answer with explanation:

The given equality or expression in one variable is,

⇒  -6×(2+a)= -48

⇒ -6×(2+a)= -6× 8

Dividing both sides by , -6 we get

⇒ 2+a=8

Subtracting , 2 from both sides

⇒2+a-2=8-2

⇒a=6

Find the equation of a line parallel to y - 5x = 10 that passes through the point (5,1)
xenn [34]

Answer:

y=5x-24

Step-by-step explanation:

First step find the slope of y-5x =10

Add 5x on the right side

y=10+5x

Slope is 5

Second step plug in (5,1)into point slope form:

y-y₁=m(x-x₁)

M is 5 cause thats slope

y-1=5(x-5)

distrubte 5

y-1=5x-25

add 1

y=5x-24

Pls help, thank you

Answer:

  • y = -3x² + 7x - 9

Step-by-step explanation:

<u>Given quadratic function:</u>

  • y = ax² + bx + c

<u>Points on the graph:</u>

  • (-2,-35), (1,-5), (3,- 15)

<u>Substitute values of x and y and solve the system of equations:</u>

  • -35 = a(-2)² + b(-2) + c ⇒ -35 = 4a - 2b + c   ⇔ eq 1
  • -5 = a(1)² + b(1) + c ⇒ -5 = a + b + c               ⇔ eq 2
  • -15 = a(3)² + b(3) + c ⇒ -15 = 9a + 3b + c       ⇔ eq 3

<u>Subtract eq 2 from eq 1:</u>

  • -35 - (-5) = 4a - 2b + c - a - b - c
  • -30 = 3a - 3b
  • b = a + 10                                                         ⇔ eq 4

<u>Subtract eq 2 from eq 3:</u>

  • -15 - (-5) = 9a + 3b + c - a - b - c
  • -10 = 8a + 2b
  • b = -4a - 5                                                       ⇔ eq 5

<u>Compare eq 4 and eq 5, solve for a:</u>

  • a + 10 = -4a - 5
  • a + 4a = -5 - 10
  • 5a = -15
  • a = -3

<u>Find the value of b using eq 4:</u>

  • b = -3 + 10
  • b = 7

<u>Find the value of c using eq 2:</u>

  • -5 = -3 + 7 + c
  • c = -5 - 4
  • c = -9

<u>We now have a, b and c:, the function is:</u>

  • y = -3x² + 7x - 9
