Solve for x. -5x + 13 = -17
Lana71 [14]

Subtract 13 from both sides

-5x = -17 - 13

Simplify -17 - 13 to -30

-5x = -30

Divide both sides by -5

x = -30/-5

Two negatives make a positive

x = 30/5

Simplify 30/5 to 6

<u>x = 6</u>

Which is the equation of the parabola?
mestny [16]

Answer:

  • y = -1/20(x + 3)²

Step-by-step explanation:

<u>Consider the parent function:</u>

  • y = x²

The graph of the function open up and the vertex is at the origin, the point (0, 0)

Now, if it opens down, it means it is a reflection of the parent function over x axis, hence it has a negative coefficient, the function becomes:

  • y = -x²

The vertex is shifted to the point (-3, 0). It means the function also translated left by 3 units, the function becomes:

  • y = -(x + 3)²

<u>Since all the options have 1/20 as a coefficient, our function is:</u>

  • y = -1/20(x + 3)²

This is option B

I really need help with this 6th grade work due today
DIA [1.3K]

5

Step-by-step explanation:

Length (L) = u

Breadth (b) = 6 mi

Perimeter (P) = 22 miles

Now we know

P = 2 (L+ b)

22 = 2 ( u + 6)

11 = u + 6

11 - 6 = u

u = 5
