Which equation represents y= -x^2 + 6x + 7 in vertex form ?
Drupady [299]

we are given

y= -x^2 + 6x + 7

we can use vertex form parabola formula

y= a(x-h)^2+k

so, we can complete x square

y= -(x^2 - 6x - 7)

y= -(x^2 - 6x - 7+3^2-3^2)

y= -(x^2 - 6x +3^2-16)

y= -(x-3)^2+16

so, option-A........................Answer

0.8% of 150 is what numbers and how do you write the equation with a variable in it.
Tanzania [10]

Answer:

1.2

Step-by-step explanation:

1. First, we have to write an equation with a variable! Given 0.8%, we know that it's equal to (0.8/100), and "of" means to multiply. Therefore, the equation will looks like this: \frac{0.8}{100} * 150 = x

2. Now, let's solve for x!

  • \frac{0.8}{100} * 150 = (0.008)(150)
  • (0.008)(150) = \frac{6}{5}
  • \frac{6}{5} = 1\frac{1}{5}
  • 1\frac{1}{5} = 1.2
  • 1.2

Therefore, 0.8% of 150 is 1.2!
