Given the equation 5x2 − 20x + 15 = 0, what are the values of h and k when the equation is written in vertex form a(x − h)2 + k

= 0?
h = 2, k = 17

h = 2, k = −5

h = 1, k = 3

h = −1, k = −3

Write an equation of a line that is parel to 3/4x + 1 and passes through the point (4, -2).
Alenkinab [10]

Parallel lines have the same slope.

We have the line y = 3/4x + 1.

Then the equation of a parallel line is y = 3/4x + b.

The line passes through the point (4, -2). Put the coordinates of the point to the equation of a line:

-2 = 3/4(4) + b

-2 = 3 + b      <em>subtract 3 from both sides</em>

-5 = b

<h3>Answer: y = 3/4x - 5</h3>

Can anyone please help me :)
Solnce55 [7]

Answer:

5 to the 15th power.

Step-by-step explanation:

PEMDAS requires us to do parenthesis, then exponents, and then division. Let's do 5³. 5x5x5 is equal to 125. Now, we find 125 to the ninth power. According to my calculations, 125 to the ninth power is equal to 7,450,580,596,923,828,125. Now, we find 5 to the twelfth power, which, according to my calculations, is 244,140,625. Now, we solve. According to my calculations, 7,450,580,596,923,828,125/244,140,625 is equal to 30,517,578,125. 30,517,578,125 is equivalent to 5 to the 15th power. That means that the second option is correct. I hope this helps!
