Answer:

PR = 82

Step-by-step explanation:

Since Q is the midpoint of PR, then

PQ = QR, that is

6x - 7 = 5x + 1 ( subtract 5x from both sides )

x - 7 = 1 ( add 7 to both sides )

x = 8

Thus

PR = PQ + QR = 6x - 7 + 5x + 1 = 11x - 6

Hence

PR = 11(8) - 6 = 88 - 6 = 82

If there are 150 total instruments in said Orchestra, we'll need to divide that number in half.
75, simple enough. Now we know that half of 150 is 75.
Start by writing your problem like this: 150= 75w+37.5b
That equation is all I can think of, because 37.5 is half of 75, which means that's roughly the number you're looking for. Sorry if this doesn't help much<span />

yarga [219]
The correct answer is A) 2/5

That is because the probability of it is equal to the number of numbers larger than 6 divided by 10, which is 4/10, or 2/5 when reduced.

Find the equation of a parabola that opens up and has the following x intercepts (-3,0) and (4,0)
Elenna [48]

The equation of a parabola that opens up and has the following x intercepts (-3,0) and (4,0) is y=x^{2}-x-12

<h3><u>Solution:</u></h3>

We have to find the equation of a parabola that opens up and has the following x intercepts (-3, 0) and (4, 0)

x-intercepts of the parabola are (−3, 0) and (4, 0)

So, we can form an equation:

Also x = 4

x – 4 = 0

x – 4 = 0 is another factor of quadratic equation.

The quadratic function is:

\begin{array}{l}{y=(x+3)(x-4)} \\\\ {y=x^{2}-4 x+3 x-12} \\\\ {y=x^{2}-x-12}\end{array}

Hence, the equation of the parabola is  y=x^{2}-x-12
