Answer:

Step-by-step explanation:

It's a right triangle, so the pythagorean theorem will be used a lot.

First, find the side length on the left.

25^2 = 7^2 + y

y = 24

Now, knowing that 7 - 3 = 4 (the smaller side length), I can use this theorem again to find x.

4^2 + 24^2 = x^2

x = $\sqrt{592}$

Just need to simplify it a little farther...

592 / 16 = 37, so B must be the answer.

A particular shoe store stocks two styles of walking shoes. Style A sells for $66.95 and Style B sells for $84.95. At the end of

Gnom [1K]

Answer:

Style A shoes sold : 152

Style B shoes sold : 88

Step-by-step explanation:

Let :

Style A shoes = x
Style B shoes = y

Forming equations :

x = 2y - 24
66.95x + 84.95y = 17,652

Substitute the value of x from 1 in 2.

66.95 (2y - 24) + 84.95y = 17,652
133.90y - 1606.80 + 84.95y = 17,652
218.85y = 19258.80
y = 88

Finding x :

x = 2(88) - 24
x = 176 - 24
x = 152

Solution :

Style A shoes sold : 152
Style B shoes sold : 88

Explain how you could write a quadratic function in factored form that would have a vertex with an x-coordinate of 3 and two dis

Elena-2011 [213]

Answer:

$f(x) = (x + 1)(x - 7)$

Step-by-step explanation:

For a quadratic function to have a vertex with an x-coordinate of 3, then

$3 = - \frac{b}{2a}$

Let a=1, then we have

$3 = - \frac{b}{2}$

$b = - 2 \times 3 = - 6$

So now our equation becomes:

$f(x) = {x}^{2} - 6x + c$

We now find two factors of c that add up to -6.

Let these factors be 1, and c.

Then

$c + 1 = - 6$

$c = - 6 - 1 = - 7$

Therefore the factors are :

1 and -7.

The function becomes:

$f(x) = {x}^{2} - 6x - 7$

The factored form is

$f(x) = (x + 1)(x - 7)$

The difference of two trinomials is x2 − 10x + 2. If one of the trinomials is 3x2 − 11x − 4, then which expression could be the

bulgar [2K]

Answer: $4x^2-21x-2$ .

Step-by-step explanation:

Given: The difference of two trinomials is $x^2 -10x + 2$ . If one of the trinomials is $3x^2 - 11x - 4$ .

Then, the other trinomial will be ( $3x^2 - 11x - 4$ ) + ( $x^2 -10x + 2$ )

$=3x^2-11x-4+x^2-10x+2\\\\=3x^2+x^2-11x-10x-4+2\\\\=4x^2-21x-2$

Hence, the other trinomial could be : $4x^2-21x-2$ .
