Answer:

The solution is (1, 1).

Step-by-step explanation:

y = -2x + 3

y = 5x - 4

Substitute y = 5x - 4 in the first equation:

5x - 4 = -2x + 3

5x + 2x = 3 + 4

7x = 7

x = 1

Now substitute x = 1 in the first equation:

y = -2(1) + 3

y = -2 + 3

y = 1.

A hose fills a hot tub at a rate of 2.58 gallons per minute. How many hours will it take to fill a 268-gallon hot tub?

kakasveta [241]

Answer:

1.73 hours

Step-by-step explanation:

This can be solved with proportions.

$\frac{2.58 gallons}{1 minute} = \frac{268 gallons}{x minutes} \\$

Cross multiply and you get:

$2.58x gallons * minutes = 268 gallons * minutes\\$

Divide by 2.58 gallons and you get:

$x minutes = \frac{268 gallons}{2.58 gallons} * minutes \\x minutes = 103.876 minutes\\x = 103.876 minutes\\$

And to find out the number of hours that is, divide by 60 and you get 1.73 hours.

Which binomial is a factor of x^2 + 2x - 15

Shalnov [3]

Answer:

(x−5)(x+3)

Step-by-step explanation:

To factorise, we firstly need two brackets, each containing an x.

(x)(x)

This creates the x2 term.

Now we need to get the rest of the terms. To do this, we need two factors of −15 which will add/subtract to give us +2

The two factors that do this are −3 and 5, as −3+5=2

∴(x−3)(x+5)

You can check by expanding it out.

Given the points (-2, 0), (-1,0), (0, – 8), (2, 0), write the polynomial in factored form.

Ket [755]

As per given by the question,

There are given that four point.

The point is,

$(-2,\text{ 0), (-1, 0), (0, -8), (2, 0)}$

Now,

From given point,

$(-2,\text{ 0), (-1, 0), (0, -8), (2, 0)}$

Then, the factor is,

$(x+2)(x+1)(x-2)$

Now, solve the above equation,

$(x+2)(x+1)(x-2)$

The factorial formd will be,

$y=a\times(x+2)\times(x+1)\times(x-2)$

Now, find the value of "a" with the help of given point (0, -8).

So,

Puth the value of x =0, and y=-8 in above equation,

Then,

$\begin{gathered} y=a\times(x+2)\times(x+1)\times(x-2) \\ -8=a\times(0+2)\times(0+1)\times(0-2) \\ -8=a(2)(1)(-2) \\ a=\frac{-8}{-4} \end{gathered}$

Then, a=2.

Now,

The value of a is 2.

And,

The polynomial in the factored form is,

$y=2(x+2)(x+1)(x-2)$

Hence, the value of a is 2 and the polynomial in the factored form is,

$y=2(x+2)(x+1)(x-2)_{}$
