Step-by-step explanation:

1. Distribute the -2. multiply-2 with 5x and 8. it will be -10x-16=14+6x. For me, i make small numbers negative or positive than big ones. Add 16 to both sides. it will be -10x=30+6x. Subtract 6x. -10x-6x=-16x. Divide both sides by 16. x=30/16= 1 and 14/16

which statement best describes a line in slope-intercept form when the coefficient of the coefficient of the x term is positive

lys-0071 [83]

Answer:

The line will be going 'uphill' from left to right

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

y=mx+b

where m is the slope

b is the y-intercept

If the coefficient of the x-term is positive

then

the slope is positive

therefore

If the values of x increases, the values of y increases

If the values of x decreases, the values of y decreases

The line will be going 'uphill' from left to right

Let's put it into perspective.

x/(x+5)

If increase by 3:

(x+3)/(x+8) = 3/4

Cross multiply.

4(x+3)=3(x+8)

4x+12 =3x+24

Solve algebraically.

4x-3x = 24-12

x = 12

Therefore, original fraction is:

12/17

NeX [460]

Given:

A chemical company makes two brands of antifreeze.

The first brand is 70% pure antifreeze.

The second brand is 95% pure antifreeze.

We need to make 130 gallons of a mixture that contains 85% pure antifreeze.

Let we will use (x) gallons from the first brand

So, we will use (130 - x) from the second brand.

The mixture must contain 85% pure antifreeze.

So, we can write the following equation:

$70x+95(130-x)=85*130$

Solve the equation to find (x):

$\begin{gathered} 70x+95*130-95x=85*130 \\ -25x+12350=11050 \\ -25x=11050-12350 \\ -25x=-1300 \\ x=\frac{-1300}{-25}=52 \end{gathered}$

So, the answer will be:

First brand: 52 gallons

Second brand: 78 gallons
