Answer:

<u>Standard form</u>:  -3x + y = 25

Step-by-step explanation:

y=mx+b

y = 3x + 25    ... you want to convert to standard form (Ax+By=C)

-3x     -3x       ... you want the variables on the left side of the equation

-3x + y = 25

We need to find an equation in the form y=mx+b.

To find m, we use the formula:
m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

We'll use the points (0, 25) and (4, 37):
m=\frac{37-25}{4-0}=\frac{12}{4}=3

The value of b (the y-intercept) is the value of y when x=0, which is 25.

So the equation is y=3x+25 (choice A).

barxatty [35]

Answer:

1\frac{1}{4}\ liters

Step-by-step explanation:

step 1

Convert mixed number to an improper fraction

1\frac{3}{5}=\frac{1*5+3}{5}=\frac{8}{5}

step 2

Using proportion

\frac{2}{(8/5)}\frac{liters}{doors} =\frac{x}{1}\frac{liters}{door}\\ \\x=2/(8/5)\\ \\x=10/8\ liters

step 3

Convert to mixed number

\frac{10}{8}\ liters=\frac{8}{8}+\frac{2}{8}=1\frac{1}{4}\ liters

Triangle ABC has two known angles. Angle A measures 55 degrees. Angle B measures 30 degrees. What is the measure of angle C? Sho
alina1380 [7]

Answer:

According to triangle theorems, we know that the interior angles of a triangle equals 180 degrees. Since we know that angle A and angle B are 55 and 30 degrees, all we need to do is add them up and subtract it from 180 degrees to find out the measure of angle C.

55 + 30 = 85 degrees

180 degrees - 85 degrees = 95 degrees (this is the measure for angle C)

Sail with the equation by completing the square x^2+8x=-3
maxonik [38]

Answer:

The solutions are x=-4(+/-)\sqrt{13}

Step-by-step explanation:

we have

x^{2} +8x=-3

Complete the square. Remember to balance the equation by adding the same constants to each side

x^{2} +8x+16=-3+16

x^{2} +8x+16=13

Rewrite as perfect squares

(x+4)^{2}=13

square root both sides

x+4=(+/-)\sqrt{13}

x=-4(+/-)\sqrt{13}
