\text{Hello there! :]}

\large\boxed{125 \text { vases}}

\text{To solve, find the proportion of successes from the total:}\\\\20 / 25 = 4 / 5\\\\\text{Set up a proportion to find the # of vases necessary to complete 100 successfully:}\\\\\frac{20}{25}  = \frac{100}{x} \\\\\text{Cross multiply to solve:}\\\\20 * x = 100 * 25\\\\20x = 2500\\\\\text{Divide both sides by 20:}\\\\x = 125 \text{ vases}

What is the equation of the line, in general form, that passes through point (-1, -1) and is parallel to the line whose equation
lara31 [8.8K]

ANSWER

x + y + 2 = 0

EXPLANATION

The given line passes through;

(-1,-1) and it is parallel to x + y = 3.

This line given to us can be rewritten as

y=-x+1

It has slope m=-1.

The line parallel to this line also has slope m=-1.

We obtain the equation of the line using the formula:

y-y_1=m(x-x_1)

We substitute the slope and the point to obtain:

y -  - 1 =  - 1(x -  - 1)

y + 1 =  - 1(x + 1)

y =  - x - 1 - 1

The equation of the line is

x + y + 2 = 0

−4(m+3)=24<br> What does m=
Ket [755]

Answer: m= -9

Step-by-step explanation: First use distributive property, -4(m) is -4m and -4(3) is -12. Then you have -4m -12 =24. Then use 12 and add it to the other side of the equation, cause of the subtraction sign, 12+24=36. Then you have -4m=36. Then divide the 4 to get the m by its self. 36 divided by -4 is -9. Your answer is m=-9

Hope this helps :)
