morpeh [17]

Answer:

Not a solution.

Step-by-step explanation:

-6x + 6y = - 9\\\rule{150}{0.5}\\-6(\frac{1}{2}) + 6(2) = -9\\\\-3 + 12 = -9\\\\9 =-9

The final result is a contradiction. It is not a solution to the equation, and therefore, will not be on the line.

FInd the slope of the line passing through the points (0,4) and (-8,-1)
Yuliya22 [10]

We can use the slope formula:

\frac{y.2 - y.1}{x.2 - x.1} = m

By plugging the values into this formula, we can solve for the slope.

-1 - 4 / -8 - 0

-5 / -8

Because there are two negatives, they cancel out;

The slope is 5/8

5. The area of the trapezoid is 75 square inches. Find the height of the trapezoid. And it’s two bases are 10 and 15.
Sphinxa [80]

Answer:

The answer is 6

Step-by-step explanation:

A=½(b1 + b2) h

we substitute

Area=75

the two bases are 10 and 15

75=½(10+15) h

75=½(25)h

75=(1*25/2)h

75= 25h/2

75/1= 25h/2

25h*1= 75*2

25h= 150

we divide by 25

25h/25= 150/25

h=6
