The slope (m) of the line graphed is -4/2, because the line goes down 4 (-4) and over 2 (+2), which is change in y over change in x
m = -4/2 = -2
the y-intercept (b) of the line = -1, because the line crosses the vertical line at x=0 at y=-1
now for the equation:
y = mx + b
y = -2x + -1 = -2x - 1
f(x) = -2x-1
the last answer is correct

There were 25 adults and 15 children at a restaurant. what percent of the people were children?

Arada [10]

Answer:

37.5 percent

Step-by-step explanation:

Well, there are 25+15=40 total people. Since there are 15 children, the percent is 15/40, which is equal to .375

Because percent is by hundredths, multiply by 100 by moving the decimal to the right twice, and you have a percentage of 37.5.

1) Area of trapezoid =1/2(base 1 +base 2)* height

$A= \frac{23 \frac{1}{3}+4 \frac{2}{3} }{2} *(12 \frac{3}{4} ) = \frac{27 \frac{3}{3} }{2} *( \frac{51}{4} ) = \frac{28}{2} * \frac{51}{4} = \frac{7*51}{2} = \frac{357}{2} =178 \frac{1}{2} x^{2}$
