We are given that 4 units = 320 ft. This implies that 1 unit = 80 ft. We count the other base to be 9 units = 720 ft, and the height to be 5 units = 400 ft. Using the formula for the area of a trapezoid, $\frac{400(320+720)}{2}=208,000$ , which is C

Find The slope of the line described<br> by x+2y=8

Harman [31]

Answer:

$Slope = m = \frac{-1}{2}$

Step-by-step explanation:

The equation of a line in slope-intercept form is.

$y = mx + b$ ----->(eq 1)

∴ m is slope

$x+2y=8$

subtract x from both sides.

$x - x +2y= - x + 8$

$2y= - x + 8$

divide - 2 on both sides

$\frac{2y}{2} = \frac{ - x + 8}{2}$

$y = \frac{ - x}{2} + \frac{8}{2}$

$y = \frac{ - 1}{2}x + 4$ ----->(eq 2)

By comparing (eq 1) and (eq 2)

$m = \frac{-1}{2}$

$Slope = m = \frac{-1}{2}$

3x+1/10=x-1/7 what is x explain how you got the answer

777dan777 [17]

3x+1/10=x-1/7 subtract 1/10 from both sides 3x=-1/7-1/10+x subtract x from both sides 2x=-1/7-1/10 add -1/7 and -1/0 1/7=10/70 1/10=7/70 -10/70-7/70=-17/70 2x=-17/70 divide by 2 ro multiply by 1/2 x=-17/140
