We need to find the lowest values
the length is (3-0)/3=3/3=1 width
area=length times width, since all are 1, just add the heights

evaluate f(0) and f(1) and f(2) and f(3)
find the one that is the lower one and use that one
f(0)=16
f(1)=15
f(2)=12
f(3)=7

for f(0) and f(1)
f(1) is lower so the height for this one is f(1) or 15 is height

for f(1) and f(2)
f(2) is lower so height is f(2) or 12

for f(2) and f(3)
f(3) is lower so height is f(3) or 7


15+12+7=34
yep you're right

What is -2(5+6m) + 16 = -90 ?<br> Can you please show with detail
GarryVolchara [31]

Answer:

m = 8

Step-by-step explanation:

-2(5 + 6m) + 16 = -90

Start by distributing -2 inside the parentheses. This means you will multiply everything inside the parentheses (5 + 6m) by -2.

-10 - 12m + 16 = -90

Simplify the left side of the equation by combining like terms.

6 - 12m = -90

Subtract 6 from both sides of the equation to isolate the term containing the variable m and to move all other terms to the other side (right) of the equation.

-12m = -96

Divide both sides of the equation by -12 to isolate and solve for m.

m = 8

Find the slope of the line.
zubka84 [21]

to get the slope of any line, all we need is two points off of it.

so let's see hmmmmmmm this line passes through (0, 1) and hmmmm (4, -2)


\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{1})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-2}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-2-1}{4-0}\implies \cfrac{-3}{4}\implies -\cfrac{3}{4}
