Assuming the question is to find the area, the answer is 27.5(unit)^2.

I've given you the answer, but I'm also going to give you an explanation in case you decide that you want to learn how to do it.

This is a trapezium.

To find the area of a trapezium, the first step is to add A and B (the top and bottom) and then half it. In this case, it would be (4+7)/2 = 5.5.

The second and last step is to multiply that product (1/2(a+b) or 5.5 in this case) by the vertical height (5 in this case).

Write the equation of the line in fully simplified slope-intercept form

DochEvi [55]

Answer:

y = 3x - 7

Step-by-step explanation:

Slope - Intercept Form : $y = mx+b$

$m$ = slope

$b$ = y - intercept

Slope = $\frac{rise}{run}$

= $\frac3{1}$

= $3$

So far: $y = 3x + b$

Plug in a point from the graph, ex. (3,2)

$2 = 3(3) + b\\\\2 = 9 + b\\\\b = -7$

Equation : $y = 3x - 7$

Identify the value of a if

Serga [27]

Answer:

a=1/3

Step-by-step explanation:

from the point on the graph

x=4 and y=8

substitute them into the equation:

y=a(x-2) (2x+4)

you will get

8=a(4-2) (2(4)+4)

8=a(2) (8+4)

8=a(2) (12)

8=2a×12

8=24a

divide both sides by 24

8/24=24a/24

1/3=a or a=1/3

The battery on McKenzies old computer can last 4(1/5) hours. She bought a new computer that has a battery that can last 40% long

Solnce55 [7]

Answer:

$5\frac{22}{25}\ hours$

Step-by-step explanation:

we know that

$4\frac{1}{5}\ hours=\frac{4*5+1}{5}=\frac{21}{5}\ hours$

$100\%+40\%=140\%=\frac{140}{100}$

Let

x ------> new battery life

The equation that represent this situation is

$x=\frac{140}{100} (\frac{21}{5})=\frac{2,940}{500}\ hours$

convert to mixed number

$\frac{2,940}{500}=\frac{2,500}{500}+\frac{440}{500}=5\frac{22}{25}\ hours$
