Answer:

for second question

first length is 9cm

Area=l*b

= 9cm *9cm

=81<em><u>cm</u></em>

then, For semicircle

radius is 9 cm

area= 1/2*9cm

now , area of two semi circle = 2*1/2*9

= 9 cm

now area of shaded = 81-9

=72

5. For Which value of x is line L parallel to line m?

laiz [17]

Answer:

$x=22$

Step-by-step explanation:

we know that

If line l is parallel to line m

then

$130\°+(2x+6)\°=180\°$ -----> by supplementary angles (consecutive interior angles)

solve for x

$136+2x=180$

$2x=180-136$

$2x=44$

$x=22$

-5 (p+2)=2 (2p-15)+p

Bess [88]

$-5 (p+2)=2 (2p-15)+p$

$-5p-10=4p-30+p

$ $\text{Expand}$

$-5p-10=5p-30
$

$-10=5p-30+5p
$ $\text{Add 5p to both sides}$

$-10=10p-30

$

$-10+30=10p
$ $\text{Add 30 to both sides}$

$20=10p
$

$\dfrac{20}{10}=p$ $\text{Divide both sides by 10}$

$p=2$ $\text{Solution}$

What is the equation of a line that has a slope of - 1/2 and a y intercept of 3

Alla [95]

y = ½x +3

Step-by-step explanation:

Slope = m = ½

y-intercept = 3

Substitute values into Slope intercept form :

$y = mx + b$

Where m = slope

b = y intercept

$y = \frac{1}{2} x + 3$

mina [271]

Answer:

Sketch the graph of y=7^x

Reflect the graph across the y-axis to show the function y=7^-x

Stretch the graph vertically by a factor of 3 to show the function y=3*7^-x

Shift the graph up 2 units to show the function y=3*7^-x+2
