Step-by-step explanation:

Hey there!!

It 's so simple.

You remember common property of triangle. (i.e sum of interior angle of a triangle is 180°)

So,

77° + 31° + x = 180°

x + 108° = 180°

x = 180° - 108°

Therefore the measure of angle x is 72°.

Hope it helps....

The graph of a linear function intersects with the x axis at a point with an abscissa of 4 and with the y axis at a point with a

Leni [432]

We know that

points are
x intercept
A (4,0)

y intercept
B (0,11)

step 1
find the equation of a line
m=(y2-y1)/(x2-x1)--------> m=(11-0)/(0-4)------> m=-11/4

with m and the point B (0,11)
y-y1=m*(x-x1)
y-11=(-11/4)*(x-0)---------> y=-(11/4)x+11

the answer is
the formula of the function is
y=-(11/4)x+11

see the attached figure

You purchase a pair of shoes from the store for $42.00. You have a coupon for 20% off. How much is the discount?

Leona [35]

The discount is $8.40. Just multiply 42 by 20 and you get 840 then move the decimal two places to the left.

If 2 = 6, 3 =12, 4 = 20, 5 = 30, 6 = 42 then 9 = ?

Soloha48 [4]

At first you may get confused but look at those numbers carefully :)

as you see first result is divisible buy one of the product (second product in all cases is unknown)
so let's check where it will lead us :)

$6/2=3$

$12/3=4$

$20/4=5$

$30/5=6$

$42/6=7$

Now you can clearly see that every number was multiplied by number 1 higher than itself.
$2*(2+1)=6$

$3*(3+1)=12$

$4*(4+1)=20$

etc...

it means that after equation sign there should be $90$ because

$9*(9+1)=90$ :)

Answer:

v = 55

Step-by-step explanation:

Plug in the values provided into the equation

v = u + at

v = 23 + 8 * 4

Solve

v = 23 + 8 * 4

v = 23 + 32

v = 55
