Write an equation of a line perpendicular to line AB in slope-intercept form that passes through the point (7, 6).
y = 0.5x + 2.5
y = 0.5x − 2.5
y = −2x + 20
y = 2x − 20

Answers

Y=2x-20 that the answer to your question

The  equation of a line perpendicular to line AB in slope-intercept form is

[tex]y=0.5x+2.5[/tex]

Graph :

We are given with a graph of a line ABEquation of a line perpendicular to AB passes through point (7,6)

From the slope of line AB using any two points from the given line

A is (0,1)  and B is (-2,5)

lets find out slope using slope formula

[tex]slope =\frac{y_2-y_1}{x_2-x_1} =\frac{5-1}{-2-0} =-2[/tex]

Slope of perpendicular lines are negative reciprocal of one another

Slope of perpendicular line is [tex]\frac{1}{2}[/tex]

Use point slope formula to find equation of the line

[tex]m=\frac{1}{2} , (7,6)[/tex]

Point slope formula

[tex]y-y_1=m(x-_1)\\y-6=\frac{1}{2} (x-7)\\y-6=0.5x-3.5\\y=0.5x-3.5+6\\y=0.5x+2.5[/tex]

The  equation of a line perpendicular to line AB in slope-intercept form is

[tex]y=0.5x+2.5[/tex]

The United States Air Force has 19 women for every 81 men enlisted. If a squadron has 250 members, approximately how many are women?

Answers

Approximately 76
You take (250 - 81 =169)=19 so you keep doing that until you run out of members
There are 19 women for every 100 members (19 women +81 men). So you would use a calculator to divide 19 by 100, which could might be able to do in your head, and you’ll get 0.19. Now multiply that by 250 and you’ll get 47.5. Since it says approximately and you can’t have half a person, round up to 48.

Find the area of this polygon (composite figure). Remember your units.


Please have an explanation in words! (I would like to understand how to do it myself.)

Answers

So u can see a rectangle and a triangle
Area of the rectangle is 7 x 12 = 84ft
Area of the triangle= base x height divided by 2
So 6 x 12 = 72. 72/2 = 36ft
Then u add both areas
36 + 84 = 120ft
Hope this helps!
So you do 7x12 and you get 63 then you do (12x6)/2 and get 27 then you do 63+27 and get 90 (you divide the 12x6 by two because it’s a right triangle)

As he earned $16 for walking his neighbour’s dog four times, we can find out the rate for walking their dog one time by dividing 16 by 4. Therefore, the rate for one walk is $4.

We can then find out how many times Brayden walked his neighbour’s dog when he earned $24 by dividing that by $4.

Therefore, the amount of times he walked his neighbour’s dog is 24/4 which is 6.

15 + -5 = -2x + 3x

15 + -5 = 10

-2x  + 3x = 1x or X

so you answer is:

X = 10

What is the geometric sequences?

Let a be the first term and r be the common ratio. Then the geometric sequences will be

[tex]\rm a_n = a_1} \cdot r^{(n -1 )}[/tex]

Heavy rain in Oxford caused the Brandywine Creek to rise.

The creek rose three inches the first day, and each day twice as much as the previous day.

Then we have

a₁ = 3

r = 2

Then the amount of the creek rise on the fifth day will be

n = 5, Then we have

a₅ = 3 × 2⁽⁵⁻¹⁾

a₅ = 3 × 2⁴

a₅ = 3 × 16

a₅ = 48 inches

The fishermen who, tanned and wrinkled from sun and salt, hauled their nets full of splashing mullet in to cheers from the waiting crowds.
