Answer:

(2, 72) (5, 180)

Step-by-step explanation:

To solve this, you have to plug in the x values in the ordered pairs into the equation so if it matches.

(2, 72)

y = 36(2)

y = 72

This one checks out.

(4, 40)

y = 36(4)

y = 144

This one does not apply.

(5, 180)

y = 36(5)

y = 180

This one also works.

The second row of answers does not apply because the x value will be less than the y value because you are multiplying the x value.

Tim and Luke start a lawn-mowing business and buy a lawnmower for $325. They plan to charge $25 to mow one lawn. Which inequalit

bonufazy [111]

lawnmower = 325 USD

lawn mowing = 25 / lawn

total profit >= 1000 USD

x = number of lawns

25x - 325 = 1000

25x = 1000 + 325

x = 1325 / 25

x >= 53 lawns

25(53) >= 325 + 1000

The answer is D.

Robert is lying on the ground, looking at the top of a flagpole. The angle of elevation to the top of the flagpole is

NeTakaya

Answer:

Height of flagpole = 571 ft

Step-by-step explanation:

Given:

Angle of elevation to the top of the flagpole is 55° .

Distance from the eyes to the base of flagpole = 400 ft.

To find the height of the flagpole.

Solution:

We can draw the situation as a right triangle as shown below.

In triangle ABC.

$BC=400\ ft$

∠C= 55°

To find the length AB (height of the flagpole).

Applying trigonometric ratio :

$\tan\theta=\frac{Opposite\ side}{Adjacent\ side}$

$\tan C=\frac{AB}{BC}$

Plugging in values.

$\tan 55\°=\frac{AB}{400}$

Multiplying both sides by 400.

$400\tan 55\°=\frac{AB}{400}\times 400$

$571.26=AB$

∴ $AB\approx 571\ ft$

Height of flagpole = 571 ft

5(x - 8) + 15 = 35

Paladinen [302]

Answer:

x=12

Step-by-step explanation:

5(x-8) + 15 = 35

First remove the parenthesis by multiplying

5x-40 + 15 = 35

Add -40+15

5x -25 = 35

Add 25 to both sides

5x=60

Divide both sides by 5

x=12

Now you can plug in 12 for x if you need to, it will equal 35
