Answer:

y = -3x + 8

Step-by-step explanation:

You have to find the slope first using the formula $\frac{y_{2}-y_{1} }{x_{2}-x_{1}}$

Insert any two points in the equation (1,5) and (2,2) and you get -3.

Then, you do any x value times the slope (1*-3 = -3) and add so that it equals the corresponding y value (8).

This makes it y = -3x + 8.

Given that cos 63°≈ 0.454, enter the sine of a complementary angle.<br> sin

jek_recluse [69]

Answer:

$\cos(63^\circ)$ is the same as $\sin(27^\circ)$ by co-function identities

Step-by-step explanation:

Remember that complementary angles add up to 90°. The angle that i s complementary to 63° is 27°.

Also recall the co-function identities:

sin (90° – x) = cos x
cos (90° – x) = sin x

This means that $\cos(90^\circ-27^\circ)=\sin(27^\circ)\approx0.454$ .

Eight friends are going bowling together if they each rent a pair of bowling shoes for $2.00, they each play two

Mnenie [13.5K]

2.00+1.50= 3.50.

3.50x8= 28.00

I'm assuming they each paid 41.00 dollars for two games,

41.00x8= 328.00

328.00+28.00= $356.00

Hope this is correct and/or it helps!

Sorry, didn't realize my mistake.

On Thursday a local shop sold a combination of 417 hamburgers and cheese burgers. The number of cheeseburgers sold was two times

seropon [69]

Answer:

The number of hamburgers sold was 139 and the number of cheeseburgers sold was 278.

Step-by-step explanation:

Let

x -----> the numbers of hamburgers sold on Thursday

y -----> the numbers of cheeseburgers sold on Thursday

we know that

$x+y=417$ ----> equation A

$y=2x$ ----> equation B

Substitute the equation B in equation A and solve for x

$x+2x=417$

$3x=417$

$x=139$

Find the value of y

$y=2(139)=278$

therefore

The number of hamburgers sold was 139 and the number of cheeseburgers sold was 278.
