Mathematics

Answer:

Step-by-step explanation:

The equation can be rearranged to slope intercept form of

y = 4x - 2

We know that the y-intercept is -2 because it is the leftover part, and the slope is 4 because it is 4x.

You can plug in an x-value from the table into the equation, and if it is correct, all the values should end up with the same and correct y-value.

-5 times 4 is -20

-20 -2 = -22.

Correct so far

0 times 4 is 0.

0 - 2 = -2.

Correct so far.

3 times 4 is 12.

12 - 2 = 10.

Correct!

Checking B:

-22 times 4 = -88.

-88 - 2 = -90.

Wrong.

Checking C:

-5 times 4 = -20.

-20 - 2 = -22.

Wrong.

It must be A

What is the reference angle for 295 degrees?

Kay [80]

A reference angle is always between 0-90. so 360-295=65deg.
Hints: 
Quadrant I angle: reference angle is same as given angle. 
Quad II: subtract angle from 180 
Quadrant III: subtract 180 from angle 
Quad IV: subtract angle from 360.

Find x Plz help me !!!

mel-nik [20]

Answer:

$\Huge\boxed{x=33.2}$

Step-by-step explanation:

Hello there!

We can solve for x using law of sines

As we can see in the image a side length divided by sin ( its opposite angle) = a different side length divided by sin ( its opposite angle)

So we can use this equation to solve for x

$\frac{21}{sin(35)} =\frac{x}{sin(65)}$

Our objective is to isolate the variable using inverse operations so to get rid of sin (65) we multiply each side by sin (65)

$\frac{x}{sin(65)} sin(65)=x\\\\\frac{21}{sin(35)} sin(65)=\frac{21sin(65)}{sin(35)}$

we're left with

$x=\frac{21sin(65)}{sin(35)}\\x=33.18208755$

assuming we have to round the answer would be 33.18 or 33.2

Estimate 76.216+66.36 by first rounding each number to the nearest whole number.

xeze [42]

Answer:

142

Step-by-step explanation:

Round the numbers to their nearest WHOLE NUMBER.

$76.216=76\\66.36=66$

Then ADD

$76+66=142$
