pleaseee help how do i write an equation in slope-intercept form for the line with slope 1/3 and y-intercept -3?
Montano1993 [528]

Answer:

y=1/3x -3

Step-by-step explanation:

Slope intercept form  is y=mx+b, where m is the <u>slope </u>and b is the <u>y-intercept, </u>or the y-value at which the line intersects the y-axis.

Your slope is 1/3, and your y-int. is -3, so substitute those values in:

y=<u>1/3</u>(x) <u>- 3</u>

Two angles are supplementary. The measure of one angle is 4 times the measure of the other angle. What is the measure of the sma
Alexus [3.1K]
ANSWER

The smaller angle is

y = 36 \degree



.EXPLANATION

Let the angles be
x \:  and \:  \: y

where y is the smaller angle.
Since they are supplementary, they will add up to 180°.


This implies that,

x + y = 180 \degree...(1)


If one angle is 4 times the other, we can then write the following equation,

x = 4y...(2)


We put equation (2) into equation (1) to get,



4y + y = 180 \degree


5y = 180 \degree


We divide through by 5 to obtain,

y = 36 \degree


This implies that,

x = 4(36)


x = 144 \degree

The question is in the image! Please help if u can its due really soon
Leno4ka [110]

Answer:

Angle STR = 78°

Step-by-step explanation:

So, since line QS is a straight line, we know that it's 180°. We also know that angles QTR and STR both add up to 180°. That gives us an equation:

20x + 12 + 10x + 33 = 180

Combine like terms

30x + 45 = 180

Subtract 45 from both sides

30x = 135

Divide both sides by 30

x = 4.5

Now we know the value of x. We just need to plug it into angle STR's given value:

10(4.5) + 33 = angle STR

45 + 33 = angle STR

78° = angle STR
