PLEASE HELP FAST 100 EASY POINTS WILL MARK BRAINLEST!!!
spin [16.1K]

Answer:

y=-1x+8 \\or\\y=-x+8

Step-by-step explanation:

Okay so we know that line on the triangle DEF that's parallel to the line BC is EF. This because they have the same slope and we can prove that while solving for slope-intercept form.

First we figure out our points for both the lines:

BC:  B=(-2,4)   \\C=(1,1)

EF: E=(4,4)\\F=(6,2)

Now that we have our points we can use the slope formula to prove these two line have the same slope and are therefore parallel to eachother:

\frac{y_1-y_2}{x_1-x_2} = Slope Formula

BC = \frac{4-1}{-2-1} =\frac{3}{-3} =\frac{-3}{3} =-1

EF = \frac{4-2}{4-6} =\frac{2}{-2}=\frac{-2}{2}= -1

So now we proved that both of these lines have a slope of -1. Then we can use the slope intercept formula and one of the points from the line EF to find the y-intercept of the of line EF:

Let's use point = (4,4)

y=4,m=-1,x=4,b=?

y=mx+b\\4=-1(4)+b\\4=-4+b\\(+4) 4=-4+b(+4)\\8=b

We used the formula and found that the y-intercept was (0,8), so now we plug in all of our answers:

y=-1x+8

This is the complete answer but if you wanted to simplify it more you could write it as y=-x+8, cause as long as you make the x negative in the equation it will always be as if you multiplied it by -1.

An Angle measures 64 more than the measure of its supplementary angle what is the measure of each angle
ValentinkaMS [17]

Answer:

Original angle = 122*

Supplementary angle = 58*

Step-by-step explanation:

A supplementary angle is one of two angles that make up 180*

If one angle is 30*, its supplementary angle is 150*. 30 + 150 = 180.

So in this case we have two angles, the original and the supplementary angle. The original angle is 64* more than the supplementary angle. The key word is MORE.

The formula to figure it out would look like this:  x + (x + 64) = 180

x is the supplementary angle

x + 64 is the original angle (64 MORE than its supplementary angle)

180 is the total measure of the two angles because they are supplementary and we know that supplementary angles always equals 180* when added together.

Take the formula and do a little algebra.

x + (x + 64) = 180

Subtract 64 from both sides

x + x = 116

Combine the x's

2x = 116

Divide both side by 2

x = 58

Remeber we know that the original angle is 64 more than the supplementary angle, so we'll add the 64 to the value of x and we get 122.

x + 64 = 122

Check our work:

x + (x + 64) = 180

58 + 58 + 64 = 180

Express 4/5 as a decimal using long division
Hoochie [10]

Here, we want to express the given fraction as a decimal by the use of long division

We start by writing the long division sign

We place 5 on the left hand side outside and place 4 inside the long division sign

Now, as we know, 4 cannot divide 5 wholly as it is less than 5

We simply add a 0 at the top of the long division symbol, with a decimal point after it.

Concurrently, we place a zero after 4

Hence we have 40 inside the long division

Then we can divide 40 by 5 to get 8

The 8 now comes after the decimal point

Hence, our answer is 0.8

Pictorally, we can have the representation as follows;
