Answer:

The x-intercept is 2.

The y-intercept is 5.

Step-by-step explanation:

The x-intercept is basically finding what the value of x when y is 0; y-intercept is vise-versa.

The format it is currently in is not in y=mx+b form which makes you unable to put on a graph...HOWEVER, YOU ACTUALLY CAN!

You goal for these type of questions is to isolate y by itself.

-20x+8y=40\\8y=20x+40\\y=2.5x+5

Your equation has been converted into y=mx+b which now can be used to easily find the x and y intercepts.

<u>You can either look at a graph and find the x and y intercepts or do it algebraically. </u>

Since, "<em>x-intercept is basically finding what the value of x when y is 0</em>", we plug in y with 0.

<u>Solve for X-Intercept: </u>

0=2.5x+5\\-5=2.5x\\-2=x

X-Intercept is -2

<u>Solve for Y-intercept:</u>

y=2.5(0)+5\\y=5

Y-Intercept is 5

Which inequality is graphed on the number line? please Hurry!!!
user100 [1]

Answer:

Option C

Step-by-step explanation:

From the number line given in the picture,

Blue arrow has the starting point at a = 6 (Dark point) and moving towards negative side of the number line.

Therefore, number line represents a ≤ 6

3a ≤ 3(6)

3a ≤ 18

3a - 11 ≤ 18 - 11

3a - 11 ≤ 7

Therefore, Option C is the correct option.

What is the slope of a line that passes through the points (-5,-3) and (9,-6)
kipiarov [429]
To find the slope given two points, you need to subtract the two y values over the two x values
(-5,-3)  (9,-6)
-5 will be x1, and -3 will be y1. 9 will be x2, and -6 will be y2. You then need to put the numbers in the correct place in the equation.
y2-y1      -6-(-3)     -9
-------- =   -------- =  ----
x2-x1       9-(-5)     14
Now that we have the slope (-9/14) you can use one of the coordinates to find the value of b.
Let's use (9,-6).
-6=-9/14(9)+b
-6=-81/14+b
+81/14
b=-3/14
Your final equation is y=-9/15x-3/14

In the figure, and bisect each other. Complete the statements to prove that quadrilateral ABCD is a parallelogram.
Alisiya [41]

Observe the figure below.

    Statement                                                                          Reason

1. AC and BD bisect each other                                             Given

2. AE = EC and BE = ED                                                         Definition of bisection

3. m \angle AEB = m \angle CED                       Vertical angle theorem

Vertical angle theorem states " When two lines intersect each other, the vertically opposite angles are always equal".

4. \Delta ABE \cong \Delta CDE                         SAS criterion for congruence

5. m \angle ACD = m \angle CAB           Corresponding angles of congruent triangles are congruent

6. AB \parallel CD                                 Converse of alternate interior angle theorem

7.  m \angle BEC = m \angle AED                   Vertical angle theorem

8.  \Delta BEC \cong \Delta DEA            SAS criterion for congruence

9.  BC \parallel AD                                 Converse of alternate interior angle theorem

As, \Delta BEC \cong \Delta DEA, so m \angle CBD = m \angle BDA as corresponding parts of corresponding triangles are equal. As these angles are alternate interior angles, so the lines BC and AD are parallel by  "Converse of alternate interior angle theorem".
