how to tell if a graph is a function?

Answers

Answer 1
Look at one of the graphs you have a question about. Then take a vertical line and place it on the graph. If the graph is a function, then no matter where on the graph you place the vertical line, the graph should only cross the vertical line once.
Answer 2

Answer:

If you take a vertical line and place it on the graph, then no matter where on the graph you place the vertical line, the graph should only cross the vertical line once. If so, then it is a vertical line.

If not, then it isn't one.

If ABCD is a rectangle, BD = 2x + 5 and AC = 7x - 40. Find the value of BE.

Answers

Answer:

AC = 23

BD = 23

Step-by-step explanation:

ABCD is a rectangle,

AC and BD are its diagonals.

Diagonals of a rectangle are congruent.

Therefore,

AC = BD

7x - 40 = 2x + 5

7x - 2x = 5 + 40

5x = 45

x = 45/5

x = 9

BD = 2x + 5 = 2*9 + 5 = 18 + 5 = 23

AC = 7x - 40 = 7*9 - 40 = 63 - 40 = 23

Can someone help please, i really get confused with equations, please step by step explanation

Answers

Answer: PR equals 6x-2 and x=6.

Step-by-step explanation: Try drawing a diagram to better visualize this, add both the equations, (2x+5)+(4x-7). Be careful of the negative, distribute properly. You should get 2x+5+4x-7 which becomes 6x-2. And finally since they have a midpoint between, both equations are equal to each other. So 2x+5=4x-7. Which should give you x=6.

8. Two streets intersect at a traffic light, forming vertical angles. If the
measure of one of the angles formed by the intersecting streets is 78°,
what are the measures of the other three angles? Draw and label a
picture of the scenario. Show your work for how you found the missing
angles. (3 points)

Answers

The measures of the angles in the intersection are 78 degrees, 78 degrees, 102 degrees and 102 degrees

How to determine the measure of the three variables?

The measure of one of the angles is given as 78 degrees

Represent this angle with x

So, we have

x = 78

Vertical angles are congruent angles

This means that

Vertical angle =  x = 78

The other angles adjacent these angles are also congruent

And the measure of these angles is calculated using

y + x = 180

Substitute the known values in the above equation

So, we have

y + 78 = 180

Subtract 78 from both sides of the equation

So, we have

y + 78 - 78 = 180 - 78

Evaluate the like terms in the above equation

So, we have

y = 102

This means that the measure of the other angles is 102 degrees

Hence, the measures of the angles in the intersection are 78 degrees, 78 degrees, 102 degrees and 102 degrees

if akayla painted 1/3 of a wall in 20 minutes how long will it take her to paint 4 walls

Answers

Answer:

240 minute or 4 hours

Step-by-step explanation:

We can use a ratio to solve

1/3 wall           4 walls

-------------  = ----------------

20 minutes      x minutes

Using cross products

1/3 x = 20 *4

1/3 x = 80

Multiple each side by 3

1/3 x* 3 = 80*3

x = 240 minutes

Divide each side by 60 to change to hours

x = 240/60

x = 4 hours

9. If two complementary angles are in the

bigger angle.​

Answers

Answer:

idk

Step-by-step explanation:

Complementary angles are pair angles with the sum of 90 degrees. We have Two complementary angles are in the  ratio 3:7:

α = 3k

β = 7k

Then:

3k + 7k = 90°

10k = 90

k = 90/10

k = 9

The bigger angle is:

β = 7(9) = 63°

Two Angles are Supplementary when they add up to 180 degrees.  Then the supplementary angle for β is:

x = 180 - 63°
