A.

4x+10=6x
-4x. -4x
——————-
10=2x
— —
2x 2x
= 5. The 2xs cancel out
* the sum of 2 angles =90 degrees


B

5x+13 = 3x+7
Subtract 3x on both sides ( always the less amount gets subtracted )
5x-3x =2x +13
3x-3x cancels out so you get +7
Now you have the equation 2x+13=7
-13 - 13
Subtract 13 to both sides ( opposite )
2x = 6
Divide by 2 and your answer is 6.

GEOMETRY. 20 POINTS. PLEASE DO NOT GIVE STUPID ANSWERS.

Hey there!

A quadrilateral has 360 degrees. So add all the degrees together to 360. 9x+1+5x-12+8x+61+90=360. 90 degrees is in the bottom left corner. Combine like terms. 22x+140=360. Subtract 140 from each side. 22x=220. Divide 22 on each side to get x=10. Plug in 10 for x in angle D. 5(10)-12=38. The measure of angle D is 38 degrees.

I hope this helps!

HELP <br><br>Determine whether the relation is a function<br><br> y=2w=2​
nexus9112 [7]

Answer:

Hi there!

I might be able to help you!

It is NOT a function.

<u>Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function</u>. <u>X = y2 would be a sideways parabola and therefore not a function.</u> Good test for function: Vertical Line test. If a vertical line passes through two points on the graph of a relation, it is <em>not </em>a function. A relation which is not a function. The x-intercept of a function is calculated by substituting the value of f(x) as zero. Similarly, the y-intercept of a function is calculated by substituting the value of x as zero. The slope of a linear function is calculated by rearranging the equation to its general form, f(x) = mx + c; where m is the slope.

A relation that is not a function

As we can see duplication in X-values with different y-values, then this relation is not a function.

A relation that is a function

As every value of X is different and is associated with only one value of y, this relation is a function.

Step-by-step explanation:

It's up there!

God bless you!

A gardener wishes to plant plants in such a way that each row contains as many plants as the number of rows. He has 2624 plants.
vagabundo [1.1K]

Answer:

80

Step-by-step explanation:

we search for a square number so that rows*plantsInARow gives us the number

The number should be around 50², guessed

50² = 2500 (to low)

51² = 2601 (still to low)

52² = 2704 (bingo)

now to get from 2624 to 2704 plants he needs 80 more. That is the least number.

He could also go to plant 60² plants an than need slot more.

(would really appreciate the brainliest)

astraxan [27]

Answer:

The median are equal

Step-by-step explanation:

Given

I will answer this question with the attached plot (see attachment 2)

Required

The equal statistical measures

See attachment 1 on how to read a box plot

Using attachment 1 as a guide, we have the following observation

<u>Movie 2</u>                                                   <u>Movie 1</u>

Minimum=7.5                                      Minimum=10

Q_1 = 22.5                                                 Q_1 = 15

                                  Median = 30

Q_3 = 35                                                   Q_3 = 40

Maximum = 47.5                                    Maximum = 52.5

By comparison, they have equal median (30)
