Answer:

(3 {y}^{5}  - 2y + 8) + (2 {y}^{5}  -  {4y}^{3}  - 7) \\  = 5 {y}^{5}  - 4 {y}^{3}  - 2y + 1

Find the y and x intercept 6x-8y=48
Crank

6x-8y=48


to find the x intercept  set y=0

6x - 8*0 = 48

6x = 48

divide by 6 on each side

x =48/6

x=8

 (8,0)


to find the y intercept  set x=0

6(0) - 8y = 48

0 - 8y = 48

-8y = 48

divide by -8 on each side

y = -6

(0,-8)

Kelsey had $65 to spend on books. Each book cost $5.50, and there was a $7.50 fee for shipping. She let b equal the number of bo
GuDViN [60]

Answer:

Let the number of books she can purchase = b

The cost of each book is $5.5 with an extra shipping of $7.5

So, the total cost of the books she can purchase = 5.5b+7.5

Since, she had $65 to spend on the books.

The required inequality is 5.5b+7.5\leq 65.

So, according to the inequality above, we get,

The correct options are,

B. The inequality symbol is incorrect because she can spend up to and including $65.

C. The expression  5.5b+7.5 is correct because $5.50 per book is  5.5b and that is added to the shipping fee of $7.50 to determine the total purchase price.

Find the measure of angle 1 given the following: angle 3 and angle 4 are complementary (angles add up to 90 degrees), angle 2 is
aleksandrvk [35]
When you add up all the angles, it would be equal to 180 degrees.

Since angles 2 and 3 are congruent, angle 3 is also equal to 6x + 24.
We know also that angles 3 and 4 are complementary, so (6x+24) + 5x = 90. 

Let's find x. 
6x+24+5x = 90
11x = 90-24
11x = 66
x = 6


Angle 2 and 3 are 6(6) + 24 = 60 degrees
Angle 4 is 5(6) = 30 degrees 

180 - 60 - 60 - 30 = 30 degrees

Angle 1 is equal to 30 degrees :D :D

If the endpoint is (-2,-6) and the midpoint is (8,-1) then what is the other endpoint
olga_2 [115]

Answer:

(25,-26)

Step-by-step explanation:

difference between the two points in x and y coordinates are

x = 10 - (-5) =15, y = -9 - 8 = -17,

so to get to the other endpoint you need to add another

x = 15 and y = -17 to the midpoint, (10,-9).

10+15 = 25 for x and -9 - 17 is -26 for y.
