A. 1/243
B. –15
C. 1/729
D. –125

Answers

Answer:

A. 1/243

Step-by-step explanation:

f(x) = 3^x

f(-5) = 3^-5

We know a^-b = 1/a^b

f(-5) = 1/3^5

      = 1/243

JM = JK/2

3X + 15 = 11X/2 + 20

×2 TO THE ALL OF THE EQUATION

6X + 30 = 11X + 40

6X - 11X = 10

In the attachment below I need you to find m∠DBC.

Answers

Answer:

m<DBC = 109

Step-by-step explanation:

8x-27=6x+7

8x=6x+34

2x=34

x=17

8(17)-27= 109

Answer: 109

Step-by-step explanation:

i'm not entirely sure of this answer as its been a while since ive done problems like this, however, i think the steps to solve are setting (8x-27) equal to (6x+7). Once you do that, you can solve for x. Substitute x into angle DBC to find the answer.

Angel got a job at in-n-out burger. He works 20 hours a week and makes $15.75 an hour. How much will his
paycheck be after 2 weeks of work (before uncle sam takes away taxes

Answers

Multiply hours per week by hourly pay rate:

20 x $15.75 = $315.00 per week

Multiply by 2 weeks:

$315 x 2 = $630

After 2 weeks paycheck is $630

Answer:

630

Step-by-step explanation:

15.75 x 20 = 315

315 is how much Angel makes in one week

315 x 2 = 630

630 is how much he will make in two weeks

The 2 signifies how many weeks have been worked

Solve the system using the elimination method.

2x + 2y + 5z =−1

2x − y + z =2

2x + 4y − 3z =14

What x,y, and z?​

Answers

Answer:

x=151/64   y=9/8 z=-51/32

Step-by-step explanation:

2x+2y+5z- (2x-y+z)=-1-2

3y+4z=-3

2x+2y+5z- (2x+4y-3z)=-1-14

-2y+8z=-15

We have two equations 3y+4z=-3 and -2y+8z=-15 (We get it due to elimination method)

3y+4z=-3 (2)

-2y+8z=-15 (-3)

6y+8z=-6

6y-24z=45

(6y+8z)- (6y-24z)= -6-45

32z=-51

z=-51/32

3y-204/32=-3

3y= -96/32+204/32

3y=108/32

y=36/32=9/8

2x+2*9/8+5*(-51/32)=-1

2x+9/4-255/32=-1

2x+72/32-255/32=-1

2x-183/32=-32/32

“Average rate of change” is the fancy way to say “slope.”

Sketch a graph and put two points with the same y-value, say (2,5) and (7,5).

How much rise is there between those two points? Since they have the same y-value there is no rise at all. You have a horizontal line.

The slope of a horizontal line is 0.
