What are the like terms in the expression below?

Mathematics
1 answer:
natka813 [3]3 years ago
4 0

Answer:

D. -4m, 7m

Step-by-step explanation:

Like terms are terms that can be added, subtracted, divided, and multiplied together. Since -4m and 7m both have the variable m, they are like terms. 3mn is not a like term because it has two variables which makes it different form -4m and 2n. It is its own term.

Find the x- and y-intercept of the line x+4y=36
blagie [28]

Answer:

x=36

y=9

Step-by-step explanation:

Plug in 0 for x to find the y-intercept

0 + 4y = 36

4y = 36

y = 9

y-intercept (0, 9)

Plug in 0 for y to find the x-intercept

x + 4(0) = 36

When a number is decreased by 4%, the result is 93. What is the original number
romanna [79]

Answer:

<u>The original number is 96.875</u>

Step-by-step explanation:

Let's find the original number using the Direct Rule of Three, this way:

       Percentage          Number

              100                       x

               96                       93

***********************************************

96x = 93 * 100

96x = 9,300

x = 9,300/96

x = 96.875

<u>The original number is 96.875</u>

erik [133]

Answer:

The average U.S. citizen throws away about 133.8 pounds of garbage a month.

Step-by-step explanation:

First take the total amount of trash thrown away in a year (1,606), and divide it by the number of months in a year (12).

1,606 / 12 = 133.833333

You would get 133.833333 and would round it to the nearest tenth and get 133.8.

Find the value of c so that the polynomial p is divisible by (x+2)
alexandr1967 [171]

Answer:

The value of c is 8.

Step-by-step explanation:

When a function is divisible by a factor, it will get 0 value. So, you have to substitute x = -2 into p(x) and equals to 0 :

p(x) = 4 {x}^{3}  + c {x}^{2}  + x + 2

p( - 2) = 4 {( - 2)}^{3}  + c {( - 2)}^{2}  + ( - 2) + 2

4( - 8) + 4c - 2 + 2 = 0

- 32 + 4c = 0

4c = 32

c = 32 \div 4

c = 8
