No, it is actually $x^6$ .
When multiplying two equal numbers that have different exponents, just add the exponents.

> Last year the ratio of the number of middle school students
> to the number of high school students was 1:8.
1/9 x + 8/9 x = makeup of middle and high school students

> this year the ratio ... changed to 2:7
2/9 x + 7/9 x = x (again)

> there are 18 middle school students in the band this year
2/9 x = 18
2x = 9 * 18 → x = 81

Total = 81 in band ...
Last year:
1/9 and 8/9 = 9 and 72
This year
2/9 and 7/9 = 18 and 63

And from there you can figure out the changes:
+9 for middle school (which is increase from 1/9 to 2/9)
--9 for high school (which is decrease from 8/9 to 7/9)

podryga [215]

Answer:

$6x+2$

Step-by-step explanation:

<u><em>The complete question is</em></u>

Jaden and Joel both worked at the coffee shop today. Jaden's total cups of coffee made is represented by f(x), and Joel's total cups of coffee made is represented by g(x). Use the functions below to write a function that represents the total cups of coffee they made today.

f(x) = 4x − 1

g(x) = 2x + 3

Options

6x + 2

2x + 1

2x − 4

4x + 4

we know that

To find out the total cups of coffee they made today, sum Jaden's total cups of coffee plus Joe's total cups of coffee

f(x)+g(x)

substitute the values

$(4x-1)+( 2x + 3)$

Group terms

$(4x+2x)+( 3-1)$

Combine like terms

$6x+2$

(p^3 - 56p + 57) ÷ (p + 8) using synthethic division

pav-90 [236]

We need to perform division given the following expression:

p² - 8p + 8
-------------------------------
(p+8) √ (p³ + 0p² -56p +57)
- (p³ + 8p²)
----------------------------
0p³ - 8p² -56p + 57
- (-8p - 64p)
--------------------------
0p² + 8p + 57
- (8p + 64)
--------------------------
0 - 7

The answer is p²-8p+8 + (-7/p³-56p+57).

Solve the system by graphing.

olya-2409 [2.1K]

Option A: (0,2) is the correct answer

Step-by-step explanation:

the given equations are linear equation.

System of linear equations can be solved by graphing. The graph of equations are in the form of lines, the solution of the equations is the point of intersection of both lines

Given equations are:

$y = x+2\\y = -2x+2$

We have used the online graphing calculator "desmos" to plot the lines (Picture Attached)

The lines intersect at: (0,2)

Hence,

Option A: (0,2) is the correct answer
