Arrange the given polynomial in descending order. 9x? + 9x +3+2x

1 answer:

7 0

20x+3
This shouldddd be the answer sorry if I’m wrong, but if you group all the x variables together they add up to twenty, then you just add “+3” being that it has no x and therefore must be put in some form of separate group!

Y−5=23(x+4) what is the slope of this equation please

lara [203]

Answer:

The slope of the equation is 23

Step-by-step explanation:

First, we must simplify/solve the equation in order to find the slope

Let's get rid of the parentheses

y - 5 = 23x + 92

Then, combine like terms by moving 5 to the right side of the equation

y - 5 + 5 = 23x + 92 + 5

y = 23x + 97

The slope is always the number that is paired with "x"

If Mary deposits $275 in principal at an interest rate of 3.2 percent, how much interest will she earn in one year

nekit [7.7K]

Answer:

Mary earns interest in one year is $88 .

Step-by-step explanation:

Formula

$Simple\ interest = \frac{Principle\times rate\times time}{100}$

As given

If Mary deposits $275 in principal at an interest rate of 3.2 percent .

Principle = $275

Rate = 3.2%

Time = 1 year

Putting all the values in the formula

$Simple\ interest = \frac{275\times 3.2\times 1}{100}$

$Simple\ interest =\frac{880}{100}$

Simple interest = $88

Therefore the Mary earns interest in one year is $88 .

Determine the solution to the following system of linear equation: y=3x-2 y=-x+6

skad [1K]

Answer:

(2, 4)

Step-by-step explanation:

To solve this system, the easiest way would be to use the substitution method. You can simply plug in, or substitute the value of y from the second equation, which is -x + 6, into the first equation. So you would get:

-x + 6 = 3x - 2

6 = 4x - 2

8 = 4x

2 = x.

To find y, just substitute the value of x, which is 2, into either equation:

y = 3(2) - 2

y = 6 -2

y = 4.

Make sure you write your answer as an ordered pair! So, the final answer is (2, 4). Hope that helped! :)

The time series graph gives some information about the number of

Licemer1 [7]

Answer:

Average is less than 65, therefore, shop did not meet the target.

Step-by-step explanation:

The time series graph gives some information about the number of umbrellas sold in a shop in the first six months of 2015.

From the given graph it is clear that the number of umbrellas sold in Jan, Feb, Mar, Apr, May, June are 54, 84, 72, 94, 52, 26 respectively.

Average sales is

$Average=\dfrac{\text{Sum of number of umbrellas sold in 6 months}}{6}$

$Average=\dfrac{54+84+72+94+52+26}{6}$

$Average=\dfrac{382}{6}$

$Average=63.67$

Since, average is less than 65, therefore, shop did not meet the target.
