Step-by-step explanation:

(1) x+10y=20, x=20,y=2

(2) 6x+y=-18, x=-3,y=-18

(3) 2x-9y=-36, x=-18,y=4

(4) x=-6,y=-15

(5) x=9,y=12

(6) x=-18,y=-3

(7) x=16,y=-6

(8) x=14,y=8

(9) x=-12,y=9

(10) x=-15,y=-6

(11) x=12,y=10

Rule Example

+(+) Two like signs become a positive sign 3+(+2) = 3 + 2 = 5

−(−) 6−(−3) = 6 + 3 = 9

+(−) Two unlike signs become a negative sign 7+(−2) = 7 − 2 = 5

−(+) 8−(+2) = 8 − 2 = 6

Choose the model that represents the function

kirill [66]

Answer:

OPTION D

Step-by-step explanation:

We have to determine which option determines the function given above.

To determine the function, just substitute the values and compare LHS and RHS.

we have $f(4) = 18$

$f(-2) = -12$

$f(0) = -2$

$f(-3) = -17$

Here, $x$ is the domain and $f(x)$ is the co-doamin.

Therefore, $x = \{4, -2, 0, -3\}$

Now, OPTION A: $f(x) = 2x - 5$

Substitute x = 4. We get f(x) = 3 $\ne$ 18.

So, OPTION A is rejected.

Similarly, OPTION B: $f(x) = 5x + 2$

Substitute x = 4. We get f(4) = 22 $\ne$ 18.

It is rejected as well.

Now, for OPTION C: $f(x) = \frac{x}{2} - 5$

Substitute x = 4. We get f(4) = -3 $\ne$ 18.

So, OPTION C is also rejected.

OPTION D: $f(x) = 5x - 2$

Substitute x = 4. We get f(4) = 18.

Substitute the remaining points in domain as well. We notice that it exactly matches the given function. So, OPTION D is the answer.

In a certain year, the population of Smallburg was 4,000. In the following year, the population increased by 15%. What was the r

kupik [55]

Answer:4600

Step-by-step explanation:

15% of 4000

15/100 x 4000

(15x4000) ➗ 100

60000 ➗ 100=600

4000+15% of 4000

4000+600=4600

Brandon is making a ramp . The ramp stands 3 feet tall and is 9 feet long . How long is the base of the ramp

tresset_1 [31]

Answer: 8.48 Feet

Step-by-step explanation:

We can use the Pythagorean Theorem, A^2 + B^2 = C^2

A^2 + B^2 = C^2

A^2 + 3^2 = 9^2

A^2 + 9 = 81

81 - 9 = A^2

72 = A^2

√72 = A

8.48 = A

Hope this helps!

Select all the distribution shapes for which it is most often appropriate to use the mean .

goblinko [34]

The distribution shape that tells us for which it is best to use the mean is the skewed.

This is the term that is used to refer to the average score that exists in a data set.

In the question, these are the reasons why the other options are not correct

When we say Bimodal we are talking about the 2 modes that are in a symmetric distribution. This has nothing to do with the mean

The bell shape has to do with how the normal distribution is when it is drawn. It would create a bell shape hence the mean is not useful.

symmetric has to do with the fact that there are mirror images when the vertical line is drawn in the distribution.

Uniformed shapes tells us that the classes are made up of the same frequency all through.

The skewed shape is what tells us if the median is more or if it is less.

Hence we have the answer that the distribution shapes for which it is most often appropriate to use the mean is the skewed.
