3. 5x-2
4. -3x+15
5. -4x-28
6. -4x+ 12
7. 8x+ 40
To find the answer you need to multiply the number outside of the parentheses by each number/variable in the parentheses.
For example, number 9 says 8(-x-6) you would have to "distribute" the 8 out the both the variable and the number.
8 multiplied by -x is -8x because a negative times a positive is a negative and 8 multiplied by -6 is -48. So there for your answer would be -8x-48

You have to make sure to also remember the multiplying rules:
positive times a positive= positive
positive times a negative= negative
negative times a negative= positive
( i hope this helped! i don't do all of them bc there is quite a lot but yeah!)

Answer:

v= 13

w= -32

Step-by-step explanation:

2v+6w=-36

5v+2w=1

2w= 1-5v

2v+ (3)(1-5v)= -36

2v+3-15v= -36

3-13v =-36

3--36= 13v

39= 13v

13 = V

5×13+2w=1

65+2w=1

1-65= 2w

-64=2w

-32=w

When the p-value is used for hypothesis testing, the null hypothesis is rejected if _____
pashok25 [27]

Answer:

B

Step-by-step explanation:

Here, we are to give the reason why we would reject the null hypothesis during the hypothesis testing.

In considering whether to accept the null hypothesis or reject the null hypothesis, we have to take into consideration two things.

The p-value and the alpha value. The p-value refers to the probability which is directly obtainable from the standard score which is referred to as the z-score while the alpha refers to the level of significance.

Now, when the p-value is less than alpha, we simply reject the null hypothesis and accept the alternative hypothesis. In a case however, we have the value of p greater than or equal to the significance level alpha, we simply accept the null hypothesis in this case.

The question asks for a rejection case and this can happen only when the p-value is less than the level of significance alpha

Refer to the equation 2x − 6y = 12 Create a table of values for at least 4 points. Show your work
natka813 [3]

Answer: The table and figure are given below,

Solution:

The given equation is 2x-6y=12.

put x=0 in the equation.

2(0)-6y=12

-6y=12

y=-2

Similarly find the values of y at different values of x. The values are shown in the table.

From table it is notices that the value of y=-2 for x=0, y=-1 for x=3, y==-3 for x=-3, y=0 for x=6.

Plot these points in the coordinate plane and joint them by a straight line.

The gra his shown in below figure.
