Original Equation.

5(2x - 8) + 15 = -15

First do what is in the parenthesis.

2 x 1 = 2

2 - 8 = -6

5(-6) + 15 = -15

Multiply 5 x -6 to get -30

-30 + 15 = -15

add 15 + -30 to get -15

-15

x = 1

Hope This Helps!

X is 1.

first, you distribute the 5 into the parentheses.
 5(2x-8)+15=-15 becomes 10x-40+15=-15

then you calculate the sum
10x-40+15=-15 becomes 10x-25=-15

after that you move the constant to the right of the equal sign and change the sign (ex negative becomes positive number)
10x-25=-15 becomes 10x=-15+25

next, you add the constants
10x=-15+25 becomes 10x=10

lastly, you divide the numbers.
10x=10 becomes 1

so x=1

Many non-profit groups ask for donations during December. Do men give higher monetary donations than women in the month of Decem
Lelu [443]

Answer:

For this case we want to test if do men give higher monetary donations than women in the month of December (alternative hypothesis) and the complement should be the null hypothesis. So then the sytem of hypothesis are:

Null hypothesis:\mu_m -\mu_w \leq 0

Alternative hypothesis : \mu_m -\mu_w >0

So then the best option would be:

d. Ha: mum -muw > 0

Step-by-step explanation:

Previous concepts

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".  

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".  

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".  

Solution to the problem

For this case we want to test if do men give higher monetary donations than women in the month of December (alternative hypothesis) and the complement should be the null hypothesis. So then the sytem of hypothesis are:

Null hypothesis:\mu_m -\mu_w \leq 0

Alternative hypothesis : \mu_m -\mu_w >0

So then the best option would be:

d. Ha: mum -muw > 0

I need these graphed, they’re easy but I don’t have time to do them since it’s late. Excuse the bad handwriting
Nata [24]

Answer:

For #5 all you have to do is set down to points in order for it to count. The answer is: (0,2) and (3,6)

Step-by-step explanation:

In order to find where exactly you must plot the points, we plug in what we know. In our equation, the 2 is our y intercept, this means that the point is (0,2) (Side Note: here's another example, (0,6) the 6 would be our y intercept)

From the point (0,2) we use the other value given. The other value given in this case, is our slope. When dealing with slope, we use Rise over Run or Rise/Run. This means that from the 2 on the graph, you rise 3 which would be 5 and you run to the right for 4. This now gets you the points (3,6)

Hope this helps with plotting the other questions! :)

(SIDE NOTE: IF THEY GIVE THE VALUE WITH X AS JUST A NUMBER, YOU CAN PLACE A 1 UNDER IT TO TURN IT INTO A FRACTION. FOR EXAMPLE 3X CAN BE TURNED INTO 3/1 WHICH WOULD THEN BE RISE 3 AND RUN 1.

(sooory about the caps, it's just to get your attention.)

_a and .bare complementary angles. Za measures 59"<br> What is the measure of b?
sergeinik [125]

Answer:

Step-by-step explanation:

When two angles add up to 90, they are complementary angles

∠a + ∠b = 90

59 + ∠b = 90

∠b = 90 - 59

∠b = 31°
