<u><em>Answer: → =1 *The answer must have a positive sign.*</em></u>

Explanation:

First, you had to do is remove parenthesis.

4-3

And then, subtract by the numbers.  Subtract it's going to be subtract by the numbers, fractions, and find the difference between the numbers.

4-3=1

Hope this helps!

When you are adding a positive and a negative it will always equal a positive. It depends because if the negative number is greater than the positive number than its a negative if u are adding them together. But if the positive number is greater than the negative number and you are adding them together than it will equal a positive. So, or you just switch the addition symbol to a subtraction symbol.


4 + (-3) = 1

Equation:

4 - 3 = 1

which of the following graphs shows a negative linear relationship with a correlation coefficient, r, close to -0.5.
Harrizon [31]

Answer:

In the graph attached there is a sample generated with a correlation coefficient r=-0.5.

Step-by-step explanation:

A value of r that is -0.5 shows that there is a certain correlation and that this correlation is negative.

As there are no examples in this question, I searched for a generator of random samples with a user-input correlation coefficient between the two variables.

In the graph attached there is a sample generated with a correlation coefficient r=-0.5.

Evaluate the expression when a=-15 and b=-5 .<br><br> b+14 <br> ----------<br> 3
brilliants [131]
The answer is 3 because since b=-5 you get -5 and add it to 14 giving you 9 and then you divide 9/3 which gives you 3. Hope this helps :)

1. Sharon and Geordi both worked hard over the summer. Together they eamed a total of $525. Geordi eamed $75
Svet_ta [14]

Answer:

a)

S+G=525

G=S+75

b) See attached pictures

c) S=$225 and G=$300

The point where both graphs meet each other is the point where both equations will be true when having the same S and G values. This is, this is the point where both conditions given by the problem are the same.

Step-by-step explanation:

a) For the first part of the problem, the addition of both amounts will give us the total, so the first equation is:

S+G=525.

On the second equation we need to add 75 to sharon's amount to figure Geordi's amount, so we get:

G=S+75

b) In order to graph the system of equations, we need to find two points for each of the equations. It would be a good idea to solve the first equation for g, so our system of equations would be:

G=525-S

G=S+75

First Equation:

You can pick any value you like for S, for example: S=0 and then substitute it into the equation to get te first G-value:

G=525-0

so G=525.

So the first ordered pair would be (0,525)

You can do the same with a different S-value to get a second point to plot:

S=100

G=525-100

G=424

so the second ordered pair would be (100,424)

and now you can plot the points on the graph and connect them with a straight line.

See attached picture.

Second Equation:

The same procedure is followed for the second equation, in this case I used the same S-values, but you can use different values if you wish, so the two points to plot were:

(0,75)

(100,175)

and the graph looks like the one attached.

c)

In order to figure out how much each person earned, we need to find the point where the two graphs meet each other (see attached picture) in this case the point will be located at (225,300)

This means that Sharon earned a total of $225 while Geordi earned a total of $300.

S=$225 and G=$300

The point where both graphs meet each other is the point where both equations will be true when having the same S and G values. This is, this is the point where both conditions given by the problem are the same.
