Forget about the negative sign. First you have to find a least common denominator. This would be 63. Since we had to multiply 9 by 7 to get 63 we have to multiply the numerator (4) by 7. This gives us a new fraction of 36/63. Since we ha e to multiply 21 by 3 to get 63 we have to multiply 19 by 3. This gives us 57. So now we have 36/63 and 57/63. Then we add the negative sign back in making 57/63 -57/63. Now we add them together. Because one has a negative sign and one is positive the number has to be closer to zero. So the answer is -21/63.

If the graphs of the linear equations in a system are the same line, what does that mean about the possible solution or solutions of the system?

A. There is exactly one solution.
B. There is no solution.
C. There are infinitely many solutions.
D. The lines in a system cannot graph as the same line.

Answers

When the 2 graphs are the same. It'll be infinitely many solutions.

System Equations are to find the intercepts of graphs so just think that when 2 graphs are same, that means they both intercept each others infinitely.

So the answer is clearly C.

what is the slope of (-7,-10) and (-5,-4)

Answers

Answer:

Step-by-step explanation:

6/2=3

Answer:

slope is 3

Step-by-step explanation:

Slope means rise/run

so its y2 - y1

-------------------

x2 - x1

-4 - (-10)

------------

-5 - (-7)

6/2 = 3

I need your help with this!!!

Answers

Answer: y = 2/3x - 9

Method Used:

We will use the point-slope equation to find the slope of this line

We know that according to the point-slope equation:

y = mx + b (where m is the slope and b is the y-intercept of the line)

Now, we will find the slope and the y-intercept of the line in order to find the equation of this line

Finding the Equation:Finding the Slope:

We know that the formula for finding the slope of a line is:

Slope = Rise / Run

We will check the slope between the points, (-9,0) and (-6,2)

We know that rise = y2 - y1 (y of the second - y of the first coordinate)

Rise = 2 - 0 (replacing the values)

Rise = 2

We know that Run = x2 - x2 (x of the second - x of the first coordinate)

Run = -6 - (-9) (replacing the values)

Run = 3

Now that we know the values of Rise and Run, we can find the slope

Slope = Rise / Run

Slope = 2 / 3

Finding the Y-intercept:

We know that the y-intercept of a line is the y-coordinate of the point where the line intersects the y-axis

We can see in the graph that the line intersects the y-axis at the point (0,6)

the y-coordinate of the point (0,6) is 6

Therefore, the line has a y-intercept of 6

Equation of the Line:

We know that the general form for the slope-intercept formula is:

y = mx + b (where m is the slope and b is the y-intercept)

replacing the values of slope and y-intercept

y = (2/3)x + 6

Therefore, the equation of the line in the Graph is y = (2/3)x + 6

Which of the following shows the graph of y = –(2)x – 1?

Answers

Answer:

Graph B

Step-by-step explanation:

Hope I helped!

Graph given option B will be the answer.

This question is incomplete without the options, find the graphs attached.

Parent function for the given expression → [tex]y=2^x[/tex]

If the graph of [tex]y=2^x[/tex] is reflected across x-axis, the new function will be,

[tex]y=-2^x[/tex]

Further the inverted function is translated down by 1 unit on y-axis then the image function will be,

[tex]y=-2^x-1[/tex]

Hence, the graph given in option B will be the answer.

Mr. Kimball sells computer software. He earns a base salary of $41,250 and 8% commission on his sales. Write an equation to represent Mr. Kimball’s total pay p after selling d dollars of software.

Answers

Answer:

P=0.08d+41,250

Step-by-step explanation:

The total amount earned, p which is the sum of the base salary and the commision on sale can be expressed as ;

p = 41250 + 0.08d

Given the Parameters :

Base salary = 41250Commission percentage = 8% = 0.08Amount of sales made = d

The total pay after selling software worth $d can be expressed thus :

Base salary + (commission percentage × amount of sales)

Total pay = 41250 + (0.08 × d)

p = 41250 + 0.08d

Therefore, the total pay, p is expressed as 41250 + 0.08d

Step-by-step explanation:

Given

y = 9 - 4x

Substitute the given values of x into the equation and evaluate for y

x = - 2, then

y = 9 - 4(- 2) = 9 + 8 = 17 ⇒ (- 2, 17 ) ← ordered pair

x = 5, then

y = 9 - 4(5) = 9 - 20 = - 11 ⇒ (5, - 11 ) ← ordered pair
