Solve this system of equations: 3x-2y=2 5x-5y=10
Answer:
(- 2, - 4 )
Step-by-step explanation:
Given the 2 equations
3x - 2y = 2 → (1)
5x - 5y = 10 → (2)
Multiply (1) by 5 and (2) by - 3, then add to eliminate x
15x - 10y = 10 → (3)
- 15x + 15y = - 30 → (4)
Add (3) and (4) term by term to eliminate x , that is
5y = - 20 ( divide both sides by 5 )
y = - 4
Substitute y = - 4 into either of the 2 equations and solve for x
Substituting into (1)
3x - 2(- 4) = 2
3x + 8 = 2 ( subtract 8 from both sides )
3x = - 6 ( divide both sides by 3 )
x = - 2
Solution is (- 2, - 4 )

Answer:
Step 3
Step-by-step explanation:
Given
[tex](5 - 2)^ 2 + 23 * 4[/tex]
Required:
Determine the first step where she made mistake
Her Step 1:
[tex](3)^ 2 + 23 * 4[/tex] --- This is correct because she solved the bracket first
Her Step 2:
[tex]9 + 23 * 4[/tex] --- This is correct because she solved 3^2 as 9
Her Step 3:
[tex]9 + 9 * 4[/tex] --- This is incorrect because 23 * 4 is not equivalent to 9 * 4
Hence, her first mistake is in step 3.
The correct expression would have been
[tex]9 + 92[/tex]
Then
[tex]= 101[/tex]

What are the coordinates of point Q? On a coordinate plane, point Q is 4 units to the right and 2.5 units up. (Negative 4, 2 and one-half) (Negative 2 and one-half, 4) (2 and one-half, 4) (4, 2 and one-half)
Answer:
(4, 2 and one-half)
Step-by-step explanation:
Since, point Q is 4 units to the right and 2.5 units up. Both the coordinates of point Q are positive.
Therefore, Q = (4, 2 and one-half)
The coordinates of point Q will be Q(4, 2.5).
What are coordinates?The coordinates in rectangular cartesian system are of the form -
(x, y)
where -
{x} - distance along x - axis.
{y} - distance along y - axis.
Given is the point Q.
It is given that point Q is 4 units to the right and 2.5 units up. So, the coordinates of point P, will be (4, 2.5).
Therefore, the coordinates of point Q will be Q(4, 2.5).

Explain how to solve systems of linear equations by substitution.
Answer:
Step 1 : First, solve one linear equation for y in terms of x .
Step 2 : Then substitute that expression for y in the other linear equation.
Step 3 : Solve this, and you have the x -coordinate of the intersection.
Step 4 : Then plug in x to either equation to find the corresponding y -coordinate.
Step-by-step explanation:

Answer:
A) y>=-1
Step-by-step explanation:
The line itself is y=-1, but it is also filled in. Therefore, we are down to either A or C as the right answer
Since (0,0) is a solution to the inequality as indicated by the shade, we know that since y=0 in the origin, 0 is greater than -1, so therefore A is the correct answer.

A private university is accepting applications for enrollment. Out of 2,000 applicants, 950 meet the GPA requirements, 600 volunteer for community service, and 250 both meet the GPA requirements and volunteer. Which statement correctly describes the probability that an applicant meets the GPA requirements or volunteers?
The best answer is Because some applicants volunteer and meet the GPA requirements, the events are not mutually exclusive. Thus the probability is 65%.
What is the probability of meeting the GPA requirements or volunteers?The fact that some people could meet both the GPA requirement and the volunteering requirements means that these are not mutually exclusive.
The probability of meeting both would be:
= (Number of people who met either GPA requirements or Volunteer) / Total number of people
= (950 + 600 - 250) / 2,000
= 0.65
= 65%

A pizzeria sells a round pizza with a diameter of 16 inches.
Another pizzeria sells a large square pizza with a side length of 15 inches
Which has more crust along the outside edge of the pizza, the round pizza or the square pizza?
Answer:
Square pizza
Step-by-step explanation:
d = Diameter of round pizza = 16 inches
a = Side length of square = 15 inches
More crust means the edge length of the pizza is greater. Edge length is given by the perimeter.
Circumference or perimeter of the round pizza
[tex]C=\pi d\\\Rightarrow C=\pi\times 16\\\Rightarrow C=50.27\ \text{inches}[/tex]
Perimeter of the square is
[tex]P=4a\\\Rightarrow P=4\times 15\\\Rightarrow P=60\ \text{inches}[/tex]
So, the square pizza has more crust compared to the round pizza.

The kingdom of Arendelle is trying to decide who to send to the regional track meet. Anna, Elsa, and Olaf competed in the long jump and their 6 jumps are shown below (in meters). Kristoff says that Olaf has the longest average, so he should be sent to the track meet. Do you agree or disagree? Why?
Please find table attached
Answer:
Agree: Olaf should be sent to the track meet because he has the longest average
Step-by-step explanation:
To ascertain if this is true, we must calculate the average for each athlete
Mean or average of athlete= total score of jumps/ number of jumps
Average for Anna= 3.25+3.95+4.28+2.95+3.66+3.81/6 = 3.65
Average for Elsa=3.55+3.88+3.61+3.97+3.75+3.59/6
=3.725
Average for Olaf=3.67+3.78+3.92+3.62+3.85+3.73/6
= 3.76
Therefore Olaf has the longest average =3.76
