Answer: A: (6, 5)
Step-by-step explanation:
When graphing a system of equations, you can find the solution by finding where the graphs intersect. In this case, the graphs intersect at (6, 5).
To verify that this is indeed a solution to the system of equations, we can substitute (6, 5) into both of the given equations:
[tex]y = \frac{1}{2}x + 2[/tex]
[tex]5 = \frac{1}{2} * 6 + 2[/tex]
[tex]5 = 3 + 2[/tex]
[tex]5 = 5[/tex]
[tex]y = x - 1[/tex]
[tex]5 = 6 - 1[/tex]
[tex]5 = 5[/tex]
Since both equations hold true when plugging in the given coordinate (6, 5), we know that this is a solution to the system of equations.

Step-by-step explanation:
equilateral triangles are also equiangular which means each of the three angles is 60°
but you can have an acute triangle with angle measures that are all acute (for example, 59°, 85°, and 36°) that is not equilateral
E = {10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23}
A = {odd numbers}
B = {multiples of 3}
Complete the Venn diagram for this information.

A
B
e
15,2
Answer:
A=11,13,17,19 B=12,18 None=10,14,16,19 Both=15
Step-by-step explanation:
11,13,15,17,19 are all odd so they go in A
12,15,18 Are all multiples of 3 so they go in B
10,14,16,19 Are not classified so they go outside of the diagram but inside E
15 is odd and a multiple of 3 so put it in the center and not with A and B
Triangle PQR is shown. The triangle has a base of 4 in and a height a 2.5 in.
Which measurement is closest to the area of triangle PQR in square inches?
5 in2.
8 3/4in.2
6 1/2in.2
11in.2
Answer:
A
Step-by-step explanation:
Area = 1/2 * b * h
b = 4 in
h = 2.5 inches
Area = 1/2 * 4 * 2.5
Area = 2 * 2.5
Area = 5 in^2
A large factory that builds machines has three shifts, one that starts at 4:00 A.M., one that starts at noon, and one that starts at 8:00 P.M. The manager of the factory wanted to know whether there is an association between an employee’s work experience (less than five years with the company, between five and twenty years with the company, over twenty years with the company) and the time of the employee’s shift. The manager selected a random sample of 125 employees and classified employees by their shift time and work experience. What is an appropriate pair of hypotheses for the manager to use?
Answer:
if the worker has more experience, then they will have longer shifts because they will be better at their job and be able to complete more tasks.
Step-by-step explanation:
use and "if then because" structure in a hypothesis, and use common logic based on the info provided :)
Answer:
[tex]H_{0}[/tex] : Work experience is independent of the time of an employee's shift
[tex]H_{A}[/tex] : Work experience is dependent on the time of an employee's shift
Step-by-step explanation:
Since we have one population but multiple variables, so we are using a chi-square test of independence. Thus, our null should be that there is no association, and the alternative that there IS an association.

9. Find the value of
the expression.
16 + 4 + (42 - 3) =
Answer:
59Step-by-step explanation:
16 + 4 + (42 - 3) = 20 + 39 =59Answer:
59
Step-by-step explanation:
16 + 4 + (42-3) = 59. Do parentheses first. (42-3) = 39. Which changes the equation to 16 + 4 + (39). 39 + 4 = 43. Then the equation changes to 16 + 43. These added together equal 59. Hope this helps!
PEMDAS= Parentheses, exponents, multiplication, division, addition, and then subtraction.
This is the order in which to solve these types of equations, which is why I did the parentheses first.

what is the scale factor of the small triangle to the large triangle?
Answer:
I'm pretty sure it's 4.3?
Step-by-step explanation:
Because you divide the larger triangles side first because you are figuring out the scale factor of the small triangle to the larger triangle, not the other way around.
Sorry if i'm wrong
Answer:
first, find the area of the small triangle: 3 times 3 equals 9 divided by 2 equals 4.5.
second, find the area of the big triangle: 13 times 13 equals 169 divided by 2 equals 84.5.
Find difference: 84.5 minus 4.5 equals 80

For which equation is b = 5 not the solution?
options:
1. 8 - b = 13
2. b + 6 = 11
3. b + 4 = 9
4. 12 - b = 7
Answer:
option 2 and 3
b+6=11
b+4=9
Answer:
1. 8 - b = 13
Step-by-step explanation:
It says for which equation is b = 5 not the solution.
So, we need to plug in 5 into every b, and find out which one is incorrect.
1. 8 - 5 = 13 (incorrect)
2. 5 + 6 (correct)
3. 5 + 4 = 9 (correct)
4. 12 - 5 = 7 (correct)
Therefore, option 1 is the answer to your question.

Answer:
12
Step-by-step explanation:
Since the entire line is 60 and MN is five times as long. Then I would say that you could just divide 60 by 1/5 or 0.2
since the length of the line is 60 you gots to fos and divide it my homie.
60/5=12 so thats means the length is 12
you got that my guy

0600 square centimeters
O 300 square centimeters
O 150 square centimeters
160 square centimeters
Answer:
150 square centimeters
Step-by-step explanation:
Area of a triangle:
The area of a triangle is the multiplication of 0.5, the base length and the height length.
What is the area of a triangle having a height of 20 centimeters and a base length of 15 centimeters?
[tex]A = 0.5*20*15 = 10*15 = 150[/tex]
The area of the triangle is 150 square centimeters.
