Answer:
3x+y=13
+2x-y=12
SOlve it like what you would normally do
3x+2x=5x
y+(-y)=0
13+12=25
Basically
5x+0=25
Bring down all appropiate signs
Now solve that
5x=25
x=5
Now to find “y”
Plug in The “x”
3*5=15
15+y=13 now solve that and you’d get -2
If you plug it into the other one, it would be the same thing
2*5=10
10-y=12
-y=2
y= -2
x=5
y= -2

What is the slope of the line through (-7,-2) and (−6,7)?
Answers
Answer:
slope = 9
Step-by-step explanation:
To find the slope of a line that passes through a pair of points, use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of (-7,-2) and (-6,7) into the formula and simplify:
[tex]m = \frac{(7)-(-2)}{(-6)-(-7)} \\m = \frac{7+2}{-6+7} \\m = \frac{9}{1} \\m = 9[/tex]
So, the slope is 9.

Acute triangle
Right triangle
Equilateral triangle
Isosceles triangle
Answers
A triangle with a 90° angle is called a right triangle.
Option B is the correct answer.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
Acute triangle:
The angle is less than 90 degrees.
Right triangle:
The angle is 90 degrees.
Equilateral triangle:
All sides of the triangle are equal.
Isosceles triangle:
Two sides of the triangle are equal.
Thus,
A triangle with a 90° angle is called a right triangle.

A tangent-tangent angle intercepts two arcs that measure 124 degrees and 236 degrees what is the measure of the tangent-tangent angle
Answers
Answer:
It can be calculated by finding the difference between the two angles. Half of this difference will be the angle that is required.
Therefore
236 - 124 = 112
Tanget-tanget angle = 112 / 2 = 56 degrees
Raghav, Rajit, Junsu, Mia, and Umema were finished with lunch and began playing with drink straws. Each one was making a line design using either 3 or 4 straws. Since they had just come from math class where they had been studying special angles, Raghav pulled his pencil out of his bookbag and labeled some of the angles and lines. He then challenged himself and the others to find the values of x and y in degrees.
Show how you would find the values of x and y for Raghav’s straw figure shown below using a system of linear equations. (You may use a decimal to the tenths place for your answers for the angle measures.)
Answers
Answer:
x = [tex]25.8^{o}[/tex] and y = [tex]51.4^{o}[/tex]
Step-by-step explanation:
Known that he sum of angles on a straight line is [tex]180^{o}[/tex]. From the diagram;
2y + x + y = [tex]180^{o}[/tex]
x + 3y = [tex]180^{o}[/tex] ................ 1
Also,
2x + x + 2y = [tex]180^{o}[/tex]
3x + 2y = [tex]180^{o}[/tex] .............. 2
Using the elimination method, multiply equation 1 by 3 and equation 2 by 1
3x + 9y = 540 ............ 3
3x + 2y = [tex]180^{o}[/tex] ............. 4
7y = 360
y = [tex]\frac{360}{7}[/tex]
y = [tex]51.4^{o}[/tex]
substitute the value of y in equation 1,
x + 3y = [tex]180^{o}[/tex]
x + 3(51.4) = [tex]180^{o}[/tex]
x + 154.2 = [tex]180^{o}[/tex]
x = [tex]180^{o}[/tex] - 154.2
x = [tex]25.8^{o}[/tex]
Thus, x = [tex]25.8^{o}[/tex] and y = [tex]51.4^{o}[/tex]

find the value of X such that the data set has a mean of 118. 101, 119, 104, 115, 109, x
Answers
Answer:
160
Step-by-step explanation:
101+119+104+115+109+x=548+x
there are 6 terms including x so divide the sum by 6
(548+x)/6=118
multiply both sides by 6
548+x=708
subtract 548
x=160
hope that helps :)
Answer:
160
Step-by-step explanation:
There are 6 numbers in the set
101 + 119 + 104 + 115 + 109 + x = 6(118)
101 + 119 + 104 + 115 + 109 + x = 708
548 + x = 708
-548 -548
