Question 1) Use the linear combination method to solve the system of equations. Explain each step of your solution. 2x - 3y = 13, x + 2y = -4. ( I'll post a picture of the question and problem incase there's any confusion). Will Mark Brainliest.
Answers
Answer:
x = 2 and y = -3
Step-by-step explanation:
The given equations are:
2x - 3y = 13 ...(1)
x + 2y = -4 ...(2)
Multiply equation (2) by 2.
2x + 4y = -8 ...(3)
Subtract equation (3) from (1).
2x - 3y-(2x + 4y) = 13-(-8)
2x-3y-2x-4y = 13+8
-7y = 21
y = -3
Put the value of y in equation (2).
x + 2(-3) = -4
x-6=-4
x = 6-4
x = 2
So, the solution of the given equations are x = 2 and y = -3.

∠BCA and ∠DCE are equal because they are vertically opposite angles. Segment AC = segment CE because the bisector BD divides the segment AE into two equal parts which are segment AC and segment CE.segment BC and segment CD will be equal because bisector AE divides the segment BD into two equal parts which are segment BC and segment CD.Since two sides and one included angle is equal △ACB≅△ECD under the SAS congruence criterion .

What is Coordinate Geometry?
By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related.
As per the given data:
We are given a line KL in the diagram, and we have to find out which point out of the given options will satisfy the equation of the line which is parallel to KL and passes through M.
Using the intercept form equation of line KL:
x/a + y/b = 1 [a and b are x and y intercepts respectively]
x/6 + y/4 = 1
4x + 6y = 24
Slope of this line = -a/b = -4/6 = -2/3
The line parallel to this will have the same slope and should pass through (-4, -2)
y - (-4) = (-2)/3 [x - (-2)]
y + 4 = (-2/3)[x + 2]
3y + 12 = -2x - 4
2x + 3y + 14 = 0
Clearly (8, -10) passes through this line.
2(8) + 3(-10) + 14 = 0
Hence, (8, -10) passes through this line.

Answers
Answer:
[tex]y=-\frac{4}{3}x +\frac{26}{3}[/tex]
Step-by-step explanation:
1) if the point A has coordinates (-1;10) and the point B - (5;2), then it is possible to write common view of the required equation of the line:
[tex]\frac{x-X_A}{X_B-X_A} =\frac{y-Y_A}{Y_B-Y_A};[/tex]
2) if to substitute the coordinates of A&B into the common equation, then:
[tex]\frac{x+1}{5+1} =\frac{y-10}{2-10}; \ => \frac{x+1}{6}=\frac{y-10}{-8};[/tex]
3) finally, in slope-intersection form:
3y= -4x+26; ⇔ y= -4/3 x +26/3.

These triangles are congruent under the SAS congruence criterion. The angles that face each other at the tip of these two triangles are vertically opposite angles, so their measures will be equal. It is already given that two sides of these two angles are equal. Since two sides and one included angle is equal, the SAS congruence criterion can be used to prove that this triangle is congruent.
Answer (b) :These triangles are congruent under the SSS congruence criterion. This criterion states that if all three sides of two triangles are equal then they are congruent triangles. Since two sides and one included/common side of these triangles are equal they can said to be congruent under the SSS congruence criterion.
Answer (c) :These triangles can be proved to be congruent using the SAS congruence criterion. Let us prove it using the following steps :
Given :
In triangle 1 :
Measure of an angle = 48°Measure of one of its side = 6 cmMeasure of another side = 6 cmIn triangle 2 :
Measure of an angle = 48°Measure of one it's side = 6 cmMeasure of another side = 6 cmSince two sides and one included angles of both these triangles are equal, we can conclude that they are congruent under the SAS congruence criterion.
