It moves five squares to the left because it is -5 so it’s decreasing
Solve for y by setting one equation =to X after that you can substitute the equation into the other one let's set the first one in X= FORM
X-7y=10
-2x+14y=-20
Add 7y to both sides of the first equation to let x stand alone
X=7y+10
Now you can substitute x on the second equation
-2 (7y+10)+14y=-20
Distribute
-14y-20+14y=-20
Add and simplify
Us cancel out =0
-20=-20
0=0
They are the same equations you can also divide the second equation by -2 which would make it look like this
X-7y=10
-2 (x-7y=10)
Let me know if I have answered your question
Answer:
9 units
Step-by-step explanation:
Given
Required
Determine the length of the longest segment
To do this, we use:
So, we have:
Take positive square root
<em>Hence, the length of the longest segment is 9 units</em>
A single angle is generally not considered to be supplementary. Supplementary angles are angles that equal 180° when they are added together. For example, 70° and 110° are supplementary because they equal 180°.
However, I guess the supplementary angle can be the angle that must be added to another to total 180°. For example, 80° is the supplementary angle of 100°.
Answer:
976 cm^2.
Step-by-step explanation:
The surface area = 2 * area of the triangular side + 2 * area of the rectangular sides + area of the rectangular base.
= 2 + 1/2 * 24 * 14 + 2 * 25 * 10 + 14*10
= 336 + 500 + 140
= 976 cm^2.
