Answer:
(5,-1) or x=5 y=-1
Step-by-step explanation:
I used the substitution method to solve this!
<em>1. Pick one of your equations and solve for one of the variables. I chose the first equation and solved for x.</em>
x-2y=7
(Move the -2y to the other side of the equation in order to get the x by itself. You do the opposite, so it becomes +2y.)
x=2y+7
<em>2. Now take your second equation and plug in what you got for x into the x variable.</em>
2(2y+7)+5y=5
(Multiple 2 by everything inside of the parentheses.)
4y+14+5y=5
(We want to get the y by itself, so move the 14 to the other side.)
4y+5y=-14+5
(Combine all the like terms.)
9y=-9
(Divide the 9 from the y. What you do to one side you must do to the other.)
y=-1
<em>3. Since you have one variable solved for. Now take the first equation and plug in your y.</em>
x-2(-1)=7
(Multiple -2 by -1)
x+2=7
(Move the 2 to the other side in order to get the x by itself.)
x=5
<em>4. If needed, plug in your x and y values into the equations in order to check your answer.</em>
Hope this could help!
Answer:
x=5
Step-by-step explanation:
four times two x gives you 8x. 4 times 4 is 16. Subtract 16 from both sides you get 40. divide 8x by 8 and the eights cancel out. Divide 40 by 8 and you get 5
Answer:
I maybe could help you a little bit It seems the the angles <1 and < 3 are the same so I would suspect that < 3 would also be 126 degrees but same goes for < 2 and < 4

Answer:
4 2/3
Step-by-step explanation:
2 , 4, 6, 5, 4, 4, 5, 4, 8
Add the data together then divide by the number of data points
(2 + 4+ 6+ 5+ 4+ 4+ 5+ 4+ 8) /9
42/9
4 2/3
