Answer:
Multiply the second equation by -3 to get -3x - 9y = -30.
Step-by-step explanation:
When eliminating, you need to find a term with the negative of that term to combine so that they cancel each other out. An example would be 3x in the first equation and (-3x) in another equation so that when added, it becomes: 3x-3x = 0.
In the second equation, you see that there is already an x there and you just need to make it become (-3x). Thus, you multiply the entire second equation by -3 to make -3x. Once you have done that, you can combine the two equations and eliminate 3x from the first equation.
3x + 5y = 30
-3x - 9y = -30
3x + 5y -3x - 9y = 30 + (-30)
0 - 4y = 30 - 30
-4y = 0
<em>You can find y and then x later on from here. </em>
Answer A
They have the same x-intercept but different end behavior as x approaches ∞ :)
Yolanda will sew 54 buttons in 3 days.
If she sews 3 sweaters a day then, by the end of each day she will have 18. After three days she will have 54.
hope this helps and have an awesome day !
Answer:
Step-by-step explanation:
Mod of any number represents the absolute value of the number.
Therefore, 
= 2.25
Now we can arrange these numbers in ascending order.
-2.25 < -1.25 < 0.75 < 1.25 < 1.75 < 2.25
Therefore,
cannot be changed to a mixed number. 10 could divide both numerator and denominator. And you get 2.
