<u><em>I am doing this problem assuming that you mean to solve for m and n as x and y do not exist in this system of equations.</em></u>
<u><em /></u>
-4m+2n=6
-4m+n=8
We can see that the coefficient of x for both equations are -4; therefore, elimination with subtraction is possible.
<u>First equation - second equation</u>
n=-2
<u>Then substitude back in to solve for m</u>
-4m+(-2)=8
4m=10
m=5/2
Therefore the answer is
n= - 2
m= 5/2
I hope this helped and if you have any questions please ask.
Answer:
D) 2x²+4x-30
Step-by-step explanation:
You would multiply x and 2x; x and -6; 5 and 2x; 5 and -6
(x)(2x) = 2x²
(x)(-6) = -6x
(5)(2x) = 10x
(5)(-6) = -30
Now just put it back in the order that it was listed in the equation starting with (x)(2x)
This would give you 2x²-6x+10x-30
Simplify even further to get 2x²+4x-30
So if each blade cost $23 you could add 23 8 times.
23+23+23+23+23+23+23+23= 184
or if you can do multiplication it could be
23x8=184
In total Jacob spent $184
Answer:
Step-by-step explanation:
Given:
This reads as: 256 to the power of "-4 to the power of 3/2".
Therefore, we need to deal with the "-4 to the power of 3/2" first.
Rewrite the 4 as 2²:
Therefore:
Replace "-4 to the power of 3/2" with -8 :
Rewrite 256 as 2⁸ :

Answer:
-83
Step-by-step explanation:
x+(x+1)=number
x+(x+1)=-165
2x+1=-165
-1 -1
2x=-166
/2 /2
x=-83
We can check our work by adding -83+-82=-165 because -83 would be the smaller number.
-83.
