A=11. to graph it plot an open circle on 11 and go right
Answer:
-4x-31
Step-by-step explanation:
1) Distribute:
(-13x-15)+(9x-16)
2) Eliminate parenthesis that are not useful:
-13x-15+9x-16
3) Subtract the numbers:
-13x-31+9x
4) Combine like terms:
-4x-31
Hope this helped!
The volume of a rectangular prism is the product of the three dimensions.
The width and length give the base area, which is 90.
So, if we multiply the base area and the height, we get the volume:
We know that V=1080 and w*l (i.e. the base area) is 90. So, we have
Let's call that the Multiplicative Identity Property.
1 is the identity element for multiplication. Those are just fancy words for the obvious property that anything times 1 is itself.
Answer:
x=-1
y=-1
Step-by-step explanation:
-6x + 5y =1 ......equation (1)
6x + 4y = –10 ......equation (2)
adding equation (1) to equation (2)
9y=-9
9y/9 =-9/9 (dividing both side by the coefficient of y)
y=-1
subtituting the value of y =-1 into equation (2)
6x+4(-1)=-10
6x+(-4)=-10
6x-4=-10
6x=-10+4(making constant to be at one side and the variable at the other side)
6x=-6
x=-6/6
x=-1
