Answer: x=-5
Step-by-step explanation:
You would have to do the inverse to “undo” the equation.
So first you would do -7-3=-10
Then you would do -10/2=-5 to find x
Answer:
(LAST OPTION)
Step-by-step explanation:
You have the following expression given in the problem:

If the expression on the left side of the equation is equal to the expression on the right side of the equation, and the problem asks to rewrite it as a system, you can conclude that the first equation is:

And the second equation is:

Therefore, you can set up the following system of equations:

Answer:
option A is correct.(Every plane must have three intercepts.)
Step-by-step explanation:
" Three-dimensional space (also: 3-space or, rarely, tri-dimensional space) is a geometric setting in which three values (called parameters) are required to determine the position of an element (i.e., point). This is the informal meaning of the term dimension "
The intercept form of the equation of plane in 3-D is given by:

Where l,m,n are intercepts of x,y,z axes and a plane respectively.
Hence, we require all the three intercepts of a every plane.
Hence, option A is correct.
Answer:
36 units squared
Step-by-step explanation:
Since this is kind of a weird shape, we can split it into two smaller shapes, a triangle, and a rectangle.
The rectangle is 6 units wide, and 4 units long. Multiply the length and width to get 24 units squared.
The triangle has a base of 6 and a height of 4, so multiply the base and height, then divide by 2. 6 times 4 is 24 and that divided by 2 is 12.
Finally add the two areas together. 24+12=36 units squared.
Answer:
y = 6
Step-by-step explanation:
Perform the indicated multiplication: 6y + 12 = 8y
Consolidate y terms on the right: 12 = 8y - 6y = 2y, or y = 6
