Just add the rows from the top to the bottom
10 1/2 = 21/2
(21/2) / 3
= 21/2 x 1/3
= 21/6
= 3 1/2

Answer:
Choice A:
. for all real numbers.
Step-by-step explanation:
We are looking for points on the x-y plane which satisfy the equation y = 5/2x + 3/2, and these point are all those that lie on the graph of the equation, which are points
.
Looking at the other choices we see that choice B gives only 3 points, and regardless of whether they lie on the graph of y or not, this choice cannot be correct because 3 points are not all solutions.
The same goes for choice D.
And choice C is just the whole of x-y plane, therefore this cannot be the answer because not every point on the x-y plane is a solution to y = 5/2x + 3/2
We know f(x)=5x+1. Plug in f(x) in the g(x) function.
We get

Distribute the 2 to 5x and 1.

Simplify to get

Now, we plug in -1 for x.


Answer:
26
Step-by-step explanation:
add both expressions to equal 90 (bc of the right angle)- x+11+2x+1=90
when you solve, you get x=26
