Answer:
-2x-y-15
Step-by-step explanation:
5x+3y+4-9x-8+2x-4y-11
you add the x together
5x+2x=7x
7x-9x=-2x
then yourewrite the problem
-2x+3y+4-8-4y-11
then you can solve for the y
3y-4y= -1y but you do not need to put the 1 since -y is the same as -1y
we can rewrite the problem again
-2x-y+4-8-11
4-8=-4
-4-11=-15
answer
-2x-y-15
Is this 13 and 34 ? or 1,3,3,4?
Answer:
Letter b is correct!
explanation:
The letter b is correct because it is the demand determinants that explain the changes in the aggregate demand curve. This is because the most important determinants of demand such as interest rate, Federal Deficit, expectations and money supply are not constant, so a change in any of these determinants will also affect the change in the aggregate demand curve.
Answer:
14.7
Step-by-step explanation:
a^2+b^2=c^2
15^2+b^2=21^2
225+b^2=441
subtract 441-225=216
square root of 216 = 14.6969384567
= 14.7
