The equation is y=1.55X+110,419 and they give you X so put that in: y=1.55(78,300)+110,419. Now you multiply: 1.55(78,300)=121,365, y=121,365+110,419. Now add: 121,365+110,419=231,784 :)
The graph means that 2 x and 9.4 make up 20 in total, so set up the equation 2x + 9.4 = 20.
Subtract 9.4 from both sides.
2x = 10.6
Divide by 2.
x = 5.3
The answer is the value of x that makes this equation true is 5.3
Hope this helps
It’s the third choice because the highest degree is three and there are three terms. FOR QUESTION 3
The first two choices for QUESTION 4
9a-4+3a-33=23
9a+3a-29=23
+29 +29
9a+3a=52
-3a -3a
9a=52-3a
9a/9=52/9- 3a/9
a=52/9-1/3a
