Hope this helps !!!
Answer:
14. B
(6x^4 + 7x + 5x^3) - (4x^4 - 2x^3 + 3x)
2x^4 + 7x^3 + 4x
15. 150
The missing dimension is 12
The rectangle formed has an area of 120 the small triangle has an area of 30
16. C=
C= 25.60(4) + 14(4) (3-1)
C= 102.4 + 112
C= 214.4
17. B
-5 = -3/4 (8) + 1
-5 = -6 + 1
-5 = -5
the equation is true
Answer:
It has two solutions.
Step-by-step explanation:
The correct answer is D, y = 7x + 5
Calculate the slope by doing y2 - y1 / x2 - x1
y2 - y1 / x2 - x1
61 -33 / 8 - 4
28 / 4
7
Next find the y intercept by looking at the graph, which is 5 in the case
Put it together and you have y = 7x + 5, or option D
(8, 9) will be the midpoint of the segment.
You can find this by applying the formula
(x1 + x2)/2 , (y1 + y2)/2
