=-17/40+-3/8+5/4
= -4/5+5/4
= 9/20
And the answer is 9/20 or decimals (0.45)
Answer:
part A:d=5.4-3.1
Part B:t=4.9+3.1
Part C:If ted walks 5.4 kilometers,then david walks 2.3 kilometers,If david walks 4.9 kilometers,then ted walks 8 kilometers.
Answer:
1/2(3)-2/3(8)
3/2-9/3
<u>3</u>-<u>9</u>
2.3
<u>9</u><u>-</u><u>3</u><u>2</u>
6
<u>-23</u>
6
So area=1/2 base times height
50=1/2 base times height
multiply both sides by 2
100=base times height
base=4height
100=4height times height
100=4height^2
divide 4
25=height^2
squarer root
5=height
subisute
base=4(5)
base=20
height=5
Answer:
(7,-3)
Step-by-step explanation:
y = -3
substitute in the first equation
3x - y^2 = 12
3x - (-3)^2 = 12
3x - 9 = 12
3x = 12 + 9
3x = 21
x = 7
coordinates of intersection (7,-3)
