Answer:
2x^2-6x-4
Step-by-step explanation:
(7x2 + 4x - 9)
-(5x2 + 10x - 5)
=
7x^2-5x^2=2x^2
4x-10x=-6x
-9-(-5)=-4
thus, your answer is 2x^2-6x-4

A group of friends went fishing. They each caught 20 fish but not all of them were keepers. Which person was able to keep 3/5 of the fish that he or she caught?
Answer:
Those who were able to keep 12 fishes
Step-by-step explanation:
Given
Total = 20 (each)
Required
Which was able to keep 3/5
First, we need to calculate 3/5 of the total number of fishes
Fish = 3/5 * 20
Fish = (3 * 20)/5
Fish = 60/5
Fish = 12
From the calculation above, only those who keep 12 of the 20 fishes were able to keep 3/5 of their fishes

Mai is flying a plane at an altitude of 1600 ft. She sights a stadium at an angle of
depression of 35°. What is mai’s approximate direct distance to the stadium?
Answer:
2,789ft
Step-by-step explanation:
The set up will give a right angled triangle.
The altitude will be the opposite side = 1600 ft
The angle of depression = 35°
approximate direct distance to the stadium is the hypotenuse of the trisngle= x
Using the SOH trig identity to get the distance
sin 35 = opp/hyp
sin 35 = 1600/x
x = 1600/sin35
x = 1600/0.5736
x = 2,789.4ft
Hence mai’s approximate direct distance to the stadium is 2,789ft

Answer:
x= 0
y= -3
Step-by-step explanation:
6x-5y=15
substitution...
6(y+3)-5y=15
6y+18-5y=15
y+18=15
-18 -18
y= -3
substitution again...
6x-5(-3)=15
6x+15=15
-15 -15
