Answer:

  8 = 3x - 4y

or  y = (3/4)x - 2

Step-by-step explanation:

(4,1)  and (0, -2)  are the two points I see.

slope =  (1 -(-2))/(4 - 0) =  3/4

y-int:  -2

y = (3/4)x - 2

or   2 =  (3/4)x - y

  8 = 3x - 4y

Use unit rate to find the unknown value 16/32 equals blank over 14​
grigory [225]

Answer:

x = 7

Step-by-step explanation:

simplify 16/32

16/32 divided by 8/8=2/4

2/4 divided by 2=1/2

so

1/2 = x/14

to get to 14  from 2 you need to multiply by 7

1/2 times 2/2 = 7/14

so x = 7

Someone help me please:)
Kryger [21]

Answer:

a. The time to strike the ground is 5 seconds

b. The time for the ball to be over than 96 ft is 1 second

Step-by-step explanation:

a. When the ball thrown vertically up ward to reach its maximum height at velocity = 0 then complete its motion vertically down ward to strike the ground its displacement = zero

∴ s(t) = 0 ⇒ 80t-16t^{2}=0

∴16t(5 - t) = 0

5 - t = 0⇒ ∴ t = 5 seconds

b. To tind the time that the ball will be over 96 ft over the ground substitute in s(t)=80t-16t^{2}

96=80t-16t^{2}

16t^{2}-80t+96=0

16(t^{2}-5t+6)=0

16(t-3)(t-2)=0

t = 3 sec. and t = 2 sec.

The ball will be at height 96 ft at time 2 sec. and 3 sec.

So the ball will be at height over than 96 = 3 - 2 = 1 sec.
