Select the correct answer The number of hours that 20 people spent watching television per day, in relation to age, is graphed. This quadratic equation represents the
model for the set of data.
y = 0.00422 - 0.314x + 7.5
Based on the model, approximately how much time does an 18-year-old spend watching television each day?
ОА.
3 hours
ОВ.
7.5 hours
Ос. .
2 hours
OD
0.5 hour

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

you save $70

discount would be 35% off

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
