Eleven times a number? Sounds like multiplication problem.

11 * ?

But multiply by what? We don't know. It just says 'a number'. In algebra, we use variables to represent a number.

11 * x

Or you could do 11x. In algebra, it means the same thing.

Write the sentence as an inequality. The cost of a ticket t will be no more than $52.

NeX [460]

Answer:

t is less than or equal to $52, or t <= $52

Step-by-step explanation:

If you can't have more than $52, then use less than symbol (<). The sentence doesn't state that a ticket shouldn't cost $52, so it's safe to assume that you can have exactly $52.

weeeeeb [17]

In 2000 Emily was 9 years old.

Given that in the year 2015 Emily was three times as old as Kaitlin while by the year 2021 Kaitlin will be half as old as Emily will be, to determine how old was Emily on the year 2000 the following calculation must be performed:

2015 = E = 3K
2021 = E = 2K
24 /// 8 --- 30 /// 14
18 /// 6 --- 24 /// 12
18/6 = 3
24/12 = 2
2015 = Emily was 24 years old
24 - (2015 - 2000) = X
24 - 15 = X
9 = X

Therefore, in 2000 Emily was 9 years old.

4vir4ik [10]

Hi,

During halftime of a soccer game, a slingshot launches T-shirts at the crowd. A T-shirt is launched from a height of 5 feet with an initial upward velocity of 72 ft. Per second. The T-shirt is caught 34 feet above the field. How long will it take the T-shirt to reach its maximum height? What is the maximum height? What is the range of the function that models the height of the T-shirt over time.

Write the general equation that represents height of the t-shirt as a function of time.

f(t) = -16 $t^{2}$ + 72t + 5

2. What is the maximum height of the t-shirt?

$t = \frac{-72}{2(-16)} = 2,25$ $f(2,25) = -16(2,25)^{2} + 72(2,25) + 5$

$= 86 feet$

1. How long will it take the t-shirt to reach its maximum height?

2,25 secondes

3. The range describes which values of the graph? What would the range of this graph be? (Write in inequality and interval notation).

height (y)

5 ≤ y ≤ 86 [ 5,86 ]

Find the constant of variation k for the direct variation 2x +6y = 0

scoray [572]

A relationship between two variables in which one is a constant multiple of the other. The constant here is also called the constant of variation. In order to obtain this value, we manipulate the equation by isolating the variables. We do as follows:

2x +6y = 0
y = -x/3

Therefore, the constant of variation is -1/3. Hope this answers the question. Have a nice day.
