Anon25 [30]3 years ago

X is equal to -7
First we distribute the 3 into the 2
Which gets us
6x+6=3x+−15
We then subtract 3x from both sides and we get
3x+6=-15
We later subtract 6 from both sides, in order to get
3X=-21
We then divide -21 by 3 and we get -7.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the
worty [1.4K]

Answer:

The maximum height is 1087.06 ft.

Step-by-step explanation:

We need to take the derivative of the equation and set it to 0.

y' = - 32x + 254 = 0\\32x = 254\\x = 7.9375

We now can plug x = 7.9375 into the original equation.

y=-16x^{2} +254x+79\\y=-16(7.9375)^{2}+254(7.9375)+79\\y=1087.06 ft

Solve an equation for one variable
AysviL [449]
To solve an equation for one variable, we will utilize PEMDAS ( parentheses, exponents, multiplication/division, add/subtract) but backwards. So we will first add/subtract any numbers to the other side to get the variable by itself. We will then divide/multiply any numbers to get the variable by itself.

If you a flip a coin 6 times, what is the probability that you will get exactly 4 times?
Luden [163]

Answer:So the number of outcomes with exactly 4 tails is 720/2/24 = 15. Finally we can now calculate the probability of getting exactly 4 tails in 6 coin tosses as 15/64 = 0.234 to 3 decimal places.

Evaluate each of the expressions in the list for y = 5. Drag and drop the correct number into each box to
malfutka [58]

Answer:

Step-by-step explanation:

To get the value of the expressions in list A and list B we will substitute y = 5 in each expression.                      

            List A                                        List B

1). 6 + 6y = 6 + 6(5) = 36              6y - 6 = 6(5) - 6 = 24

2). 6(y - 1) = 6(5 - 1) = 24               6(y + 1) = 6(5 + 1) = 36

3). 6y + 1 = 6(5) + 1 = 31                 1 + 6y = 1 + 6(5) = 31

Therefore, (6 + 6y) is equivalent to 6(y + 1)

6(y - 1) is equivalent to (6y - 6)

(6y + 1) is equivalent to (1 + 6y)
