Answer:

x = 12

Step-by-step explanation:

This is a multi-step equation.

The first thing we can do is add 9 to both sides, eliminating the -9 from the left side of the equation. Now we have 7x = 84.

You can divide 84 over 7x to get a total of x =12.

Answer:

x = 12

Step-by-step explanation:

Step 1: Add 9 to both sides.

  • 7x - 9 + 9 = 75 + 9
  • 7x = 84

Step 2: Divide both sides by 7.

  • \frac{7x}{7} = \frac{84}{7}
  • x = 12

Step 3: Check if solution is correct.

  • 7(12) - 9 = 75
  • 84 - 9 = 75
  • 75 = 75

Therefore, x = 12.

What is
Tpy6a [65]

5/6 - 3/8

Rewrite the fractions to have a common denominator:

5/6 x 4 = 20/24

3/8 x 3 = 9/24

Now you have 20/24 - 9/24 = 11/24

The answer is D. 11/24

Hi please answer and you dont NEED to show work but if u do i will give brainliest
Advocard [28]

Answer:

y=-\frac{2}{5} -1

Step-by-step explanation:

So first thing is that slope intercept form is setup like this

y=mx+b

m=slope

b=y intercept

the slope is change in y over change in x

as y goes down 2 x goes up 5

so the slope is -2/5

the y intercept is at (0,-1) so the y intercept is -1

therefore the answer is

y=-\frac{2}{5} -1

have a great day :)

A ball is thrown vertically upward from the ground with an initial velocity of 111 ft/sec. Use the quadratic function h(t) = −16
ddd [48]

Answer:

t=3.5 seconds

Step-by-step explanation:

Given

h(t) = −16t^2 + 111t + 0

h'(t)= -32t + 111

Maximum height occurs when h(t) = 0 and the ball begins to fall

h(t)= -32t + 111=0

-32t + 111=0

-32t=-111

Divide both sides by -32

t=3.46872

Approximately, t=3.5 seconds

Recall,

Maximum height occurs when h(t) = 0

h(t)= -32t + 111=0

= -32(3.46872)+111

= -110.99904+111

= 0.00096 ft
