Answer:

x = 4

Step-by-step explanation:

2x + 6 = 7x - 14

-7x        -7x

-5x + 6 = -14

      - 6    - 6

-5x = -20

/-5      /-5

x = 4

Check your answer:

2x + 6 = 7x - 14

2(4) + 6 = 7(4) - 14

8 + 6 = 28 - 14

14 = 14

This statement is true

Hope this helps!

If function fhas zeros at -3 and 4graph could represent function 1
goldfiish [28.3K]

Answer:

All the graph in attachment ate possible solutions.

Step-by-step explanation:

The graph that has zeros at -3 and 4, will intersect the x-axis at x=-3 and x=4.

The function could be a parabola that opens up or down and intersects the x-axis at x=-3 and x=4.

It could also be a fourth degree polynomial.

A restaurant gat an average of 14 calls in a 2 hr time period. What is the probability that at most 2 calls in 45 min period
rodikova [14]

Answer:

0.10512

Step-by-step explanation:

Given the following :

Mean number of calls(μ) in 2 hours = 14

2 hours = 60 * 2 = 120 minutes

Average number of calls in 45 minutes :

= (45 / 120) * 14

= 0.375 * 14

= 5.25

Now find P( x ≤ 2) = p(x = 0) + p( x = 1) + p(x = 2)

Using the poisson probability formula:

P(x, μ) = [(e^-μ) * (μ^x)] / x!

Where :

e = euler's constant

μ = 5.25

x = 0, 1, 2

Using the online poisson probability calculator :

P(x, 5.25) = P( x ≤ 2) = p(x = 0) + p(x = 1) + p(x = 2)

P(x, 5.25) = P( x ≤ 2) = 0.00525 + 0.02755 + 0.07232 = 0.10512

PLEASE HELP Two prisms are composed to form a V shape. The thickness of each prism is 1 unit, and width of each prism is 2 units
Grace [21]

Answer:

  7 units, 8 units

Step-by-step explanation:

Apparently, the cross section of each prism is a rectangle 1 unit by 2 units. Hence the total length will be ...

  (30 units³)/((1 unit)(2 units)) = 15 units

Two numbers that differ by 1 and have a sum of 15 are 7 and 8.

The lengths of the prisms are 7 units and 8 units.

Rita is spending more time at home to study and practice math. Her efforts are finally paying off. On her first assessment she s
kogti [31]
Hey, looks like when she doesn't study, she ALWAYS fails. Don't mean to insult though.

Let's see the difference between the three numbers. 63-58=5. 68-63=5.

We know the difference between each assessment she scores is 5 now!!

Let's put it to use.

Although you don't have multiple choice answers... 

after 4 assessments(not including first 3), her score will be above 85!!

Including the first 3 assessments, her score would be above 85 after 7 assessments!!

anyways, I hope this helps!!
