Answer:

e = 9

Step-by-step explanation:

4e - 10 = 2e + 8

=> 4e + (-2e) - 10 = <u>2e + </u><u>(-2e)</u><em> </em>+ 8

=> 2e -10 = 8

=> 2e <u>-10 + </u><u>(+10)</u> = 8 (+10)

=> 2e = 18

=> <u>2</u>e<u>/2</u> = 18/2

=> e = 9

Hope this helps!

Answer:

e = 9

Step-by-step explanation:

ok e is just x, so we have to get it alone

4e - 10 = 2e + 8

We move the 2 since its smaller than the 4, and we move it two the other side. 4-2=2 so the new e is 2, now that 8 is alone (since we moved the 2), we cant be having the e with the -10... like this..

2e - 10 = 8, so we now add 10 so it can go with the 8, the new equation is this..

2e = 18

18/2 = 9

simple explanation

4e - 10 = 2e + 8

2e = 18

e = 9

(does that make sense)

What is the vertex of the graph of this equation y=2x^2+8x-24
sdas [7]

Answer:

The vertex would be D) (-2, -32)

Step-by-step explanation:

To find the vertex , start by find the x-value. For this we can use the equation below.

x = -b/2a

In which a is the coefficient of x^2 and b is the coefficient of x.

x = -b/2a

x = -(8)/2(2)

x = -8/4

x = -2

Now that we have x, we find y by plugging -2 in for each x.

y = 2x^2 + 8x - 24

y = 2(-2)^2 + 8(-2) - 24

y = 2(4) - 16 - 24

y = 8 - 16 - 24

y = -32

An investigation with a set set of individual tests, each only with two possible results.

Four conditions are met by the binomial experiment

  • Each attempt is autonomous.
  • 2 potential results exist only.
  • In each and every test, the probability of each outcome remains unchanged.
