Which expression is equivalent to 18 - 7? Apex

Dominik [7]

Answer: See explanation

Step-by-step explanation:

Your question isn't complete but let me help out.

To get an expression that is equivalent to 18 - 7, you will have to know the value of 18-7 first. This will be:

= 18 - 7

= 11

Since we know that 18-7 = 11, then from the options that you're given, you'll find the one that is also equal to 12 which will be the answer.

For example, let's say you're given the options of a. 20 - 6 and b. 3 + 19 - 11.

20 - 6 = 14. This means that it isn't an equivalent of 18-7.

3+19-11 = 11. So, this is an equivalent of 18-7.

What are the possible values of x in 8x^2+4x=-1

Vladimir79 [104]

Answer:

$x1=-0.25(+)(0.25i)$

$x2=-0.25(-)(0.25i)$

Step-by-step explanation:

we have

$8x^{2}+4x=-1$

Factor the leading coefficient

$8(x^{2}+0.5x)=-1$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$8(x^{2}+0.5x+1/16)=-1+1/2$

$8(x^{2}+0.5x+1/16)=-1/2$

$(x^{2}+0.5x+1/16)=-1/16$

Rewrite as perfect squares

$(x+0.25)^{2}=-1/16$

remember that

$i=\sqrt{-1}$

$(x+0.25)=(+/-)(0.25i)$

$x=-0.25(+/-)(0.25i)$

$x1=-0.25(+)(0.25i)$

$x2=-0.25(-)(0.25i)$

Answer:

A. f + y ≤ 11

17f + 287 ≤ 242

Step-by-step explanation:

[] Let f be football players and v be volleyball players.

-> The total time must be less than or equal to 242 seconds.

-> If football players talked for 17 seconds, we can write it as 17f.

-> If volleyball players talked for 28 seconds, we can write it as 28v.

[] Coming back to the first point I made, the total time must be less than or equal to 242 seconds.

-> 17f + 28v ≤ 242

[] This is going to be a part of our system of inequalities

-> Because of this, we rule out the following options.

B & D - the football players talk for 17 seconds, not the volleyball players

C - not less than or equal too, only less than

[] This leaves us with the option of A.

-> The first part of it also works. If 11 players can talk to the crowd, then the total of f and v must be equal too or less than 11.

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

jasenka [17]

A.

When 0 is plugged in, it is 5*2^0=5*1=5, resulting in the point (0,5)

When 2 is plugged in, it is 5*2^2=5*4=20, resulting in the point (2,20)

Please can someone help my assignment

Vadim26 [7]

Answer:

Find answers below

Step-by-step explanation:

First know that any value raise to power zero is 1 and also according to the inverse law;

a⁻ⁿ = 1/aⁿ

Given the following

a) (-123)⁰ = 1 ()Note that any value raise to zero is 1

b) 43⁻⁵ = 1/43⁵

1/43⁵ = 1/147,008,443

c) 1/15⁻⁶ = 1/(1/15⁶)

1/(1/15⁶) = 1*15⁶/1

1/(1/15⁶) = 15⁶

d) -(1353348)⁰

= -1 (anything raise to zero is 1)

e) 13⁻⁴ = 1/13⁴

= 1/28,561
