(Q1) Which of the following is true about the function y = 3 • 2x?

Virty [35]

Answer: Third option

Step-by-step explanation:

You have the function:

$y=3*2^x$

Then, if the value of x increases by 1, you obtain:

-Rewrite the function:

$y=3*2^{(x+1)}$

-Substitute values for x into the function and observe what happen to y. Then:

x=1

$y=3*2^{(1+1)}=12$

x=2

$y=3*2^{(2+1)}=24$

x=3

$y=3*2^{(3+1)}=48$

The value of y is doubled.

What is wrong with this problem. 2(n +3) = 2n +3

LekaFEV [45]

Steps to solve:

2(n + 3) = 2n + 3

~Distribute left side

2n + 6 = 2n + 3

~Subtract 6 to both sides

2n = 2n - 3

~Subtract 2n to both sides

n = -3

How do you solve 10(z-2)=1+4

tamaranim1 [39]

I'm assuming you want us to solve for the unknown variable z

$10(z-2)=1+4$

Combine like terms on the right side

$10(z-2)=5$

Use the distributive property on the left side

$10z-20=5$

Add both sides by 20 to cancel out the "-20" on the left side

$10z=25$

Divide both sides by 10

$z=2.5$

That is the value of the known variable, z, in this equation. Let me know if you need any clarifications, thanks!
