b.

d.
-1

Answers

Answer 1

Answer:

X= -1

Step-by-step explanation:

[tex](\frac{1}{3} )(6x)+(\frac{1}{3} )(-15)=(\frac{1}{2} )(10x)+(\frac{1}{2} )(-4)[/tex]

(Distribute)

2x+−5=5x+−2

2x−5=5x−2

Step 2: Subtract 5x from both sides.

2x−5−5x=5x−2−5x

−3x−5=−2

Step 3: Add 5 to both sides.

−3x−5+5=−2+5

−3x=3

Step 4: Divide both sides by -3.

Which = -1

Hope this helps :)

-2(z+3)-z=-z-4(z+2)
solve for z quickly please! will give brainliest

Answers

Answer:

[tex] \sf z = - \dfrac{2}{3} [/tex]

Step-by-step explanation:

Solve for z:

[tex] \longrightarrow [/tex] -2(z + 3) = -z - 4(z + 2)

-4(z + 2) = -4z - 8:

[tex] \longrightarrow [/tex] -2(z + 3) = -z -4z - 8

Grouping like terms, -z - 4z - 8 = (-z - 4z) - 8:

[tex] \longrightarrow [/tex] -2(z + 3) = (-z - 4z) - 8

-z - 4z = -5z:

[tex] \longrightarrow [/tex] -2 (z + 3) = -5z - 8

Expand out terms of the left hand side:

[tex] \longrightarrow [/tex] -2z - 6 = -5 z - 8

Add 5z to both sides:

[tex] \longrightarrow [/tex] (5z - 2z) - 6 = (5z - 5z) - 8

5z - 5z = 0:

[tex] \longrightarrow [/tex] (5z - 2z) - 6 = -8

5z - 2z = 3z:

[tex] \longrightarrow [/tex] 3z - 6 = -8

Add 6 to both sides:

[tex] \longrightarrow [/tex] 3z + (6 - 6) = 6 - 8

6 - 6 = 0:

[tex] \longrightarrow [/tex] 3z = 6 - 8

6 - 8 = -2:

[tex] \longrightarrow [/tex] 3z = -2

Divide both sides of 3z = -2 by 3:

[tex] \longrightarrow [/tex] [tex] \sf \dfrac{3}{3}z = - \dfrac{2}{3} [/tex]

[tex] \sf \dfrac{3}{3} = 1 :[/tex]

[tex] \longrightarrow [/tex] [tex] \sf z = - \dfrac{2}{3} [/tex]

Which of the following is the graph of the inverse of f(x)=2x-3

Answers

Answer:

(-3,0) (0,1.5

Step-by-step explanation:

The answer choice which is the graph of the inverse of f(x)=2x-3 is; the graph of; f(x) = x/2 + 1.5.

What is the graph of the inverse of f(x)=2x-3?

It follows from the task content that the function given is; f(x)=2x-3.

Hence, to find the inverse function;

y = 2x - 3x = y/2 + 1.5.

Interchange the variables;

y = x/2 + 1.5.

On this note, it follows that the inverse function is;

f(x) = x/2 + 1.5

The graph of the inverse function therefore has points; (0, 1.5) and (2, 2.5) as points on the graph.

It is the 5th Blue one:) We know this because the y-intercept is -2.

Answer:

I can see how this is confusing, because of -2, but the slope is decreasing, so the question wouldn't say:

[tex]-3/5x - -2[/tex]

This happens to turn the -2 into a regular 2 with an addition (+) sign.

and since the graph has an input of 5 but an output of -3, the equation would be:

y = -3/5x + 2

Many credit card companies charge a compound interest rate of 1.8% per month on a credit card balance. Miriam owes $550 on a credit card. If she makes no purchases or payments, she will go more and more into debt.

A. 550.00, 649.00, 765.82, 903.67, 1,066.33, ...

B. 550.00, 559.90, 569.80, 579.70, 589.60, ...

C. 550.00, 559.35, 568.86, 578.53, 588.36, ...

Please also explain how (steps) to get the answer, thank you!

Answers

Answer:

D. 550.00, 559.90, 569.98, 580.24, 590.68, ...

Step-by-step explanation:

So, her debt will increase of the interest rate of 1.8% on a credit card.

You have to multiply the rate by the amount that she owes. So, when you multiply 1.8% by $550 you get $9.90 amd you habe to add that to what she owes. You can't keep adding $9.90 because now her debt increased from $550 to $559.90. You now have to multiply $559.9 by 1.8% inorder to get her new amount of debt. If you multiply 1.8% by $550, then you are saying that she only has $550 as debt even though she now has $559.90 im debt. You must keep multiplying her new amount of debt by 1.8% to get her increasing monthly balance.
