Answer:

<h2>Anja's mistakes is solving coefficients, she must divide.</h2>

Step-by-step explanation:

The given expression is

\frac{10x^{-5} }{-5x^{10} }

Anja simplfied to

\frac{15}{x^{15} }

Anja did well powers, however, she did wrong coefficients, instead of dividing them, she subtracted them as she did with powers.

Therefore, Anja's mistakes is solving coefficients, she must divide.

\frac{10x^{-5} }{-5x^{10} }=-\frac{2}{x^{15} }

Which of the following is the graph of the absolute-value parent function?
Ne4ueva [31]
Should have the ordered pairs of
(-4,4) (-3,3) (-2,2) (-1,1) (0,0) (1,1) (2,2) (3,3).

Will look like a V when graphed. Reason being is if you take the absolute value of anything you are basically just dropping the negative sign as it is how far away it is from 0.

Ryan invested his savings in two investment funds. The $24,000 that he invested in Fund A returned a 6% profit. The amount that
Viefleur [7K]

Answer:

the sum invested in Fund b is $6000

Step-by-step explanation:

This question can be easily solved using allegation Method.

Profit on fund A is 6% whereas Profit on fund B is 2%.

Fund A + Fund B= $24000

Overall profit to be gained = 5%

                             6%            2%

                                      5%

                             3       :          1

therefore the fund was distributed in the ratio 3:1

⇒4 units= 24000

⇒ 1 unit = $6000

therefore the fund A = 3×6000=$ 18000

and the fund B= 1×6000= $6000

Which linear function rule models the table below? (0,6) (5,9) (10,12) (15,15)
Dovator [93]

Answer:

y= 0.6x + 6 or y= 3/5x + 6

Step-by-step explanation:

The function for a linear function is y=mx+b.

We know that b is 6 because that is the y-intercept.

However to find m we need to see how much the x coordinates skip on the table and the y coordinates. We can see that x coordinates skip by 5s and the y corrdinates skip by 3. We than divide 3/5 to get o.6 and we get the equation. This video, tittled "Writing A Linear Equation From A Function Table" explains it much better than I can.
