- 38z, because -10z - 28z = 38, but you have to change into addition and that will be equal -38z.

What numbers are a distance of 4\6 unit from 3\6 on a number line?<br><br>Please help me out.
sweet [91]

The numbers that are a distance of 4/6 unit from 3/6 on a number line are -1/6 and 7/6

<h3>What is the distance on a Number Line?</h3>

We want to know what numbers are a distance of 4/6 unit from 3/6 on a number line.

Add 4/6 to 3/6, and also subtract 4/6 from 3/6. That will give the two numbers.

3/6 + 4/6 = 3/6 + 4/6 = 7/6

3/6 - 4/6 = -1/6

Thus, the numbers that are a distance of 4/6 unit from 3/6 on a number line are -1/6 and 7/6

If f(x)=x*−81 and g(x)=(x−9)−1(x+9), find g(x)×f(x).
Nostrana [21]
F(x) = x²-81

g(x) = (x-9) -1(x+9)

= (x-9) -x-9


g(x) • f(x)



= [x²-81 ] • [ (x-9) -x-9 ]

=[ x²-81 ] • [ (x-x -9-9) ]
= [ x²-81 ] •[0-18]
= [ x²-81] •[ -18]

= -18•x² +-81•-18
= -18x²+1458

valina [46]

Amount to be paid back = $ 88,624.36

<u>Step-by-step explanation:</u>

Principal amount = $ 40,000

Rate of interest = 7.5%

Number of years = 11

A=P\left(1+\frac{r}{n}\right)^{n t}

Plugin the values as,

A=40000\left(1+\frac{7.5}{100}\right)^{11}

A=40000(1+0.075)^{11}

A=40000(1.075)^{11}

A=\$ 88,624.36
