Answer:

C

Step-by-step explanation:

So we have:

\frac{6^{\frac{3}{10}}}{6^\frac{1}{5}}

To simplify, we can use the quotient rule of exponents, which says that if we have:

\frac{x^a}{x^b}

Then this equals:

=x^{a-b}

So, our equation will be:

\frac{6^{\frac{3}{10}}}{6^\frac{1}{5}}\\=6^{\frac{3}{10}-\frac{1}{5}}

Subtract the exponents. Turn 1/5 into 2/10 by multiplying both layers be 2. Thus:

6^{\frac{3}{10}-\frac{1}{5}}\\=6^{\frac{3}{10}-\frac{2}{10}}

Subtract in the exponent:

=6^{\frac{1}{10}}

So, our answer is C :)

Was there a typo in the possible answers by any chance? B is closest to the possible answer, but only if the division sign was a multiplication sign.
102 <span>÷ 6 = 17
102 </span><span>÷ 17 = 6
17 x 6 = 102
6 x 17 = 102</span>

Damian works after school. Each
nadya68 [22]

Answer:

f(x) = 12x = 10

Step-by-step explanation:

We need a linear equation in the slope-intercept form.

y = mx + b

where y = total pay, m = hourly salary, x = number of hours worked, and b = y-intercept, or initial value

Let's look in the table.

1 hour: $22

2 hours: $34

The difference in pay between 1 hour and 2 hours is $34 - $22 = $12.

The difference in time between 1 hour and 2 hours is 1 hour.

In 1 hour he earns $12. That means the slope is 12.

We know he earns $22 for working a total of 1 hour.

Start at 1 hour and $22 on the table.

Subtract 1 hour from 1 hour to get 0 hours.

Subtract $12 form $22 to get $10.

That means for 0 hours he gets $10. b = 10

The equation is

y = 12x + 10

In function form, we have:

f(x) = 12x = 10

Use slopes to determine if the lines 4x−7y=9 and 7x+4y=5 are perpendicular.
KIM [24]

Answer:

Perpendicular.

Step-by-step explanation:

4x - 7y = 9 ---> 7y = 4x - 9 ---> y = 4/7 x - 9/7, slope= 4/7

7x + 4y = 5 ---> 4y = - 7x + 5 ---> y = - 7/4 x + 5/4, slope = - 7/4

lopes are negative-reciprocal , so these lines are perpendicular.

I NEED HELP ASAP plsssssssssssssssss​
Novay_Z [31]

Answer:

(-4,-2)

Step-by-step explanation:

first u should chose a variable to eliminate and i choose Y

y=5/2x+8-y=-1/4x-3

get a common denominator

5/2= 10/4

-1/4=-1/4

the equation i will change a little because we are subtracting

10/4x+8+1/4x+3

11/4x+11

solve for the remaining variable which is X

subtract 11 on both sides

0-11=11/4x+11-11

-11=11/4x

multiply both sides by 4/11

-11 times 4/11= 11/4x times 4/11

x=-4

then substitute the variable in one of the equations and i choose y=5/2x+8

5/2(-4)+8= y

-20/2+8= y

-10+8=y

y=-2
