Answer: 0.1 or 1/10

Step-by-step explanation:

\left(\frac{3}{4}-\frac{2}{3}\right)\cdot \:1\frac{1}{5}

1\frac{1}{5}=\frac{6}{5}

\left(\frac{3}{4}-\frac{2}{3}\right)\cdot \frac{6}{5}

  \frac{3}{4}-\frac{2}{3}    =\frac{9}{12}-\frac{8}{12}

=\frac{1}{12}

\frac{6}{5}\cdot \frac{1}{12}

Cross, cancel common factor

\frac{1}{2}\cdot \frac{1}{5}

=\frac{1}{10}

Write an equation of the line that passes through the points (2, -3) and is parallel to the x axis.
podryga [215]

Answer:

y=-3

Step-by-step explanation:

If the line is parallel to the x-axis then it is a horizontal line with slope 0. These lines have form y=b where b is the y-intercept or y value of all points. y=-3 is the line since (2,-3) is on the line.

Can You Guys Please Help???
Bezzdna [24]

Answer:


Step-by-step explanation:

The answer is c.


Proportional means a relationship of y = a constant multiplied by x


In this case, the constant is 7.


i.e. y = 7x


So if


x is 3, y is 21


x is 5, y is 35


x is 7, y is 49


and so on...


And there you have it.

Which is the correct first line for dividing the function
Firlakuza [10]

Given function is f(x) = x³ -12x +16.

We can write it as x³ +0x² -12x +16.

We need to write the numbers in order from left to right, so it would be {1, 0, -12, 16}.

Given factor is x -2 = 0, that means x = 2. So we need to divide the numbers by 2.

So correct way to divide the function would be 2 L 1, 0, -12, 16.

Hence, option C is correct.
