2. The quotient of a number and -9 increased by 10 is 11.

Mathematics

Answer:

Step-by-step explanation:

This question isn't worded the greatest, there are two ways you can read this.

1.  The quotient of a number and -9, increased by 10, is 11

2. The quotient of a number, and -9 increased by 10, is 11

The first equation will look like this

\frac{x}{-9} +10 = 11

And the second will look like this

\frac{x}{-9+10}   = -11

So I have solved for both (I personally believe the second way of reading the question is the correct way)

Which ordered pairs in the form (x, y) are solutions to the equation
Ann [662]

Answer:

A, D

Step-by-step explanation:

Sub the x and y values into the equation. The x value is the first number in the coordinate, and the y value is the second number.

If the left side is equal to the right side, it is a solution.

Example:

4x-5y=24

4(-9)-5(-12)=24

-36+60=24

24=24

Remember: if the left side does not equal the right side, it is not a solution.

OAA', OBB', and OCC' are straight lines. Triangle ABC is mapped onto Triangle A'B'C' by an enlargement with center O. What is th
bazaltina [42]

Answer:

(D) 2

Step-by-step explanation:

The scale factor of the enlargement of ΔABC to ΔA'B'C' is given by the ratio of the length of the corresponding sides of ΔA'B'C' and ΔABC

Therefore, we have;

The \ scale \ factor = \dfrac{Length \ of \overline  {B'C'}}{Length \ of \overline {BC}} =  \dfrac{Length \ of \overline  {A'C'}}{Length \ of \overline {AC}} =  \dfrac{Length \ of \overline  {A'B'}}{Length \ of \overline {AB}}

\dfrac{Length \ of \overline  {B'C'}}{Length \ of \overline {BC}} =  \dfrac{2 \ units}{1 \ unit} = 2

\dfrac{Length \ of \overline  {A'C'}}{Length \ of \overline {AC}} =  \dfrac{4 \ units}{2 \ units} = 2

\dfrac{Length \ of \overline  {A'B'}}{Length \ of \overline {AB}} =  \dfrac{2 \cdot \sqrt{5}  \ units}{\sqrt{5}  \ units} = 2

Therefore, the scale factor = 2
