If rectangle ABCD was reflected over the y-axis, reflected over the x-axis, and rotated 180°, where would point A' lie?

1 answer:

8 0

Point A was originally at (1, -1).
Refrection over the y-axis will take it to point (-1, -1).
Refrection over the x-axis will take it to point (-1, 1).
Rotation of 180 degrees will take it back to the original point of (1, -1)

Match each situation to its corresponding equation

Nitella [24]

First pair goes to f(x) = 20x
Next pair goes to f(x) = 10x + 20
Third pair goes to f(x) = 10x + 25
Last pair goes to f(x) = 20x + 10

3(2x + 5)= 4 (c-3) I know how to solve it but can someone explain it.

Nezavi [6.7K]

Answer:

3x×2c+1

Step-by-step explanation:

6x+15 =4c-12

$\frac{6x + 15}{4c - 12} = \frac{4c - 12}{4c - 12}$

$\frac{6x + 15}{4c - 12}$

$\frac{3x + 5}{2c - 4}$

$3x + 5 \div 2c - 4$

$3x \times 2c + 5 - 4$

$3x \times 2c + 1$

Write a rule/equation for each of the lines shown!!!!

Fofino [41]

For the line that has a positive slope, the equation is y = 2x - 1

This is because slope is rise over run(rise/run) or m = y₂-y₁ / x₂-x₁. The line goes up(rise) 2 units, and goes to the right(run) by 1 unit.

The y-intercept(the point the line touches when x = 0) is -1.

You use the equation y = mx + b, try to find m and b(y-intercept) and plug it into the equation.

For the line that has a negative slope, the equation is y = -x + 5

Rachel and her friends are making necklaces out of beads and straws. They plan to use 12 beads and 5 straws for each necklace. T

Answer:

225 necklaces.

Step-by-step explanation:

Assuming that they have the necessary amount of straws to match the beads then we can use the following simple equation to solve this problem.

t = b/12 ... where t is the total amount of necklaces and b is the number of beads you have

t = 2700 / 12

225 necklaces.

For 225 necklaces you would also need 1125 straws since each necklace requires 5 straws to be fully made. Therefore if you have this amount you should not run into any problems.
