Answer:

Reflecting a point across the y-axis -> changes the sign of the x-coordinate

Reflecting a point across both axes -> changes the sign of both coordinates

Reflecting a point across the x-axis -> changes the sign of the y-coordinate

Step-by-step explanation:

Reflections:

  1. The rule to reflect a point across the y-axis is (-x, y), meaning that the x-coordinate's sign changes.
  2. Reflecting a point across both axes is the same thing as rotating it 180 degrees, so the rule is (-x, -y). This means that both coordinates' signs change.
  3. Reflecting a point across the x-axis is (x, -y), meaning that the y-coordinate's sign changes.

How to solve 3+5 (c+3)=-17
BlackZzzverrR [31]
3 + 5(c + 3) = -17

First, subtract 3 from both sides. / Your problem should look like: 5(c + 3) = -17 - 3
Second, simplify -17 - 3 to get -20. / Your problem should look like: 5(c + 3) = -20
Third, divide both sides by 5. / Your problem should look like: c + 3 =  -\frac{20}{5}
Fourth, simplify \frac{20}{5} to 4. / Your problem should look like: c + 3 = -4
Fifth, subtract 3 from both sides. / Your problem should look like: c = -4 - 3
Sixth, simplify -4 - 3 to get -7. / Your problem should look like: c = -7

Answer: c = -7

Someone please help! ATTACHMENT (just the circled one)
Elza [17]

4 (3x+9)-3(5y+7) =11

distribute

12x +36 -15y -21 =11

12x -15y +15 =11

subtract 15 from each side

12x -15y =-4

subtract 12x from each side

-15y= - 12x-4

divide by -15

y = -12/-15 x -4/-15

y = 4/5 x  + 4/15

slope = 4/5

y intercept = 4/15
