Answer:
The answer in the procedure
Step-by-step explanation:
we know that
The rule of the reflection of a point over the y-axis is equal to
A(x,y) ----->A'(-x,y)
That means -----> The x-coordinate of the image is equal to the x-coordinate of the pre-image multiplied by -1 and the y-coordinate of both points (pre-image and image) is the same
so
A(3,-1) ------> A'(-3,-1)
The distance from A to the y-axis is equal to the distance from A' to the y-axis (is equidistant)
therefore
To reflect a point over the y-axis
Construct a line from A perpendicular to the y-axis, determine the distance from A to the y-axis along this perpendicular line, find a new point on the other side of the y-axis that is equidistant from the y-axis
Answer: 26
Step-by-step explanation:
lets replace a and b with the numbers provided
2+4(2+4)=2+4(6)=2+24=26
Answer:
x=35
'x-10'=25 degrees
'x'=35 degrees
The last one is 120 degrees
Step-by-step explanation:
A straight line is 180 degrees
180-60=120
2x+110=180
2x=70
x=35
Answer:
x=2
