Answer:
If you translate the center of circle y up 6 units and to the left 6 units and then dilate the circle with a scale factor of 2, circles x and y would be congruent.
Step-by-step explanation:
If you translate the center of circle y up 6 units and to the left 6 units and then dilate the circle with a scale factor of 2, circles x and y would be congruent.
First we need to find the slope of the original equation
2x - 3y = 3
-3y = -2x + 3
y = 2/3x - 1....the slope here is 2/3.
However, we need a perpendicular line...so we need to use the negative reciprocal slope. All that means is flip the slope and change the sign.
slope 2/3.....flip.....3/2....change the sign...-3/2.
so our perpendicular line will need a slope of -3/2.
y = mx + b
slope(m) = -3/2
(-8,2)...x = -8 and y = 2
now we sub and solve for b, the y int
2 = -3/2(-8) + b
2 = 12 + b
2 - 12 = b
-10 = b
so our perpendicular line is : y = -3/2x - 10

im not 100% but i think its
T= 2t-4+(t-4)+7
Answer:
The equation of the line is y=-x
Step-by-step explanation:
To find the equation for a line, we need to know 2 points.
One of the points is (0,0) because it goes through the origin. Another point is (5,-5). We can calculate the slope because we have 2 points using the formula.
m = (y2-y1)/(m2-m1)
m = (-5-0)/(5-0)
m = -5/5
m=-1
The slope is -1
We know the y intercept (where it crosses the y axis) is 0. Using the slope intercept form of a line
y = mx+b
y =-1x+ 0
y = -x
The equation of the line is y=-x
Answer: 16
Step-by-step explanation:
3/8 times ? equals 6
6 divided by 3/8 = ?
6 3
÷
1 8
keep change flip
