Answer:
angle B'CA'= angle BCA..... (common angle)
angle B'A'C = angle BAC.....(corresponding angels)
therefore,
ΔCB'A' ~ ΔCBA. ......(by A-A test of similarity)
therefore,
B'A'/ BA. = CA'/ CA....(congruent sides of congruent triangles)
now, B'A' = 5, CA'= 6 , CA = 6 + 3 = 9
5 / BA. = 6 / 9
therefore, 5 / BA. = 2 / 3
Answer : AB = 7.5 units

Answer:
2y -x = -6
Step-by-step explanation:
You can use the same x- and y-coefficients. You just have to change the constant on the right. Put the point values into the left expression to see the new constant.
2y -x = 2(-1)-(4) = -6
The parallel line is ...
2y -x = -6
When you are given an equation or an expression and told the values for the variables, you can just substitute them into the equation to solve:
8b^2 - 5m + 12
8(6)^2 - 5(8) + 12
8(36) - 40 + 12
288 - 40 + 12
248 + 12
260
Answer:
260
