Answer: y = 5x + 5
Step-by-step explanation: Okay follow these steps to get y alone.
2 ( y - 3 ) = 10x + 4
2y - 6 = 10x + 4
2y = 10x + 10
y = 10/2x + 10/2
y = 5x + 5
Answer:
The triangle is an acute equilateral triangle
Step-by-step explanation:
The triangle is acute because of all three angles measuring under 90 degrees.
It is also equilateral for all of its angles are of equal measurements and all three sides are congruent as well.
Answer: Option 4
Step-by-step explanation:
Direction: The vector is in the second quadrant, so the direction is about

8. The corresponding angles of similar triangles are congruent. Angle U corresponds to angle R, so the value of x will be the value of the unmarked angle in ∆PRQ. The sum of angles is 180°, so the unmarked angle (x) has measure ...
... x = 180° - 60° - 40° = 80° . . . . matches selection A
9. The ratio of the lengths of the original to its image is the same in all cases. The appropriate choice is ...
... B. AB/A'B' = BC/B'C'
The other choices have mixed ratios that don't make any sense.
10. The parallel base makes ∆RTU ~ ∆RQS and divides RQ in the same proportion it divides RS. The appropriate choice here is ...
... C. RT/TQ = RU/US
