What theorem shows that ΔACE ≅ ΔBCD? There are two triangles, triangle ACE and triangle BCD with common vertex C. The angle ACE and angle BCD are opposite angles. Side AC is congruent to side BC. Side EC is congruent to side

A. HL
B. AAS
C. ASA
D. SAS

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

the answer is two. hope this !
