Answer:
x= -b/2a
Step-by-step explanation:
hello :
y = ax²+bx+c .... (a≠0)
the equation of the axis of symmetry of this graph is : x= -b/2a
Answer:
A. <T=17, RS= 10
Step-by-step explanation:
These triangles are congruent by AAS congruency. This means that RS and UV will have the same measure and so will <Q and <T. Simply use that info with the measurements given.
Solving for <T:
8y-44 = 5y+7
3y = 51
y = 17
Solving for RS:
7x-2 = 5x+18
2x = 20
x = 10
-8x + 4y = 20
-8x + 8x + 4y = 8x + 20
4y = 8x + 20
4 4
y = 2x + 5
