Answer:
In vertex form, the parabola's equation is y=(x−1)^2 +5.
Step-by-step explanation:
The answer is D $126,if three cost $54 that means one costs $18 and just multiply it with seven
X-5.1 = -7.6
+5.1 +5.1
X= -2.5
1.) 3+2=? ?=5 brothers 2.) 54+9=? ?=63 students 3.) 15-9=? ?=4
4.) 60-20=? ?=40 children 5.) 50-15=? ?=35 trees 6.) 14+4=? ?=18 times
Don't know why you needed help with this but ok.
2/7 ( k+5/8) = 2 and 2/7
2/7 (k+5/8) = 16/7 |multiply by 7
2(k+5/8) = 16 |divide by 2
k+5/8 = 8 |subtract 5/8
k=8-5/8 = 7 and 3/8 = 27/8 = 7.375
