7h + 6b = 35.50
5h + 6b = 30.50
The difference between the 2 totals spent is $5, and there were the same number of burgers, but 2 fewer hotdogs. So $5/2 = $2.50, the cost of a hot dog. Substitute that into the equations to solve for burgers (b)
5(2.50) + 6b = 30.50
12.50 + 6b = 30.50
6b = 18
b = 3
Check the work:
7(2.50) + 6(3) =
17.50 + 18 = 35.50
Answer:
vertex =
(
4 , 25
)
Step-by-step explanation:
given a parabola in standard form y
= a
x
2
+
b
x
+
c
x
;
a
≠
0
then the x-coordinate of the vertex is
X vertex=-b/2a
y=-x2+8x+9 with a=-1 b=8 c=9
X vertex= -8/-2=4
substitute the value on the equation
Y vertex = -(4)squared+8(4)+9=25
1. is 9
and the other ones i dont really know
Answer:
4
Step-by-step explanation:
If Log a×=16diameter then value of log =4
Answer:
A
Step-by-step explanation:
You could raise 1 ^ 1000000 and the answer would still be 1.
Ogetchi is wrong.
Bernardo is right
a1 = 1
r = 8
Each term is 8 times the number before it. 8*8 = 64 ; 8*64 = 512
A
