No
Both share the same x-values which means it isn’t a function
Hope this helps ;)
Answer:
48
Step-by-step explanation:
2 x 2 x 2 x 2 = 16
16 + ?
4 x 4 x 4 = 64
0.5 x 64 = 32
32 + 16 = 48
Answer:
42.6cm
Step-by-step explanation:
The sum total of all the sides of the shape is the perimeter of the shape. Hence;
Perimeter = x+3 + 4 + x+9 + 2x+5
Perimeter = 4x + 21
Given
Area of the figure = 75cm^2
Area = (x+3)(2x+5) + (2x+1)(6)
75 = 2x²+5x+6x+15+12x+6
75 = 2x²+23x+21
2x²+23x+21-75 = 0
2x²+23x-54 = 0
x = -23±√23²-4(2)(-75)/4
x = -23±√529+600/4
x = -12±√1129/4
x = -12+33.6/4
x = 21.6/4
x = 5.4
Recall that;
Perimeter = 4x+21
Perimeter = 4(5.4) + 21
Perimeter = 21.6+21
Perimeter = 42.6cm
Hence the perimeter is 42.6cm
X is always dependant to Y. so that should answer the 1st one. the 2nd looks to be around 17-18. 17.5 maybe. and the 3rd is yes cause he does not go to the pool so it isnt any cost.
Answer:
10%
Step-by-step explanation:
First, 97.90-89=8.90
8.90/89 = x/100
8.90 x 100 = 890
890/89=10%
Check Answer:
89 x 10%=8.90
89+8.90= 97.90
Therefore, the sales tax percentage is 10%
