Answer:
56
Step-by-step explanation:
16 x 3 = 48
Half of 16 is 8
48 + 8 = 56
Answer:

Step-by-step explanation:
Answer:
The best approximation for the input value when f(x) = g(x) is x = 1.5.
Step-by-step explanation:
The function f(x) passes through the points (-3,1) and (0,1) and the point (1.5,1).
Therefore, the line has equation y = 1.
Now, the function g(x) passes through the points (0,-1), (1.5,1) and (3,3) points.
Therefore, the function g(x) crosses the line y = 1 at the point (1.5,1).
Hence, the best approximation for the input value when f(x) = g(x) is x = 1.5. (Answer)
4. y=4x-7 ---- first equation
y=2x+9 ---- second equation
substitude first equation into second equation
4x- 7 = 2x + 9
2x = 16
x = 8 --- third equation
substitude third equation into first equation
y = 4(8) - 7
y = 25
5. 8x+2y=-2 ---- second equation
y=-5x+1 ---- first equation
substitude first equation into second equation
8x + 2(-5x+1) = - 2
8x - 10x + 2 = - 2
2x = 4
x = 2 ---- third equation
substitude third equation into first equation
y = - 5(2) + 1
y = - 9
6. y+2x=-1 ---- second equation
y-3x=-16
y = 3x - 16 ---- first equation
substitude first equation into second equation
3x - 16 + 2x = - 1
5x = 15
x = 3 --- third equation
substitude third equation into first equation
y + 2(3) = - 1
y = - 7
Answer: 35
Step-by-step explanation:
Let x be the number of hats and y be the number of shirts.
Cost of each hat = $15
Cost of x hat = 15x
Cost of each shirt = $14
Cost of y shirt = 14y
Total shirt sold = 72
Combined selling price = $1,043.00
According to the given question , we have the following system of equations :
Multiply 14 on both sides of equation (1) ,we get
Eliminate equation (3) from equation (2) , we get
Hence, he sold 35 hats.
