Answer:
{12, 16}
Step-by-step explanation:
The difference of two <em>numbers (x and y)</em> is 4. Thus, if y is the larger, then y - x = 4. Also, y = 2x - 8.
So we need to solve the system of linear equations
y - x = 4
y = 2x - 8
Subbing 2x - 8 for y, in the first equation, we get (2x - 8) - x = 4, or
x - 8 = 4, and conclude that x = 12. Then, because y - x = 4, y must be 16.
The numbers are 12 and 16.
Answer:
Rate of change is slope
To calculate slope its
y2 - y1 / x2- x1 = slope
Just choose 2 random sets from the table.
I’m gonna go with (0,-10) and (2,20)
Now calculate slope
20 - (-10) / 2 - 0
Solve.
30 / 2
30/2 = 15
Rate of change is 15
Answer:
0.03 more flour per cupcake
Step-by-step explanation:
3.12/8 = 0.39
2.52/7 = 0.36
0.39 - 0.36 = 0.03
