The factory produce 11 shirt in half minute (30 seconds)
100x12= (10x12)+(10x12)+(10x12)+(10x12)+(10x12)+(10x12)+(10x12)+(10x12)+(10x12)+(10X12)= 700
Answer:
1) Slope: 3; y-intercept: -7
2) Slope: 2/3; y-intercept: 1
Step-by-step explanation:
y = mx + b; m is slope and b is y-intercept
1. y = 3x - 7
The equation is already in slope-intercept form, so you can find the slope and intercept.
Slope: 3
y-intercept: -7
2. y - 1 = 2/3x
For this one, you have to convert this into slope-intercept form (solving for y)
y - 1 = 2/3x
Add 1 to both sides
y - 1 + 1 = 2/3x + 1
y = 2/3x + 1
Now that the equation is in slope-intercept form, you can get the slope and y-intercept.
Slope: 2/3
y-intercept: 1
A.
y = 20(1.15)^x.....parrots
y = 4x + 24.....snakes
B. after 10 yrs
y = 20(1.15^10)
y = 20(4.05)
y = 81 parrots
y = 4(10) + 24
y = 40 + 24
y = 64 snakes
C.
20(1.15)^x = 4x + 24
x = 6.63 years they will be the same
The answer to your question is H I know this because I did the math on a sheet of paper
