Answer:
x = 8/9
Step-by-step explanation:
-4(2x-3) + 4x = 9x -4x +8 -4
2x*(-4) -3*(-4) + 4x = 9x - 4x + 8 - 4
-8x + 12 + 4x = 9x - 4x + 8 - 4 {Combine like terms}
-4x + 12 = 5x + 4
12 = 5x + 4x + 4
12 = 9x + 4
12- 4 = 9x
9x = 8
x = 8/9
Answer:
The price for each pound of tuna is not always the same.
Step-by-step explanation:
What we do is divide the price by the amount of tuna to find the price for each amount of tuna
For the 1st one, we have $8 for 2 tuna so we do 8/2
8/2 = 4
For the 2nd we have $16 for 4 so we do 16/4
16/4 = 4
For the 3rd, we have $27 for 9 so we do 27/9
27/9 = 3
A) the slope of the equation is 5, the y intercept is 10.
b) the rate of change is just the slope, so 5 but it means that they are picking 5 berries over that period of time. the initial amount is just the y intercept which is 10. this is just how many berries you start with.
c)
Answer:
Domain: (0, infinity)
Range: ( negative infinity, positive infinity)
Step-by-step explanation:
Domain is determined by the x values (left to right)
Range is determined by the y values (low to high)
