3 to the power of 5 to the power of 2-3 to the power of 0 is 9 because 3 to the power of 0 is one and 2 minus one is one and 2 to the power of one is two and 3 to the power of 2 is 9
Answer:
Rate of change/slope: 35
Miles at 10 hours: 350
Step-by-step explanation:
We can find the rate of change or the slope by using the slope formula below:
m = (y2-y1)/(x2-x1) where m is the slope
To find the slope, we can choose any two points from the table. I will choose (2,70) and (4,140)
m = (140-70)/(4-2)
m = 70/2
m = 35
The rate of change is 35 miles per hour
To find the miles at 10 hours, we can use the equation y = mx + b which is the equation of the line in slope intercept form. However, we will need to find the value of b. To do that, we can plug in any point from the table to find the value of b. I'll choose (2,70).
y = mx + b
70 = 35(2) + b
70 = 70 + b
b = 0
So the equation of the line would be y = 35x. Using this equation, we can find the number of miles at 10 hours:
y = 35(10)
y = 350
The number of miles at 10 hours is 350 miles
First we must define variables:
x: number of Snickers candy bars
y: number of KitKat bars
We write the system of equations:
27.50x + 21.50y = 119.50
48x + 36y = 204
Solving the system we have:
x = 2 packages
y = 3 packages
Answer:
she did buy:
2 packages of Snickers candy bars
3 packages of KitKat bars
Answer:
36 inches but im really not sure though because you got to times them together and then divide by 2
