Answer: Xavier bought 2 apples and 9 bananas.
Step-by-step explanation:
Let x represent the number of apples that Javier bought.
Let y represent the number of bananas that Javier bought.
At the store, he bought $6 worth of apples and bananas. Each apple costs $0.75 and each banana costs $0.50. This is expressed as
0.75x + 0.5y = 6 - - - - - - - - - - - - 1
He bought a total of 11 apples and bananas altogether. This means that
x + y = 11
Substituting x = 11 - y into equation 1, it becomes
0.75(11 - y) + 0.5y = 6
8.25 - 0.75y + 0.5y = 6
- 0.75y + 0.5y = 6 - 8.25
- 0.25y = - 2.25
y = - 2.25/ - 0.25
y = 9
x = 11 - y = 11 - 9
x = 2
Perpendicular angle so the slope is the opposite reciprocal: 1/6

plug in x and y values of given point

find b
b = - 5
rewrite equation with b and slope values

Step-by-step explanation:
The dependent variable is the number of times you have typed. This is because time is the independent (x) variable as the number of times you've typed is the dependent (y) variable.
