Let her score on her math test be y and the number of hours a week that she plays video games be x,
y = k/x
73.6 = k/10
k = 736
y = 736/x
y = 736/8
y = 92
She can expect a score of 92 on her math test if she plays video games for only 8 hours a week.
Step-by-step explanation:
total sold = 136
hot dogs sold : soda - 30
136 = soda + hot dogs
136 = soda + (soda -30)
136 = 2soda -30
2soda = 166
soda sold = 83
hot dogs sold = 83-30 = 53
Answer:
Slope = 4
y-intercept = -3
Step-by-step explanation:
A slope describe the steepness of a graph, which can also be referred to as gradient. The general equation of a linear graph is given as:
y = mx ± c
where: m represents the slope of the graph and c the intercept on the required axis.
Given: y = 4x - 3
Comparing this equation with the general equation of a linear graph, it can be observed that; the slope is 4, while the intercept on the y axis is -3.
Thus,
slope = 4
intercept on the y axis = -3
Answer:
Step-by-step explanation:
You didn't list the options from which we are to choose as your system of inequalities, but that doesn't matter...we'll come up with them on our own and then you can match them to your options. The first inequality is going to be about the number of hours worked. The second inequality is going to be about the money earned. Hours worked and money earned have to be in 2 different inequalities because they are not the same. If x is one job and y is the other, and the combination of these jobs cannot be more than 12 hours total, then the inequality for this is:
x + y ≤ 12
That represents the hours worked. As far as the money goes, she makes $8 per hour, x, at the first job, and $9 per hour, y, at the second job. She wants the combination of these wages to be at least $100. The inequality that represents the money earned is:
8x + 9y ≥ 100
That is the system that represents your situation.
