You have to use a system. the first would be x + y = 12 since she has 12 coins. the other equation would be 0.05x + 0.1y = 0.95 (an easier way is 5x + 10y = 95 if you clear it). now you just solve using substitution or elimination.
Answer:
4) 3.
Step-by-step explanation:
According to the graph, f(x) has been shifted two units to the right and 3 units up. k is the number of units f(x) has been shifted vertically. So, the value of K is 4) 3.
Hope this helps!
the rate of change of a linear function is the same slope
the slope of a linear function is the coefficient that accompanies the variable in this case the variable is x and the slope is -2
so, the rate of change for y is -2
Answer:
To complete $m dollars that will suffice Rebecca for her college education, she needs $(m - 60,000).
Step-by-step explanation:
Suppose Rebecca needs $m to complete her four-year college education, given that she has a yearly scholarship of $10,000, she would have $10,000 × 4 = $40,000 for the four years she would spend in college.
With her savings of $20,000, she has $20,000 + $40,000 = $60,000 in total.
To complete the required $m dollars for her college, she needs $(m - 60,000).
