Answer:
slope is 1 and y-intercept is (0,-5)
Step-by-step explanation:
Question 1:
For this case, the first thing we must do is define variables.
We have then:
x: number of nickels
y: number of dimes
We write the system of equations that adapts to the problem.
We have then:
0.05x + 0.10y = 6.10
x + y = 67
Solving the system we have:
x = 12
y = 55
Answer:
there are 12 nickels
Question 2:
For this case, the first thing we must do is define variables.
We have then:
x: Allan's score
y: Dave's score
We write the system of equations that adapts to the problem.
We have then:
x + y = 375
x = 2y-60
Solving the system we have:
x = 230
y = 145
Answer:
Dave: 145 Allan: 230

Step-by-step explanation:
(5300 + 1335.6) = 5300(1 + 0.07)^n where n is the number of years required
6635.6 = 5300(1.07)^n
(1.07)^n = 1.252
n log 1.07 = log 1.252
n = log 1.252 / log 1.07 = 3.32 years Answer
So what is your question?
