She did not divide 28 by7
The x-axis shows the independent variable and the y-axis shows the dependent variable. so therefore the x-axis will be the years and the y-axis will be the subscribers. hope this helped!
D because there’s a pattern. Pattern for x is that it’s adding by one. Pattern for y is that it’s adding by 15
Answer:i think you have to equal them to each other
Step-by-step explanation:
Answer is: 32 nickels and 23 dimes.
<span>x - number of nickels .
y -number of dimes.
two equations in two unknowns:
1) x + y = 55
2) 0,05x + 0,1y = 3,90.
</span>nickel is a five-cent coin.
dime is a ten-cent coin.<span>
solve equation 1) for x and substitute for x in equation 2)
x = 55 - y
0,05</span>·(55 - y) + 0,1y = 3,90<span>2,75 - 0,05y + 0,1y = 3,90
0,05y = 1,15
y = 23.
x = 55 - 23 = 32.</span>
