Answer: Violet has 5 dimes and 15 quarters.
Step-by-step explanation:
let x denotes the number of dimes and y denotes the number of quarters.
Given : Violet has $4.25 worth of dimes and quarters .
Also, 1 dime = $0.1
1 quarter = $0.25
i.e. (1)
She has 3 times as many quarters as dimes.
i.e (2)
Substitute the value of y in equation (1) , we get
Divide both sides by 0.85 , we get
Substitute the value of x in (2) , we get
Hence, Violet has 5 dimes and 15 quarters.
(10 cents/ 1 ft)($1/ 100 cents)=
10/ 100= $0.1 per foot or $1 per 10 ft
Answer:
1. Plot the point (–2,4).
2. From that point, count left 3 units and down 1 unit and plot a second point.
3. Draw a line through the two points.
Step-by-step explanation:
Given:
The equation is:
Express this in the standard form,
Where, is the slope of the line and is the y-intercept.
So, the slope is and y-intercept is .
Now, for
So, first we plot the point .
Since, the slope is , we have to move 3 units to left and then 1 unit down to plot a second point.
Slope is positive, therefore, we have to move left and then down
Lastly, we have to draw a line passing through these two points to graph the equation .
The answer is 50! Rate of change= y1-y2/x1-x2
