Answer:
Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form: where m is the slope (also called the gradient) and b is the y-intercept (the value of y when x is 0)
<u>1) Plug the gradient into the equation (b)</u>
We're given that the gradient of the line is 4. Plug this into as m:
<u>2) Determine the y-intercept (b)</u>
Plug in the given point (1,10) as (x,y) and solve for b
Subtract 4 from both sides to isolate b
Therefore, the y-intercept of the line is 6. Plug this back into as b:
I hope this helps!
Step-by-step explanation:
8x-9=5x-3
Move any equation to the opposite side. I'll use the left this time
move 6 to opp side
For quarters we have:
Where,
x: number of quarters
Clearing x we have:
For nickels we have:
Where,
y: number of nickels
Clearing y we have:
Then, the ratio of quarters to nickels is:
Simplifying we have:
Answer:
The ratio of quarters to nickels in a dollar is:
