30 points!!!!!!!!!!!!!!!!!!!!!!! Help ASAP!!! 1.) Line a passes through points (-2, 1) and (2, 9). Write an equation in slope intercept form that is parallel to line a.
Step 1: Use slope formula* to determine slope (or m) using both points given.
[tex]\frac{9 - 1}{2 - (-2)}\\\\\frac{8}{4} = 2[/tex]
Step 2: Use slope-intercept formula** , ONE of the points given, and the slope we just found to solve for b.
[tex]1 = 2(-2) + b\\\\1 = -4 + b\\\\5 = b[/tex]
Step 3: Now we can set up an equation of this line in slope-intercept form.
[tex]y = 2x + 5[/tex]
*Slope formula: y₂ - y₁/x₂ - x₁
**Slope-intercept formula: y = mx + b
Answer:
The slope calculator helps find the slope of any line through two given points. ... To find the equation of a line for any given two points that this line passes through, use our ... to calculate the slope of the line passing through the points (3,8) and (-2, 10) . ... Make sure that the points you measure from are the same as step 1.

Kiran's mother gets a restaurant bill for $25. She has a coupon for 15%. After the discount is applied, she adds 20% as a tip. What is the total after the discount and tip? (don't forget the $)
Answer:
$25.50
Step-by-step explanation:
So we have a 15% off coupon. We can multiply 25×.85 to find our new price.
Our total is now $21.25
Now to find the tip do $21.25 +(.2 × 21.25)
*The .2 is 20 percent of our discount price.*
We then get $25.50

Ethan goes to a store an buys an item that costs xx dollars. He has a coupon for 5% off, and then a 9% tax is added to the discounted price. Write an expression in terms of xx that represents the total amount that Ethan paid at the register.
Answer:
Final Cost= 1.09(xx - .05xx)
Step-by-step explanation:
Since its 9% tax on the new price you would take the new price which would be 1.0 and add the .09 of tax. So its ×1.09 to get the tax.
The expression for the total cost is 1.09(xx-(0.05)xx).
What is total cost?The total cost is the amount calculated after any discount for an item and along with the tax incurred for an item to be purchased.
For the given situation,
Ethan buys an item that costs xx dollars.
He has discount coupon of 5% = 0.05
The tax percentage is 9% = 0.09
The discounted amount will get less from the cost price. So,
⇒ [tex]xx-(0.05)xx[/tex]
The tax amount for the item will get added to the final cost of an item. Thus the expression becomes,
⇒ [tex]1.09(xx-(0.05)xx)[/tex]
Hence we can conclude that the expression for the total cost is 1.09(xx-(0.05)xx).

Answer: 14:00
Step-by-step explanation:
We have to add to the initial time the times that are consumed with each activity:
First time: 7:00
7hours 0 minutes
Three surgeries x two hours = 6 hours
7hours 0 minutes + 6 hours = 13hours 0 minutes
He drives 30 minutes
13 hours 0 minutes + 30 minutes = 13hours 30 minutes
He eats a snack 30 minutes
13hours 30 minutes + 30 minutes = 13 hours 60 minutes = 14hours 0 minutes
