Answer:y=0
Step-by-step explanation:
slope=(y2 - y1) ➗ (x2 - x1)
1/2=(y-2) ➗ (3-7)
1/2=(y-2) ➗ -4
Cross multiplying we get
-4=2(y-2)
-4=2y-4
Collect like terms
-4+4=2y
0=2y
y=0
D/2=r
12/2=6
a=pir^2
a=pi6^2
a=36pi
a=113.04
3rd option again
Yesss that's what I think
Step-by-step explanation:
Let us move everything to the one side with y by itself to make it easier. the first equation we don't have to change. y=2x+12 and the second equation becomes -y=-2x-12 and we can divide both sides by negative to get rid of the negative on y so it becomes y=2x+12. So they are the same thing.
Answer:
At the restaurant you only have $30 to spend on dinner.
=> 8% sales tax is applied in your bill.
=> And need to leave a 20% tip.
Now, let’s find out how much will be the most expensive item you can order
Let us solve for the 8% tax first
=> 30 dollars * 8%
=> 30 dollars *.08 = 2.4 dollars
Then let’s solve the 20% tip
=> 30 dollars * .20 = 6 dollars
Solve
=> 2.4 + 6.00 = 8.4 dollars
=> 30 dollars – 8.4 dollars = 21.6 dollars
Thus, you can only spend around 22 dollars to be able not to exceed at your 30 dollars budget.
