Answer:
undefined
Step-by-step explanation:
The slope of a line given two points is given by
m = (y2-y1)/(x2-x1)
= (9-6)/(5-5)
= 3/0
This slope is undefined
Answer:
Hi
Step-by-step explanation:
in this formula
d is diameter
v is circumference
because the question asked the answer in terms of pi so we write the pi its self
hope this help you
god bless you and us
Answer:
The parallel line would be y = -x - 6
Step-by-step explanation:
In order to find the parallel line, we must first start with the slope. The slope of parallel lines must be equal. The first line has a slope of -1. Using this and the new point in slope intercept form, we can solve for the intercept.
y = mx + b
2 = -1(-8) + b
2 = 8 + b
-6 = b
Now we can model the equation using that slope and the intercept.
y = -x - 6
Answer:
26%
Step-by-step explanation:
Adding r% to a bill is equivalent to multiplying the amount by (1 +r%). Each resulting amount is rounded to the nearest penny.
__
<h3>tax</h3>
After the 6.5% tax was added, the bill was ...
$12.70 × (1 +0.065) = $13.5255 ≈ $13.53
<h3>tip</h3>
After the 18% tip was added to this amount, the total cost was ...
$13.53 × (1 +0.18) = $15.9654 ≈ $15.97
<h3>total</h3>
Then the multiplier of the original bill was ...
$15.97/$12.70 ≈ 1.25748... ≈ (1 +25.7%)
The total cost was about 26% more than the original bill.
When solving equations like these, our number one goal is to get x to be alone.
So given the equation lets go through it step by step.
3x - 5 = 10 + 7x (first step is to add 5 to both sides)
+ 5 = + 5 ( Now lets see what we have now)
3x = 15 + 7x ( We need the x to be alone! So lets subtract -7x from both sides.)
-7x = -7x ( now what do we have?)
-4x = 15 (okay divide both sides by 4 to isolate the x)
÷4 = ÷4 (now the 4's on the left side cancel out, and we solve on the right side)
x = 3.75
That's your answer :) Good Luck!
