Answer:
x=4 y=4
Step-by-step explanation:
When a line and a curve are tangent to each other, they are joined together by 1 point (x,y). So, you equate both equations either in terms of x or y. For this problem, let's equate in terms of y.
y = k - x
y = x² + 3x + 1
k - x = x² + 3x + 1
k = x² + 3x + x + 1
k = x² + 4x + 1
This would be the value of k. Since we are not given the common point, it can only be expressed in terms of x or y.
1,3,5 because they are all negatives less than -3
Answer:
$323
Step-by-step explanation:
The monthly payment can be calculated using the formula:
where:
- M=monthly payment
- P=amount borrowed
- r=annual interest rate
- n=total number of monthly payments:
Our parameters are defined as:
We plug our parameters in the equation to solve for M;
Hence, the monthly payment is $323
Answer:
D) The slope of the line is undefined
Step-by-step explanation:
A vertical line will have an undefined slope, because it does not run horizontally.
To find the slope, you calculate it with rise over run, however, a vertical line will not run horizontally, meaning the run is 0.
And, dividing anything by 0 will get you an undefined answer.
So, D is correct. the slope of the line is undefined
