there u go thats quick maths
The association between the given lines is that they are 'neither perpendicular nor parallel.'
To prove, let's convert the given equations in their slope-intercept form i.e. 'y = mx + b'
-7x + 2y = 3
2y = 7x + 3
y = 7/2x + 3/2
-6x + 3y = 2
3y = 6x + 2
y = 2x + 2/3
This shows that both the lines have different slopes, as well as, intercepts of y. And,
= 2 * 7/2 ≠ -1
Thus, it is not perpendicular also.
Therefore, <u>option D</u> i.e. 'neither perpendicular nor parallel' is the correct answer.

Answer:
22 miles
Step-by-step explanation:
Given data
A towing company charges $50 plus $4 per mile
let the number of miles be x
the expression for the charges for x miles y is given as
y= 50+4x
for y= 138
138= 50+4x
138-50= 4x
88= 4x
x= 88/4
x= 22 miles
Hence the distance is 22 miles
Answer:
For the 1st question (4) For the 2nd question (1)
Step-by-step explanation:
(4) because 15000x+10000y needs to be less than or equal to 20000 or else they're going over the budget but x+y needs to be less than or equal to 15 as they can't make more than that.
(1) Divide both sides by pi and h then square root both sides.
Answer:
sin∅ = 0.7311
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
sin∅ = opposite/hypotenuse
Step 1: Find our hypotenuse
14² + 15² = c²
c = √421
Step 2: Find sin∅
sin∅ = 15/√421
sin∅ = 0.731055
