Answer:
An equation parallel to 4x + 5y = 19 would be y = -4/5x +12.
An equation perpendicular to 4x + 5y = 19 would be y = 5/4x + 10.
Step-by-step explanation:
The equation given represents a linear equation in Standard Form (Ax + By = C). Lines that are parallel to each other go the same direction and don't touch, so their slopes must be the same. However, lines that are perpendicular go in opposite directions and intersect, so their slopes must be the direct opposite of each other. In order to find the slope, you must first convert from the Standard Form given to Slope Intercept Form (y = mx +b). When you solve the given equation for 'y', you get: y = -4/5x + 19, where the slope = -4/5. To make a parallel equation, simply keep the same slope and choose a different y-intercept ('b'). To make a perpendicular equation, take the direct opposide of your slope 5/4 (positive) and choose a different y-intercept.

Hope this helps
Step-by-step explanation:
Positive Integer factors of 330 = 2, 3, 6, 5, 30, 11, 330 divided by 2, 3, 5, 11, gives no remainder. They are integers and prime numbers of 330, they are also called composite number.
Linear line formula: y = mx + b
m = slope
b = y-intercept
In this case the question gives us what we need to substitute.
m = 4
b = 3
y = 4x + 3

Answer:
It can't be factored
Step-by-step explanation:
There is no common multiple in x^2 - 7
The answer is 69. the angle is a right angle which means it is 90 degrees. subtract 90-21 to get 69
