Conditions for Lines to be parallel
If two straight lines are cut by a transversal, the pair of alternate angles are equal, then two straight lines are parallel to each other. the pair of interior angles on the same side of traversals is supplementary, then the two straight lines are parallel.
Given line
3y – 2x = – 2
passes through (3, –3)
The slope-intercept form is
y =mx+b,
where m is the slope and
b is the y-intercept.
y = mx+b

Reorder terms.
y = -(2/3)(x+1)
Using the slope-intercept form, the slope is

To prepare one bowl of salad, 3 3/4 pounds of vegetables are required. How many pounds of vegetables are required to prepare one-third bowl of salad?
Applying the knowledge of fractions, the number of pounds of vegetables required to prepare 1/3 bowl of salad is: 1¼ pounds.
How to Solve Fractions?In solving this problem, we would apply our knowledge of fractions as explained below.
One bowl of salad needs 3¾ pounds of vegetables
Let the number of pounds if vegetables needed for ⅓ bowl be represented as x. Therefore, we would have the following proportion:
1 bowl = 15/4 pounds of vegetables [i.e. 3¾]
⅓ bowl = x
Thus:
1/15/4 = ⅓/x
1/1 × 4/15 = 1/3 × 1/x
4/15 = 1/3x
Cross multiply
4(3x) = 1(15)
12x = 15
Divide both sides by 12
12x/12 = 15/12
x = 15/12
x = 5/4
x = 1¼ pounds
Therefore, applying the knowledge of fractions, the number of pounds of vegetables required to prepare 1/3 bowl of salad is: 1¼ pounds.

With Plan B, you can pay 19 cents per minute plus a flat fee of $6.00. This can be represented by the equation c = 0.19m + 6.00
Complete the following steps to determine how many minutes you would need to use for
Plan B to be less expensive than Plan A
Write an inequality that represents Plan B < Plan A
Inequality: ____ <_____
Solve the inequality and use your answer to complete the following sentence:
Plan B is less expensive than Plan A when you use at least ______
Plan B is less expensive than Plan A when you use at least 25
What is an inequality?Inequalities can simply be defined as mathematical expressions in which both or two sides of the expression are not equal.
From the information given, we have that;
Plan A = c = 0. 25mPlan B = c = 0. 19m + 6. 00Now, let's write the inequality that represents Plan B < Plan A
If Plan B < Plan A
Then,
0. 19m + 6. 00 < 0. 25m
Let's simply the inequality

In an arithmetic progression (AP) sequence of numbers, the difference between any two consecutive integers is always the same. It is also known as an arithmetic sequence.
There are two definitions for an arithmetic sequence. Each term in an arithmetic sequence is created by adding a predetermined number (positive, negative, or zero) to its preceding term. It is a "series where the differences between every two following terms are the same."
Given,
first term, a = 7
common difference d = 7
n = 2
a+(n-1)d = 7+( 2 - 1 )7
= 7 + 7
= 14
n = 3
a+(n-1)d = 7+(3-1) 7
= 7+14

There are 713 identical plastic chips number one through 713 in a box what is the probability of reaching into the box and randomly drawing the chip number to 564 express your answer as a simplified fraction or decimal rounded to four decimal places
The probability of randomly drawing the chip number 564 is 1 / 713 or 0.0014
What is the probability?
Probability is used to determine the odds that a random event would happen. The odds that the event would happen is a distribution that lies between 0 and 1.
If it is certain that the event would occur, the probability value would be 1. If it is certain that the event would not occur, the probability value would be 0. If it is equally likely that the event would happen or not happen, the probability value would be 0.5.
The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.
The probability of randomly drawing the chip number 564 = number of chips numbered 564 / total number of chips

Since m(n(x)) = n(m(x)) = x, then m(x) and n(x) are inverse functions
What is the inverse of a function?The inverse of a function is a function that can reverse into another function.
If we have function f and g, and f f(x) = y, then g is the inverse of f if and only if g(y) = x
Also, if f is a function f⁻¹ is the inverse of x and ff⁻¹(x) = f⁻¹f(x) = x
How to show that the composite fucntions are inverses?Given the functions m(x) = x³ - 5 and n(x) = ∛(x + 5)
If m(x) and n(x) are inverse, then m(n(x)) = n(m(x)) = x
So, we proceed as follows
m(x) = x³ - 5
m(n(x)) = (∛(x + 5))³ - 5
m(n(x)) = x + 5 - 5
m(n(x)) = x + 0
m(n(x)) = x
Also,
n(x) = ∛(x + 5)
n(m(x)) = ∛(x³ - 5 + 5)
n(m(x)) = ∛(x³ - 0)
n(m(x)) = ∛(x³)
n(m(x)) = x
Since m(n(x)) = n(m(x)) = x, then m(x) and n(x) are inverse functions

Based on the money earned by Kaleigh's aunt from Wheels Around Town, the relationship between miles and money earned is proportional.
How to find a proportional relationship?In a proportional relationship, the rate of increase or decrease in x should be equivalent to the rate of increase or decrease in y. This rate should be constant through the entire distribution.
The equation of the line should take the form:
y = mx
There should be no y-intercept.
The slope is:
= (48 - 72) / (120 - 180)
= -24 / - 60
= 2/5
Every value of y has to be 2/5 of x.
= 160 x 2/5 = 64
= 200 x 2/5 = 80
The relationship is therefore proportional.
