y = 4x - 5 and (3,4) (7, 3) A. parallel B. perpendicular D. neither
Answers
Answer:
The lines are perpendicular. Option B.
Explanation:
Equation of the Line
One of the characteristics of the line is its slope. It can be determined in two ways:
* From the equation y=mx+b, the m is the slope. The given equation is y=4x-5. Thus, the slope of this line is m=4.
* Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The points are (3,4) and (7,3), thus the slope is:
[tex]\displaystyle m=\frac{3-4}{7-3}=-\frac{1}{4}[/tex]
A. For two lines to be parallel, their slopes must be equal. Since m1=4 and m2=-1/4, the lines are not parallel. Incorrect
B. For two lines to be perpendicular, their slopes must meet the condition:
[tex]m1*m2=-1[/tex]
4*(-1/4)=-1
Both lines are perpendicular. Correct choice
D. Since choice B. is correct, this cannot be true. Incorrect

It’s E. 64%
Step-by-step explanation:
Based on the number of people who had a car and the total number of people surveyed, the percentage is E. 64%
Percentage of those with carsThe percentage of students with a car is:
= Number of students with cars / Number of students in total x 100%
Solving gives:
= 60 / 94 x 100%
= 63.8%

What is the unitary method?The unitary technique entails finding the value by multiplying the single value and then solving the problem using the initial value of a single unit. If an event may take place in m different ways and a second event can take place in n different ways after it, then the two events that follow can take place in m n different ways.
Given,
time spend for homework is
4/5 hours = 4/5×60 = 0.8×60 = 48 minutes
if 1/2 of this time is spent on working science homework
48×1/2= 48×0.5= 24 minutes
Hence, the total minutes spent, working on science homework is 24 minutes.

Christine bakes 20 cookies every half hour. Charlie sells 38 cookies per hour. How many cookies are left unsold if they work from 6:00 AM until noon?
Answers
Answer:
12
Step-by-step explanation:
The number of cookies that are left unsold if they work from 6:00 AM until noon is 12.
Cookies baked per hour by Christine = 20*2 =40
Cookies sold per hour by Charlie = 38
How many hours will be there between 6:00 AM and noon?There will be 6 hours between 6:00 AM and noon.
So, Cookies baked by Christine in 6 hours = 40*6 =240
Cookies sold by Charlie in 6 hours = 38*6 =228
Number of unsold cookies =240-228 =12
Hence, the number of cookies that are left unsold if they work from 6:00 AM until noon is 12.

**either can come first, it just depends which comes first in the equation.

The simplified answers is -22.
What is order of operation?The order of Operations is the rule in math that states we evaluate the parentheses/brackets first, the exponents/the orders second, division or multiplication third (from left to right, whichever comes first), and the addition or subtraction at the last (from left to right, whichever comes first). In math, there might be several operations to be done while evaluating an expression, and simplification at the end yields different results. However, we can only have one correct answer for any sort of expression. To identify the correct answer we simplify any given mathematical expression using a certain set of rules. These rules revolve around all the basic operators used in maths. Operators such as addition (+), subtraction (-), division (÷), and multiplication (×).
The order of operation can be termed as BODMAS.

What is the slope of the line?
Answers
The points represented by the table lie on a line, then the slope of the line would be; 3.
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
Its slope would be:
[tex]m = \dfrac{y-q}{x-p}[/tex]
Since the Slope of parallel lines is the same. Slopes of perpendicular lines are negative reciprocals of each other.
Using any two pairs from the table of values given which are; (-4, 2) and (-3, 5):
[tex]m = \dfrac{y-q}{x-p}[/tex]
Now Plug the value into the slope formula:
m = (5 - (-4))/ (5 - 2)
m = 9/3
m = 3
Therefore, the slope of the line would be; 3.
