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

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.

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.
