A line has a slope of -3 and a y intercept of 5. Write the equation of the line jn slope intercept form and explain how you use the slope and y intercept to graph the equation
Answer:
Slope-intercept form y = mx + b
m = slope (-3)
b = y-intercept (5)
hence, the slope-intercept form is:
y = -3x + 5
This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.

Step-by-step explanation:
Find the magnitude and direction of the vector.
<-10, 13>
Use the formula for magnitude of vector, which is [tex]m = \sqrt{a^2 + b^2}[/tex].
[tex]m = \sqrt{(-10)^2 + 13^2} = 16.401[/tex] units
In terms of direction, you can see that it is in the second quadrant because of a negative x-value and positive y-value. If you are looking for the angle of the vector, you need to use the formula,Ф = [tex]arctan(y/x)[/tex]. But because the x, value is negative, the rule is that we add π to this value.
Plug in the values:
arctan(13/-10) + π = 127.56° or 2.226 radians
Find the perimeter of the figure. Round your answer to the nearest hundredth.

Kelly sells vitamins. She made this chart to calculate her total earnings for the month of April.
Base Salary $2,500
Percent of Sales Commission 4%
What's Kelly's total earnings if she sold $6,000 worth of vitamins for April?
Answer:
2740
Step-by-step explanation:
earnings from commission is 240 (6000x.04). Her base salary 0f 2500 plus commission of 240 = 2740
There are twenty classes at each of two middle schools. The number of students in each class at each school is shown in the dot plots below.
Number of Students in Each Class at Poplar Middle School
A dot plot. A number line going from 20 to 29 labeled Number of Students. There are 3 dots above 20, 5 above 21, 7 above 22, 4 above 23, 1 above 24, and 0 above 25, 26, 27, 28, and 29.
Number of Students in Each Class at Oak Middle School
A dot plot. A number line going from 20 to 29 labeled Number of Students. There is 1 dot above 20, 2 above 21, 2 above 22, 4 above 23, 3 above 24, 2 above 25, 2 above 26, 2 above 27, 1 above 28, and 1 above 29.
Which statement correctly compares the mean number of students for the data in the plots?
There are about 2 more students in each class at Poplar Middle School than at Oak Middle School.
There are about 2 more students in each class at Oak Middle School than at Poplar Middle School.
There are about 5 more students in each class at Poplar Middle School than at Oak Middle School.
There are about 5 more students in each class at Oak Middle School than at Poplar Middle School.
The dot plot is missing, so i have attached it.
Answer:
B: there are about 2 more students in each class at Oak Middle School than at Poplar Middle School.
Step-by-step explanation:
From the dot plot attached, we can find the average number of students per class for each school.
For Poplar Middle School;
Total number of students = (20 × 3) + (21 × 5) + (22 × 7) + (23 × 4) + (24 × 1) = 435 students.
There are 20 classes.
Thus;
average number of students per class = 435/20 = 21.75
For Oak Middle School;
Total number of students = (20 × 1) + (21 × 2) + (22 × 2) + (23 × 4) + (24 × 3) + (25 × 2) + (26 × 2) + (27 × 2) + (28 × 1) + (29 × 1) = 483
Average number of students per class ; 483/20 = 24.15
Difference in average = 24.15 - 21.75 = 2.40
This implies that there are about 2 more students in each class at Oak Middle School than at Poplar Middle School.

Answer:
(2×10^8)(2×10^-2)40×10^51.2×10^9/(3×10^2)Step-by-step explanation:
Your calculator or a spreadsheet can help you do this. The rules of exponents apply.
(10^a)(10^b) = 10^(a+b)
__
(2×10^8)(2×10^-2) = 4×10^6
40×10^5 = 4×10^6
40^6 = 4.096×10^9
400,000 = 4×10^5
1.2×10^9/3×10^2 = 4×10^10 or 1.2×10^9/(3×10^2) = 4×10^6 (see note)

A woman applies a force of 300 Newtons to push a stroller 100 meters. It takes her
60 seconds to perform this work. Use the equations W = Fd and P = W x T
calculate her power.
Answer:
Work done by the woman is 500 joule per second.
Step-by-step explanation:
Force applied by the woman = 300 Newtons
Total displacement due to force = 100 meters
Work done = Force applied × Displacement due to force
= 300 × 100
= 30000 Joule
Since, Power = [tex]\frac{\text{Work done}}{\text{Time taken to perform the work}}[/tex]
= [tex]\frac{W}{t}[/tex]
= [tex]\frac{30000}{60}[/tex]
= 500 Joule per second
Therefore, work done by the woman is 500 joule per second.

What is (2x^2+ 9x + 7) = (x + 1)?
A. 2x+11
B. 7x+7
C. 2x+7
D. X+1
What is (2x² + 9x + 7) = (x + 1) ?
Solution:-2x² + 9x + 7 = x + 1
2x² + 9x - x + 7 - 1 = 0
2x² + 8x + 6 = 0
2(x² + 4x + 3) = 0
x² + 4x + 3 = 0
x² + 3x + x + 3 = 0
x( x + 3) + 1(x + 3) = 0
(x + 3)(x + 1) = 0
So, option (D) x + 1 is correct. [Answer]
