hi help pls will mark as brainlist!!!!!!!!!​

Lets find the slope of the graph for Jennifer's record.  THe slope represents her rate.

Slope = (y2 - y1) / (x2 - x1)

 Lets use the first two points.

 Slope = (8 - 5) / 64 - 40)

         = 3 / 24

         = 1 / 8

Use the second and third points.

 Slope = (10 - 8) / (80 - 64)

        = 2 / 16

        = 1 / 8

Last points.

 Slope = (12 - 10) / (96 - 80)

        = 2 / 16

        = 1 / 8

 The slopes are constant.  

 Now we compare the slopes.  Use the LCD to compare fractions.  

1 / 9 = 8 / 72

 1 / 8 = 9 / 72

 9 / 72 > 8 / 72

 Jennifer has the faster training rate.  She can cover more distance in less time than Patrick can.

31/2

Step-by-step explanation:

yes

answer: 50°

If triangle is isosceles than L and J are same angles

3x + 20 = 4x + 10

3x-4x=10-20

-x = -10 (divide both sides by -1)

x=10

angle L=J = 3*10+20= 50

we can calculate it like this too 4*10 +10= 50

Answer: 705 cm

Step-by-step explanation:

Ron and Hermione are lifting feathers into the air with magic. Hermione can lift a feather 3,525

centimeters (cm) into the air. That is 5 times as high as Ron can lift a feather.

How high can Ron lift a feather with his magic?

Hermione = 3,525 cm

Hermione = 5 × Ron

Substitute Hermione = 3,525 cm into

Hermione = 5 × Ron

3,525 = 5 × Ron

Ron = 3,525 / 5

= 705

Ron = 705 cm

Step-by-step explanation:

Kiran atttended 18 parent-teacher conferences and 18 school-related assemblies.

Let x represent the number of parent-teacher conference and y represent the school-related assembly.

Since Kiran earns $1008 for 36 paid events, hence:

x + y = 36    (1)

34x + 22y = 1008    (2)

Solving equations 1 and 2 simultaneously gives:

x = 18, y = 18

Therefore Kiran atttended 18 parent-teacher conferences and 18 school-related assemblies.

Answer:

Solution is (3, -3)

Step-by-step explanation:

To solve by graphing, you literally have to graph both lines to see where they intersect. That point of intersection is the solution to the given system.

Given the following linear equations:

y = - x   where the slope (m) = -1, and the y-intercept (b) = 0.

y = x - 6 where the slope (m) = 1, and the y-intercept (b) = -6.

Plot the intercepts (0, 0) for the first line, and (0, -6) for the second line, as a starting point, then use the given slopes (rise over run) of each line to plot the next points. Repeat the process until you have enough points to connect with and create a line.

Attached is a screenshot of the graphed systems of linear equations. It shows that the solution is (3, -3).

Answer:

It's not proportional

Step-by-step explanation:

The first 2 days are proportional because, they travel at an increment of 60 miles an hour.

But, on the third day, it is not proportional because they travel at an increment of 90 miles an hour.

360 / 4 = 90

120 / 2 = 60

60 / 1 = 60

Answer:

The answer would be yes and no!! But, it would be no!

Step-by-step Explanation:

Yes: On Monday and Tuesday, those would be proportional because they are just counting by 60´s. 60 plus 60 would give you 120.

No: On Wednesday, this ¨person¨ traveled 360 miles in 3 hours. Now, you aren´t counting by 60´s anymore. Even though you started out counting by the 60´s, doesn´t mean you will finish like that.

60´s:

1 hour = 60 mi

2 hours = 120 mi

3 hours should be = 180 miles, not 360 Because:

360 mi would be equal to 6 hours. Do you see where I´m going with this?

Hope that helps you so you can put it in a mathematical way. Have a great day!!

If you get it wrong, plz notify me any way possible...... :)

m<1(exterior angle) = (sum of two opposite interior angle) 50+70 = 120°.

hope this helps you.

Answer:

120 degrees

Step-by-step explanation:

50 + 70 = 120

180 - 120 = 60

180 - 60 = 120 degrees

Answer:

formula: (y_2-y_1)/(x_2-x_1)

slope: 0

Step-by-step explanation:

1. The formula to find the slope given two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].

2. (Solving)

Therefore, the slope is 0.

Answer:
