Answer: 17 is corresponding angles, 18 is same side interior.

Step-by-step explanation:

17. I like to think corresponding angles as friends who are far away but close enough to talk. They *respond* emails to each-other! On is on the inside (x) which is like a friend being in a state, and one is on the outside (y) which is like another penpal outside of the state! Hopefully this will help you remember things better! If one is outside, and another is inside, and they aren't touching each other, then they are corresponding, like how when friends are apart and on different sides of the world! In a shorter sentence, think of it as X and Y are penpals, and the lines keep them apart but they are still connected by the transversal line (the line that crosses this way | ). The transversal line can be imagined as a telephone line, or a mail route to help you remember more.

18. Same side interior is very easy to remember and is self explanatory.

If two angles are on the inside part, they interior friends! If they are also on the same side (for y and x it's the right side) then they are same side friends! Thus them being same side interior.

Reply to me if any of these explanations don't work, I'm happy to draw an example.

Please help me in questions 15 and 21 with their inequalities and graph
aleksklad [387]

Answer:

x >= 7 OR x < -8

n <= -3 AND n > -6

Step-by-step explanation:

15) 7x - 6 >= 43 OR 10x + 4 < -76

7x >= 43 + 6 OR 10x < -76 - 4

7x >= 49 OR 10x < -80

x >= 7 OR x < -8

you can draw based on this

for >= it is full dot for < it is like circle on the graph

you have to draw both x>= 7 , x < -8 on the same line because it is OR

so both ranges of x are possible

21) 3 + 2n <= -3 AND 1 - 3n < 19

2n <= -3 -3 AND -3n < 19 - 1

2n <= -6 AND -3n < 18

n <= -3 AND 3n > -18

n <= -3 AND n > -6

so it lies between -6 and -3

Find the value of r in (4,r),(r2) so that the slope of the line containing them is -5/3 A.-1/7 B-7. C 1/7 D. 7
inessss [21]

Answer:

Option D (7).

Step-by-step explanation:

The formula for gradient of the straight line is given by:

m = (y2 - y1)/(x2 - x1); where (x1, y1) and (x2, y2) are two fixed points on the straight line. It is given that (x1, y1) = (4, r) and (x2, y2) = (r, 2). The gradient of the straight line is given by -5/3. To find the value of r, simply substitute all the values in the gradient equation. Therefore:

-5/3 = (2 - r)/(r - 4).

Cross Multiplying:

-5*(r - 4) = 3*(2 - r).

-5r + 20 = 6 - 3r.

-2r = -14.

r = 7.

Therefore, Option D is the correct answer!!!

adoni [48]

Answer:

the previous population was 62,000.

Step-by-step explanation:

The current population of a city = 83,700

The population of a city has increased by 35% since it was last measured.

We have to calculate the previous population before increasing 35%.

Let the previous population be p

p +(35% × p) = 83,700

p + 0.35p = 83,700

1.35p = 83,700

p =  

p = 62,000

Therefore, the previous population was 62,000.
