This question is asking about UNIT RATE - which is the same thing as SLOPE or RATE OF CHANGE. The easiest way to solve this is to find "for 1..." BUT IF YOU FORGET TO DO THAT, THE BEST THING TO DO IS...

add all of the numbers together

If you are not sure what to do, the best thing to do is...

plug the numbers into desmos and make sure the fractions are equal to eachother

choose the one that matches the numbers on the graph

On maps like this, the big idea is that to be a function...

each x value should only have one path to a y value

each y value should only have one path coming to it from an x value

One way you could solve this is to find the SLOPE from the table using y2-y1/x2-x1... BUT If you forget that, you could...

Choose an x (in this case, a p) value, plug it into the equation, and see if it gives you the total charge that matches it in the table

Choose a y (in this case, a c) value, plug it into the equation, and see if it gives you the people that matches it in the table

See if the table is increasing or decreasing

when you see the words DIRECT VARIATION, that means the relationship is PROPORTIONAL... so you could....

set up a proportion, then cross multiple and divide to find the missing y

in a PROPORTIONAL RELATIONSHIP...

there is MULTIPLICATION ONLY, no addition or subtraction

there is ADDITION/SUBTRACTION ONLY, no multiplication

there is a multiplier and then something being added/subtracted

What is the best way to find the SLOPE from a picture?

where the line crosses the y axis

where the line crosses the x axis

What is the easiest way to solve this problem if you are not sure what to do?

choose a # of months from the table, plug it into the situation, and see if the number of cards you would have matches the table

Select the following that are true about proportional relationships

Multiplication ONLY, so every x should be multiplied by the same thing to get y

On a graph line has to be straight

On a graph line has to be going through the origin

to solve this problem.....

choose an x, multiply it by 3, take away 8, and see if it matches the y in the table

choose an x, take away 8, multiply it by 3, and see if it matches the y in the table

choose an x, add 8, multiply it by 3, and see if it matches the y in the table

choose an x, multiply it by 3, add 8, and see if it matches the y in the table

The easiest way to solve word problems that are matching an equation is to find your MULTIPLIER first. In this problem...

45 is being multiplied by the number of months, so it should be 45m

45 is being multiplied by the number of months, so it should be 45t

he is paying his dad $23 so it should be 23m

he is paying his dad $23 and then $45 each month, so it should be 68m

This problem WANTS you to set up an equation (35.75m+75=17.95m+164) and then solve for m... BUT If you don't know how to solve it, what would be the best choice?

Choose a # of months, plug it into each situation, and see which # of months would give you the same cost for both gyms

The total will never be the same because they are two different situations

Choose the answer choice in the middle

The easiest way to solve word problems that are matching an equation is to find your MULTIPLIER first. In this problem...

30 is a multiplier so 30x should be with 6.25, and 12 is a multiplier so 12x should be with 9.75

6.25 is a multiplier so 6.25x should be with 30, and 9.75 is a multiplier so 9.75x should be with 12

The easiest way to solve this problem is to....

find the multipliers and the numbers that go with them, and see if the answer choice matches

see which answer choices have the same numbers

plug in an x and see if it gives you the same number for both situations

solve for x by getting the variable by itself

This question WANTS you to set 2.3x+25=5.8x+11 and solve for x by getting x by itself... BUT if you forget to do that, you could _______

plug in the x value in the answer choice into both 2.3x+25 and 5.8x+11 and see which one would give you the same answer for both

Add 25+11 and then divide by 2.3 and 5.8

Select the following that are true:

Those are both ACUTE (little) angles

One angle is ACUTE (little) the other is OBTUSE (big)

The angles add up to 180 degrees

The angles add up to 360 degrees

What is true about all of the angles inside a triangle?

They add up to 180, so 7x+2+8x+4x+7=180

They add up to 90, so 7x+2+8x+4x+7=90

The two big ones equal the little one, so 4x+7+8x=7x+2

They are all equal, so 7x+2=8x=4x+7

Select the following that are true:

One angle is ACUTE (little) and the other is OBTUSE (big)

The two angles add up to 180, so 13x+12+2x+3=180

Those are both ACUTE (little) angles

The two angles are equal, so 13x+12=2x+3

The two angles add up to 90, so 13x+12+2x+3=90

What is true about the angles of similar shapes (angles inside of the same shape but one shape is big and one is small)

The CORRESPONDING (matching) angles in similar shapes must be CONGRUENT (equal)

The CORRESPONDING (matching) angles in similar shapes must be PROPORTIONAL (set up as proportion and cross multiply/divide)

Two corresponding angles must equal 180 together

In this question YOU DON'T EVEN NEED MOST OF THE ANSWER CHOICE!!! You only have to find angle A! :) There is a trick to solve this, but if you don't remember...

Find the missing angle INSIDE the triangle first, because once I find it I know that number taken away from 180 (because it is on a line together) will give me angle A

Add 38 and 50 and take it away from 180

DILATIONS have a rule where x and y are...

multiplied (if by a # smaller than 1, it would shrink - greater than 1 it would grow)

multiplied (if by a # larger than 1, it would shrink - smaller than 1 it would grow)

don't forget to SUBTRACT Jack & Greta's distances at the end!

use pyth theorem to find ave f and you are done!

don't forget to ADD Jack & Greta's distances at the end!

don't forget to DIVIDE Jack & Greta's distances at the end!

INCREASING means getting bigger, so this question wants you to order these from LEAST to GREATEST.
What do you need to be careful of in this question?

The bigger the negative, the lesser the value - so the bigger negative will come first

The bigger the negative, the lesser the value - so the smaller negative will come first

Because it is L->G, the percent would come first because it is less than 1

The biggest negative should be last because it is a greater value
