im confused on the bottom circle answer its a bit weird it reads "a. (use algebra) Use the diagram at the right. What algebraic expression represents GK?
b. if GK = 30, what are GH and JK?"
Answers
Step-by-step explanation:
well you need to add the right expressions for the shorter lines so that there is no overlap. otherwise GK would be too long.
so, how can we combine the 3 red lines to get exactly GK ?
we cannot just add 2 of these lines. the results would always be either too long or too short.
but we see "2x + 3" overlaps a bit with "4x - 3". and hey, the third line "x" is just the length of the overlap of the other 2 lines.
so, we can add the first 2 lines, IF we reduce first one of them by the overlap length.
I picked the second line.
so, we have
2x + 3 - x + 4x - 3 = GK
5x = GK
so, "5x" is the algebraic expression representing GK.
now, if GK = 30, then we know
5x = 30
x = 6
GH = 2x + 3 - x (again, we need to shorten that line by the overlap length to count only to H)
= 2×6 + 3 - 6 = 6 + 3 = 9
JK = GK - GJ = 30 - (2x + 3) (here we need the full line, as we are dealing with J)
= 30 - 2×6 - 3 = 15

Yes, the set of points is a function.

A function only passes through any given y value once. None of the y values (the second number in the form (x, y)) are the same, so the set of points is indeed a function.

4. Is it appropriate to use an absolute value inequality to represent how a player wins
this game? Why? (2 points: 1 point for an answer, 1 point for an explanation)
Answers
Using it's concept for the difference between points, the absolute value inequality |x - y| < 10 represents when Erik wins the game, and the inequality |x - y| ≥ 10 represents when Nina wins the game.
What is the missing information?Erik and Nita are playing a game with numbers. In the game, they each think of a random number from zero to 20. If the difference between their two numbers is less than 10, then Erik wins. If the difference between their two numbers to greater than 10, then Nita wins. Use what you know about inequalities and absolute values to better understand the game.
What is the absolute value function?The absolute function is defined by:
|x| = x, x ≥ 0.|x| = -x, x < 0.It measures the distance of a point x to the origin, hence, for example, |-2| = |2| = 0.
For this problem, we have that:
Erik's number is x.Nina's number is y.The difference between these two numbers is:
|x - y|.
Erik wins if the difference is less than 10, hence:
|x - y| < 10.
Hence:
Using it's concept for the difference between points, the absolute value inequality |x - y| < 10 represents when Erik wins the game, and the inequality |x - y| ≥ 10 represents when Nina wins the game.

An artist is making a scale model of a statue. On the model 2 inches represents 1 foot on the actual statue. Which graph best represents this relationship?
Answers
Answer:
Step-by-step explanation:
Just so you can see it easier, 4 inches = 2 feet.
That means you should pick graph C
What my first statement means is that you have to pick some point on the graph that translates to (say) 4 inches to 2 feet. Since that point is clear on graph C, that's what you choose.
A doesn't make that same ratio. It goes 1 to 1. That is 4 inches = 4 feet. That's not the correct ratio
B is 10 inches to 2 feet. That is no where's near the right answer. Just plot the points I'm choosing to see if the ratio holds.
D is 4 inches to 21 feet. Obviously not 2 to 1.
Answer:
C

As the model size increases by 2, the statue size increases by 1

Answer:

Step-by-step explanation:
First of all it's not that you aren't very good at math it's just that you don't YET understand the concepts,... Believe me when I say that I've been there!!!
To solve this problem you have to look at it as a solve for the unknown problem,... They say that The FORMULA (important) is the following:
S = Ar
This can be written:
S = A * r
They then say that
S = sales tax,
A = cost of the product
r = local sales-tax rate,...
THEN they start giving you information,... they say the COST of a television (cost of the product) is $400 dollars you can now enter this info in you formula,... A = cost of product,... so switch the letter with the assigned info,...
S = $400 * r
...and the sales tax is $24 dollars,... S stands for sales tax so switch the variable for the dollar amount,...
$24 = $400 * r
Now you just have to solve the equation (figure out $400 * what = $24) and easy way to do this is to simply divide $24 by $400,...
$24/$400=0.06,...
0.06 = 6.0% = 6.00%

Find the measure of unknown angle
Answers
Answer:
Step-by-step explanation:
z = 102 degree (opposite angles of a parallelogram are equal)
z + x + 34 = 180 degree 9sum of adjacent angles of a parallelogram is 180 degree)
102 + x + 34 = 180
x = 180 - 136
x = 44 degree
y + 102 + x = 180 degree (sum of interior angles of a triangle is 180 degree)
y + 102 + 44 = 180
y = 180 - 146
y = 34 degree
Answer:
x = 44°, y = 34°, z = 102°
Step-by-step explanation:
The opposite angles of a parallelogram are congruent , then
∠ z = 102°
Consecutive angles are supplementary , then
x + 34° + 102° = 180°
x + 136° = 180° ( subtract 136° from both sides )
x = 44°
∠ y = 34° ( alternate angle
