Answer:
C. The relationship between the quantities is: add 25.
Step-by-step explanation:
1x = 25y,
2x = 25 + 25 = 50y
3x = 50 + 25 = 75y
4x = 75 + 25 = 100y
Note:
As you can see, every time the number goes up on the chart, it goes up by 25 and you can find that out by just simply adding 25 to the first number and seeing if it matches up with the next, (which I did above).

Consider the following 8 numbers, where one labelled x is unknown.
41, 13, 15, X, 46, 46, 23, 12
Given that the range of the numbers is 53,
Answer:
X = 65.
Step-by-step explanation:
The range is the greatest number - least, so we have:
X - 12 = 53
X = 53 + 12 = 65.
Answer:
I think x=65

Choice D is not the correct answer. Point L is equally distant from J and K. In other words, JL = LK. If two friends lived at points J and K, then point L would be a good meeting spot as they would travel the same distance. Point N has the same properties as point L does (with regard to being equally distant from J and K). It is not correct to say that LJ = JN.
The answer is actually choice C. Segments JL and KL need to be constructed using a straightedge.
Otherwise, these segments are not going to be shown and you cannot use them. A segment is simply a straight line between two endpoints. Two triangles form (triangle JNL and KNL) to help with the proof, so it's very beneficial to draw in these segments. It might help to use a different color pen, or lightly draw the segment using a faint pencil mark to erase later.

Solve for a and b. please help.
Answer:
a= 22.5
b= 37.5
Step-by-step explanation:
In △BCD:
Applying Pythagoras' Theorem,
a² +30²= b²
a² +900= b² -----(1)
In △ABC:
Applying Pythagoras' Theorem,
b² +50²= (40 +a)² -----(2)
Substitute (1) into (2):
a² +900 +50²= 40² +2(40)(a) +a² (expand bracket)
a² +900 +2500= 1600 +80a +a²
a² +3400= a² +80a +1600 (simplify)
a² +3400 -a² -80a -1600= 0 (bring everything to 1 side)
-80a +1800= 0
80a= 1800 (+80 on both sides)
a= 1800 ÷80
a= 22.5
Subst. a= 22.5 into (1):
22.5² +900= b²
b²= 506.25 +900
b²= 1406.25
b= √1406.25 (square root both sides)
b= 37.5 (reject negative value since b is a length)
☆(a +b)²= a² +2ab +b²
Maya is 14 years old. Her brother Jorge is 3 years more than half her age. Which of the following is the correct expression for Jorge's age?
The correct expression for Jorge's age is (14 ÷ 2) + 3
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, Maya is 14 years old. Her brother Jorge is 3 years more than half her age.
We need to determine an expression for Jorge's age,
So, If you divide her age by two and add 3 then you will get Jorge age and that is what the question is asking,
i.e. (14 ÷ 2) + 3
Hence, the correct expression for Jorge's age is (14 ÷ 2) + 3

Sara bought a computer that was originally priced at $896. The computer was on sale for 12% off. When she bought the computer, a 7% tax was added to the sale price. How much did Sara spend on the computer?
(Round to the nearest cent)
Answer:
$843.67
Step-by-step explanation:
1. Calculate the discount that was taken off from the original price.
$896 x 12% = $107.52
2. Subtract the discount taken off from the original price. This gives you the total paid AFTER the discount was taken.
$896-$107.52= $788.48
3. Calculate the tax amount by multiplying the discount price by the tax rate.
$788.48 x 7% = $55.19
4. Add the tax amount back to the discount price.
$788.48 + $55.19 = $843.67

Solve |x+4|=6 need help for a quiz
Answer:
down below
Step-by-step explanation:
set up two equations:
x + 4 = 6 x + 4 = -6
solve both:
x = 2 x = -10
plug it back in to the original equation:
|2 + 4| = 6. |-10 + 4| = -6
|6| = 6. |-6| = -6
6 = 6. since absolute value is always positive:
correct. |6| = -6
6 does not = -6
write both of these down if you need to show your work

9514 1404 393
Answer:
a) y = (x -4)² -4
b) (4, -4)
c) translated 4 right, 4 down
Step-by-step explanation:
a) Apparently "graphing form" is a reference to "vertex form." That form is ...
y = a(x -h)² +k . . . . . . parabola with vertex (h, k) and vertical scale factor 'a'
The coefficient of x² in your given equation is 1, so a=1. The values of h and k can be found as follows.
'h' is the opposite of half the x-coefficient in your equation, so is h = -(-8/2) = 4. The value of k is the square of h, subtracted from the constant in your equation: k = 12 -h² = 12 -16 = -4. (This applies when a=1, as here.) These calculations are the "cut to the chase" version of "completing the square."
The method of "completing the square" has you consider the x-terms separately from the constant term:
y = (x² -8x) +12
To "complete the square", you want to make the terms in parentheses be a perfect square trinomial. You do that by adding the square of half the x-coefficient. In order to keep the same equation, you need to subtract an equivalent amount outside parentheses:
y = (x² -8x +(-8/2)²) +12 -(-8/2)² . . . . . add and subtract (-8/2)²
y = (x -4)² +(12 -16)
Then the vertex form is ...
y = (x -4)² -4 . . . . and the vertex is (h, k) = (4, -4).
The graphing calculator plot attached confirms this vertex value.
__
The problem statement tells you that you can also find this form by averaging the x-intercepts. If you factor your equation, you get ...
y = (x -6)(x -2)
The x-values that make these factors zero {6, 2} are the x-intercepts. Their average (6+2)/2 = 4 is the x-coordinate of the vertex (h). You can find the y-coordinate of the vertex by evaluating y when x=4: y = 4² -8·4 +12 = -4. So, the vertex by this method is (h, k) = (4, -4), and the equation in graphing form is ...
y = (x -4)² -4 . . . . as above.
__
b) As we saw above, the vertex coordinates are (h, k) = (4, -4).
__
c) The vertical scale factor 'a' is 1, so the only transformation done on the graph is to move the parent vertex (0, 0) to the location (4, -4). That is, the graph has been translated 4 units right and 4 units down. (In the attached, the parent function is shown with a dashed line.)
