6) Use the subtraction property to complete the statement: If AB+12=DC+12, then AB = Your answer
Answer:
AB = DC
Step-by-step explanation:
[tex]AB+12=DC+12~(Given)\\\\AB+12-12=DC+12-12~(Subtract~12~on~both~sides)\\\\AB=DC~(Simplify)[/tex]
Answer:
AB = DC
Step-by-step explanation:
AB + 12 = DC + 12
To find AB, we can subtract 12 from both sides (this leaves AB on its own):
AB + 12 - 12 = DC + 12 - 12 (Now, we can simplify)AB = DCHope this helps!

Does the parabola open up or down? How do you know? (2pts)
What is the maximum or minimum value? How do you know? (2pts)
What are the x-intercepts? (2pts)
What is the y-intercept? (1pt)
What is the vertex? (2pt)
9514 1404 393
Answer:
a) a=1, b=4, c=-5
b) opens up; a > 0
c) minimum = -9, the y-value of the vertex
d) x = -5, 1
e) y = -5, the value of c
f) (-2, -9)
Step-by-step explanation:
A graph drawn by a graphing calculator can answer all of these questions quickly and easily.
__
a) The values of 'a', 'b', and 'c' are the values of the coefficients of the terms in the function definition. They refer to the coefficients in the standard form:
f(x) = ax^2 +bx +c
f(x) = x^2 +4x -5 . . . . . . . your equation with a=1, b=4, c=-5
__
b) The parabola opens up. This is because the value of 'a' is greater than zero.
__
c) The minimum is the y-value of the vertex. When the function is written in vertex form it is ...
f(x) = (x -h)^2 +k . . . . . . . . . . . vertex (h, k)
Your function can be put into this form:
f(x) = x^2 + 4x +4 -5 -4 . . . . . . add and subtract 4 to complete the square
f(x) = (x +2)^2 -9 . . . . . . . . vertex form. The vertex is (-2, -9).
The y-value of the vertex is -9, the minimum value of the function.
__
d) Solving f(x) = 0, you get ...
(x +2)^2 -9 = 0
(x +2)^2 = 9 . . . . . . . . add 9
x +2 = ±√9 = ±3 . . . . . take the square root; next, subtract 2
x = -2 ±3 = {-5, 1} . . . . . the x-intercepts
__
e) The y-intercept is f(0) = c = -5.
__
f) The vertex was found in part (c) to be (-2, -9).

Did you mention that multiplication is a shortcut for repeated addition?
Step-by-step explanation:
yes, in a similar way as division is a shortcut for repeated subtraction.
you do know, that you normally have to add the points win in a game, right ?
so, your score grows by 200 points each time you score.
that means
200
200
200
...
200
what do you think you do to get the total ? you add all the points.
you don't multiply them, because e.h 200×200 would be the shortcut of adding 200 for 200 times.
but you did not have 200 hits, you only got 12 hits.
so, you either do the effort of adding 200 12 times, or you simply multiply 200 by 12 (as this is the mentioned shortcut).
and you don't just add 12 to 200. that would give you only 212. and you did not earn 12 points to add. you earned 12 times 200 points to add.
that is how multiplication works and helps with additions.

Answer:
x = 11
Step-by-step explanation:
180°( n - 2 ) ÷ n
~~~~~~~~~~
( 7x + 31)° = 180°( 5 - 2 ) ÷ 5
7x + 31 = 108
7x = 77
x = 11
What are the slope and y-intercept of the line? Question 2 options:
Slope = 6, y-Intercept = 170
Slope = -170, y-Intercept = 1020
Slope = 1020, y-Intercept = -170
Slope = 170, y-Intercept = 6
Answer: SLOPE=-170, Y-INTERCEPT = 1020
Step-by-step explanation:
Calculate the slope: Take any two points and find the changes in x and y:
I'll use (4, 340) and (6, 0):
Change in y (the rise) is (0 - 340) = -340.
The change in x is (6-4) = 2
The slope is the rise (y) over the run (x): -340/2 or -170.
The y-intercept is the value of y when x=0. The f=-data provided has a value for y at x=0: (0,1020). So the interecpt is 1020.

Explain why the square root of a number is defined to be equal to that number to the 1/2 power.
This is because of the law of indices which says:
[tex]\sqrt[x]{n}[/tex]= [tex]x^{\frac{1}{m} }[/tex]
So, if we have:
[tex]\sqrt{n}[/tex]
Then the following will be true because of this math law:
[tex]n^{\frac{1}{2} }[/tex]
Side note: The m value can be greater than n and or less than n, but if it is equal the m and n values cancel out.

How many ways are there to arrange 1,2,3,4,5 in a line, such that n is not in the nth position?
For Example: 2,1,3,4,5 is not valid because 3 is the 3rd in the line but 2,1,4,5,3 is valid because none of the numbers are in their original position.
Answer:
256 ways
Step-by-step explanation:
Okay so n cannot be in the nth place, but there are 5 places available.
So thinking about it technically you can have 4 of each number in a different spot not their own, and 4x4x4x4 = 256
However, if that doesn't work, you could try 4! which is 4x3x2x1 = 24

A line passes through the point (-6, -2) and has a slope of -5/2
Answer: y = -5/2 -17
Step-by-step explanation: First put the equation in point slope form
Y-y1 = m(x-x1)
y + 2 = -5/2(x+6) then simplify to slope int. form
Y= mx + b
Y = -5/2x-17
Answer:
y = (-5/2)x - 17
Step-by-step explanation:
Slope Intercept Formula:y = mx + b
m = slope
b = y-intercept
Plugin Information:
y = mx + b
Slope = -5/2
y = (-5/2)x + b [tex]\longmapsto\\[/tex] Input x and y values from given point
-2 = (-5/2)-6 + b
Simplify, Solve for b:-2 = (-5 * -6)/(2) + b
-2 = 30/2 + b
-2 = 15 + b
b = -2 - 15
b = -17
Rewrite Equation:y = mx + b
m = -5/2
b = -17
y = (-5/2)x - 17

A hot air balloon is 200.6 feet above land. After 5 minutes, the parasail is at 120.8 feet above land. What is the change in height?
Answer:
-79.8
Step-by-step explanation:
The change can be found by subracting the ending distance from the beginning distance.
In this case, its 200.6-120.8= 79.8
It is negative because the distance in the end became lower than the beginning distance.
Hope this helps!
