This table represents the altitude change in meters, m, as a hiker hikes down a mountain in h hours.
When graphed, all of the points in the table lie on the same line.
What is the slope and y-intercept of the line?
Drag and drop the slope and y-intercept into the corresponding boxes.
Hours, h Altitude in meters, m
0 1020
2 680
4 340
6 0
Slope y-intercept
CHOOSE WHICH GOES IN THE SLOPE AND THE Y-INTERCEPT
-170, 6, 170, 1020
Answer:
slope: -170
y-int: 1020
P.S. I made sure my answer was right by graphing the equation (y = -170x + 1020) on a calculator :)

Answer:
a. 4x^2 +16x -48 = 4x^2 +16x -48
b. -3x^2 +12x +36 = -3x^2 +12x +36
c. x^2 +12x +35 = x^2 +12x +35
Step-by-step explanation:
In general, you would prove this by transforming one of the expressions into the other. The easiest would be to transform the factored form into the vertex form, perhaps, as this would spare you trying to explain the magic of factoring.
Alternatively, you can transform both expressions into the same (standard) form. I believe that will be the easiest of all.
The product of two binomials is ...
(x +a)(x +b) = x(x +b) +a(x +b) = x^2 +bx +ax +ab
(x +a)(x +b) = x^2 +(a+b)x +ab . . . . after collecting terms
The square of a binomial is the same thing, but with b=a, so ...
(x +a)^2 = x^2 +2a +a^2
Using these forms, we can avoid showing all of the intermediate "work" of making the desired transformations.
__
a. 4(x -2)(x +6) = 4(x +2)^2 -64
4(x^2 +4x -12) = 4(x^2 +4x +4) -64 . . . . . expanding the products
4x^2 +16x -48 = 4x^2 +16x +16 -64 . . . . using the distributive property
4x^2 +16x -48 = 4x^2 +16x -48 . . . . . collect terms; expressions are equal
__
b. -3(x +2)(x -6) = -3(x -2)^2 +48
-3(x^2 -4x -12) = -3(x^2 -4x +4) +48
-3x^2 +12x +36 = -3x^2 +12x -12 +48
-3x^2 +12x +36 = -3x^2 +12x +36
__
c. (x +5)(x +7) = (x +6)^2 -1
x^2 +12x +35 = x^2 +12x +36 -1
x^2 +12x +35 = x^2 +12x +35
Answer:
A. 3 and 1/3 (Fraction), B. Has infinite answer (I think. I may have this wrong), and C. 0.
Step-by-step explanation:
A. We have the equation 4(x-2)(4+6)= 4(x+2)^2 - 64.
1. (4x-8)(10)=(4x+8)^2 - 64 (We have to use PEMDAS, so the P goes first).
2.(4x-8)(10)= 16x +64 - 64 (Then we use E next.)
3. 40x-80 = 16x (Again with the P)
4. 40x = 16x +80 (Add 80 to both sides. And you might have drop the PEMDAS Here I think).
5. 24x = 80 (We subtract 16x from both sides)
6. x = 3 and 1/3 (Divide both sides by 24.
B. We have the equation: -3(x+2)(x-6)=-3(x-2)^2+48
1. Times the -3.
(-3x-6)(x-6)=(-3x-6)^2 +48
2. Times the exponent
(-3x-6)(x-6)=9x+36+48
3. Times the the ones that are in the braces the first using FOIL and add the other on the other side of the equation.
-3x^2 + 12x +36= 9x+84
4. Subtract 9x and 36 from both sides
-3x^2 +3x= 48
This may have an infinite answer to this, and I don't know if I'm wrong on this.
C. (x+5)(x+7)= (x +6)^2 -1
1. Times the exponent
(x+5)(x+7) = x^2 + 36 -1
2. Times the ones in the braces using FOIL.
x^2+7x+5x+35=X^2+36-1
3. Add all of the like Terms.
x^2+12x+35=x^2+35
4. Subtract x^2 from both sides (I may did this wrong)
12x + 35 = 35
5. Subtract 35 from both sides.
12x = 0
6. Divide both sides by 12 (I may have this wrong too)
x=0
And that's it. I may have some things wrong, but it's worth a shot.

Step-by-step explanation:
It is because 3n = 3 x n. If a number is in parentheses and there is no operation to the right, it means multiplication ALWAYS. So, 3n + 10 = 3 x n + 10

Is there enough information to prove that the triangles are congruent? If yes, provide the correct Triangle Congruence Postulate or Theorem and a congruence statement If no, justify your answer.
Answer:
Yes, there is (ASA)
Step-by-step explanation:
Here, we have a side common to the two triangles. That makes S
Also, we can see an angle on both triangles, that makes A
Lastly, there is a right angle on both triangle
That makes another A
So we have the ASA to prove the congruence of the two triangles

PLEASE HELP!! DUE SOON :( #40
Answer:
Types of polygon
Polygons can be regular or irregular. If the angles are all equal and all the sides are equal length it is a regular polygon.
Regular and irregular polygons
Interior angles of polygons
To find the sum of interior angles in a polygon divide the polygon into triangles.
Irregular pentagons
The sum of interior angles in a triangle is 180°. To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°.
Example
Calculate the sum of interior angles in a pentagon.
A pentagon contains 3 triangles. The sum of the interior angles is:
180 * 3 = 540
The number of triangles in each polygon is two less than the number of sides.
The formula for calculating the sum of interior angles is:
(n - 2) * 180 (where n is the number of sides)
how to find the factors of 82
Answer:
Step-by-step explanation:
What is 82 dividend by 3 and keep dividing intill you cant any more and you got your answer
Answer:
To find factors, you can either divide 82 by each number from 1 to 10 (which seems to work most of the time, but if it doesn't continue onward with the numbers), or you could see what, when multiplied, equals 82. But remember these must not be decimals or fractions.
The factors are 1, 2, 41, 82

Step-by-step explanation:
To solve for [tex]r[/tex]:
[tex]v=\frac{4}{3}r^{3}[/tex] (given)
[tex]\frac{3v}{4}=r^{3}[/tex] (times [tex]\frac{3}{4}[/tex] on both sides)

of black cars to red cars at 8:3. If the get a
shipment of 24 black cars, how many red cars can they expect?
cars can they expect?
Answer
13 2/9
