Find the slope of each line.

у
To find the slope of a line, remember:
[tex]slope=\frac{rise}{run}[/tex].
Also, the points that you choose to use to calculate your rise and your run must meet at an exact point, not in the middle of a block. In your graphs the points are the little blue dots, so that's already been done for you and that's what we'll use to calculate the slope!
Also, recall that the rise is how many blocks the line has changed vertically (so is one point lower/higher than another point)
The run is how many blocks the line has changed horizontally (so how many blocks over is the next point)
Therefore, for #1 we can see that the point on the right is over 3 blocks (run), and it goes down 1 block (rise).
So for #1, your answer is: [tex]slope=\frac{rise}{run}=\frac{-1}{3}[/tex] or [tex]-\frac{1}{3}[/tex]
For #2 we see that one point is higher by 3 blocks (rise) and it also goes over one block (run)
So, your answer to #2 is: [tex]slope=\frac{rise}{run}=\frac{3}{1}=3[/tex]
Hope this helps! :)
A frog leaps off of a ledge and lands on the ground below. The function
f(x) = -1.6x2 + 2.3x + 3.2 represents the frog's path.
a. How high is the ledge where the frog starts?
b. How high is the frog at its highest point?
c. What is the frog's horizontal distance from the ledge when it
reaches its highest point?
Answer:
-1.6x2 + 2.3x + 3.2 = f(x) to solve this you do -1.6 x 2 = -3.2 + 2.3x = -0.9 + 3.2 = 2.3
Step-by-step explanation:
For A the height of ledge is 3.2
for b - the frogs highest point 2.30x
and c is 12.3x

Find the value of x
solving steps
Answer:
x = 8
Step-by-step explanation:
Supplementary angles add up to 180 degrees to make a straight line.
The red square in one of them indicates that it is 90 degrees on their side which means that it is 90 degrees on the other where (6x+2) and 40 degrees are.
(6x+2) + 40 = 90
6x + 42 = 90
6x = 48
x = 8
what type of mathematical law is this (6+4)+100=6+(4+100)
Answer:
Associative Property of Addition
Step-by-step explanation:
According to the Associative Property of Addition: when three real numbers are added, it makes no difference which two are added first.
a + (b + c) = (a + b) + c
Therefore, in the given equality statement: (6 + 4) + 100 = 6 + (4 + 100), the sum of the numbers on either side of the equation will have the same results.
(6 + 4) + 100 = 6 + (4 + 100)
(10) + 100 = 6 + (104)
110 = 110

Below are two parallel lines with a third line intersecting them 107
Answer:
x° = 107°
Step-by-step explanation:
Given that m < 107° and m < x° are alternate interior angles that do not have a common vertex on alternate sides of the transversal, then it means that they have the same measure. It also implies that their supplements will have the same measure, 73°.
Therefore, x° = 107°.

At the Richard's pound the ratio of cats to dogs is 9 to 6. If there are 45 cats in the pound then
how many dogs are in the pound?
Answer:
30 dogs are in the pound.
Step-by-step explanation:
If the original ratio is 9:6
Then multiply both sides by 5: (9*5) : (6*5)
New ratio: 45:30

Kylee is making a cake. The box says for every 1/4 cup of water she needs to use 2/4 of the cake mixture. She uses 3 1/4 cups of water. How much cake mixture does she use? (show your answer as a decimal and as a fraction.)
Answer:
Kylee makes 6 1/2, or 6.5 cups of the cake mixture.
Step-by-step explanation:
She uses double the cake mixture as water. She uses 3 1/4 cups of water, or 13/4 as an improper fraction, so she uses double that of cake mixture, which is 6 1/2, or 26/4 cups of cake mixture.
As a decimal that is 6.5.

If
f(x) = x - 5
and
g(x) = 4x – 2
-
Find
f(g(x)) = 4x – [?]
-
Answer:
4x - 7
Step-by-step explanation:
To evaluate f(g(x)) substitute x = g(x) into f(x)
f(g(x)
= f(4x - 2)
= 4x - 2 - 5
= 4x - 7
f(x) =2x+1 g(x)= x^2 -7 find (f+g)(x)
Answer:
[tex]f(x) = 2x + 1 \\ g(x) = {x}^{2} - 7 \\ (f + g)(x) = f(x) + g(x) \\ (f + g)(x) = (2x + 1) + ( {x}^{2} - 7) \\ (f + g)(x) = 2x + 1 + {x}^{2} - 7 \\ \boxed{ (f + g)(x) = {x}^{2} + 2x - 6}[/tex]
(f+g)(x) = x²+2x-6 is the right answer.Round each number to the nearest thousand.

Recall that the perimeter of a rectangle is P=2(W+L), where W is the width and L is the length. The length of a rectangle is 23 feet more than the width. If the perimeter is 70 feet, then what is the length of the rectangle, in feet?
Answer:
Length = 6 + 23 = 29 feet
Step-by-step explanation:
Width = x
Length = x + 23
2x + 2(x+23) = 70
2x + 2x + 46 = 70
4x = 70-46
x = 24/4
x = 6
Determine the coordinates of A(2,3) after a reflection in the line y=2
Answer:
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection)
Peter is calculating the interest earned on a deposit of $275 in an account that earns 8% simple interest after 12 years. I = prt I = 275(.8)(12) I = 2,640 a. What did Peter do incorrectly? b. What is the correct amount of interest I NEED HELP.
Answer:
What Peter did wrong was that he should have multiplied 275 by 0.08 and 12, not 0.8 and 12. The correct amount of interest he will earn is $264.

Answer:
x=22
Step-by-step explanation:
From the theorem of Z angles you can find that the sum of both given angles must equal 180.
So solve: 2x-26 + 7x+8 = 180
Simplify:
9x -18 = 180
9x = 198
x = 198/9 = 22
Given f(x) = x^2+9x+18 and g(x)=x+6
Find f(x)-g(x)
Answer:
x = -6, -2
Step-by-step explanation:
x^2 + 9x + 18 - (x + 6)
x^2 + 9x + 18 -x - 6
x^2 + 8x + 12
(x+6)(x+2)
x = -6, -2
