What is the slope of the line passing through the points (4, 5) and (0, -7)? Show all your work.
Answer:
slope = 3
Step-by-step explanation:
calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, 5 ) and (x₂, y₂ ) = (0, - 7 )
m = [tex]\frac{-7-5}{0-4}[/tex] = [tex]\frac{-12}{-4}[/tex] = 3
rise over run
you can also use the y2-y1/x2-x1 but these numbers where small enough where graphing can help visually

P ( not blue )SolvinG :
- First step is to find out P( blue )
P ( blue ) = 3 / 12 = 1/4- Now , find out P ( not blue )
P ( not blue ) = 1 - 1/4 = 3/4- Option D [ 3/4 ] is the right option.

Answers: 585, 587, and 593
Basically everything except 599
==============================================================
Why?
Those answers in bold are closer to 590 than they are to 580 or 600. When rounding to the nearest ten (not tenth) we look at the units digit. If it is 5 or larger, then we bump the tens digit up by 1 and replace the units digit with a 0.
This explains why 585 and 587 round to 590
The number 599 rounds to 600 for similar reasoning, but we cross it off the list since we want 590.
The number 593 rounds to 590 because the 3 in the units digit isn't 5 or larger. So we just replace the 3 with 0 and keep everything else as is.

Which expression can be used to find 532 divided by 4?
A: (500 divided by 4)+(30 divided by 4)
B: (500 divided by 4)+(32 divided by 4)
C: (500 divided by 4)+(30 divided by 4)+2
D: (500 divided by 4)+(32 divided by 4)+2
C: (500 divided by 4)+(30 divided by 4)+2
Expanded form or expanded notation is a way of writing numbers to see the math value of individual digits. When numbers are separated into individual place values and decimal places they can also form a mathematical expression. 532 ÷ 4 in expanded notation form is (500 divided by 4)+(30 divided by 4)+2

Identify the five key values of each store’s prices.
Compare the two box plots.
Answer:
1. unknow
2. mean median range spread average
3. the bike Ville is more expensive in everything
Using Average, the prices of bicycles at two stores are compared.
What is average?Average is the" sum of observations divided by total number of observations".
According to the question,
The price of bicycles at two stores are shown.
Bikeville: 140 160 800 235 250 450 80 115 220 250 96 290
Discount Bicycles: 50 180 300 110 120 150 155 285 120 200 70 175 95
Average of bikeville = [tex]\frac{sum of observations}{Total number of observation}[/tex]
= 140 + 160 + 800 + 235 + 250 + 450 + 80 + 115 + 220+250+96+29
= 3086
Average of bikeville= 3086/12
= 257.167
Average of Discount of bicycles:
( 50 +180+100+110+120+150+155+285+
120+150+155+285+120+200+70+175+95) =2720
= 2720/15
=181.33
Average of Discount of bicycles is 181.33.
Hence, using Average the prices of bicycles at two stores are compared.

How are the two functions f(x) = 0. 7(6)x and g(x) = 0. 7(6)–x related to each other? g(x) is the reflection of f(x) over the x-axis. G(x) is the reflection of f(x) over the y-axis. G(x) is the reflection of f(x) over both axes. G(x) and f(x) will appear to be the same function.

Step-by-step explanation:
Each side of the cube is 7 mm.
First, find the area of one face. The formula for the area of a square is [tex]s^2[/tex]. 7 mm squared is 49 square millimeters.
A cube has 6 faces, so multiply the area of one face by 6. 49*6 = 294 square millimeters

years?
A) $7,962.65 B) $8,625.82
C) $8,287.61 D) $7,650.44
Answer:
$7650.44
Step-by-step explanation:
Annual interest rate = 4.02%
but compound 4 times per year, means quarterly compound
quarterly interest rate = 4.02%/4 = 1.005%
Account balance = 4734 * (1.01005)^48 [compound 4 times a year for 12 years]

5) Find the x-intercept and the y-intercept of the equation: 8x - y = -24.
Answer:
First we have to turn it into slope intercept form which is y = mx + b.
we need to isolate y. To do this, we have to subtract 8x from both sides to get
-y = -8x - 24
-25 is the y intercept and -8 is the slope.

Janay cut a drinking straw into three pieces (shown below) to investigate a triangle postulate. He moves the straw pieces to make triangles that have been translated, rotated, and reflected from an original position. The end of one piece is always touching the end of another piece. Which postulate could Zhan be investigating using only these straw pieces and no other tools?
Answer:
B. If three sides of one triangle are congruent to three sides of a second triangle then, the triangles are congruent.
