Answer:
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as "y = mx + b" and it can also be found in Tod hunter (1888) who wrote it as "y = mx + c".
Step-by-step explanation:
Steps for Graphing a Line With a Given Slope
Plot a point on the y-axis. (In the next lesson, Graphing with Slope Intercept Form, you will learn the exact point that needs to be plotted first. For right now, we are only focusing on slope.)Look at the numerator of the slope. Count the rise from the point that you plotted. If the slope is positive, count up and if the slope is negative, count down.
Look at the denominator of the slope. Count the run to the right.
Plot your point.
Repeat the above steps from your second point to plot a third point if you wish.
Draw a straight line through your points.

A circle has a diameter of 6 meters and a square with a side length of 2.4 meters. Which shape has a greater perimeter? Please show all the work.
Answer:
Circle: 18.85
Square: 9.6
The circle has a greater perimeter.
Step-by-step explanation:
The formula to calculating the circle is C=2π r
To calculate the square, just multiply 9.6x4, since a square has 4 sides.

Translate the problem into an equation and then use your equation to answer the question. Alex could arrive on time for his appointment if he leaves now and drives 50mph. However, Alex leaves the house 15 minutes earlier, drives 40mph, and arrives on time. How far from Alex's house is the appointment? need by sat.
Answer:
40 miles
Step-by-step explanation:
First, change the 15 minutes to 0.25 hours and 3 minutes to 0.05 because we are working with mph.
let x be the normal driving time to work in hours so 40x is the driving to work
since we know distance = speed multiplied by time we do
50(x-0.25+0.05)=40x
50(x-0.2)=40x
50x-10=40x
50x-40x=10
10x=10
x=1 hour normal time to work
therefore
40(1) = 40 mi to work
Confirm this by finding the dist when he went 50 mph for 48 min (0.8hrs)
50(1-.25+0.05) = 50(.8) = 40 mi also
The product of three-fourths and a number is 18. What is the number?

Kelly drinks 0.5 liters of coffee and 0.3 liters of yogurt drink at breakfast. How much did she drink in total in milliliters? (4 points)
600 milliliters.
700 milliliters.
800 milliliters.
900 milliliters.
Answer:
800
Step-by-step explanation:
Convert 0.5 liters to millimeters (0.5×1000) to get 500 ml.
Convert 0.3 liters to millimeters (0.3×1000) to get 300 ml.
Add the 2 up and you get 800 ml.

Answer:
Simplifying the expression, the answer would be [tex]81u^1^2v^8[/tex].
Process:
Basically, you just need to multiply the power on the outside with the powers on the inside of the parenthesis. Then, for the base take -3 to the fourth power which will lead you to your final answer [tex]81u^1^2v^8[/tex].
quadrilateral ABC D is the result of dilating quadrilateral ABC D about the point D buy a scale factor of 2/3
Please help i’m dumb
Answers
TrueTrueThe diagram is shown below what happens when you dilate with a scale factor 2/3, and the center of dilation is D.
Line A'B' has the same slope of AB, so the lines are parallel.
Line AD and line A'D' are the same line, since D = D'. Recall that the center of dilation does not move when applying a dilation. Point A moves to A', which is one line AD. Due to D being at the center, all lines from the center will connect the four points shown.

A construction crew has just finished building a road. The road is kilometers long. If the crew worked for days, how many kilometers of road did they build each day? (Assume they built the same amount each day.)
Write your answer as a mixed number in simplest form.
Answer:
2.1 kilometers/1 day.
Step-by-step explanation:
9 kilometers ÷ 30/7 days, which is the same as (9 x 7)/30 which is = 63/30 = 2.1 kilometers/1 day.
Answer:
2.1 km a day
Step-by-step explanation:
9 km ÷ 30/7 days, in other words (9 x 7)/30 which equals 63/30 which is 2.1 kilometers/1 day.

The number of cookies is 16 for each cup of flour used
Step-by-step explanation:
You can take numbers from the graph. For example, Number of Cookies: 192 and the Cups of flour: 12. Divide the number of cookies by the amount of flour
192÷12 = 16
Check other numbers to be sure 96÷6 = 16
288÷18 = 16
You could fill in the chart by multiplying Cups of Flour by 16 to find the number of Cookies
C = 16 × f
C = 16 × 3
C = 48
