Find a point-slope equation of the line having the given slope and containing the given point.
m=−6; (6,4)
Answers
Answer:
[tex]\boxed {y - 4 = -6(x - 6)}[/tex]
Step-by-step explanation:
Since you already have the given slope and the given point, use the Point-Slope Formula to make it a Point-Slope Form:
[tex]y - y_{1} = m(x - x_{1})[/tex]
Slope: [tex]m[/tex]
First Point: [tex](x_{1}, y_{1})[/tex]
-Substitute both the given slope and the given point:
Slope: [tex]-6[/tex]
First Point: [tex](6,4)[/tex]
[tex]\boxed {y - 4 = -6(x - 6)}[/tex] (Substituted in Point-Slope Form)
Answer:
y-4 = -6(x-6)
Step-by-step explanation:
Pre-SolvingGivenWe are given that a line has a slope of -6 and a point of (6, 4).
We want to find the equation of this line in point-slope form.
FormulasPoint-slope form is given as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point.
SolvingSubstitute the value of m (which is -6) into the formula for point-slope form.
[tex]y-y_1=-6(x-x_1)[/tex]
Now, substitute 6 and 4 as [tex]x_1[/tex] and [tex]y_1[/tex] respectively.
[tex]y-4=-6(x-6)[/tex]

-6m-12=5-2m−6m−12=5−2m
2 Add 6m6m to both sides.
-12=5-2m+6m−12=5−2m+6m
3 Simplify 5-2m+6m5−2m+6m to 5+4m5+4m.
-12=5+4m−12=5+4m
4 Subtract 55 from both sides.
-12-5=4m−12−5=4m

The Los Angeles area experiences many earthquakes. In 1994, the Northridge earthquake measured 6.7 on the Richter scale. In 2014, Los Angeles experienced an earthquake that measured 5.1 on the Richter scale. Compare the intensities of the two earthquakes. Use a logarithmic model to solve. Round to the nearest whole number.
Answers
Answer:
[tex]I_1=40I_2[/tex]
Step-by-step explanation:
[tex]M_1[/tex] = Magnitude of 1994 earthquake = 6.7
[tex]M_2[/tex] = Magnitude of 2014 earthquake = 5.1
[tex]I_1[/tex] = Intensity of 1994 earthquake
[tex]I_2[/tex] = Intensity of 2014 earthquake
[tex]I_0[/tex] = Zero-level earthquake the same distance from the epicenter = 0.001 mm
Magnitude is given by
[tex]M_1=\log(\dfrac{I_1}{I_0})\\\Rightarrow I_010^{M_1}=I_1\\\Rightarrow I_1=I_010^{6.7}[/tex]
[tex]M_2=\log(\dfrac{I_2}{I_0})\\\Rightarrow I_010^{M_2}=I_2\\\Rightarrow I_2=I_010^{5.1}[/tex]
Dividing the above intensities with each other we get
[tex]\dfrac{I_1}{I_2}=\dfrac{I_010^{6.7}}{I_010^{5.1}}\\\Rightarrow \dfrac{I_1}{I_2}=39.81\approx 40\\\Rightarrow I_1=40I_2[/tex]
The intensity of the earthquake in 1994 was 40 times stronger than the earthquake in 2014.

Explanation:
A factor is a number that divides into another number exactly and without leaving a remainder. For instance, factors of 15 are 3 and 5, because 3×5 = 15. Some numbers have more than one factorization (more than one way of being factored). For example, 12 can be factored as 1×12, 2×6, or 3×4.

If a function is defined by the formula y=1/2x + 3 and its domain is given by the set {-4,0,8}, then which of the following sets gives the function's range?
Answers
Answer:
y = {1, 3, 7}
Step-by-step explanation:
Given
y = ½x + 3
Domain: {-4, 0, 8}
Required
Determine the range of the function
To do this, we simply substitute each value of the domain in the given expression
We start with the first
Substitute -4 for x in y = ½x + 3
y = ½ * -4 + 3
y = -2 + 3
y = 1
Then 0
Substitute 0 for x in y = ½x + 3
y = ½ * 0 + 3
y = 0 + 3
y = 3
Lastly, 8
Substitute 8 for x in y = ½x + 3
y = ½ * 8 + 3
y = 4 + 3
y = 7
Hence, the range of the function is:
y = {1, 3, 7}

What is the slope of a line that passes through the points (0, 1) and (2, 6)?
please answer fast as can
Answers
Answer:
[tex]\boxed {\boxed {\sf m=\frac{5}{2}}}[/tex]
Step-by-step explanation:
The slope formula is the change in y over the change in x, or:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x₁,y₁) and (x₂, y₂) are the points the line passes through.
The points given are (0,1) and (2,6). Therefore:
[tex]x_1=0\\y_1=1\\x_2=2\\y_2=6[/tex]
Substitute the values into the formula.
[tex]m=\frac{6-1}{2-0}[/tex]
Solve the numerator.
[tex]m=\frac{5}{2-0}[/tex]
Solve the denominator.
[tex]m=\frac{5}{2}[/tex]
This fraction can not be simplified further, so it is our answer.
The slope of the line is 5/2
Answer:
m=5/2
Step-by-step explanation:
We know that,
[tex]Slope\ (m)=\frac{Rise}{Run}\\Slope\ (m)=\frac{y_2-y_1}{x_2-x_1} \\As here,\\x_1=0, x_2=2\\y_1=1, y_2=6\\Hence,\\Slope(m)\ of\ the\ following\ line\ =\frac{6-1}{2} =2.5[/tex]

A train travels at 45 mph for 3 h and then increases its speed to 55 mph for 2 more hours. How far does the train travel in the 5-hour period
Answers
Answer:
245milesStep-by-step explanation:
Step one:
given that the first 3 hours the train travels at a speed of 45 mph.
i.e Time = 3 hours
speed =45 mph
distance=?
we know that speed = distance/time
distance= speed*time
distance= 45*3
distance=135miles
Step two:
For the nex two hours it travels at 55 mph
i.e time= 2hours
speed= 55mph
distance=?
distance= speed*time
distance= 2*55
distance= 110mile
Step three:
Hence for a total of 5 hours drive, the total distance covered is
135+110= 245miles

Answers
Answer:
1/5
Step-by-step explanation:
[tex]\frac{2-1}{3--2} = \frac{1}{5}[/tex]
Answer: 1/5
Step-by-step explanation: Following our hint,
let's start with the slope formula.
m = y₂ - y₁ / x₂ - x₁
We take the second y minus the first y over the second x minus the first x.
So we have m = 2 - 1 / 3 - (-2) or 1 / 5.
So our slope is 1/5.
if a scale drawing of a car is 3 inches and the real car is 15 feet what is the scale and scale factor
Answers
Step-by-step explanation:
Given parameters:
Scale drawing of the car = 3 inches
Real car = 15feet
Unknown:
Scale = ?
Scale factor = ?
Solution:
The scale is the ratio of the model dimension to the real-life representation.
In this problem, express both quantities in the same unit;
1 foot = 12 inches
15 feet = 15 x 12 = 180inches
Scale;
drawing of the car : Real car
3 inches : 180 inches
Scale 1 inches on drawing is 60inches in real life
Scale factor;
[tex]\frac{real life dimension}{drawing dimension}[/tex] = [tex]\frac{60 inches }{1inches }[/tex] = 60
