Answer:
[tex]P' = (1,-2)[/tex]
Step-by-step explanation:
Given
[tex]P = (1.6)[/tex]
[tex]Q = (-6,1)[/tex]
Reflection over: [tex]y = 2[/tex]
Required
Determine the coordinates of P'
From the given coordinates, the y coordinates of P is 6 and the line of reflection is at y = 2
Since we are to reflect over y = 2, only the y coordinate of P will be affected.
The idea behind reflecting a point over a line is to have an equal distance between [the original point & the line of reflection] and [the new point & the line of reflection]
So, what to do is:
First, calculate the difference between the y coordinates of P and the line of reflection.
The y coordinate of P is 6 and the line of reflection is at y = 2.
So, the difference is: 6 -2 = 4
Next, subtract the calculated difference from the line of reflection to get the y coordinate of P'
y coordinate of P' = 2 - 4 = -2
Hence, the coordinate of P' is: (1,-2)

the linear function g is defined by g(x)=4x. show that g(3) and g(2) have a difference of 4.
Answer:
the answer is D.
Step-by-step explanation:
well, the y-intercept for f(x) is at
as you can see from the slope-intercept form is at 4, and it has an slope of 2/3.
for g(x), well an y-intercept is when x = 0, what is it from that table? well, is at 0,3, so when x = 0, y = 3, so no dice on that one.
c)
whenever an x-intercept occurs, y = 0, for f(x) that's at
what about the x-intercept for g(x)? well, let's check, when is y = 0? aha! at -9, 0, so when y = 0, x = -9, so no dice on that one either.
d)
well, what is the slope of g(x) anyway? well, let's pick two points off the table to get it hmmm the first two let's use,
and from a), using the slope-intercept form, we know f(x) has a slope of 2/3.
well, 2/3 is larger than 1/3, so no dice.
b)
well, you already know.

An experiment compares the height of two plants over time. A plant was 2cm tall at the beginning of the experiment and grew 0.5 centimeters each day. The functions f(t)=0.5+2 represents the height of the plant in centimeters after t days . Which plant for f, or g was growing faster ?
Answer:
Plant F;
Plant G;
Plant G
Step-by-step explanation:
Given that:
Plant F :
f(t)=0.5x+2
From the growth graph given for the second plant ; plant G
Point 1 (0, 5) ; point 2(16, 9)
Slope = Rise / Run = (9 - 5) / (16 - 0) = 4 / 16 = 0.25
Intercept = 5 ( point where fitted line crosses the y-axis)
Linear slope intercept relation : y = mx + c
m = slope ; c = intercept
g(x) = 0.25x + 5
The slope value of plant F = 0.5
Slope value of plant G = 0.25
F > G
Hence, F is growing at a faster rate
The starting height is given by the intercept value of the two equations ;
Plant F, intercept = 2
Plant G, intercept = 5
G > F
Hence, G was taller, to begin with
Height after 8 days :
x = 8
f(8)=0.5(8)+2
f(8) = 4 +2 = 6
g(8) = 0.25(8) + 5
g(8) = 2 + 5 = 7
Hence, G was taller after 8 days
The value of Tonya's car is $21,000. The car's value depreciates at a rate of 15% per year.
Which function represents the value of the car after t years?
O f(t) = 1.15(21,000)
O f(t) = 21,000(1.15)
O f(t)21,000(0.85)
O f(t) = 0.85(21,000)
Answer:
f(t) = 0.85(21,000)
Step-by-step explanation:
100% - 15% = 85% 0r in decimal form 0.85
0.85 x the original pricen 21,000
Answer:
the answer for this question is: f(t)=21,000(0.85)^t
Step-by-step explanation:
well since its asking what function represents the value, you have to convert the 15 percent into a decimal. so when you put the equation together you can see its 0.85.
hope it helps! :)
A car uses 1 liter of gas every 12 kilometers. How many meters can the car travel on 3 liters of gas? 36 meters 3,600 meters 360 meters 36,000 meters
Answer:
36,000 meters. 12km= 12,000m multiply by 3l of gas.
Step-by-step explanation:
The car will travel 36000 meters using 3 liters of gas as per linear equation.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, 'A' is a coefficient and 'B' is constant".
Given, a car uses 1 liter of gas every 12 kilometers.
Therefore, using 3 liters of gas, the car will go
= 3 × 36 kilometers
= 36 kilometers
= 36000 meters
With 3 liters of gas, the car will travel 36000 meters.

Solve:3x+3y=27 and its algebra
Answer: X=9-y
Step-by-step explanation:
Answer:
x = 9 - y
y = 9 - x
Step-by-step explanation:
Solving for X:[tex]3(x + y) = 27[/tex]
[tex]x + y = \frac{27}{3} [/tex]
[tex]x + y = 9[/tex]
[tex]x = 9 - y[/tex]
Solving for Y:[tex]3(x + y) = 27[/tex]
[tex]x + y = \frac{27}{3} [/tex]
[tex]x + y = 9[/tex]
[tex]y= 9 - x[/tex]
Hence, the answer for x is x = 9 - y and the answer for y is y = 9 - x.

Answer:
m<a=56
m<b=34
m<c=56
Step-by-step explanation:
The rectangle is cut into two triangles. The total of a triangles angles is 180 degrees. The triangles are right triangles which means that the right angle is 90 degrees.
You already have an angle that measures 34 degrees.
Alternate interior angles are congruent. So, the given angle is equal to m<b.
Now add 90+34=124
To get the alternate interior angles (m<a and m<c) subtract 124 from 180 which equals 56 degrees.
