[tex]\frac{1}{4} = \frac{1}{4}.100 = 25[/tex]
Length of a meter cut into equal pieces = 1/2
[tex]\frac{1}{2} =\frac{1}{2}.100= 50[/tex]

Answer:
The lie is #3
Step-by-step explanation:
The only way to solve this is by testing each equation to see if it's true. Remember that dividing powers with the same base, in this case b, means you're just subtracting the exponents.
Substituting 5 for y in #1 gives us the equation [tex]\frac{b^9}{b^5}=b^4[/tex]. This is the same as saying [tex]b^9^-^5=b^4[/tex], which is true.
Substituting 7 for z and 2 for x in #2 gives us [tex]\frac{b^7}{b^2}=b^5[/tex]. Like we did for the first one, this is the same as [tex]b^7^-^2=b^5[/tex], which is also true.
That means that #3 is a lie, but substituting 2 for x anyway gives us [tex]\frac{b^8}{b^2}=b^8[/tex], or [tex]b^8^-^2=b^8[/tex]. This is not a true statement, and x would have to equal 0 for this to be true.

The equation of the transformed function is (c) g(x) = 4(1/3x)²
How to describe the transformation from the parent function?From the question, we have the following function that can be used in our computation:
f(x) = x²
g(x) = horizontally shrunk of f(x) by a factor 1/3 and vertical stretch by a factor of 4
The above equations implies that, we have the transformation to be:
Horizontally shrunk of f(x)Vertical stretch by a factor of 4Mathematically, this can be represented as
g(x) = 4f(1/3x)
Substitute the known values in the above equation, so, we have the following representation
g(x) = 4(1/3x)²
Hence, the transformed function si g(x) = 4(1/3x)²

A candle is 18 in. tall after burning for 3 hours. After 5 hours, it is 16.5 in. tall. Write a linear equation to model
the relationship between height h of the candle and time t. Predict how tall the candle will be after burning 8
hours.
a. h(t) = -0.75t + 20.25; 14.25 inches
b. h(t) = 0.75t + 15.75; 9.75 inches
c. h(t) = -0.75t + 15.75; 9.75 inches
d. h(t) = 0.75t + 20.25; 14.25 inches
Answer: To write a linear equation to model the relationship between the height h of the candle and time t, we need to find the slope and y-intercept of the line that represents this relationship.
The slope of the line is given by the rise over the run, or the change in the y-value (the height of the candle) over the change in the x-value (the time). We can calculate the slope by taking the difference in the height of the candle after 5 hours and 3 hours, and dividing it by the difference in the time:
slope = (16.5 - 18) / (5 - 3) = (-1.5) / (2) = -0.75
The y-intercept of the line is the point at which the line crosses the y-axis. This is the height of the candle when the time is 0. We can use the height of the candle after 3 hours as the y-intercept, since this is the height when the time is 3:
y-intercept = 18
We can use these values to write a linear equation in the form y = mx + b, where m is the slope and b is the y-intercept.
Plugging in the values we found, we get:
h(t) = -0.75t + 18
This is the linear equation that models the relationship between the height h of the candle and time t.
To predict how tall the candle will be after burning for 8 hours, we can plug in t = 8 into the equation:
h(8) = -0.75(8) + 18 = -6 + 18 = 12 inches
This means that the candle will be 12 inches tall after burning for 8 hours.
Therefore, the correct answer is (d) h(t) = 0.75t + 20.25; 14.25 inches.
To write a linear equation to model the relationship between the height of the candle and time, we can use the information given. We know that after 3 hours, the candle is 18 inches tall, and after 5 hours, it is 16.5 inches tall.
We can set up a system of linear equations to represent this information. Let's call the height of the candle h and the time t. Then we can set up the following system:
h = 18 - 3t
h = 16.5 - 5t
To solve this system, we can set the two equations equal to each other and solve for t:
18 - 3t = 16.5 - 5t
1.5 = 2t
t = 0.75
This tells us that the height of the candle decreases by 0.75 inches per hour.
Now we can use this information to predict how tall the candle will be after 8 hours. We can plug in 8 for t in the equation h = 18 - 3t to find the height of the candle:
h = 18 - 3(8)
h = 18 - 24
h = -6 inches
So the candle will be about 6 inches shorter after burning for 8 hours. This means it will be about 10.5 inches tall.
The correct option is c, h(t) = -0.75t + 15.75; 9.75 inches.
This is because we found that the height of the candle decreases by 0.75 inches per hour, which is represented by the coefficient of t in the equation. The y-intercept, 15.75, represents the initial height of the candle, which we found to be 16.5 inches.

Adam and Eric went hiking at different times. Adam is currently 73 feet above sea level while Eric is just starting at 24 feet below sea level. What is the difference in their elevations?
Answer: The answer is 97
Step-by-step explanation:
Since Adam is above sea level, the number 73 is positive. The number 24 would be negative since it's below sea level.
73 - ( -24) = 97
To check to make sure it's right we can do this:
-24 + 97 = 73

The point (2, 90) represents the value that after 2 weeks, Paul's math average is a 90. The
point (4, 50) represents the value that after 4 weeks, Paul's grade has dropped to a 50
because he doesn't do homework and doesn't know how to log into Quizlet. What equation
represents the line of Paul's grade downfall? (5 Points)
y = -0.10x + 130
y=20x-100
y = 20x- 130
y=0.10x+90
y=-20x+90
y=-20x+130
Answer:
The equation that represents the line of Paul's grade downfall is:
y = (-20)x + 130
This equation states that for every decrease of 1 in the value of x (representing the number of weeks), the value of y (representing Paul's math average) decreases by 20.
Step-by-step explanation:
To find the equation that represents the line of Paul's grade downfall, we can use the two given points to plot the line on a coordinate plane. The point (2, 90) represents the value that after 2 weeks, Paul's math average is 90, and the point (4, 50) represents the value that after 4 weeks, Paul's grade has dropped to 50. We can plot these two points on the coordinate plane as follows:
(2, 90)
(4, 50)
To find the equation of the line that passes through these two points, we can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope of the line and b is the y-intercept.
To find the slope of the line, we can use the formula:
m = (y2 - y1) / (x2 - x1)
Substituting the coordinates of the two points, we get:
m = (50 - 90) / (4 - 2)
= -40 / 2
= -20
To find the y-intercept of the line, we can substitute the coordinates of one of the points and the slope into the slope-intercept form of the equation:
y = mx + b
Substituting the coordinates of the point (2, 90) and the slope of -20, we get:
90 = (-20)(2) + b
= -40 + b
= b - 40
Solving for b, we get:
b = 90 + 40
= 130

-2x+9y=-9
-3x+5y=12
The co-ordinates will be(x,y) by the given equation the co-ordinates (9,1).
How to co-ordinate using subtraction method?
The technique of subtracting one vector's coordinates from another vector's coordinates is known as vector subtraction.Addition is represented by travelling up the -axis and to the right on the -axis. Subtraction is represented by going left and down the -axis. Since we are travelling below, we can deduct from our coordinate point, and since we are heading rightward, we can add to it.So, the given equations are
-2x+9y=-9 ⇒ (i)
-3x+5y=12 ⇒ (ii)
(i) * 5 ⇒ -10x + 45y = -45
(ii) * 9 ⇒ -27x + 45y = 108
⇒ 17x = 153
x = 9
Now, substitute x=9 in equation (i)
-2(9) + 9y = -9
-18 + 9y = -9
9y = -9 + 18
y = 9/9
y = 1
