The correct options are B and C, or 3x-21 and -3x21, since the inequality sign must be "flipped," or reversed, whenever you multiply or divide both sides of the inequality.

In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.

In the triangle WYC, the length of the side YC is 4.76 units.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know a line segment parallel to a side of a triangle divides the other two sides in the same ratio.

Given, In a ΔMRC and ΔWYC MR = 14, CR=28, WY = 6, and MW = 17.88.

Now, MR = 14 and MW = 17.88.

Therefore, (MW/MR) = 17.88/14 = 1.28.

So, If WY = 6, then WE = (1.28)(6) = 7.66.

Now, In the ΔWYC, WY = 6 and WE = 7.66.

Therefore from the Pythagoras's theorem,

WE² - WY² = YC².

YC² = (7.66)² - 6².

YC² = 22.68.

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.

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

Determine which integer in the solution set will make the equation true. t − 42 = −14 {−56, −28, 3, 28}

replace 28 for t:

t − 42 = −14

28 − 42 = −14

−14 = −14

Answer:

  28

Step-by-step explanation:

You want the value of t that satisfies t − 42 = −14.

The solution to this 1-step linear equation is to add the opposite of the unwanted constant (-42).

Adding 42 to both sides of the equation gives ...

  t -42 +42 = -14 +42

  t = 28

The integer that makes the equation true is 28.
