y=x+5

Step-by-step explanation:

Looking at the answer choices, at first glance you see x=0 and y=5, this mean the y-intercept is 5. And in the equation y=mx+b, positive 5 will go into b.

The only answer with +5 as y-intercept is y=x+5

Now what if there are multiple +5 for y-intercept?

If there is multiple +5, you will also need to find the slope, you can find the slope by using

In order to find the equation, they're is 2 ways of doing. Plugging in or using Y-Y1=M(X-X1). For plugging in, replace the x with 1 x value and plug in y for the corresponding x value. Or you can plug in all the x and y values into the equation shown and put the number on the left to the right and you'll get your equation immediately. Good luck on the Quizziz!

Answer:

p ≈ 19.19 %

Step-by-step explanation:

198 - p×198/100 = 160

19800 - 198p = 16000

19800 - 16000 = 198p

3800 = 198p

p = 19.19 %

The percentage change is -19.19%.

The percentage change (or) the percentage change of a quantity is the ratio of the difference in the quantity to its initial value multiplied by 100.

Given that,  a price of £198 is decreased to £160.

Percentage change = (final - initial) amounts ÷ initial amount × 100

Percentage change = (160 - 198) / 198 × 100

= - 38 / 198 × 100

= - 19.19%

The negative is showing decrease.

Hence, the percentage change is - 19.19%

Step-by-step explanation:

Answer:

Pete, Lisa, Tony, Max

Step-by-step explanation:

Lisa is 4 ahead Tony, putting Tony 4 behind Lisa

Pete is 8 ahead Max, putting Max 8 behind Pete

Lisa is also 6 ahead Max, putting Max 6 behind Lisa

So, Pete is 8 ahead Max, but lisa is 6 ahead Max, so Pete is ahead of Lisa by 2

Then lisa is 4 ahead Tony, so tony is 4 behind lisa and 6 behind Pete

Therefore (I know its confusing) The order is Pete, Lisa, Tony, Max

Final answer:

By analyzing the time differences between their finishes, we can determine that the friends cross the finish line in this order: Lisa first, Pete second, Tony third, and Max last.

Explanation:

To solve the question regarding the order in which four friends cross the finish line, we will use logical reasoning and simple arithmetic based on the information provided. Lisa finishes four hours ahead of Tony, Pete is eight hours ahead of Max, and Max finishes six hours after Lisa. From the given information, we can set up a sequence of events to determine the order in which they finish.

We divide the number line into intervals to understand how far we need to move left or right when solving equations. This division into intervals creates a physical representation that helps visualize calculations and absolute differences between numbers.

We divide the number line into intervals so we know how far to move left or right when doing equations. For understanding, let's consider an example. If we're working with whole numbers and the number line is divided into single-unit intervals, moving to the right from 0 to 5 means we've added 5 to our original number. Similarly, moving to the left of 0 to -5 means we've subtracted 5 from our original number.

The division of the number line helps to visualize the calculation process and see physical representation of absolute differences between numbers. For example, if we make the distance between each interval equal to one unit, the distance between 1 and 3 on the number line is 2 units, which corresponds to the absolute difference between these numbers.

Answer:

|x - 1| = 6

Step-by-step explanation:

After step 2, we have that:

(x - 1)^2 = 36

and after step 4, we have the results:

x = -5 or x = 7

After step 2, what we can do in step 3 is: use square root in both sides of the equation:

|x - 1| = 6

This equation can be split in two:

x - 1 = 6 -> x = 7

x - 1 = -6 -> x = -5

So Seth could write this equation in step 3:

|x - 1| = 6

The value of x from the given expression are 5 and 7

Given the expression

5(x - 1)^2 = 18

Step 2 as shown is given as:

(x - 1)^2 = 36

Take the square root of both sides

√(x - 1)^2 = √36

x - 1 = 6

The solutions are x - 1 = 6 and x + 1  = 6

x = 6 + 1 = 7

x = 6 - 1

x = 5

Hence the value of x from the given expression are 5 and 7

Answer:

$8.75

Step-by-step explanation:

To calculate this you could use two methods. The first method is to find out what 10% is and multiply it by 5. The second method is to calculate 50% using the formula.

Method 1:

To work this out you would simply divide 17.50 by 10, which is 1.75. This is because percentages are out of 100 and so by dividing by 10 we are finding out what 10% is. Then you would multiply 1.75 by 5, which is 8.75. Then you would minus 8.75 from 17.50, which is 8.75.

1) Divide 17.50 by 10.

[tex]17.50/10=1.75[/tex]

2) Multiply 1.75 by 5.

[tex]1.75*5=8.75[/tex]

3) Minus 8.75 from 17.50.

[tex]17.50-8.75=8.75[/tex]

4) The new price is $8.75

Method 2:

The formula for percentages is.

[tex]\frac{percentage}{100} * amount[/tex]

To work this out you would first divide 50 by 100, which gives you 0.5. Then you would multiply 0.5 by 17.50, which is 8.75. Then you would minus 8.75 from 17.50, which is 8.75.

1) Divide 50 by 100.

[tex]50/100=0.5[/tex]

2) Multiply 0.5 by 17.50.

[tex]17.50*0.5=8.75[/tex]

3) Minus 8.75 from 17.50.

[tex]17.50-8.75=8.75[/tex]

4) The new price is $8.75.

The probability of selecting a yellow disk from a bag of colored disks is 1/5 or 20%

The probability of selecting a yellow disk is 5 out of 25 disks, which simplifies to 1/5 or 0.2 (20%).

If you reach into the bag without looking, you have a 20% likelihood of randomly selecting a yellow disk from the total number of disks.

a. The probability that a yellow disk will be selected is 5/25 or 1/5, b. Complete the sentence to describe the likelihood of randomly selecting a yellow disk: It is 1/5 that a yellow disk will be randomly selected from the bag.

The probability of selecting a yellow disk from the bag is 1/5, as there are 5 yellow disks out of a total of 25 disks. This means that for every 5 disks chosen randomly, one is expected to be yellow. The likelihood of randomly selecting a yellow disk is thus 1 out of 5, or 20%. This probability reflects the relative abundance of yellow disks in the bag compared to other colors. With each random selection, there's an equal chance of picking any individual disk, making understanding probabilities crucial for predicting outcomes in random selections.

The parallelogram diagonal theorem pertains to vector addition and subtraction, where the diagonals of a parallelogram indicate the resultant and the difference of two vectors. The precision of the resultant vectors is attained through trigonometry laws or by drawing the vectors to scale, with the alternative method of components simplifying calculations. The Pythagorean theorem also aids in accurately determining the lengths of resultants in right-angled vector scenarios.

In geometry, the parallelogram diagonal theorem states that when two vectors form the sides of a parallelogram, the diagonals of that parallelogram represent the sum and the difference of the two vectors. This can be understood by two distinct operations:

The magnitude and direction of these resultant vectors cannot simply be calculated as the arithmetic sum or difference of the magnitudes of individual vectors A and B. Instead, we must apply trigonometry laws or construct the vectors to scale and measure directly if precision is not paramount. The method of components, involving breaking down vectors into their orthogonal components along the axes, offers an alternative by circumventing complex algebraic calculations.

To add multiple vectors, we can sequentially apply the parallelogram rule to combine pairs until we derive the overall resultant. The process is both commutative and associative, meaning that the order of addition does not affect the final resultant vector.

The Pythagorean theorem, crucial for right triangles, allows us to calculate the straight-line distance (hypotenuse) when we know the lengths of the other two sides. It serves as another example of how vector components can simplify the calculation of resultants in orthogonal directions.

Answer:

Step-by-step explanation:

Given that the two equations -3x + 6 = 21  and -3x + 6 <21

From the given equations -3x + 6 = 21  and -3x + 6 <21 we have that

-3x+6-6=21-6

-3x=15

[tex]x=-\frac{15}{3}[/tex]

-3x + 6 <21

-3x+6-6<21-6

-3x<15

[tex]x< -\frac{15}{3}[/tex]

The first equation is a statement of equality, while the second is an inequality. The process is solving equations and inequalities.

The process used to solve the equations involves identifying whether the given expressions are equations or inequalities and then applying appropriate techniques to find the solution.

For the equation [tex]\( -3x + 6 = 21 \)[/tex], the goal is to find the value of [tex]\( x \)[/tex] that makes the equation true. We start by isolating [tex]\( x \)[/tex] on one side of the equation. By subtracting 6 from both sides and then dividing by -3, we find [tex]\( x = -5 \)[/tex]. This is the solution to the equation.

On the other hand, for the inequality [tex]\( -3x + 6 < 21 \)[/tex], the goal is to find the values of [tex]\( x \)[/tex] that satisfy the inequality. We follow similar steps as with the equation but with one crucial difference: when dividing by a negative number, the direction of the inequality sign must be reversed. After isolating [tex]\( x \)[/tex], we find [tex]\( x > -5 \)[/tex]. This represents all values of [tex]\( x \)[/tex] that make the inequality true.

In summary, the process involves understanding whether we are dealing with equations or inequalities, isolating the variable, and solving for its value. For inequalities, attention must be paid to reversing the inequality sign when dividing by a negative number.

Answer:

3/4

Step-by-step explanation:

You want the smaller answer. 3/4

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. Out of the two given options, 3/4 is closer to 1.

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.

The value of 13/10 is equal to 1.3, while the value of 3/4 is 0.75. Therefore, the difference between the two numbers from 1 will be equal to,

[tex]D_1 = 1.3-1 = 0.3[/tex]

[tex]D_2 = 1-0.75 = 0.25[/tex]

Since the value of 0.3 is greater than 0.25, therefore, the gap between 13/10 and 1 will be more than 3/4 and 1.

Hence, out of the two given options, 3/4 is closer to 1.
