Help Me Answer Question 2

Answers

Answer 1

Answer:

x + x + x

Step-by-step explanation:

We have 3y and are asked to express it equivalently with the answers provided.

I will go over the flaws of each answer and single it down to the correct one.

x * x * x would equal x^3, since this is being multiplied.

x^3 is equal to x * x * x, therefore it is not correct.

x + 3 is not correct because you cannot add numbers or variables that are not like terms, so it would not equal to 3y.

x + x + x would equal to 3y because they are all like terms and do not form exponents.

Answer:

75 points ( more than?? you didn't add the drop-down list ) today's score.

Hope this helps!

Step-by-step explanation:

y = mx + b

y = 5x + b

(50) = 5(6) + b  -> b = 20

y = 5x + 20

If Carlos plays the game today for 0 min, he will get a score of 20 ( odd...  how is that possible )

But tomorrow, he plans to play for an extra 15 min, so he will get a score of 95 ( ( 5 × 15 ) + 20 ). The question asks for how much his score will change so his score will change by 75 points ( 95 - 20 ).

You could also just do 15 × 5 to get 75 :)

Solve the following system of equations using the elimination method
y + 2x = 1
3x - 2y = 5

Answers

   The solution to the system of equations is x = 1,y = -1 by using the elimination method.

  To solve the system of equations using the elimination method, we'll eliminate one variable by adding or subtracting the equations. Here's how:

  Multiply the first equation by 2 to make the coefficients of y in both equations opposite each other:

Equation 1: 2(y + 2x) = 2(1) => 2y + 4x = 2

  Rewrite the second equation as:

Equation 2: 3x - 2y = 5

  Now, we can add the modified Equation 1 to Equation 2 to eliminate y:

(2y + 4x) + (3x - 2y) = 2 + 5

  Simplifying, we get:

4x + 3x = 7

7x = 7

  Divide both sides of the equation by 7 to solve for x:

x = 7/7

x = 1

  Substitute the value of x into either of the original equations. Let's use the first equation:

y + 2(1) = 1

y + 2 = 1

  Subtract two from both sides of the equation to solve for y:

y = 1 - 2

y = -1

  Therefore, the solution to the system of equations is:

x = 1

y = -1

jureks brother is 6 years older than him .Together they are 22 years old ,how old are the brothers.Write down the correct equation?

Answers

Answer:

Jurek is 8. His brother is 14

Step-by-step explanation:

let's call Jurek J, and let's call his brother B.

his brother is 6 years older than Jurek.

So, B = J + 6.

B + J = 22

(J + 6) + J = 22

2J + 6 = 22

2J = 16

J = 8

so Jurek is 8

B + J = 22, B = 22 - J = 22 - 8 = 14.

Brother is 14

Write the following number in expanded form: fifty-four and eight tenths

Answers

Fifty-four and eight tenths" can be expressed in expanded form as the sum of 54 (representing 50 + 4) and 0.8, which represents the decimal part.

To write the number "fifty-four and eight tenths" in expanded form, we can break it down into its individual place values and numerical components.

The number "fifty-four" can be broken down as follows:

The digit 5 represents the value of 50, which is 5 tens.

The digit 4 represents the value of 4, which is 4 ones.

So, "fifty-four" can be expressed as 50 + 4.

Next, we have "eight tenths". This can be expressed as 8/10 or simply 0.8 since each tenth is equal to 0.1.

Putting it all together, the number "fifty-four and eight tenths" can be written in expanded form as:

50 + 4 + 0.8

Simplifying further, we can combine the integer and decimal parts:

54 + 0.8

Therefore, the expanded form of "fifty-four and eight tenths" is 54 + 0.8.

If f(1) = 0, what are all the roots of the function f (x) = x cubed + 3 x squared minus x minus 3? Use the Remainder Theorem.

Answers

The roots of the cubic function:

f(x)=  x³ + 3x² - x - 3

are x = 1, x= -1, x = -3

How to find the roots of the function?

We want to find the roots of the function:

f(x)=  x³ + 3x² - x - 3

We know that x = 1 is a root, because f(1) = 0.

Then we can write that function as:

(x - 1)*(x - a)*(x - b)

Where a and b are the other two roots, then we need to solve:

x³ + 3x² - x - 3 = (x - 1)*(x - a)*(x - b)

Expanding the right side, we will get:

x³ + 3x² - x - 3 = x³ + (-a - b - 1)x² + (a + b + ab)x + (-ab)

Comparing like terms, we can see that:

(-a - b - 1) = 3

(a + b + ab) = -1

(-ab) = -3

The third equation gives:

ab = 3

Replacing that in the second one we get:

a + b + 3 = -1

a + b = - 1 - 3 = -4

a + b = -4

a = -4 - b

Replacing that in the relation above:

ab = 3

(-4 - b)*b = 3

-4b - b² = 3

b² + 4b + 3  = 0

The zeros of that function are:

[tex]b = \frac{-4 \pm \sqrt{4^2 -4*3*1} }{2*1} \\\\b = \frac{-4 \pm 2}{2}[/tex]

Then if b is the value when we take the positive sign:

b = (-4 + 2)/2 = -1

the value of a is:

a = -4 - b = -4 + 1 = -3

These are the other two roots.

kylie is wrapping a book for her sister.The box is 20" x 12"x 2 1/2. the book she wants to put it in is 18" x 3 1/2 x 8.How much empty space will be in the box once kyile puts the book inside

Answers

Answer:

96 cubic inches

Step-by-step explanation:

To calculate the empty space that will be left in the box once the book is inside, we need to find the difference between the volume of the box and the volume of the book.

Volume of the box:

20" x 12" x 2 1/2" = 600 cubic inches

Volume of the book:

18" x 3 1/2" x 8" = 504 cubic inches

Empty space in the box:

600 cubic inches - 504 cubic inches = 96 cubic inches

Therefore, there will be 96 cubic inches of empty space left in the box once Kylie puts the book inside.

A rectangular prism with a square base has a height of 17.2 cm and a volume of 24.768 cm² What is the side length of its base?

Answers

If rectangular prism with a square base has a height of 17.2 cm and a volume of 24.768 cm², the side length of the square base is 1.2 cm.

Let's denote the side length of the square base as x cm. Then, the volume of the rectangular prism can be expressed as V = x² * 17.2 cm³, and its surface area can be expressed as S = 2x² + 4x * 17.2 cm².

We are given that the volume of the rectangular prism is 24.768 cm³, so we can write the equation:

x² * 17.2 cm³ = 24.768 cm³

Simplifying this equation, we get:

x² = 24.768 cm³ / 17.2 cm² = 1.44 cm²

f(x)= x², -2≤ x ≤ 1.
-2x, x > 1

Answers

Answer:

Step-by-step explanation:

To graph the function, we'll break it down into three parts based on the given conditions.

For x ≤ -2:

The function f(x) = x + 6 is valid in this range. We'll plot a straight line with a slope of 1 and a y-intercept of 6. Since x ≤ -2, we'll extend the line towards the left indefinitely.

For -2 ≤ x ≤ 1:

The function f(x) = x² is valid in this range. We'll plot a curve representing a quadratic function. The graph starts at the point (-2, 4), curves upward, and ends at the point (1, 1).

For x > 1:

The function f(x) = -2x is valid in this range. We'll plot a straight line with a negative slope of -2. Since x > 1, we'll extend the line towards the right indefinitely.

Combining these three parts, we get the graph of the function as follows:

Answers

The area of the larger square is 900% of the area of the smaller square.

Let's assume that the side of the smaller square is "s". Therefore, the area of the smaller square will be:

Area of smaller square = s²

Now, the sides of the square are increased by a scale factor of 3, which means that the new side length of the larger square will be 3s. The area of the larger square will be:

Area of larger square = (3s)² = 9s²

To find the percentage of the larger square with respect to the smaller square, we need to divide the area of the larger square by the area of the smaller square, and then multiply by 100:

(9s²/s²) x 100 = 900%

This means that the larger square is 9 times the area of the smaller square.
