5(x + 2) = 2(x – 4)
-4(x + 3) = 4(x - 1)
ANSWERS (A,E)

Answers

Answer 1

The equation that have no solution is:  6x + 1 = 3(2x - 4).

The correct option is the first option.

Here, we have to check which of the equations have no solution, we need to solve each equation and see if they lead to a contradiction or an inconsistency.

If the variable (x) cancels out during the solving process, it means that the equation has no solution.

1) 6x + 1 = 3(2x - 4)

Expand the right side: 6x + 1 = 6x - 12

Subtract 6x from both sides: 1 = -12

In this case, we end up with a contradiction (1 = -12), which means there is no solution.

2) 2 - 5x = 7x - 12

Add 5x to both sides: 2 = 12x - 12

Add 12 to both sides: 14 = 12x

Divide by 12: x = 14/12 = 7/6

This equation has a solution.

3) 4(3 - x) = 2(6 - 2x)

Expand both sides: 12 - 4x = 12 - 4x

Subtract 12 from both sides: -4x = -4x

In this case, the variable (x) cancels out, which means any value of x would satisfy the equation.

So, this equation has infinitely many solutions.

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

Expand both sides: 5x + 10 = 2x - 8

Subtract 2x from both sides: 3x + 10 = -8

Subtract 10 from both sides: 3x = -18

Divide by 3: x = -18/3 = -6

This equation has a solution.

5) -4(x + 3) = 4(x - 1)

Expand both sides: -4x - 12 = 4x - 4

Add 4x to both sides: -4x - 4x - 12 = 4

Combine like terms: -12 - 4 = 8x

Combine like terms on the left side: -16 = 8x

Divide both sides by 8 to isolate x: x = -2

This equation has a solution.

So, the equation that have no solution is:  6x + 1 = 3(2x - 4).

Hence, The correct option is the first option.

Answer 2

Final answer:

To determine which equations have no solution, we need to solve each equation and see if any values of x make the equation false. The equations that have no solution are 6x + 1 = 3(2x – 4) and 4(3 – x) = 2(6 - 2x).

Explanation:

To determine which equations have no solution, we need to solve each equation and see if any values of x make the equation false. Let's go through each equation:

6x + 1 = 3(2x – 4)
Simplifying both sides, we get 6x + 1 = 6x - 12. Subtracting 6x from both sides gives us 1 = -12, which is not true. Therefore, this equation has no solution.2 - 5x = 7x – 12
Combining like terms, we get -5x - 7x = -12 - 2, which simplifies to -12x = -14. Dividing both sides by -12, we find that x = 7/6. Therefore, this equation has a solution.4(3 – x) = 2(6 - 2x)
Simplifying both sides, we get 12 - 4x = 12 - 4x. This equation is true for all values of x. Therefore, this equation has infinitely many solutions.5(x + 2) = 2(x – 4)
Expanding both sides, we get 5x + 10 = 2x - 8. Combining like terms, we get 3x = -18. Dividing both sides by 3, we find that x = -6. Therefore, this equation has a solution.-4(x + 3) = 4(x - 1)
Expanding both sides, we get -4x - 12 = 4x - 4. Adding 4x to both sides gives us -4 = 8x - 4. Adding 4 to both sides gives us -8 = 8x. Dividing both sides by 8, we find that x = -1. Therefore, this equation has a solution.

So, the equations that have no solution are 6x + 1 = 3(2x – 4) and 4(3 – x) = 2(6 - 2x). The correct answers are A and E.

If the mixing container only holds 40 ounces of paint, then what is the most green paint the artist can make, and what recipe should she use?​

Answers

Answer:

she can make 40 ounces of green paint

Step-by-step explanation:

20 ounces of yellow paint and 20 ounces of blue paint

The most green paint she can make would be 28 ounce of yellow + 8 ounce of blue which would give us 36 ounce of green paint. Since the container can only hold 40 ounce.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

An artist mixes yellow and blue paint to make the perfect shade of green. She uses 2 ounces of blue paint for every 7 ounces of yellow paint

We need to find the most green paint the artist can make if the mixing container only holds 40 ounces.

Amount of blue paint = 2 ounce

Amount of yellow paint = 7 ounce.

Paint the mixing container can hold = 40 ounce.

Most green paints she can make. This is a ratio question

Yellow green

7 = 2

14 =4

21 =6

28 = 8

35 = 10

Hence, The most green paint she can make would be 28 ounce of yellow + 8 ounce of blue which would give us 36 ounce of green paint. Since the container can only hold 40 ounce.

Analyzing each statement, we have

a. On a coordinate plane, an absolute value function opens down.

The absolute value function f(x)=∣x∣ does not have an inverse that is a function because it fails the horizontal line test.

Specifically, any horizontal line intersects the graph of the absolute value function at most twice.

So, its inverse is not a function.

b. On a coordinate plane, an exponential function increases from quadrant 2 into quadrant 1.

Exponential functions, such as

f(x) = eˣ or f(x) = abˣ, do have inverses that are functions.

They pass the horizontal line test, and their inverses are logarithmic functions.

c. On a coordinate plane, a cubic function has an x-intercept of (0, 0).

A cubic function, such as f(x) = x³, does have an inverse that is a function.

The cubic function has an x-intercept at (0, 0), and its inverse is a cubic root function.

A trapezoid has an area of 30m^2. if all of its side lengths are tripled, what will its new area be​

Answers

Answer:

270

Step-by-step explanation:

Because we do not know what the side lengths are, as long as they multiply to 30m^2, it's fine

For this question, let's just say the base is 5, and the height is 6. If we triple 5, we get 15, and if we triple 6, we get 18. 15*18=270

Now what if, the sides are not 5 and 6. Will the area still be the same? Let's find out.

10*3=30 so we can say for this answer, the base is 3, and the height is 10.

10 tripled is 30, and 3 tripled is 9. 30*9=270

So as we look at these 2 answers. we can conclude that the new area, no matter the side lengths, will be 270

Final answer:

Benito drew a line with a slope of 3. This is determined by using the slope formula and identifying the rate of change in the y coordinates with respect to the x coordinates for each line drawn by the different students.

Explanation:

To find the slope of a line on a coordinate plane, we can use the slope formula: slope = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are points on the line.

Analise's line goes through points (-3,0) and (0,1). The slope would be (1-0)/(0-(-3)) = 1/3.Benito's line goes through points (0, -1) and (1, 2). The slope is (2-(-1))/(1-0) = 3.Charlie's line is vertical, going through the points (0,-3) and (0,3). Vertical lines do not have a defined slope.Dariya's line passes through (2,3) and (3,0). The slope is (0-3)/(3-2) = -3.

Therefore, the student who drew a line with a slope of 3 is Benito.

Square ABCD has a side length of 4 inches. The square is dilated by a scale factor of 4 to
form square A'B'C'D'. What is the side length of square A'B'C'D' ?

Answers

Answer:

The side of square A'B'C'D' is 16 inches

Step-by-step explanation:

Given

Length of Square ABCD = 4 inches

Dilated with a scale factor of 4

Required

Length of square A'B'C'D'

To dilate something means to enlarge or reduce the size of that thing, depending on the scale factor.

Consider the following conditions

When the scale factor is greater than 1, then the size of new shape will be bigger than the dilated shapeWhen the scale factor is equal to 1, the new shape will maintain the same size as the dilated shapeWhen the scale factor is less than 1 but greater than 0, the size of new shape will be smaller than that of the dilated shape.

Having mentioned the conditions of dilation, Here, the "thing being dilated" is a square (ABCD) on a scale factor of 4.

The scale factor is greater than 1; so, the new shape (A'B'C'D) will be bigger than the previous shape (ABCD)

Now, how is the new size calculated?

The new size is calculated by multiplying the length of the previous shape by its scale factor;

In other words,

New Length = Old Length * Scale Factor

Where

Old Length = Length of ABCD = 4 inches

Scale Factor = 4

By Substitution,

New Length = 4 inches * 4

New Length = 16 inches

Hence, the side of square A'B'C'D' is 16 inches
