Answer:

x = 2

Step-by-step explanation:

2(x - 1/2) = 3(5 - 2x) (distribute 2 and 3)

2x - 1 = 15 - 6x (add 6x on both sides)

8x - 1 = 15 (add 1 on both sides)

8x = 16 (divide both sides by 8)

x = 2

CHECK

2(2 - 1/2) = 3(5 - 2(2)) (solve what's in parenthesis)

2(1.5) = 3(1) (distribute)

3 = 3

False, every component of the matrix is multiplied by the same amount when you multiply a matrix by a number. A new matrix is created by this operation; it is known as a scalar multiple.

A rectangular matrix is a grouping of numbers in rows and columns. A matrix element/entry is the term used to describe each number in the matrix. The combination of a real number and a matrix is referred to as scalar multiplication.

Each entry/element of the matrix is multiplied by the specified scalar in scalar multiplication. Comparatively, matrix multiplication describes the result of two matrices. This operation is totally different. We can't just multiply the corresponding entries in two matrices to multiply them.

The first matrix must have exactly as many columns as the second matrix has rows in order to perform matrix multiplication. The resulting matrix has the same number of columns and rows as the second matrix, and its number of columns matches the number of rows in the first matrix.

Given:

The area model.

To find:

The area as a sum and area as a product.

Solution:

The four terms of the area model are \(2x^2,10x, 3x, 15\).

The area as a sum is the sum of all the terms of given area model.

Area as a sum = \(2x^2+10x+3x+15\)

                        = \(2x^2+13x+15\)

The area as a product is the factor form of sum of all the terms of given area model.

Area as a product = \(2x^2+10x+3x+15\)

                        = \(2x(x+5)+3(x+5)\)

                        = \((x+5)(2x+3)\)

Therefore, the area as a sum is \(2x^2+13x+15\) and the area as a product is \((x+5)(2x+3)\).

Answer: \(y-1=\dfrac32(x+3)\)

Step-by-step explanation:

Slope of a line passes through (a,b) and (c,d) = \(\dfrac{d-b}{c-a}\)

In graph(below) given line is passing through (-2,-4) and (2,2) .

Slope of the given line passing through (-2,-4) and (2,2) =\(\dfrac{-4-2}{-2-2}=\dfrac{-6}{-4}=\dfrac{3}{2}\)

Since parallel lines have equal slope . That means slope of the required line would be .

Equation of a line passing through (a,b) and has slope m is given by :_

(y-b)=m(x-a)

Then, Equation of a line passing through(-3, 1) and has slope =  is given by

\((y-1)=\dfrac32(x-(-3))\\\\\Rightarrow\ y-1=\dfrac32(x+3)\)

Required equation: \(y-1=\dfrac32(x+3)\)

Answer: Slope is 1/2

Step-by-step explanation:

We can write this slope intercept form

y=mx+b

m=slope

b=y-intercept

The Y-intercept is (0,2) on the line

the slope is 1/2

You get the slope by starting at the point (0,2) and going over to the next point on the line which is (2,3)

Now let's look at how we got there, we went up one time and right two times, giving us 1/2

In slope intercept form it would be y=1/2x+2

THE SLOPE IS 1/2

Answer:

There are 68,640 different ways the runners can finish first, second, and third in the race.

Concept of Permutations

The number of different ways the runners can finish first, second, and third in a race can be calculated using the concept of permutations.

Brief Overview

Since there are 42 runners competing for the top three positions, we have 42 choices for the first-place finisher. Once the first-place finisher is determined, there are 41 remaining runners to choose from for the second-place finisher. Similarly, once the first two positions are determined, there are 40 runners left to choose from for the third-place finisher.

Calculations

To calculate the total number of different ways, we multiply the number of choices for each position:

42 choices for the first-place finisher × 41 choices for the second-place finisher × 40 choices for the third-place finisher = 68,640 different ways.

Concluding Sentence

Therefore, there are 68,640 different ways the runners can finish first, second, and third in the race.

The least volume of 6.0 M HCl needed to dissolve the excess Mg is 0.028 L.

Calculate the moles of Mg and CuSO4:

Moles of Mg = (0.832 g) / (24.305 g/mol) = 0.0342 mol

Moles of CuSO4 = (1.794 g) / (159.609 g/mol) = 0.0112 mol

Determine the limiting reactant:

The mole ratio between Mg and CuSO4 is 1:1. Since the moles of CuSO4 (0.0112 mol) are less than the moles of Mg (0.0342 mol), CuSO4 is the limiting reactant.

Calculate the moles of excess Mg:

Moles of excess Mg = Moles of Mg - Moles reacted with CuSO4

= 0.0342 mol - 0.0112 mol = 0.0230 mol

Convert moles of excess Mg to grams:

Mass of excess Mg = Moles of excess Mg × Molar mass of Mg

= 0.0230 mol × 24.305 g/mol = 0.559 g

Determine the volume of 6.0 M HCl needed to dissolve the excess Mg:

Use the balanced chemical equation:

Mg + 2HCl → MgCl2 + H2

The stoichiometric ratio between Mg and HCl is 1:2. Therefore, the moles of HCl required will be twice the moles of excess Mg.

Moles of HCl required = 2 × Moles of excess Mg = 2 × 0.0230 mol = 0.0460 mol

Concentration of HCl = 6.0 M, so:

Volume of HCl (L) = Moles of HCl required / Concentration of HCl

= 0.0460 mol / 6.0 mol/L = 0.00767 L = 0.00767 × 1000 mL = 7.67 mL

Therefore, the least volume of 6.0 M HCl needed to dissolve the excess Mg is 7.67 mL.

Answer: 3 1/5

Step-by-step explanation:

The volume of Cone A is 100π cubic ft.

The formula to calculate the volume of a cone is V = (1/3)*π*r²*h, where r is the radius and h is the height of the cone.

If we double the radius and the height of a cone, the volume of the cone will increase four times. Mathematically, this can be shown using the formula. If we double both the radius and the height, the volume will become (1/3)*π*(2r)²*(2h) which simplifies to (1/3)*π*4r²*2h. This simplifies further to 4*(1/3)*π*r²*h which is equal to 4*V, where V is the original volume of the cone.

In the given question, the volume of Cone B is 25π cubic ft. If we double the radius and the height of Cone B, the volume of Cone A will be 4*25π cubic ft or 100π cubic ft.

The value of a for which v is a linear combination is given as follows:

a = -8.

How to obtain the value of a?

A vector generated by adding two or more vectors (with various orientations) and multiplying by scalar values is known as a linear combination of two or more vectors.

v will be a linear combination of the set H if it can be obtained as the solution of a system of equations from the set H.

From the vectors, the system is defined as follows:

-x = -1.

2x - y = 4.

5x + 4y - 3z = -6.

-x + 3y - z = a.

From the first equation, the value of x is obtained as follows:

-x = -1

x = 1.

From the second equation, the value of y is obtained as follows:

2x - y = 4

2 - y = 4

y = 2 - 4

y = -2.

From the third equation, the value of z is obtained as follows:

5x + 4y - 3z = -6.

5 - 8 - 3z = -6

3z = 3

z = 1.

Then the value of a needed for the linear combination is of:

a = -x + 3y - z

a = -1 - 6 - 1

a = -8.

Multiple Choice= 2 points each

Short Response= 4 points each

Step-by-step explanation:

You can set up a system of equations to find out how many points each type of question is worth.

x= multiple choice

y= short response

Equation 1 (You)

23x+10y=86

Equation 2 (Your Friend)

28x+5y=76

Solve with elimination. Multiply the second equation by negative 2 to cancel out the y-variable.

-2(28x+5y=76)

-56x-10y=-152

Subtract both equations together.

23x+10y=86

-56x-10y=-152

-33x= -66

x=2

Now that we found x, plug it into the first equation to solve for y.

23x+10y=86

23(2)+10y=86

46+10y=86

10y=40

Step-by-step explanation:

Answer:

the correct graph is A

Step-by-step explanation:

Note that the red line passes through (0, 2), which is the y-intercept, b, in y = mx + b.  Thus the correct answer must be A or B, not C or D.

Besides (0, 2), another point on this line is (1, 3).

The increase in x going from 0 to 1 is 1; this is the 'run'.  That in y going from 1 to 3 is 2; this is the 'rise.'  Therefore the slope is m = rise / run = 2/1 = 2.

Thus the correct graph is A; its slope is 2 and its y-intercept is 1.

The probability that either the words BAD or CAB will appear as part of the row  is 16.7%

We have 4 places where we can put the cards.

Let's count the number of possible outcomes for each place.

In the first place, we can put one of 4 cards.

In the second place, we can put one of 3 cards (because one card was taken in the first place).

In the third place, we can put one of 2 cards

In the last place, we can put one of one cards.

The total number of different combinations is the product between the number of options for each place, then we have:
