Step-by-step explanation:

rewriting the third equation

[tex]4x - y + z = - 5 \\ - x + y - z = 5 \\ 2x - y - z = 1[/tex]

add to second equation to the first

[tex]4x - y + z = - 5 \\ + (- x + y - z )= 5 \\ = 3x = 0 \\ x = 0[/tex]

[tex] - y + z = - 5 \\ y - z = 5 \\ - y - z = 1[/tex]

I add third equation to the second

[tex]y - z = 5 \\ + ( - y - z) = 1 \\ = - 2z = 6 \\ z = - 3[/tex]

substitute z = -3 into either one of the other two equations and solve for y

[tex] - y + ( - 3) = - 5 \\ - y - 3 = - 5 \\ - y = - 2 \\ y = 2[/tex]

x = 0

y = 2

z = -3

x=0,z=-3,y=2

Since a > 1, b cannot be greater than 15, hence the value of a can be 3, 4, 5, and 10

Given the expression 15x + 20=a(bx + c),

To get the value of a, we will need to factor out the given expression as shown:

15x + 20=a(bx + c)

15x + 20=abx + ac

Comparing both sides

15x = abx

15 = ab

a = 15/b

Since a > 1, b cannot be greater than 15

Hence the value of a can be 3, 4, 5, and 10

Answer:

4

Step-by-step explanation:

Do you see f(x) (f of x)? if the (x) part is a number, plug that number in as x on the other side of the equal sign. If I plug 1 in, I get 4, because the square root of 1 is 1, and 1+3=4.

Answer:

See explanation!

Step-by-step explanation:

The contrapositive of a conditional is similar to, yet different from, the inverse of the conditional.

The best way to explain this is to create an example. You should start by creating a conditional; you can then form the conditional's inverse and contrapositive.

Here is an example:

Conditional: If C, then D. (starting statement)

Inverse: If not C, then not D. (opposite of the conditional)

Contrapositive: If not D, then not C. (reversed opposite of the conditional)

Based on the information from the example, you can conclude:

Primary Similarity:

Both the contrapositive and the inverse are opposites of the conditional (both contain not, implying something would not happen under the given circumstances, rather than something would happen under those circumstances).

Primary Difference:

The contrapositive is a reversed version of the inverse; this causes them to most commonly have different meanings.

I am sure you could find more similarities/differences, but these were the two that stood out to me the most!

Answer:

Step-by-step explanation:

The easy way is to compare the leading terms or constants.

The leading term is:

The constant is:

The leading term is:

The constant is:

We see both the leading terms (10x³ ≠ 15x³) and constants (-18 ≠ -12) are different so the equation is false.

We see one of the factors is same on both sides:

The other factors are:

Since this factor is different on both sides, the equation is false

Answer:

inequality: n/4 < -1

n < -4

Step-by-step explanation:

1. "The quotient of a number and 4" means that we're dividing a number, n, by 4: [tex]\frac{n}{4}[/tex]. "Less than -1" means that we have to use the < (less than) sign and put -1 after it. When we put these terms in a quantity, they look like this: [tex]\frac{n}{4} < -1[/tex].

2. Now, let's solve the inequality above.

Step 1: Multiply both sides by 4.

Therefore, the inequality is n/4 < -1, and the solution to that inequality is n < -4.

Answer:

Domain: {x∈R}

Range: {f(x)∈R | f(x) ≥ 0}

Step-by-step explanation:

The domain of a function is, in simple terms, all the possible x values of a function (input values), and as the graph shows that all x values are possible (x, 0 and -x) meaning x can be any rational number, represented by the R and the subset symbol (∈).

The range is all the possible f(x) values (outputs/y values) and if you look at the graph you see that it isn't possible for the f(x)/output/y values to be negative so we write:

{f{x}∈R (f(x)/output/y value is rational) | (and) f(x) ≥ 0 (f(x)/output/y value is bigger or equal to 0, not negative)}

Answer:  Natasha = 480; Richard = 240, Stephen = 80

Step-by-step explanation:

Let N, R, and S stand for the amounts Natasha, Richard and Stephen receive.  The problem tells us that:

N = 2R, and

R = 3S

We know that N+R+S = 800

Since N=2R and R=3S, N = 6S

N+R+S = 800

6S+3S+S=800

10S=800

S=80

R=3S or 240

N=2R or 480

Conclusion:

N gets 480

R gets 240,

and S gets 80

That adds to 800.

. . .  AND the last conclusion is that I need to meet Natasha.  Please send Stephen home.

Step-by-step explanation:

5x(x−2)+6x−3(x^2−7) = 2x^2 - 4x + 21

0 = 0

I used a calculator, pls let me know if im incorrect

The given expression 5x(x−2)+6x−3(x²−7) will be equivalent to 2x²- 4x + 21. The correct option is D.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is 5x(x−2)+6x−3(x²−7). The expression will be solved as below:-

E = 5x(x−2)+6x−3(x²−7)

E = 5x² - 10x + 6x - 3x² + 21

E = 2x² - 4x + 21

Therefore, the given expression 5x(x−2)+6x−3(x²−7) will be equivalent to 2x²- 4x + 21. The correct option is D.

Answer: 1953

Step-by-step explanation: You need to subtract 7768 and 7117 to find the average change in 2 years; you get 651, divide this by 2 to find the amount of change in 1 year and you'll get 325.5, now if we take 325.5 times 6 (the amount of years until 2016) you will find 1953 as the answer.

Answer:

a) 3/12 = 1/4

b) 6/12 = 1/2

c) 9/12 = 3/4

Step-by-step explanation:

To find the distance traveled by the hour hand, subtract the beginning position from the ending position. For example, in a, the distance traveled between 4:00 and 7:00 is three hours. Since there are 12 total hours on a clock, the fraction would be 3/12 (traveled/whole revolution). Simplify further to get 1/4.

The other two problems are very similar to the explanation above. Treat the second problem's ending time as 14:00, since it is two hours after 12:00.

The possible value of x is -66

The given parameters are:

[tex]\mathbf{S = (-6,8)}[/tex]

[tex]\mathbf{T = (x,-3)}[/tex]

[tex]\mathbf{ST = 61}[/tex]

Distance ST is calculated using:

[tex]\mathbf{d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}}[/tex]

So, we have:

[tex]\mathbf{d = \sqrt{(-6 - x)^2 + (8 - -3)^2}}[/tex]

[tex]\mathbf{d = \sqrt{(-6 - x)^2 + (8 +3)^2}}[/tex]

[tex]\mathbf{d = \sqrt{(-6 - x)^2 + 11^2}}[/tex]

Substitute 61 for d

[tex]\mathbf{ \sqrt{(-6 - x)^2 + 11^2} = 61}[/tex]

Square both sides

[tex]\mathbf{ (-6 - x)^2 + 11^2 = 61^2}[/tex]

[tex]\mathbf{ (-6 - x)^2 + 121 = 3721}[/tex]

Subtract 121 from both sides

[tex]\mathbf{ (-6 - x)^2 = 3721 - 121}[/tex]

[tex]\mathbf{ (-6 - x)^2 = 3600}[/tex]

Take square roots of both sides

[tex]\mathbf{ -6 - x = 60}[/tex]

Add 6 to both sides

[tex]\mathbf{ - x = 60 + 6}[/tex]

[tex]\mathbf{ - x = 66}[/tex]

Multiply both sides by -1

[tex]\mathbf{ x = -66}[/tex]

Hence, the possible value of x is -66
