-(x − 1) + 10 = -3(x - 2)​

Answers

Answer 1

According to the question, the solution to the equation is x = -7.

What is the equation ?

The equation is a representation of a mathematical relation between two or more variables. It is usually expressed as an equation, where one side of the equation is equal to the other. For example, the equation y=mx+b is a linear equation with two variables, m and b, which are known as the slope and the y-intercept, respectively.

To solve this equation, we must first combine like terms on both sides of the equals sign.

-3x + 3 - x + 10 = -3x + 6

Next, we can subtract 3 from both sides of the equation to isolate the x-term.

-4x + 13 = -3x + 6

Finally, we can subtract -3x from both sides of the equation to isolate the constant term.

-7x = 7

We can then divide both sides of the equation by -7 to solve for x.

x = -7

Therefore, the solution to the equation is x = -7.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

To produce each product unit, the company spends $1.75 on material and $2.95 on labor. Its total fixed cost is $6000. Each unit sells for $6.35.

Let 'x' be the number of units. Then the equation is given as,

6.35x = 1.75x + 2.95x + 6000

Simplify the equation, then we have

6.35x = 1.75x + 2.95x + 6000

6.35x = 4.7x + 6000

=========================================

Work Shown:

[tex](7+3)^2+(14+12\div 6)\\\\(7+3)^2+(14+2)\\\\(10)^2+(16)\\\\100+16\\\\116\\\\\text{Therefore, }(7+3)^2+(14+12\div 6) = 116[/tex]

----------

Explanation:

We use the order of operations PEMDAS.

P = parenthesisE = exponentsM = multiplicationD = divisionA = additionS = subtraction

Parenthesis go first, so we evaluate each expression separately in the two parenthesis groupings.

In the second group, we have [tex]14+12\div6[/tex]. The [tex]12\div6[/tex] portion goes before addition. This is because division ranks higher than addition in PEMDAS shown above.

So this is why [tex]14+12\div6[/tex] becomes [tex]14+2[/tex]

After that we add up the stuff in the parenthesis to end up what is shown in the third step.

Then we square the 10 to get 100. The last step is to then add 100 to 16 to get 116 as the final answer.

You can type the original expression into a calculator to confirm the answer. Your calculator should have a division button labeled [tex]\div[/tex] but if not, then look for the slash symbol. Example: [tex]12 \div 6 = 12/6 = 2[/tex]

If I've already taken out two pieces that don't directly connect, what is the minimum number of additional pieces that I need in order to guarantee that the original two pieces connect?

Answers

Answer:

To guarantee that the two pieces you've already taken out connect, you'll need to take out at least four additional pieces. This is because the two pieces you've already taken out will each need to connect to two other pieces, so you'll need four pieces to make two connections. It's possible that fewer pieces might be required, but this is the minimum number of pieces that you need to guarantee the connection.

What is Expression?

An expression is combination of variables, numbers and operators.

The exponential decay function to model the situation is f(x)=52(0.8)ˣ

where 52 is the initial value and 0.8 is the decay factor.

The given intervals are 1≤x≤5

f(1)=52(0.8)=41.6

f(5)=52(0.8)⁵=17.039

The average rate=17.039-41.6/5-1

=24.561/4

=6.140

Now let us find for the interval 6≤x≤8

f(6)=13.631

f(8)=8.724

Average rate=8.724-13.631/8-6

=-2.453

The rectangle QRST have the values for the respective angles and lengths as: m∠QRS = 90°, m∠QTR = 42°, m∠RTS = 48°, TR = 16, and QU = 8.

Diagonals of rectangle

A rectangle has two diagonals that are the same(congruent) and they bisect each other. The rectangle have two pair of parallel sides which makes the angles formed by its diagonals alternate angles. And each interior angle of the rectangle is equal to 90°

m∠QRS = 90° {an angle of a rectangle}

m∠QTR and m∠TRS are alternate angles and are equal so;

m∠QTR = 42°

m∠RTS and m∠QTR are complementary angles are they sum up to 90° so;

m∠RTS = 90° - 42°

m∠RTS = 48°

lines TR and QS are diagonals of the rectangle and are equal so;

TR = 16

line segment TR bisect QU so;

QU = 16/2

QU = 8.

When taking out a loan, the borrower must provide collateral such as a car or home to reduce the risk to the lender and increase the chances of the loan being approved. This includes rent, monthly bus pass, savings, student loan payment, and other expenses.

What do you mean by loan?

A loan is a type of debt that is typically provided by a financial institution such as a bank, credit union, or finance company. The purpose of a loan is to provide the borrower with a large sum of money that they may not have readily available, which they must then pay back over a set period of time with interest.

There are various types of loans, including personal loans, car loans, home loans, and student loans. Personal loans are unsecured loans that can be used for a variety of purposes, such as debt consolidation or home improvement. Car loans are used specifically to purchase a vehicle, while home loans are used to purchase a home. Student loans are designed to help pay for education expenses.

When taking out a loan, the borrower is typically required to provide some form of collateral, such as a car or a home, to secure the loan. This helps to reduce the risk to the lender and increases the chances of the loan being approved.

1. Rent: 30% of $3,850 = $1,155.

To solve for x in the equation 16^x + 3 = 4^ (x+1), follow these steps:

Isolate the x terms on one side of the equation by subtracting 3 from both sides:
16^x + 3 - 3 = 4^ (x+1) - 3
16^x = 4^ (x+1) - 3
Take the logarithm of both sides to get rid of the exponential functions:
log16 (16^x) = log16 (4^ (x+1) - 3)
x = log16 (4^ (x+1) - 3) / log16 (16)
Use the logarithmic identity logb (a^c) = c * logb (a) on the right side:
x = (x + 1) * log16 (4) / log16 (16)
Simplify the right side by using logarithmic identities:
x = (x + 1) * log16 (2^2) / log16 (2^4)
x = (x + 1) * 2 / 4
Solve for x by dividing both sides by x + 1 and multiplying by 4:
x * 4 / (x + 1) = 2
4x = 2x + 2
2x = 2
x = 1

The parametric equations are therefore: x is t, y is 1/3 * t, and z is t.

What is  parametric equations?

Response: x = t; y = 1/3; t; z = t

Given

At t = 0, r(t) equals f(t) * I + g(t) * j + h(t) * k.

(F (t0), G (t0), and H (t0))

r(t) = ln (t - 1) + (t + 2) * j + t * ln(tk) t * t * 0 = 1 Required Information is Missing

Calculate the parametric equations.

j + t * ln + (t - 1)/(t + 2) * ln + r(t) = ln(ti) (tk)

With regard to t, differentiate (t) = 1/t * I + 3/((t + 2) 2) * j + (ln(t) + 1) Let t=1 (i.e., e * t * t * 0 = 1)

r = 1/1 for prime (1). * I + 3/((1 + 2) ^ 2) * j + (ln(1) + 1) I + 3/(3 2) * k r prime (1) * j + (0 + 1) Prime (1) = I + 3/9 * K R * j + (1) (1) Prime (1) = I + 1/3 * j + * k r (1) I + 1/3 * j + k = * k r prime (1)

To find x, y, and z.

We utilise the following methods to find x, y, and z: r(t) = f(t) (t) * j + h (t) * k + I + g (t)

This suggests that:

prime r (1) * T = xi, yj, and zk

We therefore have:

I + 1/3 * j + k) = xi + yj + zk * t

it + 1/3 * jt + kt = xi + yj + zk.

In contrast:

xi = it

Divide by I x, y, and j to get 1/3 * jt.

Divide by j y = 3/9 * t zk = kt

Divided by k, z equals t.

What is a frequency table ?

A frequency table consists of the lists of items in a given data set and the number of times each item occurs in the data set and The number of times a particular data value occurs in a given data set is referred to as its frequency.

e.g.

A, A, A, B, B, B, B, C, C, D

Count the number of times each grade occurs in the above series. Yes, ‘A’ occurs thrice, ‘B+’ occurs four times, ‘C’ occurs twice, and ‘D’ occurs once. Now, according to the definition of frequency, we can note the frequency of each grade as follows:

Frequency of A = 3

Frequency of B = 4

Frequency of C = 2

Frequency of D = 1

Let us list the grades obtained by the students in the above example, in a frequency table. Table is in image.

Now,

For given frequency table

Mean=sum of all values/no. of terms=2864/50=57.28

Mode=63 as the frequency is highest for 63

Median=(25th+26th) terms/2=61.5.

Hence,

           mean=57.28, mode=63 and meadian=61.5.

let have the following distribution: 1 2 3 4 0.2 0.3 0.1 0.4 find (2x^2 3x) (write it up to first decimal place).

Answers

For the given distribution, the Expectation, E(2X² + 3X) is 28.9

Now here we see that we have the distribution given to us

We need to find

E(2X² + 3X)

Now we know that

E(X) = ∑xp(x)

Hence we get

E(2X² + 3X) = 2[1 X 0.2  +  4 X 0.3  +  9 X 0.2  +  16 X 0.4] + 3[1 X 0.2  +         2 X 0.3  +  3 X 0.2  +  4 X 0.4]

= 2[0.2 + 1.2 + 1.8 + 6.4] + 3[0.2 + 0.6 + 0.6 + 1.6]

= 2 X 9.6  +  3 X 3

= 19.2 + 9

= 28.9
