Solve 5(x + 2) = 26 - 3x
x = ...

The missing co-ordinate r = 8

(6,9) and (r,-1) are two points on a line whose slope is given as -5.

Slope of a line is the change of y co-ordinates divided by the change in x co-ordinates between two points on a line.

Take (x₁, y₁) = (6,9) and (x₂, y₂) = (r, -1).

The slope of a line is given by,

Slope, m = (y₂-y₁)/ (x₂-x₁)

⇒  -5 = (-1-9)/(r-6)

⇒ -5 = -10/(r-6)

⇒ 1 = 2/(r-6)

⇒ r-6 = 2

⇒ r = 2+6

⇒ r = 8

So the points are (6,9) and (8,-1).

10,000=100x100

The remainder of the given division ( x³+5x²−32x−7 ) ÷ ( x−4 ) is equal to 9.

As given in the question,

Dividend of the given division is equal to :  ( x³+5x²−32x−7 )

Divisor of the given division is equal to : ( x−4 )

Divide the given dividend ( x³+5x²−32x−7 ) by divisor  ( x−4 ) remainder we get,

( x³+5x²−32x−7 )

= x³ -4x² +9x² -36x +4x-16 +9

= x²(x-4) + 9x (x-4) +4(x-4) + 9

= (x-4)(x² +9x +4) + 9

Quotient is equal to (x² +9x +4)

Remainder is equal to 9

Therefore, the remainder of the given division ( x³+5x²−32x−7 ) ÷ ( x−4 ) is equal to 9.

If the company earned a total of $37,500 in interest last year, how much cash did they keep in the bank is; $937,500.

This is about the concept of compound interest which is defined as the interest on savings that is calculated on both the initial principal and the accumulated interest from previous periods.

From the question, let us make x to represent the amount of cash.

Now, we are told that one portion of it pays 0.5%and as such this will be 0.005x.

Now, the other portion pays 3.5% and as such this is 0.035x.

Combining both knowing that the total the company earned in the last year was $37,500 and we have;

0.005x + 0.035x = 37500

0.040x = 37500

Solve for x to get;

x = (37500)/(0.04)

x = 937500

Therefore, the company started with $937,500.

The standard equation is 7x + y = 9

layoff Ax + By = C is the usual form for two-variable direct equations. A standard form direct equation is, for case, 2x + 3y = 5. When an equation is given in this format, chancing both intercepts is rather simple( x and y). When trying to break systems involving two direct equations, this form is also relatively helpful.

Given

7x + 3 = 5 and y - 1 = 6

Add the bottoms from the two given equations to produce a single standard-form equation.

By shifting the constant fromR.H.S. toL.H.S., the equations are reset to zero.

7x + 3 - 5 = 0

7x - 2 = 0----( 1)

y - 1 = 6

y - 1 - 6 = 0

y - 7 = 0-----( 2)

Equation 1 and equation 2 must be combined.

7x - 2 + y - 7 = 0

7x + y - 9 = 0

layoff Ax + By = C is the equation's conventional form.

A, B, and C are integers and x and y are variables in this type of equation.

Accordingly, the common equation is

7x + y - 9 = 0

7x + y = 9

therefore the standard equation is 7x + y = 9

Answer: Around 10 sixth graders would get free lunch.

Step-by-step explanation: first, divide 500/25 to find the percentage of students receiving free lunches. You should get 0.05, or 5%. Then, multiply the number of sixth graders (203) by 5%. Your answer is 10.15, rounded down to 10. (Because it is impossible to have 0.15 of a student)

The amount of interest would be $8.4 Charis received at the end of two years.

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100

We have been given data as:

Principal (P) = $140

Rate of Interest (R) = 3% = 3/100 = 0.03

Time (T) = 2 years

⇒ Simple interest  = P × R × T

Substitute the value of P, R, and T in the above formula,

⇒ Simple interest = 140 × 0.03 × 2

⇒ Simple interest = $8.4

Therefore, the amount of interest would be $8.4 Charis received at the end of two years.

The relation that represents a function is the mapping in: B.

A relation is defined as a function if each of the x-value (domain element of input) in the relation corresponds to exactly one y-value (range element of output).

The relation in option A is not a function because it has two different y-values, 7 and 5 that corresponds to an x-value, 6. The relations in option C and D do not represent a function also.

The mapping in option B shows a relation where each x-value (domain element) is related or corresponds to only one y-value (range element). Therefore, it is a function.

Answer:

A = 15

B = 3

Step-by-step explanation:

Since Team A has 12 more points than team B, then,

A - 12 = B

A = B + 12 ( equation 1 )

team A has 5 times as many points as team B, so,

5B = A. ( equation 2 )

Substitute equation 1 into equation 2

A = B + 12

5B = B + 12

5B - B = 12

4B = 12

B = 3

we'll substitute the answer into equation 2

5B = A

5(3) = A

A = 15

The above statement can be rewritten in another way

So, we have the following equation

1/10^5 = 10^5

As a general rule of indices, we have the following exponent rule

So, we have the following equation

1/a^n = a^-n

[tex]\frac{-6}{10}[/tex] + [tex]\frac{-7}{10}[/tex]

A fraction is written with a numerator and a denominator where the numerator is less than the denominator.

Example: 1/3 is a fraction

We have,

[tex]\frac{-3}{5}[/tex] + [tex]\frac{-7}{10}[/tex]

We have different denominators and we need to make the denominator the same.

We will multiply 2 on both the numerator and denominator of  [tex]\frac{-3}{5}[/tex].

= [tex]\frac{2 \times -3}{2 \times 5}[/tex]

= [tex]\frac{-6}{10}[/tex]

We see that,

The denominator in [tex]\frac{-6}{10}[/tex]  and [tex]\frac{-7}{10}[/tex]  is the same.

i.e 10.

Now,

[tex]\frac{-3}{5}[/tex] + [tex]\frac{-7}{10}[/tex] can be written as [tex]\frac{-6}{10}[/tex] + [tex]\frac{-7}{10}[/tex]

The rate of change in enrollment from 2010 to 2020 is -53 students per year.

Interpretation:

A negative rate of change (-53 students per year) means that the enrollment in the school decreased over the 10-year period from 2010 to 2020. On average, the school lost 53 students per year during this time frame. This decline in enrollment may have implications for the school's resources, budget, and programs, as it indicates a reduction in the student population over the given period.

Here, we have,

To find the rate of change in enrollment from 2010 to 2020, we can use the formula for calculating the rate of change:

Rate of change = (Change in enrollment) / (Time interval)

Where:

Change in enrollment = Enrollment in 2020 - Enrollment in 2010

Time interval = Year in 2020 - Year in 2010

Let's calculate the rate of change:

Change in enrollment = 715 - 1245 = -530

Time interval = 2020 - 2010 = 10 years

Rate of change = (-530) / 10 = -53

The rate of change in enrollment from 2010 to 2020 is -53 students per year.

Interpretation:

A negative rate of change (-53 students per year) means that the enrollment in the school decreased over the 10-year period from 2010 to 2020.

Find the volume of the metal as following:

Find the mass:

Answer:

Step-by-step explanation:

Volume of a cylinder

[tex]V=\pi r^2 h[/tex]

where:

The radius of a circle is half its diameter.

Find the volumes of the external and internal cylinders by substituting the given values into the formula for volume of a cylinder:

[tex]\implies \textsf{Volume of the external cylinder}&=\pi \cdot 5^2 \cdot 16=400 \pi \; \sf cm^3[/tex]

[tex]\implies \textsf{Volume of the internal cylinder}&=\pi \cdot 4^2 \cdot 16=256 \pi \; \sf cm^3[/tex]

Find the volume of the cylindrical hollow metal pipe by subtracting the volume of the internal cylinder from the volume of the external cylinder:

[tex]\begin{aligned}\implies \textsf{Volume of the metal pipe}&=\sf Volume_{external}-Volume_{internal}\\&=400 \pi - 256 \pi\\& = 144 \pi \sf \; cm^3\end{aligned}[/tex]

Density formula

[tex]\rho=\dfrac{m}{V}[/tex]

where:

Given:

Substitute the given values of density and the found volume into the density formula and solve for m:

[tex]\begin{aligned}\implies \rho&=\dfrac{m}{V}\\8&=\dfrac{m}{144 \pi}\\m&=8 \cdot 144\pi\\m&=1152 \pi \\m&=3619.11473...\\m&=3619.1\; \sf g \;(nearest\;tenth)\end{aligned}[/tex]

An equation is a mathematical statement that is made up of two expressions connected by an equal sign. For example, 3x – 5 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 7.

Let the number of seats in Section A is "a".

Let the number of seats in Section B is "b".

and, Let the number of seats in Section C is "c".

Now using the statement "stadium has 52,000 seats"

we can make equation: a + b + c = 52000  

Now using the statement "Seats sell for $28 in Section A, $24 in Section B, and $20 in Section C" and "stadium takes in$1,307,200 from each sold out event".

we can make equation: 28a + 24b + 20c = $1,307,200

Now using the statement "he number of seats in Section A equals the total number of seats in Sections b and C"
