The solution to the system of equations is ( -2, 0)

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant.

y = -2x - 4 ------------1

y = x + 2--------------2

Equating equation 1 and 2 we have

-2x - 4 = x + 2

collect like terms

-2x - x = 2 + 4

-3x = 6

x = 6/-3

x = -2

but y = x + 2

substitute x = -2

y = -2 + 2, y = 0

In conclusion the solution of the system of linear equations is (-2, 0 )

Answer:

x^3y^2√xy

Step-by-step explanation:

First, you calculate what's in the square root. x^2 becomes x and y^4 becomes y^2.

Then you distribute the 1/2 to the x^5 and the y so they become x^5/2 and y^1/2.

Next, you combine the like terms. x and x^5/2 becomes x^7/2. y^2 and y^1/2 become y^5/2.

So you have x^7/2 y^5/2

To get rid of the 2 on the bottom of the exponents you square root both variables.

So you get √x^7 y^5 (square rooted x^7 and y^5)

Simplify the square rooted problem to x^3 y^2 √xy

You get x to the third power y to the second power and square rooted xy.

The actual quotient and the estimated quotient of 78,070÷37 is 2110 , so the difference between them is 0.

On dividing 78,070 by 37 ,

we get

78,070 /37

=2110

Since , the number gets divided completely

therefore the estimated quotient and the actual quotient will be 2110.

We first round the dividend and the divisor to the closest tens, hundreds, or thousands, and then divide the rounded figures to approximate the quotient. When the divisor in a division sum has two or more digits, it is helpful to first estimate the quotient before attempting to discover the exact number.

The outcome of dividing two numbers is known as the quotient. Divided divisor = quotient + remainder is the formula for expressing the terms of division.

The required factors of the given polynomial is (r^4 + rs^5)(t^8 - (rs^5t^4) + r^2s^10).

A factor  is a number that partitions another number, leaving no remainder portion.  if multiplying two whole number gives us an item, the numbers we are increasing are variables of the item since they are separable by the item.

We have given,

t^12 - r^3(s)^15

By using formula

(a³ - b³) = ( a+ b)( a² -ab + b²)

Then,

(r^4)^3 - (rs^5)^3

(r^4 + rs^5)((t^4)^2 - rs^5t^4 + (r^5)^2)

(r^4 + rs^5)(t^8 - (rs^5t^4) + r^2s^10)

Thus, required answer is (r^4 + rs^5)(t^8 - (rs^5t^4) + r^2s^10), So option (D) is correct.

Answer:

the answer to this should be no solution

Step-by-step explanation:

the first step would be adding seven to both sides, but all that does is leave a zero on the other side, so the equation ends up being 9x=0.

The value of x in the expression is 0.

We have,

Expression: 9x - 7 = -7

To solve for x.

Add 7 on both sides.

9x - 7 + 7 = -7 + 7

9x = 0

x = 0

Thus,

The range of the function f(x) = 3x - 4, having domain x ≥ 1 is x ≥ -1 and the graph is attached below so, option D is correct.

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

Given:

The function, f(x) = 3x - 4,

Domain = x ≥ 1

When domain = 1,

Range = 3 × 1 - 4 = -1

When domain = 2

Range = 3 × 2 - 4 = 2

Rounding to the nearest tenth, we get that the length of KN is approximately 21.8.

What is a Pythagoras theorem?

The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This relationship is often expressed in the form of the equation:

a² + b² = c²

To find the length of KN in this right triangle, you can use the Pythagorean theorem. This theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, the hypotenuse is KL, and the other two sides are KM and KN. The theorem can be written as:

KL² = KM² + KN²

Substituting the given values, we get:

24² = 10² + KN²

Solving for KN, we get:

KN² = 24² - 10²

= 576 - 100

= 476

KN = √476

= 21.84

Hence, rounding to the nearest tenth, we get that the length of KN is approximately 21.8.

The calculated value of the rocket's greatest height is 196 feet

From the question, we have the following parameters that can be used in our computation:

height function,  h(t) =-16t² + 80t + 96

So, we have

h(t) =-16t² + 80t + 96

The maximum value of t is calculated as

t = -b/2a

So, we have

t = -80/(2 * -16)

Evaluate

t = 2.5

The rocket's greatest height is at t = 2.5

So, we have

h(2.5) =-16(2.5)² + 80(2.5) + 96

h(2.5) = 196

The value of f(-7) is -29.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

f(x)=-x² + 2x + 6

interest = 0.66% per day

t = 57 days

There were 1080 seats in the theater.

In this question, we have been given that the 6th grade students went on a field trip to see a ballet.

The students filled 702 seats leaving 35% vacant.

We need to find the total seats in the theater.

Let there were n seats in the theater.

Given that 35 percent of total seats were vacant.

So, we get an equation,

702 + (35% of n) = n

702 + 0.35n = n

(1 - 0.35)n = 702

0.65n = 702

An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.

Given:

y =x³-4x²-17x+60x

Let us assume that the factors are

(x−a), (x−b) and (x- c)

So, if x is either equal to a or b or c, y=0

and a⋅ b⋅ c=−60, which means a or b and c are factors of 60.

Thus, which factor of 60 (such as 2, 3, 5, 6, 10 etc.) makes y=0.

It is given that (x−3) is a factor of y

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

___ R ___ B ___ G ___ Y

R_ RR __ RB __ RG __ RY

B_ BR __ BB __ BG __ BY

G_ GR __GB __ GG __GY

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                                  Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

They need at least 100 pieces of sushi

Sofia had ordered and paid for 24 pieces of sushi already

Sushi comes in rolls

Each roll=12 pieces at $8

R=additional rolls that Sofia orders

Additional sushi= Needed sushi - ordered sushi

=100-24

=76 pieces of sushi

Each roll has 12 pieces

76/12=6.33

Sofia has to order in rolls

So, she will order 7 more rolls of sushi of 12 pieces each

12*7=84 pieces

Recall, that they needed at least 100 pieces, so the number of pieces could be more than 100
