Answer:

(-2,3) or x= -2 and y= 3

Step-by-step explanation:

I didn't graph this, but you could.

For the first equation: Subtract x from both sides to get 2y= -x +4

Next divide both sides by 2 to get y= -1/2x + 2 (Now graph this)

For the second equation subtracted both sides by -3x to get 2y= -3x

Next, divide both sides by 2 to get y= -3/2x (Now graph this)



I used elimination. I wrote both equations out then subtracted 2y from both of them then did -2x = 4

x= -2

then I substitued -2 + 2y = 4

6  = 2y

y=3

A basis of R3 cannot have more than 3 vectors, because any set of 4 or more vectors in R3 is linearly dependent.

Vectors v1, v2, . . . , v k ∈ V is called linearly dependent if they satisfy a relation of:

r₁v₁+r₂v₂+ · · · + rkvk = 0,

where the coefficients r1, . . . , r k ∈ R are not all equal to zero.

Otherwise vectors v1, v2, . . . , v k are called linearly independent. That is, if

r₁v₁+r₂v₂+ · · · +rkvk = 0 =⇒ r₁ = · · · = rk = 0.

An infinite set S ⊂ V is linearly dependent if there are some linearly dependent vectors v₁, . . . , v k ∈ S.

Otherwise, S is linearly independent.

When 5/9 of the tank is filled in 2 minutes, then it will take 3.6 minutes to fill the entire tank.

The definition of a fraction is a fraction multiplied by another fraction, integer, or a group of variables. Given that the 5/9 tank fills in 2 minutes. The duration of this period in seconds is 60×5= 120 seconds.

So the time taken to fill a 1/9 tank is calculated as follows,

Time taken = 120/5

=24 seconds

The time taken to fill the 9/9 tank (full) is calculated by multiplying 24 seconds and 9, we get,

24×9 = 216 seconds

= 3.6 minutes.

Therefore, the required answer is 3.6 minutes.

The range of a function  is the set of all the y-values that you get when you plug all of the possible x-values into the function. It is also called a co-domain of function.

To find the range of function write down the function as y=f(x). Find all the minimum to a maximum value of y that satisfies f(x). The values obtained are the range of function. Plot the range on the graph.

For example, if you want to find the range of f(x) = 3x^2 + 6x -2. The lowest y-coordinate is at the vertex, -5, and the values for set y expand infinitely above this point. This means that the range of the function is y={-5, R}

Isabella can buy together 5 paintbrushes ( p ) and jars of paint ( p ) : j + p = 5, She can`t buy 4 items ( because 4 * $0.99 = $3.96 < $4.87 ) and she also can`t buy 6 items ( 6 * $0.95 = $5.70 > $4.87 ). So: p = 5 - j. Another equation is: 0.95 * ( 5 - j ) + 0.99 j = 4.87, 4.75 - 0.95 j + 0.99 j = 4.87; 0.04 j = 0.12; j = 0.12 : 0.04; j = 3, p = 5 - 3 = 2. We can prove it: 0.95 * 2 + 0.99 * 3 = 1.90 + 2.97 = 4.87. Answer: Isabella buys 2 paintbrushes and 3 jars of paint.

The equation that must be true for event C and D to be independent are P(C│D) = P(C) and

P(D│C ) = P(D).

Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B (i.e., P(A and B)

For two events C and D. For the two events to be independent events then;

P(C│D) = P(C∩ D)/ P(D) = P(C)

or

P(D│C) = P(D∩ C)/ P(C) = P(D)

For example if a fair die is rolled,

P(D ) = Probability of getting a 3

P(C) = Probability of getting an even number

P(C│D) = P(C∩ D)/ P(D)

P(C∩ D)= 1/3 × 1/2 = 1/6

P(C│D) = P(C∩ D)/ P(C) = 1/6 ÷ 1/3 = 1/2

The 4 types of exponents are positive, negative, zero, and rational.

When an expression or statement of specific natural numbers (0 to ∞), is represented as repeated power by multiplication of its units, then the resulting number is an Exponent.

For example, take the value 7⁵. Here the number 7 is called “base” and the number 5 (up) is called the exponent or power of that mathematical sequence. Now, to precisely calculate the value of this exponent, simply multiply the base number as many times as denoted by the power. So, for this case, it would be 7×7×7×7×7 = 16807.

The equation of a line that is perpendicular to the line y = 34x + 5 and passes through the point (0, 3) is y = -34x + 3

The slope-intercept form of the equation of a line is y = mx + c, where

The slope of a line perpendicular to another line is the negative reciprocal of the original line's slope. In this case, the original line has a slope of 34, so the slope of the line that is perpendicular to it is -1/34.

To find the y-intercept of the line, we can use the point (0,3) that the line passes through. Substituting the x and y values of this point into the equation of the line, we get 3 = -34(0) + c, which simplifies to c = 3.

The given expression is     [tex]\frac{\sqrt[4]{16xy^4}}{x^{\frac{1}{2}}y^{\frac{1}{2}}}[/tex]

In order to write the expression in the form of [tex]ax^by^c[/tex], we need to simplify it.

First, we simplify the fourth root of [tex]16xy^4[/tex] by taking the fourth root of 16, which is 2. So, the expression becomes

Any possible input value will result in exactly one output value, which is the definition of a function. "The output is a function of the input" is how we phrase it. The range is comprised of the output values, whereas the domain is made up of the input values. But not all relations are functions, and vice versa.

Formulas or graphs are typically used to depict functions.There are many different kinds of relations and functions, including empty relations, universal relations, reflexive relations, symmetric relations, transitive relations, equivalence relations, constant functions, polynomial functions, identity functions, on-to-one functions, onto functions, bijective functions, etc.

We will use the method of linear equations to get the width of the rectangle, which is 15 inches.

Here we are given that the length of the rectangle is 10 inches and the perimeter is 50 inches.

We know that the perimeter of a shape is the length of the boundary of that shape.

The formula for the perimeter of a rectangle is 2(l + b)

= 2 X (length of the rectangle + breadth of the rectangle)

Here length, l = 10 inches, the perimeter is 50 inches, and we have been to consider breadth to be w inches.

Hence we can use the formula of the perimeter and the method of a linear equation to get the width.

Hence we get

2(10 + w) = 50
