what is 1 divided by [tex]\frac{1}{2}[/tex]?

The solution to the given system of linear equations is x = -2 and y = -8. That is, (-2, -8).

From the question, we are to determine the solution to the given system of linear equations.

The given system of linear equations is

y = 5x + 2         ---------- (1)

4x - y = 0          ---------- (2)

Substitute equation (1) into equation (2)

4x - y = 0

4x - (5x + 2) = 0

4x - 5x -2 = 0

-x -2 = 0

-2 = x

x = -2

Substitute the value of x into equation (1)

y = 5x+ 2

y = 5(-2) + 2

y = -10 + 2

y = -8

Hence, the solution is x = -2 and y = -8

The quadratic function that produces the area, f(x) = A = x², can be used to complete the table which is presented as follows;

Side length[tex]{}[/tex]   1     2    3    4    5     6

Area[tex]{}[/tex]              1     4     9   16   25  36

A quadratic function is a function which is of the general form;

f(x) = a·x² +  b·x  + c, where;

a, b, c, are numbers and the value of 'a' is not zero

The side lengths of a square are the same

The area of a square = Length of Side × Length of side

Therefore;

Area of a square = (Side length)²

The quadratic equation that gives the area, A, from a side length, x, is therefore;

The table in the question can completed using the following calculations

When the side length = 1, The area = 1² = 1

Therefore;

When the area = 4, the side length = √4 = 2

When the area = 9, the side length = √9 = 3

When the side length = 4, the area = 4² = 16

When the area = 25, the side length = √(25) = 5

When the side length = 6, the area = 6² = 36

The completed table is therefore;

The graph that indicates the transformation translating of the parent function to get, y = |x| + 3, created with MS Excel is attached

A function ix transformed when the graph of the function is translated, resized or reflected.

The formula for the transformation of a function, f(x) is y = a·f(b·(x + c)) + d

Where;

a indicates the graph of the function is dilated vertically

b  indicates a dilation horizontally

c indicates a translation horizontally

d indicates a vertical translation

The transformation applied to the parent function is the f(x) is an addition of a term, d = 3, which is a vertical translation

In a vertical translation of the form f(x) ± d

When d > 0, the graph of f(x) is moved up d units to get the graph of f(x) + d

When d < 0, the graph of f(x) is moved down d units to get f(x) - d

The graph of y = |x| + 3, obtained from the parent function, y = |x|, by a transformation of d = +3, therefore, the graph of y = |x| is moved up 3 units to get the graph of y = |x| + 3

Applying the centroid theorem, the missing measures are:

FM = 22

A.F = 66

CM = 36

ME = 18

MB = 46

DB = 69

The centroid theorem states that the distance from the centroid of the triangle to the opposite vertex is equal to one-third of the length of the segment that connects the midpoint of a side of a triangle to the opposite vertex.

Given:

AM = 44, CE = 54, and DM = 23, where M is the centroid of the triangle, thus:

FM = 1/3(FA) = 1/3(AM + FM)

Substitute

FM = 1/3(44 + FM)

3FM = 44 + FM

3FM - FM = 44

2FM = 44

FM = 44/2

FM = 22

A.F = AM + FM = 44 + 22

A.F = 66

CM = 2/3(CE)

CM = 2/3(54)

CM = 36

ME = CE - CM = 54 - 36

ME = 18

MB = 2/3(DB) = 2/3(DM + MB)

MB = 2/3(23 + MB)

3MB = 2(23 + MB)

3MB = 46 + 2MB

3MB - 2MB = 46

MB = 46

DB = DM + MB = 23 + 46

DB = 69

Answer: 4,5,6,7,8

Step-by-step explanation:

Let the first integer be A; then the five consecutive integers are A, A+1, A+2, A+3, and A+4.

If the sum of the first three equals the sum of the last two, then A + (A+1) + (A+2) = (A+3) + (A+4)

Combining, 3A + 3 = 2A + 7 … A =4

The five Integers are thus 4, 5, 6, 7, and 8

The dividend or number being divided is referred to as the antecedent, and the divisor or number that is dividing is referred to as the consequent.

A ratio compares two numbers by division. A survey of 20 respondents revealed that 13 of them preferred cake to ice cream and 7 preferred ice cream to cake.

It is given that bag of candies has several colored candies. Further, the ratio of red candies to the other colors is 2:5.

If 8 cows can graze a field in 28 days as a result, 14 cows take 12 days to graze the same field.

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

It is given that, 8 cows can graze a field in 28 days.

Suppose x is the number of days required to graze the same field.

A proportionality relationship is one that has an inverse proportion. When two quantities are inversely related when one quantity rises, the other falls. The number of hours needed to construct a wall serves as an illustration of inverse proportion. By the inverse proportional relationship,

6:x :: 14:28

x=(28×6) / 14

x=2 × 6

x=12 days

Thus, if 8 cows can graze a field in 28 days as a result, 14 cows take 12 days to graze the same field.

Answer:   700x+1700

This represents the total amount spent over the x weeks that have gone by.

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

Explanation:

x = number of weeks

700x = amount spent over those x weeks ($700 per week)

700x+1700 = total amount spent when adding on the $1700 tv.

------

An example:

Let's say x = 10 weeks have elapsed. He spends $700 a week, so 700x = 700*10 = 7000 dollars have been spent so far if we ignore the tv. Then add on the $1700 tv cost to get 7000+1700 = 8700 dollars total spent.

Then note how 700x+1700 = 700*10+1700 = 8700 matches what we got earlier.

I recommend trying out other values of x to get a better idea of what's going on.

the equation is y = (-0.03125)x + 6

where , x is the number of times the oil is dispensed and

y is the number of gallons of oil remaining in the gun ,

when the gun is full , the number of times oil dispensed will be zero .

that is x = 0  ,

Substituting x = 0 in the given equation ,

we get ,

y = (-0.03125)(0) + 6

y = 0 + 6

The point- slope of equation is y- 8 = -1/2 ( x+ 3).

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

line that passes through point (-3, 8)

and, line is y= -1/2 x + 6

From above equation the slope of line is -1/2

Now, the point slope form of line

y- [tex]y_1[/tex] = m (x- [tex]x_1[/tex])

y- 8 = -1/2 ( x - (-3))

y- 8 = -1/2 ( x+ 3)
