Answer:

180

Step-by-step explanation:

Let x be the first integer.

Let y be the 2nd integer.

Given info from the question,

x = 5% x y

x = 0.05y - equation 1

x + y = 63 - equation 2

Lets now substitute equation 1 into equation 2.

0.05y + y = 63

1.05y = 63

y = 63 / 1.05

= 60

Now we substitute y into equation 1.

x = 0.05(60)

= 3

Now since we know both x and y,

we can find the product of them.

xy = 60 * 3 = 180

Answer:

I'm not too sure but:

L = (-2,-3)

M = (-9,-3)

K = (-2,-8)

J = (-9,-8)

Step-by-step explanation:

What we know:

We know that we go through the x axis then the y axis hence the saying "Along the corridor, Up the stairs".

Due to us knowing this we use where the letters (L, M, K & J) are placed on the diagram and use the "Along the corridor, Up the stairs" technique to figure out the answer.

This means that L is (-2,-3), M is (-9,-3), K is (-2,-8) & J is (-9,-8).

Yet again as I said at the top i'm not too sure but this is what I think is correct.

I hope it helps! :)

Step-by-step explanation:

the slope of a line is always the factor of x, when the line is in the form

y = ...

so,

3x + 3y = 18

3y = -3x + 18

y = -x + 6

the slope is -1 = -1/1

as the slope is the ratio of y coordinate change / x coordinate change.

a perpendicular slope switches x and y upside-down and flips the sign.

so, in our case the perpendicular slope is

1/1 = 1

[tex]p(a) = (\frac{1}{36} \times 2) \times 4 + \frac{1}{36} \times 2 = \frac{5}{18} [/tex]

The 2 (2!) is to account for permutations like ( 3 , 6 ) and ( 6 , 3 ) and the 4 are the different combinations that are composed of different numbers.Whereas combinations like ( 5 , 5 ) cannot be switched in order, so we do not multiply by 2!

(1,3) (2,2) (2,6) (4,4) (5,3) (6,6) (1,4) (2,3) (5,5) (4,6)

  d.  =SQRT(ABS(A2))

Step-by-step explanation:

A spreadsheet will not tell you the square root (or half power) of a negative number. It only performs math using real numbers.

Trying to take a square root of a negative number will result in a #NUM! error being shown in the result cell. Assuming you want the root of the magnitude of the numbers in column A, the value you want the root of is ABS(A2).

Using a dollar sign on a cell reference renders that portion of the cell reference fixed when the formula is copied. Referencing cell A$2 will mean you will get 399 copies of the square root of the contents of cell A2 in cells B2 through B400.

The formula that will give you the square root of the magnitude of the adjacent cell in column A will be

x > 0 and y < 2

We are given the inequalities;

x + 2y > 4    ----(1)

Subtract 2y from both sides in eq 1 to get;

12 - 5y < 2

Subtract 12 from both sides to get;

The equation of the line that passes through (-10,-7) and (-5,-9) is y=-2.5x-31.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The slope of the line is,

Slope, m = (-10+5)/(-7+9) = -5/2 = -2.5

Substitute any one of the points in the equation of the line,

-7 = -2.5(-10) + C

-7 = 25 + C

C = -31

Hence, the equation of the line that passes through (-10,-7) and (-5,-9) is y=-2.5x-31.

Answer:

1.39b + 2.49m = 50.73

1.29b + 2.69m = 51.63

Step-by-step explanation:

Systems of linear equations are used when we have 2 equations that both contain 2 unknown variables. Since we are trying to find the price of bread and milk, we can let b = num of bread and m = num of milk.

Betty spends $50.73 buying b loaves of bread and m gallons of milk, so the first equation would be 1.39b + 2.49m = 50.73. Betty spends $51.63 buying b loaves of bread and m gallons of milk at Store B, so the second equation is 1.29b + 2.69m = 51.63.

Answer:

i am not sure

Step-by-step explanation:

Considering the slopes of the given lines, they are parallel lines.

The slope, given by change in y divided by change in x, determines if the lines are parallel, perpendicular, or neither, as follows:

The first line, in standard form, is given by:

5y = x + 5

y = 0.2x + 1.

The slope is of m = 0.2.

For the second line, we have that:

25y = 5x - 75

y = 0.2x - 3

The slope is of m = 0.2.

Same slope, hence the lines are parallel.

Step-by-step explanation:

The solution is in the image

The sequences are classified, respectively, as:

Geometric, Arithmetic, Neither.

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

In the first sequence, we have that:

[tex]q = \frac{45}{15} = \frac{15}{5} = \frac{5}{\frac{5}{3}} = \frac{\frac{5}{3}}{\frac{5}{9}} = 3[/tex]

Hence it is a geometric sequence.

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

In the second sequence, we have that:

d = -4 - 1 = 1 - 6 = 6 - 11 = 11 - 16 = -5

Hence it is an arithmetic sequence.

[tex]\frac{4}{3} \neq \frac{3}{2}, 1 - \frac{1}{2} \neq 2 - 1[/tex]

Using the equation of slope of a line, the slope of the line that have the given coordinates is -2/3

The slope of a line represents the measure of how steep the line is, or the rate at which the line rises or falls as you move along it. It is calculated as the ratio of the vertical change (change in y-coordinates) to the horizontal change (change in x-coordinates) between any two points on the line.

If you have two points on a line, (x₁, y₁) and (x₂, y₂), the slope (m) can be calculated using the formula:

m = (y₂ - y₁) / (x₂ - x₁)

Substituting the values into the formula above;

m = 4 - (-2) / -17 - (-8)

m = 4 +  2 / -17 + 8

m = 6 / -9

m = -2/3

Answer:

33, 165, 133

Step-by-step explanation:

Check this file for the solution!

Answer:

33, 165, 133

Step-by-step explanation:

let the first number be n then

second number is 5n

third number is n + 100

sum the 3 numbers and equate to 331

n + 5n + n + 100 = 331 , that is

7n + 100 = 331 ( subtract 100 from both sides )

7n = 231 ( divide both sides by 7 )

n = 33

5n = 5 × 33 = 165

n + 100 = 33 + 100 = 133

the numbers are 33, 165, 133

Hence the value of the expression above are as listed below

f(6+4) = 25

f(6)+f(4) = 20

f(6-4) = 1

f(6)-f(4) = 6

f(6*4) = 67

f(6)*f(4) = 91

Given the expression below f(x) = 3x - 5

f(6+4) = f(10) =3(10) - 5

f(6+4) = 25

f(6) = 3(6) - 5

f(6) = 18 - 5 = 13

f(4) = 3(4) - 5

f(4) = 7

f(6)+f(4) = 13+7

f(6)+f(4) = 20

f(6-4) = f(2) =3(2) - 5

f(6-4) = 1

f(6) = 3(6) - 5

f(6) = 18 - 5 = 13

f(4) = 3(4) - 5

f(4) = 7

f(6)-f(4) = 13-7

f(6)-f(4) = 6

f(6*4) = f(24) =3(24) - 5

f(6*4) = 67

f(6) = 3(6) - 5

f(6) = 18 - 5 = 13

f(4) = 3(4) - 5

f(4) = 7

5.683

Answer:

568

Explanation:

A whole number is a number without any fractional part; in other words, it does not have any non-zero digits after the decimal point.

When you round a number to the nearest whole number, first look at the digit right after the decimal point;

• if the digit is less than 5, then the nearest whole number is the original number, but without any digit after the decimal point. [rounding down]

• if the digit is 5 or greater than 5, then the nearest whole number is the next whole number (i.e., add 1 to the original number and remove the digits after the decimal point). [rounding up]

Since the grade of the numerator and the denominator is the same, then the limit exists and is distinct from 0. The limit of the expression is 4/7.

In this problem we must apply some algebraic handling and some known limits to determine whether the limit exists or not. The limit exists if and only if the result exists.
