Answer:

Ramu's sister's Age= 28

ramus age=×

28=5×+3

5×=28-3

=25

×=25/5

×=5

so the age of Ramu is 5 years old.

Answer:

25 because 5×5= 25 and 25+3=28 so ramu's age is 25

Answer:

y = 3x + 19

Step-by-step explanation:

Here m is the slope and b is the y-intercept.

     y = 3x + 4

m = 3

Parallel lines have same slope.

   m = 3

y = 3x + b

Substitute (-5,4) in the above equation.

        4 = 3*(-5) + b

        4 = -15 + b

  4 + 15 = b

           b = 19

Equation of the line: y = 3x + 19

Answer: y = 3x +19

Step-by-step explanation:

-Parallel lines have the same gradient

y = 3x + c

rearrange to give c= y - 3x

substitute x = -5 and y = 4

c = 3 - (3x-5)

c= 19

so the equation is y = 3x + 19

The two numbers are 10 and 6.

Now, let's take the larger number to be x and the smaller number to be y.

According to the question,

We have the following details:

The difference between two numbers = 4

So, we have the following expression:

(x-y) = 4 .... (1)

The sum of the smaller number and three times the larger number = 36

So, we have the following expression:

(3x+y) = 36 ....(2)

Now, we will use the elimination method to solve these equations. So, we will add equation 1 and 2.

(Please note that the left hand side is added to the left hand side and the right hand side numbers are added to the right hand side numbers.)

(x-y+3x+y) = (4+36)

4x = 40

x = 40/4 (4 is in multiplication on the left hand side. So, it is in the division on the right hand side.)

x = 10

Now, putting the value of x in equation 1,

(x-y) = 4 .... (1)

(10-y) = 4

-y = 4-10

-y = -6

y = 6

Hence, the larger number is 10 and the smaller number is 6.

Answer:

[tex]\boxed{a} \quad \boxed{|b - c|} \quad \boxed{|a - b|} \quad \boxed{|a - c|}[/tex]

Step-by-step explanation:

The bars either side of an expression or a value are the absolute value symbol.  "Absolute value" means how far a number is from zero.   Therefore, the absolute value of a number is its positive numerical value.  

The values of a, b and c are negative. All expressions except "a" are absolute values, and are therefore positive numerical values. Therefore, "a" is the least expression.

The simplest way to calculate each expression's numerical value is by assigning approximate numbers to each value, then carrying out each calculation.

From inspection of the graph:

[tex]\begin{aligned} \implies |a - b| & \approx |-3.8 - (-1.3)|\\ & = |-2.5| \\ &= 2.5\end{aligned}[/tex]

[tex]\begin{aligned} \implies |b - c| &\approx |-1.3 - (-0.7)| \\ &= |-0.6| \\ &= 0.6\end{aligned}[/tex]

[tex]\implies a \approx -3.8[/tex]

[tex]\begin{aligned} \implies |a - c| &\approx |-3.8 - (-0.7)| \\ &= |-3.1| \\ &= 3.1\end{aligned}[/tex]

Therefore:  -3.8 < 0.6 < 2.5 < 3.1

Hence, the expressions from least to greatest are:

[tex]\boxed{a} \quad \boxed{|b - c|} \quad \boxed{|a - b|} \quad \boxed{|a - c|}[/tex]

The translation of y = |x| left 9 units and up 11 units is y = |x+9|+11 .

The process of translating an existing graph or equation into a new graph is known as graph translation.

We know that for translation we have to change the x-coordinate and the y-coordinate by the amount that is stated in the translation.

Therefore from the graph we can see that the graph of y =|x| is represented by the blue line and the graph of  translation y = |x+9|+11 is represented by the red line.

r(x) = 2

Since x will always be 2, it will always be a straight line.

Problem 14:

(I'm assuming the square is on the x)

g(x) = x^2-3

First, start on the y-intercept, and go down 3 as the starting value is -3. You can then substitute a number to find the next point.

For example, if you want to find if x = 1, what y will be:

1^2-3

1-3

-2

You can then do this for the rest of the points to the point.

Combine X. which is 2x, -5x, x.

we combine -2x and -5x and gives me -3x.

2x -10 -5x -1 +x

now i combine the last x, which is -3x and x and gives us -2x.

The maximum that the company can expect for returned items is C. $5972.65

From the information, the average daily profit of an electronics store is $31,435 and the company estimates that 15% is lost each day to returns, with a margin of error of ±4%.

In a random survey sample, a margin of error is a statistical measurement that takes into account the discrepancy between actual and anticipated findings. Simply said, you may determine the degree of unpredictability in data and research results using the margin of error.

The maximum the company can expect for returned items will be:

= (15% + 4%) × Profit

= 19% × $31,435

The Compound Interest of Principle 2000 will become 2420 within 2 years when the rate of interest is 21%

[tex]13x+45+19x+3=180 \\ \\ 32x+48=180 \\ \\ 32x=132 \\ \\ x=33/8[/tex]

Answer:

x = 7

Step-by-step explanation:

Vertical Angle Theorem

When two straight lines intersect, they form two pairs of angles.  The vertically opposite (non-adjacent) angles are congruent.

Angles on a Straight Line Theorem

The sum of angles formed on a straight line is equal to 180°.

The error made is confusing the Vertical Angle Theorem with the Angles on a Straight Line Theorem.  To find x, we should either:

Applying the Vertical Angle Theorem:

[tex]\boxed{\begin{aligned} (13x+45)^{\circ} &=(19x+3)^{\circ} \\13x+45&=19x+3\\13x+42&=19x\\42&=6x\\x&=7\end{aligned}}[/tex]

Applying the Angles on a Straight Line Theorem:

[tex]\boxed{\begin{aligned}(6x+2)^{\circ}+(19x+3)^{\circ}&=180^{\circ}\\6x+2+19x+3&=180\\25x+5&=180\\25x&=175\\x&=7\end{aligned}}[/tex]

Answer:

Below in bold.

Step-by-step explanation:

The relation between the height of the ladder and distance from the ground is given by Pythagoras Theorem:

h^2 = 13^2 - L^2

h = (169 - L^2)^1/2

Finding the derivative:

dh/dL = 1/2(169 - L^2)^-1/2 * -2L

         = -L / (169 -L^2)^1/2

dL/dt = 6

So, dh/dt = dh/dL * dL/dt

               = -6 * L/ (169 - L^2)^1/2

               = -6 * 12 / (169 - 12^2)^1/2

                = -72/5 ft /second

                 = -14.4 ft/second.

It's negative because the distance from the ground is decreasing.

The equation of the line in slope intercept form with slope 1/3 and passes through ( - 6, 0) is y = 1/3x + 2.

In mathematics, the slope or gradient of a line is a number that indicates the line's steepness as well as its X and Y directions. The letter "m" stands for slope. The ratio of the "vertical change" to the "horizontal change" between any two separate points on a line is used to compute the slope.

The equation of the line in point-slope form is expressed as:

y - y₁ = m( x - x₁ )

where m is the slope.

So, m = 1/3

( x₁, y₁ ) is the point on the line = ( - 6, 0)

Substituting the values,

y - 0 = 1/3( x + 6 )

y = 1/3( x + 6 )

y = 1/3x + 6/3

y = 1/3x + 2

Hence, the equation in slope-intercept form of the line is y = 1/3x  + 2.

The inverse of the given function, y = 16x² + 1 is: B. y = ±√(x - 1)/16

In Mathematics, an inverse function can be defined as a type of function that is obtained by reversing (undoing) the operation of a given function (f(x)).

Generally speaking, a given function (f(x)) and its inverse function has the following property f⁻¹(f(x)) = x.

In order to determine the inverse of the given function, we would interchange input value (x) and the output value (y) as follows:

y = 16x² + 1

x = 16y² + 1

Subtracting 1 from both sides, we have:

16y² + 1 - 1 = x - 1

16y² = x - 1

Dividing both sides by 16, we have:

y² = (x - 1)/16

Taking the square root of both sides, we have:

y = ±√(x - 1)/16
