For what values (cases) of the variables the expression does not exist: a/2x−4

Answer:

-11/3 < x < 4/3

Step-by-step explanation:

-12 < 3x - 1 < 3

Add 1 to all parts.

-12 + 1 < 3x - 1 + 1 < 3 + 1

-11 < 3x < 4

Divide all parts by 3.

-11/3 < 3x/3 < 4/3

-11/3 < x < 4/3

Answer:

-58, -38, -18

Step-by-step explanation:

if for the nth term, the value is 20n-78, then for the 1st term, the value will be 20(1)-78

So we just need to use this formula for every term, starting from the 1st, until the value is no longer negative

20(1)-78 = 20-78= -58

20(2)-78 = 40-78= -38

20(3)-78 = 60-78= -18

20(4)-78 = 80-78= 2

so those are the only negative terms

The answers are -58, -38, -18.

if for the nth term, the value is 20n-78,

then for the 1st term will be 20(1)-78

the formula for every term, starting from the 1st, until the value is no longer negative

20(1)-78 = 20-78= -58

20(2)-78 = 40-78= -38

20(3)-78 = 60-78= -18

20(4)-78 = 80-78= 2

If the common difference between consecutive terms is positive, we say that the sequence is increasing. On the other hand, when the difference is negative we say that the sequence is decreasing.

The length of the hypotenuse in the given triangle is A. 15 units.

This type of question makes a right-angled triangle that can be solved by Pythagoras's theorem.

In a right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.

Given, the base of the triangle is 12 units and the height is 9 units.

∴ x² = 9² + 12².

x² = 144 + 81.

x² = 225.

x = + 15 units.

So, the length of the hypotenuse is 15 units.

Answer: A) ΔBCD ≅ ΔMKL

Step-by-step explanation:

In the given picture, it can be seen that

In Δ BCD and ΔMKL

∠B = ∠M

∠C = ∠K

∠D = ∠L

So, corresponding angles are equal.

Also,

segment BD =  segment ML

segment DC = segment KL

segment BC = segment MK

So by using SSS (Side-Side-Side) postulate of congruence, we have

ΔBCD ≅ ΔMKL

Hence, the correct option is A) ΔBCD ≅ ΔMKL.

Answer:

A) ΔBCD ≅ ΔMKL

Step-by-step explanation:

The value of the equation is A = 3/7

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first number be represented as p

The value of p = 6/7

Let the second number be represented as q

The value of q = 1/2

The value of A = p x q

Substituting the values in the equation , we get

A = ( 6/7 ) x ( 1/2 )

On simplifying the equation , we get

A = ( 6/14 )

Divide by 2 on numerator and denominator , we get

A = 3/7

Therefore , the value of A is 3/7

Hence , the equation is A = 3/7

Answer:

48°

Step-by-step explanation:

Overall, it's 360°. If you add 90° (the right triangle), x°, x°, 2x, 30°, and x° you will get 5x + 120. Subtract 120 from 360, and you will get 240. Once you get 240, you divide by 5, to solve for x.

Answer:

x = 60 Degrees

Step-by-step explanation:

Using the vertical angle theorem -->

we can conclude Ang. COB = Ang. AOD -->

Convert into an equation -->

30 + 2x = 90 + x

Combine like terms and solve

2x = 60 + x

x = 60

Answer:

5.1 = -3x - 4.2

-3x - 4.2 = 5.1

-3x = 5.1 + 4.2

-3x = 9.3

x = 9.3/-3

x = -3.1

Answer:

-3.1 =x

Step-by-step explanation:

5.1 = –3x – 4.2

Add 4.2 to each side

5.1+4.2 = –3x – 4.2+4.2

9.3 = -3x

Divide each side by -3

9.3 / -3 = -3x/-3

Step-by-step explanation:

The 22 pound bag of dog food costs $32.36. We want to find the cost per pound, or the unit rate for the 22 pound bag.

Therefore, we must divide the cost by the number of pounds.

cost/pounds

cost= $32.36

pounds= 22 lbs

$32.36/22 lbs

Divide 32.36 by 22

$1.4709090....

Round to the nearest cent, or hundredth. The 0 in the thousandths place indicates we should leave the 7 in the hundredth place.

Step-by-step explanation:

The graph for the inequality is attached with the answer.

We have a linear inequality -

y < 3x + 1

We have to plot the graph of this linear inequality.

An inequality in mathematics compares two values or expressions, showing if one is less than, greater than, or simply not equal to another value.

According to the question, we have -

y < 3x + 1

Now, in order to plot the graph for this inequality, let -

y = 3x + 1

Plot the line for the above equation. Remember to plot the graph in the form of dashed line since the inequality is strict inequality.

Consider the point (0, 0) -

Solve the inequality for the point (0, 0), we get -

0 < 3 x 0 + 1

0 < 1

Which is true.

Hence, shade the complete area on that side of line where the point

(0, 0) lies.

Answer:

X = 6

Step-by-step explanation:

Cross Multiplication

We can go about this 1 of 2 ways we can either cross multiply or divide across the numerators and denominators. Let's cross multiply. We would 4*9 = 6x. Which would simplify down to 36 = 6x. We would then divide the 6 on each sides of the equation to get 6 = X.

Dividing Across

The other way we can go about it is by seeing what 4 had to be multiplied by to get to 6. We do this by dividing 6 by for which gets us 3/2 or 1.5. Now that we know this we would then divide 9 by 3/2 or 1.5 to get the answer of 6.

Answer:

The equation has no solution

Step-by-step explanation:

The following information is missing:

Lily begins solving the equation 4(x – 1) – x = 3(x + 5) – 11.

Her work is shown below.

4(x – 1) – x = 3(x + 5) – 11

4x – 4 – x = 3x + 15 – 11

3x – 4 = 3x + 4

This means that the equation has no solution, because if we simplify her last term, we get:

-4 = 4

wich has no sense. In other words, there is no x value which satisfy:

3x – 4 = 3x + 4
