Answer:

Substitute your answer for the variable x. If the equation looks accurate or is correct, then the value of x is the right answer. Not sure if this makes sense

Determining whether an equation is true for all values of x or true for no values of x requires simplifying the equation, determining its domain, checking for variable restrictions, and evaluating the equation for different values of x.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Simplify the equation as much as possible using algebraic manipulations such as combining like terms, factoring, and expanding.

Evaluate the equation for a few different values of x to see if it holds true. If the equation is true for all values of x within the domain, then it will be true for all values of x. If there are any values of x within the domain that make the equation false, then it will be false for no values of x.

If the equation cannot be simplified or the domain cannot be determined, then it may require further analysis, such as graphing or using calculus techniques to determine its behavior.

Thus, determining whether an equation is true for all values of x or true for no values of x requires simplifying the equation, determining its domain, checking for variable restrictions, and evaluating the equation for different values of x.

Answer:

21°

Step-by-step explanation:

We can prove these two triangles congruent by the HL (Hypotenuse-Leg) theorem. Then, we know that m<YQR is congruent to m<PQY. We can then use their given values to form an equation.

5x+6=16x-27

Continue to solve . . .

33 = 11x

x=3

Therefore, we can plug this value of 3 into the expression for the value of m<YQR, and you will get

(16 x 3) - 27, which is equal to 21°.

Answer:

x = 6

Step-by-step explanation:

Sum of all the angles of a kite = 360

∠W + ∠Y + ∠V = 360

18x - 2 + 12x + 2  + 90 + 90 = 360          {Combine like terms}

18x + 12x  -2 + 2 + 90 +90  = 360

                  30x  + 180        = 360

                                30x    = 360 - 180

                                30x = 180

                                    x = 180/30

x = 6

Answer:

infinite solutions

Step-by-step explanation:

note the expression inside the radical is a perfect square, that is

x² - 14x + 49 = (x - 7)², then

[tex]\sqrt{x^2-14x+49}[/tex] = x - 7

[tex]\sqrt{(x-7)^2}[/tex] = x- 7, that is

x - 7 = x - 7

Since both sides are the same then any value of x will make the equation true.

The equation has infinite solutions

Answer:

141 campers voters for hotdogs

Step-by-step explanation:

h+ s = 188

h = 3s

3s + s = 188

4s = 188

s = 47

h = 141

The number of campers who voted for hot dogs is 141.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of campers = 188

The number of campers who voted for hot dogs.

= 3x

The number of campers who voted for spaghetti.

= x

Now,

3x + x = 188

4x = 188

x = 47

Now,

3 x 47

= 141

Thus,

141 campers voted for hot dogs.

Answer:

B) 2 + 4x = 5 - 3 - 3x

Step-by-step explanation:

By simplifying JUST the right side and re-arranging them

2 + 4x = 5 - 3(x + 1),

2 + 4x = 5 - 3x -3,

2 + 4x = 5 -3 - 3x

Answer: a. 0.6

b. 42 buttons

Step-by-step explanation:

a. What fraction of the buttons did not have 5 holes?

Since forty percent of the 70 buttons in the box had 5 holes, the number of buttons in the box that doesn't have 5 holes will be:

= 100% - 40%

= 60%

= 60/100

= 0.6

b. How many buttons did not have 5 holes?

This will be:

= 60% × 70

= 0.6 × 70

= 42 buttons

Answer:

∠B = 141

Step-by-step explanation:

n - > number of sides

n = 7

Sum of all interior angles = (n -2 ) * 180

                                         = 5 * 180 = 900

∠B + 148 + 90 + 142 +  130 + 129 + 120 = 900

∠B  + 759 = 900

∠B = 900 - 759 = 141

Answer:

C. Every year the number of subscribers is estimated to increase by 8% over the

number of subscribers the year before.

Step-by-step explanation:

Using the formula :

S = 20,000 (1 + 0.08)^y to estimate ;

S = number of subscribers ; y = years

The expression : (1 + 0.08)^y

0.08 = 0.08 * 100% = 8%

(1 + 0.08)^y represents a continous growth or increase in the number of subcsribers by 8% over the number of subscribers the preceeding year

Answer:

108 degrees

Step-by-step explanation:

Given the following angle measures in triangle QRS

m<Q = 1x

m<R = 3x

m<S = 6x

Note that the largest angle is the obtuse angle since they are always greater than 90 and less than 180 degrees

The sum of angle in a triangle is 180 degrees

m<Q + m<R + m<S = 180

1x + 3x + 6x = 180

10x = 180

x = 180/10

x = 18

The obtuse angle is 6x

Measure of the obtuse angle = 6x

Measure of the obtuse angle = 6(18)

Measure of the obtuse angle = 108 degrees

Hence the measure of the obtuse angle is 108 degrees
