Solve r-x+2y =1 for y

Answer:

15. Hope it helps!

Step-by-step explanation:

Explanation:

We cannot have zero in the denominator. If x = 0, then the denominator 6x becomes 6x = 6*0 = 0. So we must exclude this from the domain to avoid a division by zero error.

One could argue that the 'x's cancel out when we divide. Yes that's true and [tex]\frac{5x}{6x} = \frac{5}{6}[/tex], but as far as the calculator is concerned, it will not try to simplify the expression (unless it's a specific type of calculator). Instead, the calculator would likely follow the order of operations PEMDAS to try to compute directly. The calculator would hit the stumbling block of dividing by zero and produce "undefined" or "not a number".

Answer:

Step-by-step explanation:

First, you have to find the degress for m<A.

m<A+ 90+37=180

m<A+ 127=180

then you subtract 127 from both sides.

So, m<A= 53 degress, We already know that m<B is 90,

So let's solve for m<C.

m<C + 53+ 90= 180

m<C+ 143=180

m<C= 37 degress.

Since the triangles are both the same and has the same length and are congruent polygons

m<X=53 degress, m<Y= 90 degress, and m<Z= 37 degress

Answer:

Step-by-step explanation:

Divide 6 by 4

The answer is 1 R 5, because ↓

4 goes into 6 one time.

However, the 5 comes from a different level of diverse multiplication. We will skip past that concept for now.

If there is a number outside parentheses without a symbol, that usually means multiply.

[tex]1.5 * 2 = 3[/tex]

Therefore, the answer is 3.

Step-by-step explanation:

given f(x) = 2/x and g(x) = 2/x

f(g(x)) = 2/(g(x)) = 2/2/x = x/2 × 2 = x

g(f(x)) = 2/(f(x)) = 2/2/x = x/2 × 2 = x

therefore they are inverses

since f(g(x)) = g(f(x)) = x.

Answer: 2.7

Step-by-step explanation:

(1)(1/10)+(2)(3/10)+(3)(4/10)+(4)(2/10)=2.7

Answer and Step-by-step explanation:

To solve for x, we need to look at 2 deciding factors that allows us to be able to find x.

We are given 2 parallel lines, denoted by the arrow pointing right on the end of both of them, and a transversal line that cuts through the two lines. Because the lines are parallel, the angles that are formed by the transversal like will be equal or correspondent to each other in a few ways.

For the angles we are given, the angles are on the same side of the transversal line, and on the top of their respective parallel lines. Because of this, the angles are equal to each other.

To solve, set the two angles equal to each other.

4x + 20 = 2x + 60

Subtract the 2x from both sides of the equation.

2x + 20 = 60

Subtract the 20 from both sides of the equation.

2x = 40

Divide both sides by 2.

x = 20

x is equal to 20.

Given -

two parallel lines with a transversal.

To find -

to find the value for x.

Concept applied -

Here in the figure, these two angles let's say 1 = 4x + 20° and 2 = 2x + 60° are corresponding angles. And we know that corresponding angles are equal. As all these angles that have the same position in leu the parallel lines and the transversal are corresponding pairs. Therefore, 1 = 2

Solution -

➙ 4x + 20° = 2x + 60°

➙ 4x - 2x = 60° - 20°

➙ 2x = 40°

➙ x = 40°/2

➙ x = 20°

Henceforth, the value of x = 20°.

The prediction of a roll of 12 is the expected value of rolling a 12

Jenny can predict 15 as the number of times she will roll a 12

The dice is a 12-sided dice.

This means that the dice has 12 sides.

So, the probability of obtaining a 12 is:

P(12) = 1/12

In a roll of 180 times, the number of times a 12 is expected to show is:

E(x) = np

This gives

E(x) = 180 * 1/12

Evaluate the product

E(x) = 15

Hence, Jenny can predict 15 as the number of times she will roll a 12

Answer: the answer is B,  each term is multiplied by the same number to arrive at the next term

Step-by-step explanation:

Answer:

It's B. Each term is multiplied by the same number to arrive at the next term. as well as D. There is a common ratio between terms.

Step-by-step explanation:

In a geometric sequence, each term is equal to the previous term times a constant, non-zero multiplier called the common factor. Geometric sequences can have a fixed number of terms, or they can be infinite. They must be a progression of terms as well.

Line 2 presents the error for the solution presented because the square of numbers: 14 and 8 was calculated incorrectly.

This law can be applied when two sides of the triangle and the angle formed for these sides are known. Therefore, from the law of cosines, it is possible to write the relation between sides and their respective cosines. See below:

                           [tex]c^2=a^2+b^2-2*a*b*cos(C)[/tex]

For solving this question, you should apply the Law Cosines and after that compare your solution with this exercise. From the comparison, you should identify the mistake for the solution presented in this problem.

                 [tex]c^2=a^2+b^2-2*a*b*cos(C)\\ \\ c^2=14^2+8^2-2*14*8*cos(80)\\ \\ c^2=196+64-224*0.1736\\ \\ c^2=196+64-38.8864\\ \\ c^2=221.1136\\ \\ c=\sqrt{221.1136}=14.9[/tex]
