Solve each pair of simultaneous equations by substitution method
WARRIOR [948]

Answer:

x = 1       y = -4

Step-by-step explanation:

- Plug the value of y into the other equation.

x + 3y = -11

x + 3(-4x) = -11

x - 12x = -11

-11x = -11

x = 1

- Now substitute the value of x into any equation.

y = -4x

y = -4(1)

y = -4

A survey of 100 high school students provided this
HACTEHA [7]

Answer:

35/100

Step-by-step explanation:

You have to find how many juniors there are, so if you add 13, 20, and 2 you get 35. For the denominator you have to find the total number of students, so just add all of the numbers together to get 100. So there is a 35/100 chance that a randomly selected student is a junior.

It takes three identical water pumps 8 hours to fill a pool, What is the constant of variation?
BaLLatris [955]

Answer:

Constant of variation is 24.

Step-by-step explanation:

Inverse variation states that a relationship between two variables in which the product is remain constant.

If one variable increases then, the other one decreases in proportion so that the product is unchanged,

if y is inversely proportional to x i.e y \propto\frac{1}{x} or

y =\frac{k}{x} ;where k is the constant of variation.

It is given that 3 identical water pumps takes 8 hours to fill a pool,

since, it will take less time with  more pumps, so it is an inverse variation.

By definition of inverse variation;

time = \frac{k}{pump}

Substitute the values to solve for k;

8 = \frac{k}{3}

Multiply by 3 to both sides we get;

8 \times 3 = \frac{k}{3} \times 3

Simplify:

k = 24

Therefore, the constant of variation is, 24

Explain why angle Y is congruent to angle B
DerKrebs [107]

<u><em>Note: It seems you may have unintentionally missed to add the complete question statement, but I will make sure to make you understand the concept of angle congruence anyways using which you may be able to clear all your queries regarding the concept.</em></u>

Answer:

When we say the angles Y and B are Congruent. It means these congruent angles have the same angle measured in degrees. (or in radians as both are units of measure for angles).

The figure a is also attached below to visualize the concept.

Step-by-step explanation:

When we say the angles Y and B are Congruent. It means these congruent angles have the same angle measured in degrees. (or in radians as both are units of measure for angles).

Here are some additional things to observe:

  • Angles are congruent as long as the angles are the same
  • they don't have to point in the same direction
  • they don't have to be made with lines of the same length.

For instance, below is the example. Where,

  • Angle Y is 42°
  • Angle B is 42°

As the measure of these angles is same. It means the angles Y and B are Congruent. The figure a is also attached below to visualize the concept.
