Answer:

Yes it is a function.

use you can try out the Vertical Line test which states that if your line intersects repeatedly it is not a function.

Every x-value is paired with a y-value. If the x-value is being paired with more than one y-value it does not pass the test.

All these values you had listed pass the vertical line test.

Hope this helps!

Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.
pogonyaev

Answer:

The small balloon bouquet uses  7 balloons and the large one uses

18 balloons.

Step-by-step explanation:

Let's say that small balloon bouquets are S and large balloon bouquets are L. For the graduation party the employee assembled 6 small bouquets and 6 large bouquets, the total number of balloon used is 150. To put the sentence into an equation will be:

6S + 6L= 150

S+L= 25   ----> 1st equation

For Father's Day, the employee uses 6 small bouquet and 1 large bouquet, the total number of balloons used is 60. The equation will be:

6S + 1L= 60

1L= 60- 6S   ----> 2nd equation

We can solve the number of small balloon bouquet by substitute the 2nd equation into 1st. The calculation will be:

S+L = 25

S+ (60-6S)= 25

-5S= 25-60

-5S= -35

S= -35/-5

S=7

Then we can find L by substitute S value to 1st or 2nd equation.

S+L=25

7+L=25

L=18

A professor gives two types of quizzes, objective and recall. He is planning to give at least 15
nadya68 [22]

Answer:

x₁ = 20     x₂ = 0

z (min) = 20

Step-by-step explanation:

According to the problem statement:

Let´s call

Objective quiz =  x₁               Recall quiz =  x₂

First constraint

Quantity of quizzes at least 15

x₁  +  x₂  ≥ 15

Second constraint:

Preparation time   at least 300 minutes, then

15*x₁  +  30*x₂  ≥   300

Third constraint

Average score  at least  85 points

7*x₁  +  5*x₂   ≥  85

General constraint x₁ ≥ 0   x₂ ≥ 0

Objective function z is:

z = 1* x₁ + 1,5*x₂     to minimize

The model:

z = x₁  + 1,5x₂      to minimize

Subject to

x₁  +  x₂  ≥ 15

15*x₁  +  30*x₂  ≥   300

7*x₁  +  5*x₂   ≥  85

Using Atozmax (online solver) we find

x₁ = 20     x₂ = 0

z (min) = 20

If x=5 and y= -4, evaluate this expression: (-2x +10) - (-6x + 5y + 12) + (x +8y - 16)
saul85 [17]

Answer:

The value of the expression is - 5.

Step-by-step explanation:

(-2x +10) - (-6x + 5y + 12) + (x +8y - 16)=

-2x+10+6x-5y-12+x+8y-16=

(-2x+6x+x)+(-5y+8y)+(10-12-16)=

5x+3y-18

if x=5 and y=-4 then

5*5+3*(-4)-18=25-12-18=25-30=-5
