Luis does not know how old your grandfather Fernando is, but he does know the age of his father john is 20 years younger than him. Luis was 15 years old and was born when his father was 35 years old. Luis uncle is 3 years younger than his dad. Analyze the two equations bellow that represents the ages of the person describe. X+20=y Y-20-3=z what do each variable represents

Answers

Answer 1

Answer: X= John's age , Y= Fernando's age, Z = Age of Luis uncle

Step-by-step explanation:

Given: John is 20 years younger than fernando.

i.e. John' age + 20 = Fernando's age

So in the given equation "X+20=Y " , X= John's age and Y= Fernando's age.

From this , John's age: X= Y-20   (i)

Also, Luis uncle is 3 years younger than his dad( John).

Age of Luis uncle = John's age -3

=X-3

= Y-20-3         [From i]

So in the given equation Y-20-3=Z , Z = Age of Luis uncle

      constant = (y₂ - y₁) / (x₂ - x₁)

                     = (76 - 38) / (4 - 2)

                     = 38 / 2

      y = 19x

Answer:

X= 24

Answer:

x = 8.3

Step-by-step explanation:

Triangles always equal to 180 degrees when taking about angles.

The equation would be:

30+(11x+5)+(-5+7x)= 180

add like variables:

30+5-5 = 30

11x+7x = 18x

put them into an equation:

18x +30= 180

cancel out:

18x+30=180

-30 -30

18x = 150

Divide:

18x = 150

÷ 18 ÷18

x = 8.3

This is an estimate as the answer in the calculator would be very long.

The graph in the question is missing.

Answer:

y  = [tex]\frac{-1}{4}( x^3 + 2x^2 - 32x -96)[/tex]

Step-by-step explanation:

The function is cubic

It has roots as -4, -4 , 6

this means the value of x = -4, -4 , 6 which makes the entire equation zero

so we have solutions as

x+4 = 0

x+4 = 0

x- 6 = 0

on forming a cubic equation using these

(x+4)(x+4)(x-6)

the equation passes through (2,36)

put x = 2

(2+4)(2+4)(2-6) = (6)*(6)*(-4)

which exceeds 36 so we product the equation with -1/4 to get 36

Final equation

y = [tex]\frac{-1}{4} (x+4)(x+4)(x-6)[/tex]

  y  = [tex]\frac{-1}{4}( x^3 + 2x^2 - 32x -96)[/tex]

Three friends met for a book club at a coffee shop. Each friend ordered a cup of coffee and two donuts. The total of the order was $21.75. A. If a cup of coffee costs $3.25, then use the diagram to write an equation to solve for c, the cost of the donut.

Answers

the cost of a donut is $2 and the equation that represents the given scenario will be:

3d + 6c = 21.75d = 3.25

What is a Linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given, Three friends met for a book club at a coffee shop. Each friend ordered a cup of coffee and two donuts. The total of the order was $21.75.

Let " d" be the cost of a cup of coffee

and "c" be the cost of the donut

Since Each friend ordered a coffee and a donut

And there are 3 friends

Thus,

3(d + 2c) = 21.75

3d + 6c = 21.75

Also given,  a cup of coffee costs $3.25

d = 3.25

Substituting the values in equation 1

9. 75 + 6c = 21.75

6c = 12

c = 2

therefore, the cost of a donut is $2.

We can now simplify by adding 3x and 5x to get 8x.

8x + 7 = -9

We can subtract 7

8x = -16

And now, we divide by 8

x = -2
