Let the sons age = x

The dads age would be 3x ( 3 times the sons age)

X + 3x = 48

Simplify:

4x = 48

Divide both sides by 4

X = 12

The sons age is 12

Answer: x = -11

Step-by-step explanation:

Expand the expression (distributive property): 3 - 9x = -8x + 14

// subtract 14 from both sides = -11

// add 9x on both sides = x

Simplify: x = -11

Answer:

[tex]x=-11[/tex]

Step-by-step explanation:

1) Rearrange Terms

[tex]3(-3x+1)=2(-4x+7)[/tex]

2) Distribute

[tex]-9x+3=2(-4x+7)[/tex]

3) Distribute

[tex]-9x+3=-8x+14[/tex]

4) Subtract 3 from both sides of the equation

[tex]-9x+3-3=-8x+14-3[/tex]

5) Simplify

A. Subtract the numbers

[tex]-9x=-8x+14-3[/tex]

B. Subtract the numbers

[tex]-9x=-8x+11[/tex]

6) Add 8x to both sides of the equation

[tex]-9x+8x=-8x+11+8x[/tex]

7) Simplify

A. Combine like terms

[tex]-x=-8x+11+8x[/tex]

B. Combine like terms

[tex]-x=11[/tex]

8) Divide both sides of the equation by the same term

[tex]\frac{-x}{-1} =\frac{11}{-1}[/tex]

9) Simplify

A. Cancel terms that are in both the numerator and denominator

[tex]x=\frac{11}{-1}[/tex]

B. Divide the numbers

[tex]x=-11[/tex]

A A equation that’s perpindicular to y = 4x - 1 and passes through the point (2, -9) is…

Answer: y = -3/4x - 15/2

Explanation: Opposite reciprocal slopes and plug in -9 with y and 2 with x then solve for b

-9 = -1.5 + x

x = -15/2

Answer:

Step-by-step explanation:

6) y = 2x² +  6x - 80

1) y = 2*x² + 2*3x - 2*40

  y = 2 [ x² + 3x - 40]

2) Sum = 3

Product = -40

Factors = (-5) ; 8   {-5 +8 = 3  ; (-5)*8 = -40}

y = 2 [ x² + 8x - 5x - 40]

      = 2 [ x(x + 8) -  5(x + 8) ]

      = 2 [ (x +8) (x - 5)]

y = 2(x +8)(x -5)

b) y = 0

2(x + 8)(X - 5) = 0

x + 8 = 0 ;  x - 5 = 0

x = -8 ;             x = 5

(-8) ; 5  are the zeros.

0.75

Explanation:

Every 1/4 is 25. If you want to calculate them, then you're going to need 1/4 to find 25. In some other cases, 25, can also be written as another decimal. Such as, 4/100.

100/4 is 25. For example:

Woah! You have 3/4 of a dollar. You're really saving up money fast!

This example means that the person has 75 cents.

For an ounce, that would mean 0.04 pounds.

The probability that Jorge draw a diamond from the deck of cards and roll a number greater than two is 2/39

Probability is the like likelihood or chance that an event will occur.

Probability = Expected outcome/Total  outcome

If Jorge has a standard deck of 52 cards, the total outcome is 6

If Jorge draw a diamond card, the probability that he will draw a diamond card is 4/52 = 1/13

For a six-sided cube, the total outcome is 6. If he rolls a number greater than two, the expected outcome will be 4

The probability that he rolls a number greater than 2 is 4/6 = 2/3

The probability that Jorge draw a diamond from the deck of cards and roll a number greater than two is 1/13 * 2/3 = 2/39

Answer:

there is one line of symmetry if you look closely at the shape

Answer:

Both of them are correct.

Step-by-step explanation:

Both of them are correct.  

EQ. 1)  y = -2x + 3

EQ. 2)  6x + 3y = 9

Transform EQ. 2 into its slope-intercept form, y = mx + b:

6x + 3y = 9

6x - 6x + 3y = -6x + 9

3y = -6x + 9

3y/3 = (-6x + 9)/3

y = -2x + 3  (As you can see, Equation 2 is equivalent to Equation 1's).

Given that Equations 1 and 2 are equivalent, their lines will coincide on top of each other (as if they're the same line) once graphed.  

Therefore, the systems of linear equations will have infinitely many solutions.

Let's see why Charles and Destiny are both correct with their claims.  

If you plug in Charles' coordinates (3, -3) in both equations,

EQ. 1)  y = -2x + 3

-3 = -2(3) + 3

-3 = -6 + 3

-3 = -3  (True statement)

EQ. 2)  6x + 3y = 9

6(3) + 3(-3) = 9

18 - 9 = 9

9 = 9 (True statement)

Do the same thing for Destiny's coordinates: (-1, 5)

EQ. 1)  y = -2x + 3

5 = -2(-1) + 3

5 = 2 + 3

5 = 5 (True statement)

EQ. 2)  6x + 3y = 9

6(-1) + 3(5) = 9

-6 + 15 = 9

9 = 9  (True statement)

With these calculations, it shows that both of their coordinates are solutions to the given systems of linear equations.

Answer:

<ABC = 70 degrees

<AMC = 60 degrees

< AMB = 60 degrees

Step-by-step explanation:

<ABC = 180-110 = 70 degrees

<AMC = 2x + 60 = 180

2x = 180 - 60

x = 120/2

x = 60

<AMB = 180/3 = 60
