Answer:  2

Step-by-step explanation:

                             Current Age              Age in future (x years)

Brother 1:                   15                                 x + 15

Brother 2:                  22                                x + 22

The product of their ages in the future is 408:

            (x + 15)(x + 22) = 408

            x² + 37x + 330 = 408          Expanded

            x² + 37x - 78 = 0                  Subtracted 408 from both sides

            (x + 39)(x - 2) = 0                 Factored

   x + 39 = 0     x - 2 = 0                  Applied Zero Product Property

         x = -39         x = 2                   Solved for x

                ↓

          Disregard since "future" years cannot be negative

Answers

Answer:

D

Step-by-step explanation:

We have the set:

[tex]\{(2, -3), (-1,0), (0, 4), (-1, 5), (4, -2)\}[/tex]

Remember that the domain for a set of values is simply the input values.

In other words, our domain will be all of our x-coordinates.

We can see that our x-coordinates are: 2, -1, 0, -1, and 4.

So, our domain is:

[tex]\{2, -1, 0, 4\}[/tex]

Note that we only write need to write the -1 once.

So, our answer is D.

And we're done!

Frank believes his bedroom wall measures 12 feet long.
He has a ruler that is 1? feet long.
He uses this ruler to measure his bedroom wall.
Which equation can be used to solve for T,
the number of times he will have to use the ruler to check the length of his bedroom wall?

A. 1? = 12T
B. 1? T = 12
C. 1? + T = 12
D. T – 1? = 12

Answers

Answer:

A

Step-by-step explanation:

Answer:

B. 1? T = 12

Step-by-step explanation:

Since the bedroom measures 12 feet long, the answer or the product should be 12 (12 only)

He uses “1?” to measure the bedroom, and we need to know HOW MUCH TIMES he uses it.

So, 1? T will be the equation since we need to know how much times he uses the ruler.

What is Coordinates?

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

There are an ordered pair and coordinates.

Now,

The difference between an ordered pair and coordinates will be;

''Coordinates are used in geometry, and when there are two coordinates, they are ordered pairs when both component are of the same type.''

And, An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of

(a, b) and a coordinate system is a two-dimensional number line.

Thus, The difference between an ordered pair and coordinates will be;

A function is defined as a relation between a set of inputs having one output each.

The range of the function is -3.

What is a function?

A function is defined as a relation between a set of inputs having one output each.

f(x) = x + 2

At x = 2,

f(2) = 2 + 2 = 4

Domain = 2

Range = 4

We have,

f(t) = -2t² + 1

We need to find for t = -3.

f (-3) = -2 ( -3 )² + 1

[ -3 x -3 = 9 ]

f (-3) = -2 x 9 + 1 = -18 + 1 = -17

Thus the value of the function f(t) = -2t² + 1 at t = -3 is -17.

Determine the solution.
2x+y=4
4x-3y=7

Answers

Answer:

The answer is: (x , y) = (19/10 , 1/5)

Step-by-step explanation:

Solve the equation for y-

y = 4 - 2x

4x - 3y = 7

Substitute the given value of y into the equation-

4 x - 3 ( 4 - 2x ) = 7

Solve the equation for x-

x = 19/10

Substitute the given value of x into the equation y = 4 - 2x-

y= 4 - 2 * 19/10

Solve the equation for y-

y = 1/5

The possible solution of the system is the ordered pair ( x , y )-

( x , y ) = ( 19/10 , 1/5)

Check if the given ordered pair is the solution of the system of equations-

{2 * 19/10 + 1/5 =4

4 * 19/10 - 3*1/5 =7}

Simplify the equalities-

4 = 4

7 = 7

Since all equalities are proven true the ordered pair is the solution of the system-

( x , y) = (19/10, 1/5)

FINALLY haha the solution is: ( x , y ) = (19/10 , 1/5)

Match each circular flower bed on the left to its circumference and its area on the right. Some answer options on the right will not be used.

Answers

Answer:

Bed A --- Third Option

Bed B --- Fifth Option

Step-by-step explanation:

Flower Bed A)

The formula for circumference is:

[tex]C=2\pi r[/tex]

The diameter of A is 10 feet. So, its radius is 5 feet.

Substitute 5 for r. So, the circumference of Bed A is:

[tex]C=2\pi (5)=10\pi\text{ feet}[/tex]

The formula for the area of a circle is:

[tex]A=\pi r^2[/tex]

Substitute 5 for r:

[tex]A=\pi (5)^2[/tex]

Square and simplify:

[tex]A=25\pi \text{ square feet}[/tex]

So, the circumference of Bed A is 10π feet and its area is 25π square feet.

Therefore, match Bed A to the third option.

Flower Bed B)

The radius of Bed B is 6 feet. Again, we can use the circumference and area formulas. Substitute 6 for r for circumference:

[tex]C=2\pi (6)[/tex]

Multiply:

[tex]C=12\pi\text{ feet}[/tex]

Substitute 6 for r for the area formula:

[tex]A=\pi(6)^2[/tex]

Square and simplify:

[tex]A=36\pi\text{ square feet}[/tex]

So, Bed B has a 12π feet circumference and a 36π square feet area.

Therefore, match Bed B to the fifth option.

And we're done!

Step-by-step explanation:

We know a straight line is 180 degrees and that m∠7 is 100 degrees.

m∠9, m∠5 and m∠11 are 100 degrees

To find m∠6, m∠8, and m∠2 we subtract 100 from 180 and get 80 degrees.

If f(x) = 8x + 1 and the graph of g is the graph f translated 2 units to right, which equation represents g?
A. g(x) = (6x + 1) + 2
B. g(x) = (6x + 1) - 2
C. g(x) = 8(x + 2) + 1
D. g(x) = 8(x - 2) + 1
Can someone please help?

Answers

The answer is D. g(x)= 8(x-2)+1

The equation of the graph after 2 units of the right translation will be g(x) = 8(x - 2) + 1. The correct option is d.

What is a function?

The expression that established the relationship between the dependent variable and independent variable is referred to as a function. In the function as the value of the independent variable varies the value of the dependent variable also varies.

Given function f(x) = 8x + 1 is translated by 2 units to the right on the graph.

The function will be changed as below,

f(x) = 8x + 1

After translation, the value of x will become x - 2.

f(x) = 8(x-2) + 1

Therefore, the equation of the graph after 2 units of the right translation will be g(x) = 8(x - 2) + 1. The correct option is d.

what is y when the equation is x^2 - 3xy -4y^2 =0

Answers

Answer:

y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))

Step-by-step explanation:

Solve for y:

-4 y^2 - 3 x y + x^2 = 0

Hint: | Multiply both sides by a term to make the coefficient of y^2 positive.

Multiply both sides by -1:

4 y^2 + 3 x y - x^2 = 0

Hint: | Using the quadratic formula, solve for y.

y = (-3 x ± 5 sqrt(x^2))/8:

Answer: y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))
