For the function f(x) = 2x + 9, find the value of x when f(x) = 15.

Answer:

(4x^5)^2 you just need to square 4x^5

Answer:

Step-by-step explanation:

one side = 4x^5

four sides of the square= (4x^5)^2

= (4x^5)* (4x^5)

=16x^10

A ratio will just be trying to find whole number versions of these decimals and then compare them side by side (always divide the larger number by the smaller number).

Therefore:

[tex]\frac{0.0000275}{0.000005}=5.5=\frac{5.5}{1}[/tex]

However, this isn't a proper ratio. Generally, ratios are whole numbers. Since it's 5.5, we can easily make this a whole number by multiplying it by 2. Keep in mind though, what we do to one number we do to the other! So:

[tex]\frac{2}{2}(\frac{5.5}{1})=\frac{2*5.5}{2*1}=\frac{11}{2}[/tex], technically this is a better format since it's whole numbers, but it gives you the ratio (11:2) which is a bit tougher to interpret than (5.5:1)

Therefore, the ratio we'll use is 5.5:1 for simplicity's sake:

From this ratio, we can see that the red tablet is 5.5x the size of the white tablet.

Hope this helps! :)

Answer:

-20

Step-by-step explanation:

-20

Answer:

divided: 6x+4+(5)/(x+5)

the remainder: 5

I like to use long division to work these problems:

                        6x   +  4          

        (x+5)  ║ (6x² + 34x + 25)

                    - (6x  + 30x)   ↓

                                   4x + 25

                               - (4 x + 20)  

                                             5

                     (6x^2 + 34x + 25)/(x+5)  = 6x + 4 with a remainder of 5

Step-by-step explanation:

Answer:

False.

Step-by-step explanation:

No f(x) is not a function because it is  a one-to-many relation

Note that  5 maps to 1 and 3 so this is not a function.

The point of intersection is the point where two or more functions meet.

The graphs of the hyperbola and ellipse have 0 point of intersection

The given parameters are:

[tex]\mathbf{3x^2 - 4y^2 + 4x - 8y + 4 = 0}[/tex]

[tex]\mathbf{3x^2 + y^2 + 4x - 3y + 4 = 0}[/tex]

To determine the points of intersection, we simply equate both equations.

So, we have:

[tex]\mathbf{3x^2 + y^2 + 4x - 3y + 4 = 3x^2 - 4y^2 + 4x - 8y + 4 }[/tex]

Cancel out the common terms

[tex]\mathbf{y^2 - 3y = - 4y^2 - 8y }[/tex]

Collect like terms

[tex]\mathbf{y^2 +4y^2= 3y - 8y }[/tex]

[tex]\mathbf{5y^2= - 5y }[/tex]

Divide through by 5

[tex]\mathbf{y^2= - y}[/tex]

Divide through by y

[tex]\mathbf{y= -1}[/tex]

The system of equation does not give room to calculate the x-coordinate at the x-axis.

Hence, the graphs of the hyperbola and ellipse have 0 point of intersection

Explanation: Took the test

Answer:

infinite number of solutions

Step-by-step explanation:

4(z - 5) + 2 = 4z - 18 ← distribute and simplify left side

4z - 20 + 2 = 4z - 18

4z - 18 = 4z - 18 , which reduces to

0 = 0 ← a true statement

This indicates the equation has an infinite number of solutions

Answer:

1) 350

2) 195.83

Step-by-step explanation:

Tuition fee = $12, 000 per year.

30% of it's being paid off by the scholarship, so she'll have to pay:

[tex] = 12000 - ( \frac{30}{100} \times 12000) [/tex]

[tex] = 12000 - 3600[/tex]

[tex] = 8400[/tex]

She'll have to pay $ 8400 by herself, her savings.

If she's saving $ 8400 for two years, she's actually saving $ 8400 for 24 months!

for one month, it'll be

= 8400/ 24

= $ 350 per month

one year fee = $ 10, 700

uncle pays half of it, I.e., 10700/ 2

= $ 5, 350

he gets a grant for $ 3,000

so, the part of the fee he ain't paying

= 5,350 + 3000

= $ 8,350

So, he'll have to save:

= 10,700 - 8,350

= $ 2,350

that is per year,

for per month = 2350/ 12

= $ 195.83

For me, a percent is easier to think about.  Knowing I scored 80% make sense.  80%, like 80¢ out of a dollar, makes sense and I can relate to it.

If you tell me I scored 52/65, I can't relate to that as easily, even though that's still 80%.

Step-by-step explanation:

Yes. because In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers

Answer:

yes

Step-by-step explanation:

Irrational numbers are numbers that simply are not rational, and cannot be written as a fraction, though they cna be written as a decimal. Irrational numbers msot of the time have a lnog row of non-repeating numbers after the decimal. So, yes.

Answer:

w=-13/4

w=2

Step-by-step explanation:

|8w+5|=21

Step by step solution :

STEP

1

:

Rearrange this Absolute Value Equation

Absolute value equalitiy entered

     |8w+5| = 21

STEP

2

:

Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |8w+5|

For the Negative case we'll use -(8w+5)

For the Positive case we'll use (8w+5)

STEP

3

:

Solve the Negative Case

     -(8w+5) = 21

    Multiply

     -8w-5 = 21

    Rearrange and Add up

     -8w = 26

    Divide both sides by 8

     -w = (13/4)

    Multiply both sides by (-1)

     w = -(13/4)

    Which is the solution for the Negative Case

STEP

4

:

Solve the Positive Case

     (8w+5) = 21

    Rearrange and Add up

     8w = 16

    Divide both sides by 8

     w = 2

    Which is the solution for the Positive Case

STEP

5

:

Wrap up the solution

w=-13/4

w=2

Answer:

The value of x is 60°, and the value of y is 50°.

Step-by-step explanation:

50°+70°+x°=180°

x=180°-120°

x=60°

similarly the angle on the left side of x will be

70°

All these angles form 180°(linear pair)

hence, 70°+60°+y°=180°

130°+y°=180°

y°=180° - 130°

y°=50°
