Answer: You will be charged $ 210 for 10 GB of data.

Step-by-step explanation:

Given : Cost of cell phone plan = $90

Additional charge over 4GB for each GB =  $20

If 10 GB data is used , then after 4 GB you need to pay for 6 additional GB (10-4=6)

Total charge = (Cost of cell phone plan)+ (Additional charge) x (Number of gigabytes over 4 GB)

i.e. Total charge = $(90+20(6))

= $ (90+120)

= $ 210

Hence, you will be charged $ 210 for 10 GB of data.

Answer:

6 boxes, 3 books

Step-by-step explanation:

Samantha has 45 books

She can pack 7 books in each box

The number of box she can completely fill can be calculated as follows

= 45/7

= 6 remainder 3

Hence Samantha can completely fill 6 boxes and will still be left with 3 books

Answer:

heres an example: Replace all x's in

g(x)

with the function f(x) to get

g(f·x)=(x+3)2

Explanation:

g(f·x)

means that you replace all x's in

g(x)

with the function

(f·x)

The easiest way to do this is rewrite

g(x)

replacing all x's with a blank set of parenthesis, like this

-g(f·x)=(x)2

Now place the function into the parenthesis.

(f·x)

g(f·x)=(x+3)2

Step-by-step explanation:

you would change it to 90-x=x because the angles are congruent and then add x on both sides until it is 90=2x, divide 2 from both sides to get 45=x

A long jump competition was held at Barangay Mathalino John Mark

jumped 2/3 of 6 3/5 meters of the field. How far did John Mark jump​?

Answer:

4 2/5 meters

Step-by-step explanation:

We are told:

John Mark jumped 2/3 of 6 3/5 meters of the field.

The distance John jumped us calculated as:

2/3 × 6 3/5 meters

Converting 6 3/5 meters to mixed fraction

= 33/5 meters

Hence, John jumped

=2/3 × 33/5 meters

= 22/5 meters

= 4 2/5 meters

Answer:

Here we are given with a graph.

we have been asked to find the value of x for which

As we know that , to find the value of x for the given value of f(x), we need to look onto the vertical axis, and mark a dot on the given value now draw a line perpendicular to vertical axis so that it cut the given straight line, and where they intersect draw another line perpendicular to the horizontal axis and you will get the value where it crosses the horizontal axis.

We get x=5, then f(x)=7.

Plsss give me brainliest :)

Note: The function is not an equation. I will form and solve an equation to answer the question.

Answer:

C. Two real solutions

Step-by-step explanation:

We have the following function:

f(x)=2(x-1)^2+4

It does not form an equation to solve, and therefore, there are no 'solutions'. We must equate the function to something to set a condition and solve it. We'll complete the equation.

Solve for x when:

f(x)=12

Substituting the function:

2(x-1)^2+4=12

Subtracting 4:

2(x-1)^2=8

Dividing by 2:

(x-1)^2=4

Taking square root:

x-1=\pm\sqrt{4}

Solving:

x=1\pm2

We have two real solutions x=3 and x=-1

Note if we had equated to 4, then the equation would have had only one real solution, and if we had equated to 0, we would have two complex solutions.

The solution of equation f(x) = 2x² - 4x + 6 is two complex solutions. Then the correct option is B.

The discriminant of a quadratic is a number that depends on the components and allows some characteristics of the roots to be deduced without calculating them.

The quadratic equation is ax² + bx + c = 0. Then the discriminant is given as,

D = b² - 4ac

The equation is given below.

f(x) = 2(x - 1)² + 4

f(x) = 2x² - 4x + 2 + 4

f(x) = 2x² - 4x + 6

The discriminant is given as,

D = (-4)² - 4×2×6

D = 16 - 48

D = - 32

D < 0

The roots are complex root.

The solution of equation f(x) = 2x² - 4x + 6 is two complex solutions. Then the correct option is B.

Step-by-step explanation:

ω = ω₀ + αt

θ = ω₀ t + ½ αt²

We need to eliminate t from the system of equations.  Solve for t in the first equation, then substitute it into the second equation.

t = (ω − ω₀) / α

θ = ω₀ (ω − ω₀) / α + ½ α ((ω − ω₀) / α)²

θ = ω₀ (ω − ω₀) / α + ½ (ω − ω₀)² / α

αθ = ω₀ (ω − ω₀) + ½ (ω − ω₀)²

αθ = ω₀ω − ω₀² + ½ (ω² − 2ω₀ω + ω₀²)

αθ = ω₀ω − ω₀² + ½ ω² − ω₀ω + ½ ω₀²

αθ = ½ ω² − ½ ω₀²

2αθ = ω² − ω₀²

Answer:

f(x)=23/8

Step-by-step explanation:

To find horizontal asymptotes: If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0). If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.

Add -4y to both sides.

3x + 4y + −4y = 10 + −4y

3x = −4y + 10

Divide both sides by 3.

3x /3  =  −4y + 10 /3

x=  −4 /3 y +  10 /3

Answer: x=  −4 /3 y +  10 /3

Answer: 160 minutes

Step-by-step explanation: 200 divided by 5 is 40, then 40 times 4 is 160

Division is one of the four fundamental arithmetic operations. The time it will take Robin to read 200 pages of the book at the same rate is 160 minutes.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that it takes Robin 4 minutes to read 5 pages of a book. Therefore, the rate at which Robin reads a page of the book is,

Rate at which Robin reads = 4 minutes/5 pages = 0.8 minutes per page

Now, to know the time it will take for Robin to read the book of 200 pages at the same rate can be found by multiplying the number of pages by the rate of reading. Therefore, the rate at which Robin reads is,

Time to read 200 pages = 0.8 minutes per page × 200 pages

                                         = 160 minutes

Hence, the time it will take Robin to read 200 pages of the book at the same rate is 160 minutes.

Step-by-step explanation:

Answer:

f(-4) = 4

Step-by-step explanation:

Let the equation of the function is,

f(x) = mx + b

where m = slope of the line

b = y-intercept of the line

From the graph attached,

Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex] = [tex]\frac{-2}{4}[/tex]

Slope 'm' = [tex]-\frac{1}{2}[/tex]

y-intercept 'b' = 2

Therefore, function will be,

f(x) = [tex]-\frac{1}{2}x+2[/tex]

For x = -4,

f(-4) = [tex]-\frac{1}{2}(-4)+2[/tex]

      = 2 + 2

      = 4

Which is true from the graph.
