Answer:

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

Step-by-step explanation:

let [tex]f^{-1} (x)[/tex] = y

then f(y) = x

2y-4 =x

2y =x+4

y= x/2 +2

hence f^{-1} (x) = x/2 +2

Answer:

the answer is A). y=1/3×-52

Answer:

i believe the answer is...C

Step-by-step explanation:speed(memory) or s(m)

Step-by-step explanation:

Dependent variable states that  a variable whose value dependent upon the dependent variable.

For example:

x is the independent variable and f(x) is the dependent variable

Given the statement:

The speed of a computer depends on the amount of memory.

Let m represents the amount of memory and s represents the speed of a computer.

m = Independent variable

s(m) = Dependent variable on m

Then

Answer:speed (memory), or s(m)

Answer:

Simone is correct

Step-by-step explanation:

Given

Line 1:

[tex](x_1,y_1) = (-2, 7)[/tex]

[tex](x_2,y_2) = (3, 0)[/tex]

Line 2:

[tex](x_1,y_1) = (2, 1)[/tex]

[tex](x_2,y_2) =(12, -13)[/tex]

Required

Is Simone correct?

Slope (m) is calculated using:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

For Line 1

[tex]m = \frac{0 - 7}{3 - (-2)}[/tex]

[tex]m = \frac{0 - 7}{3 +2}[/tex]

[tex]m = \frac{-7}{5}[/tex]

[tex]m = -\frac{7}{5}[/tex]

For Line 2:

[tex]m = \frac{-13 - 1}{12 -2}[/tex]

[tex]m = \frac{-14}{10}[/tex]

Divide by 2/2

[tex]m = \frac{-14/2}{10/2}[/tex]

[tex]m = \frac{-7}{5}[/tex]

[tex]m = -\frac{7}{5}[/tex]

By comparison, both lines have the same slope.

Hence, Simone is correct

Answer:

-6

Step-by-step explanation:

because the roots are the x values of where the function crosses the x axis

so thats at -2 and 3

and product is multiplication

so -2×3= -6

Answer:

The roots/zeroes are where the x-values where the graph touches or passes through the x-axis..They are at -1 and 3. So your answer would be a) -1

Answer:

the anser is 64 cups

Step-by-step explanation:

half gallon is 8 cups and she bought 8 of them so multiply 8 and 8 or 8^2 and you get 64

pls mark brainliest

Answer:

A. 64 cups

Step-by-step explanation:

There are 16 cups per gallon, so a half gallon would be 8 cups. If she bought 8 bottles that means you must take the 8 bottles times the 8 cups per bottle or just 8*8=64. Answer A. is 64 cups.

Step-by-step explanation:

Answer:

28.76 °F

Step-by-step explanation:

The temperture of sea ice frozen ocean water is about -1.8 °C .

We are to convert to a temperture in fahrenheit using the formula F=(c) (9/5)+32

°C = -1.8°C

°F=(c) (9/5)+32

= [(-1.8°C × 9/5) + 32]°F

= [-16.2/5 + 32]°F

= [-3.24 + 32]°F

= 28.76°F

Answer:

(2, 7)

Step-by-step explanation:

( 1 ) Find by using a formula of (-b/2a, (4ac-b²)/4a)

[tex](\frac{-b}{2a},\frac{4ac-b^2}{4a})\\(\frac{-12}{2(-3)}),(\frac{4(-3)(-5)-(12)^2}{4(-3)})\\(\frac{-12}{-6}),(\frac{60-144}{-12})\\(2,\frac{-84}{-12})\\(2,7)[/tex]

The vertex is at (2,7)

( 2 ) Find by using a derivative (Calculus)

You can also find a vertex by using a calculus. Using a derivative

[tex]y'=-3x^2+12x-5\\y'=-6x+12\\\\[/tex]

Then substitute y' = 0 to get a vertex.

[tex]y'=-6x+12\\0=-6x+12\\-12=-6x\\2=x[/tex]

Then substitute x = 2 in the equation of y = -3x²+12x-5

[tex]y=-3x^2+12x-5\\y=-3(2)^2+12(2)-5\\y=-3(4)+24-5\\y=-12+24-5\\y=-17+24\\y=7[/tex]

x = 2 and y = 7, therefore. The vertex is (2,7)

Answer:

A.) x / 3 = 12      ----> x = 12(3)   ----> x = 36

B.) 2x + 3 = 20  ----> 2x = 17 ----> x = 17/2

C.) 4/3x = 10/3 ----> x = 10/3 x 3/4 ----> x = 30/12 = 5/2

D.) -4x = -24 ----> x = -24/-4 ----> x = 6

E.) 2(x-4) = 10 ----> 2x - 8 = 10 ----> 2x = 18 ----> x = 9

F.) -0.5x + 1.1 = -2.9 ----> -0.5x = -4 ---> x = -4 / -0.5 ----> x = 8

Answer:

Your answer is 6.

Step-by-step explanation:

Substitute the value of the variable into the equation and simplify.

Answer:

6

Step-by-step explanation:

when you substitute 3 in for x you get 3(3) - 3

solve the equation

3(3) = 9

9 - 3 = 6

Answer:

C

Step-by-step explanation:

Lines that are parallel AND have different y-intercepts will never intersect each other, therefore will have no solutions.

The only correct choice is C as the lines are parallel and have different y-intercepts which means they'll never intersect each other. All the other choices will have their lines intersect each other at some point.

Answer:

3.8

Step-by-step explanation:

Slope formula- m = y2 - y1

Step-by-step explanation:

Answer:

The y-intercept is 16, which represents the original depth of snow on the lawn

Step-by-step explanation:

t is the time in hours where the snow melted, so 16 was the original amount of snow on the ground before it melted over time.

The y-intercept is 16 inches. Then the y-intercept represents the height of the snow initially.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Eli noticed a lot of snow on his front lawn towards the conclusion of a snowstorm. As the weather rose, the snow began to melt at a steady pace. The depth of snow on Eli's lawn in inches may be calculated using the equation S = 16 - t, where t is the time after the snow ceased falling in hours.

Compare the equation with the standard equation, then we have

c = 16

The y-intercept represents the height of the snow initially.

it will be written as 5.1×10^9

Answer:

yes

Step-by-step explanation:

A number in scientific notation consists of the product of a number from 1 to under 10 and an integer power of 10.

5.1 is a number from 1 to under 10.

10^9 is an integer power of 10.

Therefore, 5.1 * 10^9 is a number written in scientific notation.
