Answer:

35x/4

Step-by-step explanation:

Answer:

35 / 4 ( in fraction ) or 8.75 ( in decimal )

Step-by-step explanation:

7/8 x 10

= ( 7 x 10 ) / 8

= 70 / 8

= 35 / 4

  ( or )

= 8.75

Answer:

The X is equal to 1.75

Step-by-step explanation:

3.5X2.25=7.875

14/7.875=1.75

Answer: x=1.75

Step-by-step explanation:

rearrange the term: 3.5 (2.25 + x) = 14

the new term: 3.5 (x + 2.25) = 14

Combine multiplied terms into a single fraction, then distribute.  

x = 1.75

The number of decimal places you move will be the exponent on the

10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.  

Step-by-step explanation:

you just have to put the given values in place of the variable names and then simply calculate.

(-2² + 2²) - 2(-2² - 2²) = (4 + 4) - 2(4 - 4) = 8 - 2×0 = 8

so, B is the right answer.

please remember the correct sequence of operations :

first are brackets.

then exponents.

then multiplications and divisions.

and then (at last) additions and subtractions.

and also please remember : multiplying a negative number with a negative number creates a positive result.

that is of course also true for squaring a negative number, as ² just means that the negative number is multiplied with itself.

now you also know the result of -2³, right ?

as this means -2 is multiplied 3 times by itself. what does that do to the sign ?

-2 × -2 = 4 (positive).

but now we have to multiply a third time

4 × -2 = -8 (because multiplying a positive number with a negative number creates a negative result).

The range for the given scenario is y≥0.

Given that, Tina graphed the function on the coordinate grid to show f(x), the height of the dropped ball, in feet, after its xth bounce.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Part A:

From the graph we can see that, for f(3) that is for 3 bounces the height is 4 feet.

Part B: Tina said that a possible range for the given function is y > 0.

From the graph we can see that for f(7) and f(8), the ball is almost at rest position. So the range can be y≥0.

Therefore, the range for the given scenario is y≥0.

2(8y+1/2) would be equal to 2x8y+2x1/2=16y+1.

2(8y+1/2) would also be equal to 8y+1/2+8y+1/2 because multiplying by 2 is basically just adding the thing you are multiplying to itself.

Answer:To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).

Answer:

Y = 1/2x + 2

Step-by-step explanation:

First you find (b) or the Y-intercept which is 2 (Y = mx + 2)

Then you do rise over run to find slope. Rise = 1. Run = 2. Slope (m) = 1/2

Now you have your answer Y = 1/2x + 2
