I don't know how to plug in 1,5,10 for a function

Mathematics

explanation:

in regular math: if the function is written as function notation, replace all x's in the expression with your number and solve.

in brainly: click the math button, {it looks like a square root sign with an x inside} press whichever function or process you like and in the text box it should say something like " /[operation]{x}{y} "

in those curly brackets around x and y is where your numbers should go. just get rid of the variable and put it in your number to make the function/process they way you want it to go instead of having those placeholder variables.

Tobin is solving the equation 3(x - 1.25) = 11.25. His work is shown below.

castortr0y [4]

Answer: In the last steps, instead of multiply each side by 3, he has to divide each side by 3.

Step-by-step explanation:

Hi, Tobin makes the mistake in the last steps.

3(x-1.25) = 11.25

3x-3.75= 11.25

3x-3.75+3.75= 11.25+3.75

3x = 15

Until this step is the work ok.

Now, instead of multiply each side by 3, he has to divide each side by 3:

So:

3x /3 = 15/3

x = 5

Feel free to ask for more if needed or if you did not understand something.

Why is 1/8 cup equal to 1 fluid ounce

guapka [62]

Answer:

because there are 8 fluid ounces in a cup

Step-by-step explanation:

1/8 of cup = 0.125 cup = 1 fluid ounce

2/8 of cup = 0.25 cup = 2 fluid ounce

3/8 of cup = 0.375 cup = 3 fluid ounce

4/8 of cup = 0.5 cup = 4 fluid ounce

5/8 of cup = 0.625 cup = 5 fluid ounce

6/8 of cup = 0.75 cup = 6 fluid ounce

7/8 of cup = 0.875 cup = 7 fluid ounce

8/8 of cup = 1 cup = 8 fluid ounce

A grasshopper jumps off a tree stump. The height, in feet, of the grasshopper above the ground after t seconds is modeled by the

klasskru [66]

Answer:

Hence, Grasshopper will land on the ground after 1.5 sec.

Step-by-step explanation:

It s given that:

The height, in feet, of the grasshopper above the ground after t seconds is modeled by the function:

$h(t)=-t^2+\dfrac{4}{3}t+\dfrac{1}{4}$

Now we are asked to find:

In how many seconds will the grasshopper land on the ground?

i.e. we have to find the value of t such that h(t)=0

i.e.

$-t^2+\dfrac{4}{3}t+\dfrac{1}{4}=0$

i.e. we need to find the roots of the given quadratic equation.

On solving the quadratic equation or plotting it's graph we could observe that the point where h(t)=0 are:

$t=-\dfrac{1}{6},t=\dfrac{3}{2}$

As time can't be negative hence we will consider:

$t=\dfrac{3}{2}=1.5sec$

Hence, grasshopper will land on the ground after 1.5 sec.

If KM = 32 units, KL = 3x+6 and LM= 11 units, what is the value of x?

Rus_ich [418]

Answer:

Step-by-step explanation:

|<------------------- 32 units ---------------->|

K-----------------------L-------------------------M

3x + 6 11

KL + LM = KM

3x + 6 + 11 = 32

3x = 32 - 11 - 6

x = 15 / 3

x = 5 units
