Answer:

Step-by-step explanation:

You see that 't' is the 'argument' or 'input' to h: h(t). It is always safe to assume that t is the independent variable and h is the depend

Answer:

$.$

Step-by-step explanation:

<h2><u>IdEnTiTy UsED</u></h2>

${x}^{2} - {y}^{2} = (x + y)(x - y)$

1)

$(x - 5)(x - 5)$

=(x-5)²

2)

$(3x - 2)(3x + 2)$

${(3 x)}^{2} - {(2)}^{2}$

$= 9 {x}^{2} - 4$

3)

$(1+x)(1+x)$

= (1+x)²

GuDViN [60]

Answer:

At the end of the party <u>5.5 gallons or 88 cups</u> of punch will be leftover.

Step-by-step explanation:

Given:

There are 20 guest at a party.

Now, to find the quantity of punch that will be leftover.

Number of guests = 20.

Total gallons of punch = 8.

Now, using conversion factor we change gallons into cups:

1 gallon = 16 cup.

So, 8 gallons = 16 × 8 = 128 cups.

<u><em>Thus, total cups of punch = 128.</em></u>

Total number of cups each guest will drink = 2.

Now, to get total number of cups the 20 guests will drink by multiplying:

$20\times 2$

$=40\ cups.$

<u><em>Total number of cups the 20 guests will drink = 40.</em></u>

So, to get the leftover punch we subtract the total number of cups the 20 guests will drink from total cups of punch:

$128-40\\\\=88\ cups.$

So, 88 cups = $88\div 16=5.5\ gallons.$

Therefore, at the end of the party 5.5 gallons or 88 cups of punch will be leftover.

What is 0.04 is 1/10 of what number ?

Simora [160]

$0.04= \frac{4}{100}\to\frac{1}{25} \\\\ \frac{1}{10} \ of \ x= \frac{1}{25} \\\\ \frac{1}{10}*x=\frac{1}{25} \\\\ \frac{x}{10}=\frac{1}{25} \\\\ \boxed{x=\frac{10}{25}\to\frac{2}{5}}$

Solve the system<br> y= 3x+7<br> y=2x-3

notka56 [123]

Answer:(-10,-23)

Step-by-step explanation:

Okay....the easiest way to answer this would be either elimination or graphing. However, you could also use substitution.

Right now, I'll show how to use it by elimination.

First this is to convert both equations to standard form (x+y=__)

What we'll do for the first one is add 3x to each side. We end up with this:

-3x+y=7

Then subtract 2x from the other one. Ending up with:

-2x+y=-3

Now, we eliminate the y by subtracting.

-3x+y=7

(-) -2x+y=-3

___________

-x =10

x = -10

Now, plug in the x to one of the equations.

y=2(-10)-3

y=-20-3

y=-23

Make sure to check your answer by plugging both into the equations.

X=-10

Y=-23
