Which equation is true when the value of x is -12

Answers

Answer:

Which equation is true when the value of x is -12    HERE YOU GO!!

Step-by-step explanation:

tricky ... let's see ...

I notice that if we subtract xy from both sides we get

7x + xy - xy = xy - xy + 21

then

7x = 21

and

x = 21/7 = 3

so there is only one value of x that satisfies the equation

x = 3

Going back to the original equation we see that any value of y will satisfy the original equation

we can see this by rearranging things:

7x + xy - xy = 21

here, I have performed the subtraction of xy on the right side as above, but have left the left side undone

(so we don't lose the presence of y)

Note that the above can also be written as

7x + (x - x)y = 21

or

7x + 0y =21

now, since anything times zero equals zero,

y may be any number.

Let's summarize:

1) x = 3

2) y = anything

looking back at the original question;

1) the equation is true for all ordered pairs

FALSE (only one x works, not all x)

2) there are no x and y pairs for which the equation is true.

FALSE (x=3, y=anything) makes it true, i.e. (3,1)  

3) For each value of x, there is one and only one value of y that makes the equation true,

FALSE for each value of x, for the one value of x, x=3, y can be any number, which is an infinite number, not one

4) for each value of y, there is one and only on value of x that makes the equation true.

TRUE!! for all the infinite values of y you may pick, there is one and only one x you may pick, x = 3

Let A be the event that there are at least two fives among the four rolls. Let B be the event that there is at most one five among the four rolls. Find the probabilities P(A) and P(B) by finding the ratio of the number of favorable outcomes to the total (i.e., P(A) = #A #Ω and P(B) = #B #Ω ).

Answers

Answer:

P(A) = 31/1296

P(B) = 125/1296

Step-by-step explanation:

Here, we want to find P(A) and P(B)

Let’s start with A

In a roll of a die, the probability that there will be a 5 is 1/6

The probability of not having a 5 is therefore 1-1/6 = 5/6

So out of four rolls , we want to find the probability of having at least two fives

This means there could be 2, 3 or 4 fives;

For two fives;

We have 2 fives and two non-fives

= (1/6 * 1/6 * 5/6 * 5/6) = 25/1296

For 3 fives;

we have 3 fives and 1 non five

= 1/6 * 1/6 * 1/6 * 5/6 = 5/1296

For 4 fives;

= 1/6 * 1/6 * 1/6 * 1/6 = 1/1296

So the probability of at least two fives is;

1/1296 + 5/1296 + 25/1296 = 31/1296

Event B is the probability that there is at most one five among the four rolls

That means there are 3 non fives and 1 five

P(B) = 1/6 * 5/6 * 5/6 * 5/6 = 125/1296

determine the effects on the graph of the parent function f(x)=x+10 when g(x)=0.3f(x)

Answers

Answer:

First, remember the definition of a vertical contraction/dilation.

If we have a function f(x), and we dilate it with a factor A, such as:

g(x) = A*f(x).

If A is larger than 1, then we are dilating the graph of f(x)

if A is smaller than 1, then we are contracting the graph of f(x).

In this case we have:

f(x) = x + 10 and g(x) = 0.3*f(x) = 0.3*x + 0.3*10 = 0.3*x + 3.

A = 0.3

then we have a contraction.

From this, we can conclude that the effects of this transformation in the graph will be that the graph of g(x) will be a vertical contraction of the graph of f(x).

(Where contracting means that in a given interval [x1, x2] the associated interval [f(x1), f(x2)] will be larger than [g(x1), g(x2)])

Below you can see both graphs, and see the difference between them, where green is f(x) and blue is g(x)

So I was ordering me food that cost $16.13. And I have $15 and 4 quarters, 1 dime and 5 pennies. How can I make it work? Can I use the extra dollar with the 4 quarters so that I have $16?

Yes that would work since 4 quarters equals a dollar, 1 dime is equal to 10 cents and 5 pennies is equal to 5 cents and all of those added up is equal to $16.15, so you would have 2 cents in change.

Technically, it already works because you have $16.15

Item 1 Find the volume of the prism. A rectangular prism with length of start fraction 4 over 5 end fraction millimeter, width of one-half millimeter, and height of start fraction 3 over 8 end fraction millimeter. The volume is $$ cubic millimeter.

Answers

Answer:

The volume of the rectangular prism is 3/20 (or 0.15) mm³.

Step-by-step explanation:

The volume of the rectangular prism can be calculated as follows:

[tex] V = l*w*h [/tex]     (1)

Where:

l: is the length = 4/5 mm

w: is the width = 1/2 mm

h: is the height = 3/8 mm  

By entering the values of l, w, and h into equation (1) we can find the volume:

[tex] V = l*w*h = \frac{4}{5} mm*\frac{1}{2} mm*\frac{3}{8} mm = \frac{3}{20} mm^{3} = 0.15 mm^{3} [/tex]

Therefore, the volume of the rectangular prism is 3/20 (or 0.15) mm³.

Answers

Answer: x=12

Step-by-step explanation:

20 squared= 400 and 16 squared= 256. The Protagorean Theorm is a sqaured plus b sqaured equals c squared. You just reverse the Theorm to C sqaured minus B squared= A squared. 400-256=144 (12x12= 144)

Answer:
x=12

Explanation:
To solve this question, we need to use the equation a^2+b^2=c^2.

A and B are the sides of the right triangle that are perpendicular to each other and C is the diagonal side. So, in this case, a=16, b=x and c=20.

1) plug values into the equation
a^2+b^2=c^2
16^2+x^2=20^2
2) expand the squares
256+x^2=400
3) Subtract both sides by 256
x^2=400-256
x^2=144
4)Square root both sides
x=12

Substituting our data into the expression we have

17.5=125*R

R=17.5/125

R=0.14 ohms

Hence the current is 0.14 ohms
