do you inverse to slove
Answer: Yes, In mathematics, an inverse function (or anti-function) is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g(y) = x.
What is the slope and y-intercept of the equation 6x - 1 = 3y - 10?*
(1 Point)
Om = 2, b = 3
O m = 3, b = 4
m = 6, b = 9
Answer:
m = 2, b = 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Given
6x - 1 = 3y - 10 ( add 10 to both sides )
6x + 9 = 3y ( divide all terms by 3 )
2x + 3 = y , that is
y = 2x + 3 ← in slope- intercept form
with slope m = 2 and y- intercept b = 3
Expand.
If necessary, combine like terms.
(2x + 5)(x – 5) =
To Expand: (2x + 5)(x - 5).
(2x + 5)(x - 5)
= 2x(x - 5) + 5(x - 5)
= 2x² - 10x + 5x - 25
= 2x² - 5x - 25 Ans.
(Combined the like terms)
Answer:
2x² - 5x - 25
Step-by-step explanation:
Use FOIL method
(2x + 5)(x - 5) = 2x*x + 2x*[-5] + 5*x + 5*[-5]
= 2x² -10x + 5x - 25 {add like terms}
= 2x² - 5x - 25
I know the answer is .78, but don’t understand why? .9-.6X.2
Step-by-step explanation:
When you multiply 0.6 and 0.2, you do not get 1.2. Rather, the product would be 0.12.
We have the equation [tex]0.9-(0.6)(0.2)[/tex]
To show you what is happening, lets convert these numbers into fractions
This would give us [tex]\frac{9}{10} -(\frac{6}{10})(\frac{2}{10})[/tex]
Recall that when you multiply two fractions, you multiply the numerators and denominators separately. Doing so gives us
[tex]\frac{9}{10} -\frac{6*2}{10*10}[/tex]
Which then becomes
[tex]\frac{9}{10} -\frac{12}{100}[/tex]
The last thing we need to do is to create a common denominator
[tex]\frac{90}{100}-\frac{12}{100}=\frac{78}{100} =0.78[/tex]
Another way to see what is happening is by thinking about the numbers in scientific notation. Doing so would give us
[tex]9*10^{-1}-(6*10^{-1})(2*10^{-1})[/tex]
Once we multiply these terms, we get
[tex]9*10^{-1}-6*10^{-1}*2*10^{-1}\\\\9*10^{-1}-12*10^{-2}[/tex]
Now we can convert these numbers into decimals to get
[tex]0.9-0.12=0.78[/tex]

the difference between objects being "similar" vs. "congruent
Answer: See below
Step-by-step explanation:
The difference between similar and congruent is the size and shape.
If two objects are similar, they look similar to each other, meaning they look the same, but not exactly the same. It can be 2 stuffed animals that look the same, but different sizes. One can be large and other can be small.
If two objects are comgruent, you know that they are EXACTLY the same. They are the same size, shape, etc. Using the example from above, you have either two large stuffed animals, or two small stuffed animals. The two large animals would be congruent to each other, same for the small animals.
Congruent means that they are identical. They are exactly the same in every way.
Similar can mean they look the same but they are not identical.
For example, a triangle that has been scaled down in size is still similar to the original triangle but they are not congruent.
I believe thats what it is.

Which of the following values are solutions to the inequality 10+ x > 7?
I. – 7
II. - 1

Answer:
II
Step-by-step explanation:
All the other options create a number that is smaller than 7, while the inequality suggests otherwise.
While, II create the number 9 - which is indeed bigger then 7

Answer:
[tex]x=\frac{-3d-9}{k-d}[/tex]
Step-by-step explanation:
Step 1: Write out equation
d(-3 + x) = kx + 9
Step 2: Distribute
-3d + dx = kx + 9
Step 3: Subtract dx on both sides
-3d = kx - dx + 9
Step 4: Subtract 9 on both sides
-3d - 9 = kx - dx
Step 5: Factor
-3d - 9 = x(k - d)
Step 6: Divide both sides by k - d
[tex]x=\frac{-3d-9}{k-d}[/tex]
Answer:
Step-by-step explanation:
Step 1: Write out equation
d(-3 + x) = kx + 9
Step 2: Distribute
-3d + dx = kx + 9
Step 3: Subtract dx on both sides
-3d = kx - dx + 9
Step 4: Subtract 9 on both sides
-3d - 9 = kx - dx
Step 5: Factor
-3d - 9 = x(k - d)
Step 6: Divide both sides by k - d

Which of the following statements best gives the reasons that a data usage bill for a smart phone is an essential (variable) expense? a. It is an obligation to pay, but the spender has some control over its amount. b. It cannot be eliminated in a later budget, in order to save money. c. It is expected to be the same amount every month. d. Bills for services rendered have a higher priority than any other type of expense. Please select the best answer from the choices provided A B C D
Answer: I’m pretty sure its A on e2020
Step-by-step explanation:
It is an obligation to pay, but the spender has some control over the amount.
Option A is the correct answer.
We have,
The reason that a data usage bill for a smartphone is an essential (variable) expense is that it is an obligation to pay.
In other words, the phone service is necessary for the phone to function properly, and therefore, the bill must be paid.
However, the spender has some control over its amount by managing their data usage, such as turning off data for certain apps or using Wi-Fi instead of cellular data.
This means that while the bill cannot be eliminated entirely, the spender can take steps to reduce the amount owed.
Statement b is incorrect because while the bill cannot be eliminated entirely, it can be reduced by managing data usage.
Statement c is incorrect because the amount of the bill is not expected to be the same every month, as it will depend on how much data is used. Statement d is incorrect because while bills for services rendered may be a priority, they do not necessarily have a higher priority than other types of essential expenses, such as food or housing.
Thus,
It is an obligation to pay, but the spender has some control over the amount.

Solve for n.
d=2m +3n
Answer:
n= 1/3d - 2/3m
Step-by-step explanation:
d=2m+3n
Step 1: Flip the equation.
2m+3n=d
Step 2: Add -2m to both sides.
2m+3n+−2m=d+−2m
3n=d−2m
Step 3: Divide both sides by 3.
3n/3 = d-2m/3
Therefore
n= 1/3d - 2/3m
Hope this helps!
Plz name brainliest if possible.
Answer:
n = d - 2m
3*
Step-by-step explanation:
First we want to get n alone on one side, so we should subtract 2m from both side;
d = 2m + 3n
3n = d - 2m
Now to get n by itself, we need to divide by 3 from both sides;
3n = d - 2m
n = d - 2m
3*
*Pretend there is a fraction bar between d - 2m and 3
