7x-130=110+9x. show with steps

Answers

Answer:

x=-120

Step-by-step explanation:

7x-130=110+9x

add 130 to both sides of the equation

7x-130+130=110+9x+130

Simplify

7x=9x+240

Subtract 9x from both sides

7x-9x=9x+240-9x

Simplify

-2x=240

divide both sides by -2

-2/-2=240/-2

simplify

x=-120

7x-130=110+9x
-7x -7x
-130=110+2x
-110 -110
-240=2x

An end behavior model for f(x) =​

Answers

Answer: Choice C) 2x^4

=====================================================

As x gets larger and larger, all we really care about is the leading terms. This is because 8x^6 is much larger than -16x^3 and 8 for very very large x values. The larger the exponent, the larger the result will be.

So effectively, the leading term 8x^6 dictates the end behavior for the numerator.

In a similar way, the leading term 4x^2 dictates the end behavior for the denominator polynomial.

Divide the two leading terms:

(8x^6)/(4x^2) = (8/4)*x^(6-2) = 2x^4

The rule used here is (a^b)/(a^c) = a^(b-c)

So as x goes to infinity or negative infinity, it's slowly approaching the asymptote y = 2x^4.

why is math hard and important​

Answers

Answer: Math seems difficult because it takes time and energy. Many people don't experience sufficient time to "get" math lessons, and they fall behind as the teacher moves on. Many move on to study more complex concepts with a shaky foundation. And then often end up with a weak structure that is doomed to collapse at some point.

Step-by-step explanation: math is important because some things in math are gonna be used in your daily life for example adding, subtracting, division Etc and also because Math helps us think analytically and have better reasoning abilities. Analytical thinking refers to the ability to think critically about the world around us. Analytical and reasoning skills are essential because they help us solve problems and look for solutions.

true or false, the ratios 4:10 and 8:20 are equivalent


PLEASE HELP IF I FAIL MY MOM IS GONNA-

Answers

Answer:

True

Step-by-step explanation:

If you multiply both 4 and 10 by two, you get 8 and 20

The ratios 4:10 and 8:20 are Equivalent.

What is ratio?

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

As, when the two ratios are equal after simplifying then they are equivalent ratio.

So, 4/10

= 2/5

and, 8/20

= 2/5

As, both ratios are giving equal value after simplifying.

determine if the equation is true x = 8
2x - 6 = 9

Answers

Answer:

False

Step-by-step explanation:

This is false because:

1) In order to solve this, we cam use the addition property of equality

2) First, you can add 6 to -6 and 9

New Equation: 2x = 15

3) Now divide 2 with 2 and 15

New Equation: x = 7.5

You can also check by inserting 8 into the equation.

2(8) - 6 = 9

16 - 6 = 9, this is not true.

Therefore, this statement is false. x = 7.5

A payment of $35.20 is automatically deducted each month for her gym membership. If she makes no other deposits or withdrawals, how much money is in Erica’s account at the end of four months?

Answers

Erica will have $309.2 left in her mani account after 4 months
Answer:
$309.20

Explanation:
We know that..
- Erica started off with $450 in her bank account
- $35.20 gets taken out of her bank account every month

Using this information, we can write an equation:
E = 450-35.2m

E= the amount of money Erica has
m= the number of months that pass

And now, all we have to do is substitute m as 4 to find out how much money is in Erica’s account after 4 months.

E = 450-35.2m
E=450-35.2(4)
E=309.2

Therefore, there would be $309.20 left in Erica’s bank account after 4 months.

Use the graph to determine which statement describes f(x)
O A. f(x) does not have an inverse function, because its graph fails the
horizontal line test.
O B. f(x) has an inverse function, because its graph passes the
horizontal line test.
C. f(x) has an inverse function, because its graph passes the vertical
line test.
D. f(x) does not have an inverse function, because its graph fails the
vertical line test.

Answers

Answer:

f(x) does not have an inverse function, because its graph fails the horizontal line test. ⇒ A

Step-by-step explanation:

The vertical line test is used to show that the graph represents a

function or not

If the vertical line crosses the graph in more than one point, then the graph does not represent a functionIf the vertical line crosses the graph in only one point in different positions, then the graph represents a function

The horizontal line test is used to show that the function has an

inverse or not

If the horizontal line crosses the graph of a function in more than one point, then the function has no inverseIf the horizontal line crosses the graph of a function in only one point in different positions, then the function has an inverse

Let us look at the given graph

→ The graph represents a parabola, which represents the function f(x)

∵ Any horizontal line drawn will cross the graph in more than one point

∴ f(x) has no inverse

f(x) does not have an inverse function, because its graph fails the

  horizontal line test.
