Answer 1
Explanation: To find the value of x, you have to isolate it on one side of the equation. You can do this by adding or subtracting the number near it, or dividing by its coefficient.

The steps for solving for x are to-
1) Simplify any numbers on one side that can be simplified
Example: 2x + 1 + 2 = 7 In this, 2 and 1 can be simplified to make 3 because they are both whole numbers. This can also be done with coefficients, like adding 4x and 6x on one side of the equation because they have the same variable.
2) Add or subtract the constants from the side with x.
Example: 2x + 3 = 7. Here, you would subtract 3, the constant, from both sides to isolate the x. The answer would be 2x = 4.
3) Divide by the coefficient.
Example: 2x = 4. Here, the coefficient is 2, because it’s the number next to the variable x. You’d divide it from both sides to get the answer x = 2.

Answers:

2x - 5 = 11
Here, to get rid of the -5, we add five to both sides of the equation to make it become 0. The reason you have to do it to BOTH sides is because you need the equation to stay equal.
2x - 5 = 11
(+5) (+5)
2x = 16
Now, the coefficient, 2, needs to be divided from both sides to isolate the x.
2x = 16
(/2) (/2)
x = 8
Here, the answer is that x = 8!


13 = -4x + 9
Here, once again, we first have to subtract from the side with the x on it before we divide. Because this number is a positive nine, we have to subtract 9 to get to zero, rather than how we added when we had a negative number.
13 = -4x + 9
(-9) (-9)
4 = -4x
Now, we are left with a coefficient of -4. When you divide this coefficient, you have to remember to keep in the negative, rather than dividing by 4.
4 = -4x
(/-4) (/-4)
-1 = x
The solution to this equation is that x = -1


7 - 3x = 34
First we have to subtract seven from both sides, because the seven in this equation is positive.
7 - 3x = 34
(-7) (-7)
-3x = 27
(Note that -3x is a negative number. This is because there was a subtraction mark in front of it.)
Now, we divide both sides by the coefficient, which is -3, to isolate the x
-3x = 27
(/-3) (/-3)
x = -9
In this equation, x is -9.


11 = x - 5 + 8
First, we simplify the (5 + 8) into one number
11 = x - 13
Then we add 13 to both sides to isolate the x
11 = x - 13
(+13) (+13)
24 = x
Because there is no coefficient, this equation ends here, and x is 24!



-14x + 3 = 12
(-3) (-3)
-14x = 9
(/-14) (/-14)
x = -9/14
Here, because you can’t make a whole number, you’d simplify the answer of x to be the fraction -9/14, because you are dividing 9 by -14.


6) To set up this equation, we have to identify the constants and coefficient.
- To start, we will use the variable x to be our unknown number for how many weeks he needs before he can buy the TV.
- We know his end goal is 1664, so that will be our answer.
- Our coefficient for x will be 60, because that’s how much money he’ll be getting each week.
- Our coefficient for the side of x will be 500, because he already has that fixed amount of money that can’t be altered by the variable x.
- Our equation will end up looking like this:
60x + 500 = 1664
(-500) (-500)
60x = 1164
(/60) (/60)
x = 19.4
Now, 19.4 isn’t a whole number. Since the number is over 19, we would round up to 20 because he needs a full week to put in the money.
So, in this equation, it would take him 20 weeks to buy the TV.


7) Let’s identify our values for this one.
The value for the unknown, how many values James can drive, will be x.
The total money he has is 250, so that will be our answer.
It costs 6$ per hour, so 6 will be our coefficient
The initial cost is 52$, so that will be the value on our x side.
The equation should look like:
6x + 52 = 250
(-52) (-52)
6x = 198
(/6) (/6)
x = 33
In this equation, James can drive his rental car for 33 hours!


8) Let’s identify the values for this one!
- Our unknown, how many hours Aislyn rented the room, will be represented by x
- Since it’s 5$ for each hour, our coefficient will by 5.
- An initial fee of 30$ means 30 will be our constant on the x side
- 50$ total means 50 will be on the opposite side of x.
The equation should look like:
5x + 30 = 50
(-30) (-30)
5x = 20
(/5) (/5)
x = 4
So, Aislyn rented the room for 4 hours!!


Hope this helps.

Answers

Answer:

-24

Step-by-step explanation:

The standard from of equation of a line is expressed as g(x) = mx+c where;

m is the slope

c is the y-intercept of the line.

Given the expression g(x)= (- 8)(x +3), rewriting in standard form first we have;

g(x)= (- 8)(x +3)

gx)= -8x - 24

On Comparing with g(x) mx+ c, we will see that;

c = -24

Hence the y-intercept of the quadratic function is -24

. Beth is making gingerbread men. She uses 2 raisins for eyes and 3 raisins for buttons for each gingerbread man. She buys 4 boxes of raisins, each with 120 raisins in it. How many dozens of gingerbread men can she make​

Answers

i think the answer is Beth can make 8 dozen gingerbread men

The number of gingerbreads that Beth can be made from 4 boxes of raisins is 8 dozens.

What is Proportion?

Proportions are mathematical statements where two or more ratios are made to be equivalent to each other.

Number of raisins Beth uses for one gingerbread man = 2 raisins for eyes and 3 raisins for buttons.

Number of raisins used for 1 gingerbread man = 2 + 3 = 5 raisins

Beth buys 4 boxes of raisins, each with 120 raisins in it.

Total number of raisins Beth bought = 4 × 120 = 480 raisins

So, 1 gingerbread can be made from 5 raisins.

Let x be the number of gingerbreads made from 480 raisins.

Using proportion,

1 : 5 = x : 480

1 / 5 = x / 480

Applying cross multiplication,

5x = 480

x = 480 / 5

x = 96

96 gingerbreads or 96/12 = 8 dozens of gingerbread can be made.

Hence 8 dozens of gingerbreads can be made from 4 boxes of raisins.

What is the population density of 13 lillies living in an area of 6 meters (length) and 4 meters (width)?

Answers

Answer:

0.54 lillies per square meter.

Step-by-step explanation:

First we calculate the area:

Area = length * width

Area = 6 m * 4 m = 24 m²

The we divide the population of lillies (13) by the area, to calculate the population density:

13 lillies / 24 m² = 0.54 lillies/m²

So the population density is 0.54 lillies per square meter.

Which function displays this end behavior?
• As xapproaches negative infinity, y approaches positive infinity.
• As xapproaches positive infinity, yapproaches negative infinity.
A.) y = (x+ 2)^3 -9
B.) y = -2x^3-1
C.) y = -3x^3 + 4
D.) y = 3(x-1)^2

Answers

The functions that displays the behavior that as x approaches -∞, y approaches ∞ and as x approaches -∞, y approaches  -∞ are:

Option B: [tex]y = -2x^3-1[/tex]Option C:  [tex]y = -3x^3 + 4[/tex]

How to find the value of the function as x approaches infinity(+ve or -ve)?

If limits exist, we can take limits of the function, where x tends to -∞ or ∞, and that limiting value will be the value the function will approach.

Testing all the four functions listed for x tending to -∞ or ∞:

Case A: [tex]y = (x+ 2)^3 -9[/tex]

1. For x approaching -∞

[tex]lim_{x \rightarrow -\infty} (y) = lim_{x \rightarrow -\infty} ((x+2)^3 - 9) = -9 + lim_{x \rightarrow -\infty} ((x+2)^3) \rightarrow - \infty[/tex]

(since cube of negative quantity is going to be negative)

Thus, function also tends to -∞. So this function doesn't satisfy first case, thus, we don't need to test other case as only that function is needed which can satisfy both the cases.

Case B: [tex]y = -2x^3-1[/tex]

1. For x approaching -∞

[tex]lim_{x \rightarrow -\infty} (y) = lim_{x \rightarrow -\infty} (-2x^3 - 1) = -1 + lim_{x \rightarrow -\infty} (-2x^3) \rightarrow \infty[/tex]

(this time, negative sign was canceled by outer negative. So function approaches positive infinity as x approaches negative infinity.

2.  For x approaching ∞

[tex]lim_{x \rightarrow \infty} (y) = lim_{x \rightarrow \infty} (-2x^3 - 1) = -1 + lim_{x \rightarrow \infty} (-2x^3) \rightarrow -\infty[/tex]

So function approaches negative infinity as x approaches positive infinity

Thus, the considered function behaves as needed.

Case C: [tex]y = -3x^3 + 4[/tex]

Similar to above cases, we can see that negative sign and cube power will make this function go to positive infinity as x approaches negative infinity, and as x approaches positive infinity, the function will approach negative infinity.

Remember that finite constants added or subtracted from arbitrary large quantities(positive or negative infinity) can't affect them.

Case D: [tex]y = 3(x-1)^2[/tex]

Here x is in square power, no matter if x approaches +ve or -ve infinity, the square term would make it positive. So this function cannot approach negative infinity.

Thus, only Option B and C are performing as needed. Therefore, the functions that displays the behavior that as x approaches -∞, y approaches ∞ and as x approaches -∞, y approaches  -∞ are:

Option B: [tex]y = -2x^3-1[/tex]Option C:  [tex]y = -3x^3 + 4[/tex]
