Answer:

Step-by-step explanation:

a formula

7(x - 2) = 5(x + 4)

Multiply the first bracket by 7

(7)(x)=7x

(7)(-2)=-14

Multiply the second bracket by 5

(5)(x)=5x

(5)(4)=20

7x-14=5x+20

Move 5x to the other side. Sign changes from -5x to +5x.

7x-5x-14=5x-5x+20

7x-5x-14=20

2x-14=20

2x-14+14=20+14

2x=34

Divide both sides by 2

2x/2=34/2

Answer: x=17

Answer:

7(x-2)=5(x+4)

Answer:

[tex]\frac{x^2}{9}[/tex] - 4x + 36

Step-by-step explanation:

([tex]\frac{x}{3}[/tex] - 6)² = ([tex]\frac{x}{3}[/tex] - 6)([tex]\frac{x}{3}[/tex] - 6)

Each term in the second factor is multiplied by each term in the firs t factor, that is

[tex]\frac{x}{3}[/tex]([tex]\frac{x}{3}[/tex] - 6) - 6([tex]\frac{x}{3}[/tex] - 6)

Distribute both parenthesis

= [tex]\frac{x^2}{9}[/tex] - 2x - 2x + 36 ← collect like terms

= [tex]\frac{x^2}{9}[/tex] - 4x + 36

Answer:

- 1050

Step-by-step explanation:

The sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ], thus

[tex]S_{20}[/tex] = [tex]\frac{20}{2}[/tex] [ (2 × - 74) + (19 × - 3) ]

= 10 ( - 148 - 57) = 10 × - 105 = - 1050

Answer:

If x-2 is a factor of p(x) = x^{4} - 3 x^{2} + 2 x - 8 ,then p(x)  = 0

Solution:

According to factor theorem of polynomials,  

x-a is a factor of polynomial p(x), if and only p(a)=0

Step 1:

Since x-2 is factor of p(x),

x - 2 = 0

x = 2

Step 2:

[tex]p(x) = x^{4} - 3 x^{2} + 2 x - 8 ------ (equation 1)[/tex]

By substituting x = 2 in equation 1,

[tex]p(x) = 2^{4} - 3(2)^{2} + 2(2) - 8[/tex]

p(x) = 16 - 3(4 ) + 4 -8

p(x) = 16 - 12 - 4

p(x) = 16 - 16

p(x) = 0

Since x - 2 is a factor of p(x)  , we get p(x)=0

[tex]\huge\boxed{\text{1. False}}[/tex]

Integers are the numbers in the set [tex]{..., -3, -2, -1, 0, 1, 2, 3, ...}[/tex]. This means that you can add two opposite integers to get [tex]0[/tex].

For example, [tex]-3+3=0[/tex].

[tex]\huge\boxed{\text{2. True}}[/tex]

When you add a negative number to another negative number, the only thing that can happen is that the result goes down.

For example, [tex](-3)+(-2)\ =\ -3-2\ =\ -5[/tex].

[tex]\huge\boxed{\text{3. 6}}[/tex]

Let's write this as an equation, where [tex]x[/tex] represents the unknown value. [tex]-6+x=0[/tex]

We need to isolate the variable by adding [tex]6[/tex] on both sides of the equation. [tex]x=\boxed{6}[/tex]

Answer:

1) false example -1+1=0

2) true

3) 6

Final answer:

Upon examining the prices of the three cars and calculating the potential original price before rounding, we find that all three cars could have a maximum price change of £49 when rounded to the nearest £100. Therefore, all cars have the same greatest potential change in price.

Explanation:

To determine which car's price changes by the greatest amount when rounded to the nearest £100, we need to consider the possible original prices before rounding. The original price could be up to £49 above or £50 below the rounded price, as values are rounded up when they reach the halfway point (£50).

Car A

Price: £12,380. Possible price range before rounding: £12,350 to £12,429.

Car B

Price: £16,760. Possible price range before rounding: £16,750 to £16,809.

Car C

Price: £14,580. Possible price range before rounding: £14,550 to £14,629.

Now, we must calculate the maximum changes in price. The greatest amount of change occurs when the original price is at the extreme end of the range.

With each car having a possible maximum change of £49, it means that all cars could potentially have the same greatest amount of change.

Answer: S+8

Step-by-step explanation:

The score increased by 8

Let S represent the score

Increased means additional

Hence the equation is

S+8

Algebraic expression:

S = Score

S+8

Increased means add 8. Then, add 8 to the score which is "S" S would be the more common variable in which you will use here.

Answer:

The given equation not represent a proportional relationship

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem we have

[tex]y=\frac{2}{5}x-4[/tex]

This line not passes through the origin

Verify

For x=0

[tex]y=\frac{2}{5}(0)-4=-4[/tex]

therefore

The given equation not represent a proportional relationship

Each of Tasha's friends receives one-quarter (¼) of the whole snack after she eats half and divides the remainder equally between them.

To determine what portion of the whole snack each of Tasha's two best friends gets, let's first understand the portions.

Tasha eats half of the snack, leaving the other half to be shared equally between her two friends.

Since there are two friends, the remaining half is divided into two equal parts.

Mathematically, when the remaining half (½) of the snack is divided equally among two people, this half is further divided by 2, which is the same as multiplying by ½ (since dividing by a number is the same as multiplying by its reciprocal).

So, the calculation would be ½ (remaining portion) × ½ (each friend's share) = ¼.

Therefore, each of Tasha's friends gets one-quarter (¼) of the whole snack.

We can visualize this through a drawing not included here, but imagine a circle (representing the snack) divided into 4 equal parts. Tasha eats 2 parts (half), and each friend gets 1 part (one-quarter).

The portion of the whole snack each friend gets is 1/4

What portion of the whole snack does each friend get?

From the question, we have the following parameters that can be used in our computation:

Proportion eaten = 1/2

Proportion to friends = 1/2

There are  2 friends

So, the portion of the whole snack each friend gets is

Each friend = 1/2 ÷ 2

Rewrite as

Each friend = 1/2 * 1/2

Evaluate

Each friend = 1/4

Hence, the portion of the whole snack each friend gets is 1/4

Answer:

w = -12 or w = 12

-----------------------------------------------

Explanation:

The lines on each side of the w stands for "absolute value". This means that whatever number is inside the two lines is positive regarding its sign.

|12| = 12

|-12| = 12

Since the equation has the negative symbol outside the two lines, it means that the absolute value will remain negative.

Move 5 units left and 4 units up

Final answer:

To plot the point (-5, 4) from the origin, move 5 units to the left and 4 units up in a standard Cartesian coordinate system.

Explanation:

To plot the point (-5, 4) starting from the origin in a standard Cartesian coordinate system, you would need to move 5 units left and 4 units up. This is because the x-coordinate is negative, indicating a movement to the left of the origin, and the y-coordinate is positive, indicating a movement above the origin.

The correct steps are as follows:

This method adheres to the standard convention that in an xy-coordinate system, right and up are positive directions, while left and down are negative.

Answer:

y = 0.5x

Step-by-step explanation:

x = 1; y = 0.5; 0,5 is [tex]\frac{1}{2}[/tex] of 1

1 * 0.5 would equal 0.5

So, y = 0.5x

The simplified equation from the given 3x + 9 + 4x + x = _x + _ is 8x + 9 = _x + _. This equation cannot be solved further without the values for the variables represented by the underscores.

The first step to solving the equation is to simplify it. Your original equation is 3x + 9 + 4x + x = _x + _. When we simplify the left side of the equation by combining like terms we get 8x + 9 = _x + _. However, the variables in the blanks on the right side of equation are unknown, so we can't solve it fully. But now you have a simpler equation to work with, and if you receive any additional information, you can substitute those values into your simplified equation.

Answer:

x = 8

Step-by-step explanation:

First distribute the -2 to (x - 4), -2 × x is -2x and -2 × -4 is 8. The equation should now look like this, -2x + 8 = -8. Then subtract the positive 8 from both sides, giving you, -2x = -16. Then divide both sides by -2 and you should get 8 as your answer.

Answer: x=8

Step-by-step explanation:

-2(x-4)=-8

divide both sides

The total cost Abe needs to pay is the cost of one loaf, which is $2.50. Hence, the correct answer is $2.50.

Let's solve this question step by step:
Step 1: We know Abe has a coupon that allows him to buy one loaf and get the second free.
Step 2: The cost of a single loaf of bread is given as $2.50.
Step 3: As per the coupon, if Abe buys two loaves of bread, he is only required to pay for one. This means he needs to pay for one loaf only.
Step 4: Therefore, the total cost Abe needs to pay is the cost of one loaf, which is $2.50.
Hence, the correct answer is $2.50.

25/40

5/8

Answer:

there are many possible answers, but some samples are 625/1000, 125/200, 25/40, and 5/8.

Step-by-step explanation:

I just turned the decimal into a fraction using a simple method where, say, if the decimal went to the thousandths place value, like this one does, we put the decimal over 1000. If the number goes to the hundredths place, we put it over 100, etc. Then I simplified it a few times (by dividing both the numerator and denominator by 5) to get some more equivalent fractions (although you could multiply upwards and get fractions like 3125/5000 which would still be equivalent because I multiplied both the numerator and denominator, though that's besides the point) and ended up with the fully simplified fraction of 5/8.

Answer:

The rocket will take 6.49 seconds to fall back to the ground

Step-by-step explanation:

* Lets explain how to solve the problem

- A rock is thrown upward from the top of  a 25 foot tower with an initial

 upward  velocity of 100 ft/sec

- That means at t = 0 the height of the rock is 25 feet above the ground

- A function of time can  be modeled by the equation:

 h(t) =  - 16t² + 100t + 25, where h is the height of the rocket from the

 ground at time t

∵ h(t) = -16t² + 100t + 25

- The height of the rocket is 25 feet above the ground when it

  is thrown up

∴ h(t) = 25 at t = 0 ⇒ initial position of the rocket

- The height of the rocket when hits the ground is zero

∴ h(t) = 0 when the rocket hits the ground ⇒ final position of it

- We need to find the time that the rocket takes to fall back to

 the ground

∵ h(t) = 0

∵ h(t) = -16t² + 100t + 25

∴ -16t² + 100t + 25 = 0

- Lets solve it to find the value of t

∵ -16t² + 100t + 25 = 0

- Multiply both sides by -1 to make the coefficient of t² positive

∴ 16t² - 100t - 25 = 0

- Use your calculator to find the values of t

∴ t = 6.49 sec and t = -0.24 sec

∵ We will reject the value of t = -0.24, because time can not be

   negative value

∴ The rocket will take 6.49 seconds to fall back to the ground

Answer:

y = (8/5)x + 15

Step-by-step explanation:

First change the equation to standard form (y=mx+b)

5x + 8y = 16

8y = 16 - 5x

y = - (5/8)x + (16/8)

y = - (5/8)x + 2

Perpendicular Lines have the inverse opposite sign of slope

[For example: inverse opposite sign of 2 is - (1/2)]

Original equation slope (m) : - (5/8)

2nd Equation (m) : 8/5

After finding the slope, plug in the slope and points the standard form equation (y=mx+b)

Point: (-5,7)     x : -5     y : 7

Slope (m) : 8/5

y = m x + b

7 = (8/5) (-5) + b

'b' is the y-intercept and the last thing to solve for the equation

7 = - 8 + b

15 = b

Now, put the slope (m) and y-intercept (b) back into the equation

y = (8/5)x + 15
