Determine if the given value makes the equation true or false. For x3 – 8 = 15, if x = 69

Answers

Answer 1

Answer:

(69)(3)−8 = 15

199≠15

False

Step-by-step explanation:

hope it helps, 69(3) is already bigger than 15, then -8 makes it 199, which is definitely not equal to 15.

Answer 2

Answer:

False

Step-by-step explanation:

69 * 3 =207

207 - 8 = 199

x3 - 8 = 199 for x = 69

Find the unit rate. Unit rate from chart

Answers

Answer:

I don't see a chart

Answer:

The unit rate is 15.

Explanation:

Time (hours)

6: $90            90/6 = 15

12: $180         180/12 = 15

18: $270        270/18 = 15

24: $ 360      360/24 = 15

You should find the unit rate by dividing y by x. I divided all of the y's by the x's and I got 15 for all of them, which means that the unit rate is 15.

The side length is 11 ft

Step-by-step explanation:

The area of a square is given by

A = s^2 where s is the side length

121 ft^2 = s^2

Step-by-step explanation:

GCF=Greatest common factor

we know that it can not be 15 due to 15 not going into 54 due 54 not ending in a 5 or 0. and we know it cannot be 9 either due to 9 not going into 30

so it is 6 because 6 goes into 30 5 times and 6 goes into 54 9 times

how do you change y – 5 = - (x – 1) into slope intercept form?

Answers

Answer:

y = -x + 6

Step-by-step explanation:

Slope intercept form is y = mx + b.

So distribute the negative sign on the right side to get:

y - 5 = -x +1

Then  add the 5 on the left side to both of the sides to get y alone, then you will get:

y = -x +6

That is in slope intercept form.

explain why the product of two negative integers is not negative. Use (-1) ·(-1)as an example

Answers

It will be 1, since a negative and a negative changes into a positive.

The product of two negative integers is not negative because multiplying two negative numbers always gives positive result.

What is multiplication?

Multiplication is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction, and division.

The result of a multiplication operation is called a product.

So, to prove product of two negative integers is not negative

Taking the example of (-1) ·(-1).

Now since multiplying two negative numbers always gives positive result.

Thus, (-1) ·(-1) = +1

which is not negative.

Thus, the product of two negative integers is not negative because multiplying two negative numbers always gives positive result.

Answer:

2.(b) w= 3

3. x= -3 or x= 3

Step-by-step explanation:

2.(b) Method 1:

[tex] \frac{2w - 1}{5} + w + 2 = 2w \\ \frac{2w - 1}{5} = 2w - w - 2 \\ [/tex]

Simplify:

[tex] \frac{2w - 1}{5} = w - 2[/tex]

×5 on both sides:

[tex]2w - 1 = 5(w - 2)[/tex]

Expand:

[tex]2w - 1 = 5w - 10[/tex]

Bring constants to 1 side, w terms to the other:

[tex]5w - 2w = 10 - 1[/tex]

Simplify:

[tex]3w = 9[/tex]

Divide both sides by 3:

[tex]w = 9 \div 3 \\ w = 3[/tex]

Method 2:

[tex] \frac{2w - 1}{5} + w + 2 = 2w[/tex]

Multiply by 5 throughout:

[tex]2w - 1 + 5(w + 2) = 5(2w)[/tex]

Expand:

[tex]2w - 1 + 5w + 10 = 4w[/tex]

Simplify:

[tex]7w - 9 = 4w[/tex]

+9 on both sides:

[tex]7w = 4w + 9[/tex]

-4w on both sides:

[tex]7w - 4w = 9[/tex]

Simplify:

[tex]3w = 9[/tex]

Divide by 3 on both sides:

[tex]w = 3[/tex]

3. [tex] \frac{6x - 12}{3} + 4 = \frac{18}{x} [/tex]

Multiply by 3x on both sides:

[tex] \frac{3x(6x - 12)}{3} + 3x(4) = \frac{3x(18)}{x} \\ x(6x - 12) + 12x = 3(18)[/tex]

Expand:

[tex]x(6x) - x(12) + 12x = 54 \\ 6x^{2} - 12x + 12x = 54 \\[/tex]

Simplify:

[tex]6 {x}^{2} = 54[/tex]

Divide by 6 on both sides:

[tex] {x}^{2} = 9[/tex]

-9 on both sides:

[tex] {x}^{2} - 9 = 0[/tex]

Factorise:

*Since a²-b²= (a +b)(a -b),

[tex] {x}^{2} - {3}^{2} = 0 \\ (x + 3)(x - 3) = 0[/tex]

Thus,

x +3= 0 or x -3= 0

x= -3 or x= 3

Answer:

w = 3

Step-by-step explanation:

(6x-12)/3 + 4 = 18/x

Simplify fraction

2x -4 +4 = 18/x

Combine -4+4=0 Divide by 2 to reduce

x = 9/x

Multiply both sides by x

x² = 9

x = 3, -3

Hi! (-8)(-6) can also be written as -8 × -6. Ignore the negative signs for now.

8 × 6 = 48.

When two negative numbers are multiplied together, the answer is always positive. Think of it as two negative signs (-) make a positive sign (×) when put together.
