Answer:

  A  1

Step-by-step explanation:

The cube containing 125 = 5³ blocks will have a edge dimension of 5 blocks. The perimeter of one square face will be 4 times the edge dimension of the face, so will be 4×5 blocks = 20 blocks.

If 20 blocks = 20 units, then the edge of one block is 1 unit. Its volume is 1 unit³, or 1.

The appropriate choice is (A) 1 unit³ for the block volume.

Given:

Twice the sum of x and 3 is decreased by 13.

To find:

The expression for the given statement.

Solution:

The sum of x and 3 is (x+3).

Twice the sum of x and 3 is two times of (x+3), i.e., 2(x+3)

Negative sign is used of decrease.

Decreased by 13 is represented by -13.

Using these representation, we get

Twice the sum of x and 3 is decreased by 13: [tex]2(x+3)-13[/tex]

Therefore, the required expression is [tex]2(x+3)-13[/tex].

Answer: Jacque sold 120 greeting cards in that week.

Step-by-step explanation:

Given : Profit per card = $ 0.35

Total profit = $42

Number of greeting cards Jacque sold = (Total profit) ÷ (Profit per card)

[tex]=\$42\div\$0.35\\\\=\dfrac{4200}{35}\\\\= 120[/tex]

Hence, Jacque sold 120 greeting cards in that week.

Answer:

a)

x      -3         -2         -1         0          1            2         3

y       0          8          6         0         -4           0        18

b)

see in the table, at x = {-3; 0; 2}, y = 0

=> x = {-3; 0; 2} is the solutions of the equation x³ + x² - 6x = 0

Step-by-step explanation:

a) 0 and 6  will be written in the given blank spaces.

b) The value of x for the given equation is 0, -3 and 2.

It is a method for finding the values of variable, by substituting the value of one variable to get the another.

To solve a polynomial equation, first write it in standard form. Once it is equal to zero, factor it and then set each variable factor equal to zero.

a). We have, an equation

[tex]y = x^{3}+x^{2} -6x[/tex]

so, at x = -3

[tex]y = -3^{3} +(-3)^{2} -6(-3)[/tex] =  -27+9+18 = 0   (substitute x = -3 in the given equation)

at x = -1

y = [tex]-1^{3} +(-1)^{2} -6(-1) = -1+1+6 = 6[/tex]

Hence, 0 and 6 will we written the blank spaces of the given table.

b). We have an equation

[tex]x^{3} +x^{2}-6x = 0[/tex]

⇒ [tex]x(x^{2} +x-6)=0[/tex]

⇒ [tex]x (x^{2} +3x-2x-6)=0[/tex]

⇒ [tex]x(x(x+3)-2(x+3))=0[/tex]

⇒ [tex]x(x+3)(x-2)=0[/tex]

⇒ [tex]x = 0,-3 and 2[/tex]

Hence, 0, -3 and 2 are the solutions of the given equation.

On Edge 2020

Answer:

t > 82

Step-by-step explanation:

Given that,

The dance committee of Pine Bluff Middle School earns $72 from a bake sale and will earn $4 for each ticket they sell to the Spring Fling dance.

The dance will cost $400.

We need to find an inequality to determine the number, t, of tickets the committee could sell to have money left over after they pay for this year's dance.

The committee earns $4 for each ticket. It means they will earn $4t.

$72 is constant as they earn it from bake sale.

The total earning must be greayer than $400.

ATQ,

4t + 72 > 400

We can solve the above inequality to find the value of t.

4t > 328

t > 82

Hence, the committee could sell more than 82 tickets to have money left over after they pay for this year's dance.

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

Explanation:

Think of x as a placeholder for a number. For me, I tend to think of it as a box. It's handy that the letter x is part of box, to help make that connection better. We have some box and inside the box goes a number.

If we multiply 5 by whatever is in the box, we can write it like [tex]5*\square[/tex]

Then let's say we fill that box with the value 7. We would then have [tex]5*\boxed{7}[/tex]

If we put 3 in the box instead we'll have [tex]5*\boxed{3}[/tex] and so on

Unfortunately the box symbol isn't something we could easily write on a keyboard, so we go with x instead to make life simpler.

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

So far we've shown that "5 times a number" turns into 5*x or just 5x.

From here we subtract off 3 to get 5x-3 as the final answer. Whatever the result of 5x is, we subtract off 3.

The answer would not be 3-5x since this means "subtract 5x from 3". The order of subtraction matters. In general, A-B is not the same as B-A.

Variation tax = 0,25

Step-by-step explanation:

Direct variation is the name we gave to the rate of change of a first degree function.

A first degree generic function is:

y = f(x) = ax + b

Now observe the question's function:

- x + 4y = -2

4y = x - 2

y = 1/4x - 2/4

y = f(x) = 0,25x - 0,5

0,25 is our constant variation, because any number that x assume will be multiplied by 0,25.

Step-by-step explanation:

So we first write the inequality 3 + 1.2c "is greater than or equal to sign" 13.5. Then we subtract 3, then divide both sides by 1.2 to isolate c. We get x "is greater than or equal to" 8.75.

The system of equations has no solution.

NO SOLUTION!

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}y=-\frac{1}{2}x+4\\ x+2y=-8\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}y+\frac{1}{2}x=4\\ 2y+x=-8\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}y+\frac{1}{2}x=4\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:2y+x=8[/tex]

[tex]\begin{bmatrix}2y+x=8\\ 2y+x=-8\end{bmatrix}[/tex]

subtracting equation 2y+x=8 from 2y+x = -8

[tex]2y+x=-8[/tex]

[tex]-[/tex]

[tex]\underline{2y+x=8}[/tex]

[tex]0=-16[/tex]

so the equations become

[tex]\begin{bmatrix}2y+x=8\\ 0=-16\end{bmatrix}[/tex]

0 = -16 is false, therefore the system of equations has no solution.

Answer:

No

Step-by-step explanation:

We can check with the Pythagorean Theorem.

a^2 + b^2 = c^2

  a and b are always the smaller sides, the legs

  c is the longer side, the hypotenuse

3^2 + 3^2 >  6^2

9 + 9 > 36

18 < 36

18 is not greater than 36, therefore this triangle can not have the side lengths 3, 3, and 6.

Answer:

B. -2

Step-by-step explanation:

A relation that is not a function would have one x-value having two different corresponding y-values.

If we choose -2 to represent b I the relation, the relation would not be a function. This is because, we there would be two different y-values, 8 and 1, that are assigned to one x-value, which is -2 ==> (-2, 8) and (-2, 1).
