Answer: 18

Step-by-step explanation:

X-1=2

X=3

2(3)^2

2(9)

18

Value of an algebraic expression depends on the values of its variables usually. The value of [tex]2x^2[/tex] for given condition is obtained to be 18

You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.

For the given case, we are given that [tex]x - 1 =2[/tex]

By this, we can get the value of the variable 'x' as:

[tex]x - 1 = 2\\\text{Adding 1 on both the sides, we get}\\x = 3[/tex]

Now, putting 3, in place of x, in expression [tex]2x^2[/tex], we get:

[tex]2x^2 = 2 \times (3^2) = 2 \times 9 = 18\\[/tex]

( sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together, thus, [tex]2x^2 = 2 \times x^2[/tex])

Thus, the value of [tex]2x^2[/tex] for given condition is obtained to be 18

Answer:

The top shelf is 5 feet, the middle shelf is 5.5 feet and the bottom shelf is 9.5 feet

Step-by-step explanation:

Let t= length of the top shelf, m = length of middle shelf and b = length of bottom shelf.

Therefore:

t = m - 1/2; m = t  + 1/2

Also, b = 2t - 1/2

The total of the three shelves is 20 feet, therefore:

t + m + b = 20

Substituting:

t + t + 1/2 + 2t - 1/2 = 20

4t = 20

t = 20/4

t = 5 feet

m = t + 1/2 = 5 + 1/2 = 5.5 feet

b = 2t - 1/2 = 2(5) - 1/2 = 9.5 feet

The top shelf is 5 feet, the middle shelf is 5.5 feet and the bottom shelf is 9.5 feet

Answer:

b.) 3p=6 is not equivalent

Step-by-step explanation:

If you solve and do the same thing on both sides you will get every other solution except b.

Answer:

The correct answer is b) 3p = 6

Step-by-step explanation:

First, we need to find p:

3p - 2 = 6p + 4

-2 = 3p + 4

-6 = 3p

-2 = p

Now, we just need to plug p's value into each question:

a) 3p = 6p + 6

3(-2) = 6(-2) + 6

-6 = -12 + 6

-6 = -6

Since -6 = -6, a is not the correct answer.

b) 3p = 6

3(-2) = 6

-6 = 6

Since -6 ≠ 6, b is the correct answer.

c) -6 = 3p

-6 = 3(-2)

-6 = -6

Since -6 = -6, c is not the correct answer.

d) -3p - 2 = 4

-3(-2) - 2 = 4

6 - 2 = 4

4 = 4

Since 4 = 4, d is not the correct answer.

Therefore, b is the correct answer.

Answer:

The solution lies at approximately (4.25,6.5).

Step-by-step explanation:

The estimation is moderately close for both of the equalizations. For the very first equation, the calculation appears in an amount that is barely 0.2125 units distant from the permanent. For the second equation, the calculation appears in an amount that is barely 0.25 units apart from the permanent.

Answer:

Wrong. If the line segment AB= 10, then the measure of AC= 10 as well. It's a right triangle. All the sides are the same.

Step-by-step explanation:

Answer: Not correct.  The tic marks on the angles mean that this is an equilateral triangle  

All the line segments are equal. If a length is given for one side of the triangle, the others are the same

All the angles are equal. The total of all the angles is 180. to find any one of them divide 180 ÷ 3

Answer:

0.2839

Step-by-step explanation:

Can you tell me what part you are stuck on?

Answer:

0.2839

Step-by-step explanation:

-First, move the decimal over 4 places to the right to make 0.0167 into a whole number, which will turn into 167.

-Now, multiply 17 times 167 to get 2839.

-Finally, since the decimal from 0.0167 was moved 4 places to the right, it needs to be moved back 4 places to the left. Once it was moved back 4 places to the left, the answer should now be 0.2839

Hope this helps! :)

Answer:

The equation of a parallel to the given line that goes through the given point (2, 4) is:

[tex]y=8x-12[/tex]

Step-by-step explanation:

Given the equation

[tex]y=8x+3[/tex]

comparing the equation with the slope-intercept form

[tex]y=mx+b[/tex]

Here,

so the slope of the line is m = 8.

We know that the slopes of parallel lines are equal.

so, the slope of the perpendicular line will be = 8

Therefore, the equation of a parallel to the given line that goes through the given point (2, 4) is:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-4 = 8 (x-2)[/tex]

[tex]y-4 = 8x-16[/tex]

[tex]y = 8x-16+4[/tex]

[tex]y=8x-12[/tex]

Answer:

The given statement is true.

Step-by-step explanation:

Given function is:

[tex]P(x) = x^4 - 2x^3 - x+2[/tex]

And the given point is:

(1,0)

In an ordered pair, the first element is the input and second is the output. If we plug in the input to the function and get the respective output then the point lies on the graph of function.

For (1,0) we will put x = 1 in function and check whether we get 0 as output

[tex]P(x) = (1)^4 - 2(1)^3 - 1+2\\= 1-2(1)-1+2\\= 1-2-1+2\\=0[/tex]

Hence,

The given statement is true.
