What is x in this equation -3x+7 = 1

Answers

Answer 1
the answer is x=2 because you have to subtract 7 on both sides so you get -3x=-6 then to get x alone you have to divide by -3 because a negative and a negative divided together makes a positive so you divide -3 to both sides and you get x=2

What is trigonometry?

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

The trigonometric expression is given below.

[tex]\cos (\dfrac{\pi}{2} + r)[/tex]

We know that the formula

[tex]\cos (\dfrac{\pi}{2} + r) = -\sin r[/tex]

Thus, the cos (π/2 + r) is equivalent to the negative of sin r.

The square below has the given side lengths. x is positive

Answers

Answer:

Value of X: X=2

Length of One Side: 31

Area: 961u^2

Perimeter: perimeter = 124

Step-by-step explanation:

Set the sides equal to each other, simplify and then use quadratic equation. One result is positive and the other is negative, shape's sides have to be positive so use the positive value for X.

Answer:

See below, please

Step-by-step explanation:

This square

[tex]3 {x}^{2} + 6x + 7 = 2 {x}^{2} - 2x + 27[/tex]

[tex](3 {x}^{2} - 2 {x}^{2} ) + (6x + 2x) + (7 - 27) = 0[/tex]

[tex] {x}^{2} + 8x - 20 = 0[/tex]

[tex](x + 10) \times (x - 2) = 0[/tex]

Hence,

[tex]x1 = 2[/tex]

[tex]x2 = - 10[/tex]

Because x is positive, So,

[tex]x = 2[/tex]

Then we know

The length of one of the sides

[tex] = 3 {x}^{2} + 6x + 7 = (3 \times {2}^{2}) + (6 \times 2) + 7 = (3 \times 4) + 12 + 7 = 31[/tex]

The area of the square

[tex] = {31}^{2} = 961[/tex]

The perimeter of the square

[tex] = 31 \times 4 = 124[/tex]

Evaluate the expression 2bc for b = 1.5 and c = 5.

Answers

Answer:

15

Step-by-step explanation:

To answer this, simply input your values into the equation:

Since b is given as 1.5, and c is given as 5, you put it into the calculation 2bc

so, you would do 2x1.5x5

which is equal to 15

Answer: 15

Step-by-step explanation: Multiply it. You have 2bc, b=1.5, c=5 plug those values into 2bc. You should get 2(1.5)(5) and that'll be 15.

2. Determine whether the two functions are inverses.
f (x) = 1/2 x-3
g(x)= 2x+6

please help

Answers

Answer:

The two functions are inverses.

Step-by-step explanation:

Recall what an inverse is:

When you inverse an equation, like y = 2x for example, you switch, the y and x values. So you'd now have x = 2y, then x/2 = y.

In a case like that we'd say that, y = 2x, and y = x/2 are inverses of each other.

Now looking at your question, all we'd need to do is take the inverse of 1, and see if it matches up with the other one. So pick a function. I'll choose g(x) and I'll inverse it.

[tex]g(x) = y = 2x + 6[/tex]

get rid of the g(x), as it doesn't help you anymore.

[tex]y = 2x + 6[/tex]

then, switch the x and the y.

[tex]x = 2y + 6[/tex]

then isolate for y.

[tex]x - 6 = 2y[/tex]

[tex]\frac{x-6}{2} = y[/tex]

Now let's see, does [tex]f(x) = \frac{1}{2}x - 3[/tex] equal [tex]\frac{x-6}{2}[/tex] ? Well actually yes.

We just didn't simplify all the way.

[tex]\frac{x-6}{2} = y\\[/tex]

divide each term by 2

[tex]\frac{x}{2} - 3 = y[/tex]

[tex]\frac{x}{2}[/tex] can be written as [tex]\frac{1}{2}x[/tex] so we get

[tex]\frac{1}{2}x - 3[/tex] which is equal to f(x)

Therefore the 2 functions are inverses.

Q.E.D

Ali graphs the function f(x) = –(x + 2)2 – 1 as shown.

Answers

Total surface area includes the area of the 2 bases and the area of the curve surface area this was found to be 289.064 square inches for all four mugs

Mensuration of Solids

Given Data

Radius r = 2 inchesHeight h = 3.75 inchesNumber of mugs = 4

Total surface area of cylinder = 2πr(r + h)

TSA of 1 mug = 2*3.142*2(2+3.75)

TSA of 1 mug = 12.568(5.75)

TSA of 1 mug = 72.266 square inches

if the total surface area of one mug is 72.266 square inches

hence the total surface area of 4 mugs will be
