If (x - 2)² = 49 , then x could be?

Answers

Answer 1

Answer: $(x-2)^2=49\iff x-2=√(49)\ or\ x-2=-√(49)\n\nx-2=7\ or\ x-2=-7\n\nx=7+2\ or\ x=-7+2\n\nx=9\ or\ x=-5\n\nAnswer:x\in\{-5;\ 9\}$

Answer 2

Answer: (x - 2)² = 49
x² - 2x - 2x + 4 = 49
x² - 4x = 45
x² - 2x = 45 + (- 2)²
x² - 2x = 45 + 4
(x - 2)² = 49
x - 2 = 7

x = 7 + 2, x = 9
x = - 7 + 2, x = - 5

Answer: 9 or the fifth choice. x is also - 5.

Solve the equation and enter the value of x below X+40=59

Answers

Answer:

X = 19

Step-by-step explanation:

To solve the equation X + 40 = 59, we need to isolate the variable X on one side of the equation.

1. Start by subtracting 40 from both sides of the equation:

X + 40 - 40 = 59 - 40

This simplifies to:

X = 19

2. Therefore, the value of X that satisfies the equation is 19.

In summary, to solve the equation X + 40 = 59, you subtract 40 from both sides of the equation to isolate the variable X. This results in X = 19.

Answer:

sinθ = 12/15 -> 4/5

cosθ = 9/15 -> 3/5

tanθ = 12/9 -> 4/3

cscθ = 15/12 -> 5/4

secθ = 15/9 -> 5/3

cotθ = 9/12 -> 3/4

Step-by-step explanation:

The theta is where you would use to identify the numbers for the trig functions. The adjacent side is the one closest to the theta (but not the diagonal line, that is the hypotenuse), and the opposite line is the line next to the adjacent line.

For the first three trig functions, would use the method Soh Cah Toa.

Sin = opp/hypotenus, Cosine = adjacent/hypotenuse, and Tangent = opposite/adjacent. Then, there is cosecant(csc) = hyp/opp, secant = hyp/adj, and cotangent = adj/opp.

How do i figure this out?

Answers

Answer:

Slope of function A is greater than slope of function B

Step-by-step explanation:

You calculate the gradient (slope) of function B. That is, change in y divided by change in x.

Take point (0, 1) and (2, 5) from the graph of function B.

change in y = 4

change in x = 2

gradient = 2

b(x) = 2x + 1

Therefore the function B has a lesser slope than function A
