Answer:

Step-by-step explanation:

Simplify the left side:

11-6 = 5

Call the right side unknown, x:

Giving us 10 - x

So we have 5 = 10 - x

Now subtract 10 from both sides:

-5 = - x

Now divide both sides by -1

5 = x

Find the equation of the circle with center (4,5) which passes through the y-intercept of the line 5x-2y+6=0​
Elena-2011 [213]

Answer:

(x-4)^2 + (y-5)^2 = 20

Step-by-step explanation:

Rearrange the line equation of 5x - 2y + 6 = 0

So y = 5/2x +3

The y-intercept of the line equation is 3 as when x=0, y=3.

We know the Circle has the formula (x-4)^2 + (y-5)^2 = ?^2 from the question but with the intercept, we can find the entire equation as the y-intercept is (0,3) so we can substitute it into the equation to find the full equations so:

(0-4)^2 + (3-5)^2 = ?^2

This simplifies to:

(-4)^2 +(-2)^2 = ?^2

16 + 4 = 20 = ?^2

The answer is 20 so the equation of the circle is (x-4)^2 + (y-5)^2 = 20

Given the function f(x)=2x-1<br> Evaluate: <br>a) 2f(x) <br> b) f(2x)​
Dmitrij [34]

Answer:

a) 2f(x) = 4x - 2

b) f(2x) = 4x - 1

Explanation:

Given function:

  • f(x) = 2x - 1

a) 2f(x)

2f(x) = 2(2x - 1)

       = 4x - 2

b) f(2x)

f(2x) = 2(2x) - 1

       = 4x - 1
