Mathematics
1 answer:
kvasek [131]3 years ago
8 0

Answer:

y=\frac{x}{2} +5

Step-by-step explanation:

y=2x-10\\x=2y-10\\x+10=2y\\\frac{x+10}{2} =y\\y=\frac{x}{2} +5

First, we swap x and y. Then, we solve for y in the new equation.

Applied to the graph of y= 1/x
Bess [88]

Answer:

y = -3/(x-4) - 2

Step-by-step explanation:

3*y(x) vertically stretches <em>y</em> by a factor 3

-y(x) reflects <em>y</em> over x-axis

y(x-4) translates <em>y</em> 4 units to the right

y(x) - 2 translates <em>y</em> 2 units down

Applied the transformations we get:

y(x) = 1/x → 3/x → -3/x → -3/(x-4) → -3/(x-4) - 2

What is the value of x?
Andrei [34K]

Answer:

x=2

Step-by-step explanation:

We will use the secant-secant Formula:

(whole secant) x (external part) =         (whole secant) x (external part)

(1+x+4) * (x+4) = (11+x+1) * (x+1)

Combine like terms

(x+5) (x+4) = (x+12) (x+1)

FOIL

x^2 + 4x+5x + 20 = x^2 +  x+ 12x + 12

Combine like terms

x^2 + 9 x + 20 = x^2 + 13 x + 12

Bring everything to the left

x^2 + 9 x + 20- (x^2 + 13 x + 12) = x^2 + 13 x + 12-( x^2 + 13 x + 12)

x^2 + 9 x + 20- (x^2 + 13 x + 12) =0

Distribute the minus sign

x^2 + 9 x + 20- x^2 - 13 x - 12 =0

Combine like terms

-4x +8 = 0

Subtract 8 from each side

-4x+8-8=0-8

-4x=-8

Divide each side by -4

-4x/-4 = -8/-4

x=2

Find the slope-intercept form of the line passing through the point (-4, -9) and parallel to the line y= -5x +4
Damm [24]
It’s C. The slope needs to be the same. -5 makes it go down 5, right 1, and 5 makes it go up 5, right 1.
