D, they add up to 90 degrees so they are complementary

I would say complementary because it is 90 degrees. Fun fact: out of a/90 or b/90, whatever the answer is for one of the angles, the other angle will be the degree of that angle subtracted by 90

Plz helppp meee wallah I swear to god I will mark you as a brainliest and I will give you 20

Answer:

Step-by-step explanation:

Equation for the linear function has been given as,

y = 26 - 4x

For x = 1,

y = 26 - 4(1)

= 26 - 4

= 22

For x = 2,

y = 26 - 4(2)

= 26 - 8

= 18

For x = 3,

y = 26 - 4(3)

= 26 - 12

= 14

For x = 6,

y = 26 - 4(6)

= 26 - 24

= 2

Therefore, table for the function will be,

x y

1 22

2 18

3 14

Let f(x) = -2x -2. The graph of g(x) = f(x) + k is shown below. Identify the value of k.

AveGali [126]

k should be 1, Check by calculating the x values for f(x) and confronting them with g(x)

Find the equation of the tangent of x^2- xy + y^2 =7 at (-1, 2)

Citrus2011 [14]

Answer:

It is 3y = 4x + 10

Step-by-step explanation:

Let's first get the slope of the curve.

[ slope is the derivative of the equation ]

${x}^{2} - xy + {y}^{2} = 7$

introduce dy/dx :

$\frac{d}{dx} ( {x}^{2} - xy + {y}^{2} ) = \frac{d}{dx} (7) \\ \\ 2x - (y + \frac{dy}{dx} ) + 2y \frac{dy}{dx} = 0$

make dy/dx the subject:

$2x - y - \frac{dy}{dx} + 2y \frac{dy}{dx} = 0 \\ \\ 2y \frac{dy}{dx} - \frac{dy}{dx} = y - 2x \\ \\ \frac{dy}{dx} (2y - 1) = y - 2x \\ \\ \frac{dy}{dx} = \frac{y - 2x}{2y - 1}$
