What is the function rule for the line?

Salsk061 [2.6K]

Answer:

y =2/3x -2

Step-by-step explanation:

The y intercept is -2

The slope is

m = (y2-y1)/ (x2-x1)

Using the points (0,-2) and (3,0)

m = ( 0 - -2)/(3 -0)

= (0+2)/(3-0)

= 2/3

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y =2/3x -2

Use completing the square to solve the equation x^2+16x=-44.

Sidana [21]

Step-by-step explanation:

our equation is x²+16x = -44

x²+16x= -44
x² is the first term so weill have in the middle 2*x* a number
x²+2*x*8 = -44
the third term is 8² wich is 64 so we will add it in both sides
x²+2*x*8+64 = -44+64
(x+8)² = 20

Now that we have completed the perfect square let's solve the equation

(x+8)² = 20
x+8 = $\sqrt{20}$ or x+8= - $\sqrt{20}$
x = -8+ $\sqrt{20}$ or x = -8- $\sqrt{20}$

so the first answer is the correct one

64; 8 +/- $\sqrt{20}$

In this figure, sin(a) = 23

WITCHER [35]

$a$ and $b$ are complementary, or $b=\dfrac\pi2-a$ . So

$\cos b=\cos\left(\dfrac\pi2-a\right)=\sin a$

and so $\cos b=\dfrac23$ .

Find the value of x.

PIT_PIT [208]

Answer:

Step-by-step explanation:

180 = 7x +2 + 7x + 2 + 180 - (17x -23)

180 = 14x +4 + 180 -17x +23

180 = -3x +207

3x = 27

x = 9
