Answer:

See below

Step-by-step explanation:

11 box 1: 12

11 box 2: 101

12 box 1: 80

12 box 2: 80

12 box 3: 80

13 box 1: 16

13 box 2: 16

13 box 3: 76

20 = y + 12

20 - 12 = y + 12 - 12

8 = y

x + 2 = 19

x + 2 - 2 = 19 - 2

x = 17

z - 313 = 176

z - 313 + 313 = 176 + 313

z = 489

20 = y + 12

20 - 12 = y + 12 - 12

8 = y

x + 2 = 19

x + 2 - 2 = 19 - 2

x = 17

z - 313 = 176

z - 313 + 313 = 176 + 313

z = 489

Write the equation in slope intercept form of the line that passes through the point (1,-3) and a slope of -2

Alborosie

Answer:y=-2x-1

Step-by-step explanation:

(1,-3) and a slope of -2

Use Formula

Y= mx +b to find b. By using the slope and point given .

M is slope

Y is -3

X Is 1

Y=mx+b

-3= -2(1)+b

-3= -2+b

-3+2=b

-1=b

Now create the equation by inputting the slope they gave you which is -2 and answer we solved for b which is -1 .

Y= -2x-1

Find x.______________a0

velikii [3]

Answer:

$x=4$

Step-by-step explanation:

Before we find x, we need to set up this triangle a little more. We need to find the triangle's altitude before we can solve for x. We will use the heartbeat method to find the altitude.

Let altitude = y; solve for y:

$\frac{2}{y}=\frac{y}{6}$

$y^2=12$

$y=\sqrt{12}$

$y=2\sqrt{3}$

Now that we know the altitude, we can use the Pythagorean Theorem to find the hypotenuse (x).

$a^2+b^2=c^2$

$2^2+(2\sqrt{3})^2=c^2$

$4+12=c^2$

$c^2=16$

$c=4$

Since c and x are the same; c is just the hypotenuse in the Pythagorean Theorem.

$x=4$
