Answer:

y = -7/6 x + 55/6

Step-by-step explanation:

(1,8) and (7,1)

slope =(8-1)/(1-7) = 7/-6 = -7/6

Equation

y - 1 = -7/6(x - 7)

y - 1 = -7/6 x + 49/6

y = -7/6 x + 49/6 + 6/6

y = -7/6 x + 55/6

Lostsunrise [7]

Answer:

The first piece is 6 inches, the second piece is 24 inches, and the third piece is 30 inches

Step-by-step explanation:

Since the second piece is 4 times longer than the first one, it will be represented by 4x.

The third piece is 5 times as long as the first one, so it will be represented by 5x.

Create an equation adding up the 3 x values up to 60:

x + 4x + 5x = 60

Add like terms and solve for x:

10x = 60

x = 6

So, the first piece is 6 inches.

Then, plug in 6 for x to find the lengths of the second and third pieces.

4(6)

= 24

The second piece is 24 inches

5(6)

= 30

The third piece is 30 inches

So, the first piece is 6 inches, the second piece is 24 inches, and the third piece is 30 inches

Find the missing angle

inna [77]

THEOREM:

Angle sum property —: The sum of interior angles of a triangle is 180°.

ANSWER:

Let the missing angle be x.

By angle sum property,

∠x + 20° + 80° = 180°
∠x + 100 = 180°
∠x = 180° – 100°
∠x = 80°

So, <u>Correct choice</u> - [C] 80°.
