The answer is C, 40, angle c for triangle abc is 50 bc the total of it and 130 must equal 180. so if you subtract the angle you are given, 90, and the new angle, 50, from 180 (total a triangle should have) then your answer is 40.

Write an equation in slope-intercept form for the line that passes through (0,1) and (1,3)
Lana71 [14]

Answer:

y= 2x+1

Step-by-step explanation:

Points:

  • (0,1) and (1,3)

Form of the line:

  • y=mx+b, m- the slope,  b- y-intercept

Finding the slope:

  • m= (y2-y1)/(x2-x1)
  • m=(3-1)/(1-0)= 2/1= 2

Line is now:

  • y= 2x+b

Using one of the given points to find out the value of b:

  • 1=2*0+b
  • b=1

So the equation for the line is:

  • y= 2x+1

4. Jim and Kirk are playing a card game where they trade chips. At the beginning of the game, Jim has four times as many chips a
s2008m [1.1K]

Answer:

(a) j = 4k

(b) 4k - 18 = 18 + k

(c) Jim initially had 48; Kirk initially had 12

Step-by-step explanation:

Given

j = Jim

k=Krik

Solving (a): An equation for the amount they originally had.

From the question, we understand that j is 4 times as many as k.

Mathematically, this is:

j = 4 * k

j = 4k

Solving (b): Equation after Kirk wins

Initially Kirk had k.

To get the new expression, we add 18 to k.

This gives: 18 + k

In the same vein, Jim's number of chirps will reduce by 18.

Initially, Jim had j chirps (or 4k chirps)

To get the new expression, we subtract 18 from j.

This gives: j - 18

So, the equation is:

j - 18 = 18 +k

Solving (c): Number of chirps they started with.

In (b), we have:

j - 18 = 18 +k

Substitute 4k for j

4k - 18 = 18 + k

Collect Like Terms

4k - k = 18 + 18

3k = 36

Divide both sides by 3

k =12

Substitute 12 for k in j = 4k

j = 4 * 12

j = 48

Choose the statement beloe that lists the sides in order from Least to Greatest.
kolezko [41]

Option A: SU, TU, ST is the right answer

Step-by-step explanation:

In a triangle

  • The largest side and the largest angle are opposite to each other
  • The shortest side and the shortest angle are opposite to each other.

So using the above axioms we can observe the triangle.

  1. The largest angle is m∠U = 80° so the side opposite to it is the largest i.e. ST is the largest
  2. The smallest angle is m∠T = 25° so the shortest side is SU
  3. The third side will be the middle side as the angle ∠S is greater than 25° and less than 80°

So the sides in order from least to greatest are: SU, TU, ST

Hence,

Option A: SU, TU, ST is the right answer
