How is this a non proportional relationship y=2x 4?
saveliy_v [14]
Y=2x +4 is non proportional because b does not equal 0
The b in the equation is 4
As long as the y intercept is not more or less than 0, than it will be proportional

What is the slop of a line that is perpendicular to the line y= 1/6 x + 4?
Kay [80]
Y = 1/6x + 4....the slope here is 1/6. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign.
So the slope of a perpendicular line will be -6/1 or just -6...see how I flipped the slope and changed the sign.

Swanson plans to attempt to swim across the lake from point A to point B as shown below. To determine how far he will have to sw
Ipatiy [6.2K]

Answer:

2.38 miles

Step-by-step explanation:

From Given diagram:

In ΔABC,

AC=2.5 miles

BC= 3.7 miles

∠BCA= 39.4°

Now as we have two sides and an angle, using law of cosines to find the third side:

c= √(a^2+b^2-2abcosα

AB=√(AC)^2 + (BC)^2 - 2(AC)(BC)cosα

    =√(2.5)^2 + (3.7)^2 - 2(2.5)(3.7)cos(39.4°)

    =√(2.5)^2 + (3.7)^2 - 2(2.5)(3.7)(0.77)

   =√(5.695)

     = 2.38 !

Simplify the expression (7x+1/2)+(6x-9 1/2)
monitta
To make this easier to read, I'll be substituting 1/2 for .5; they mean the same thing, but it's less confusing to type it in its decimal form.
7x + .5 + 6x - 9.5
Combine like terms (x's can be added together, and so can reg. numbers)
(7x + 6x) + (.5 - 9.5)
13x - 9
