Equation of the line:
y = -0.4x + 1.6
or
y =
- 2 x
5
+ 8
5
When x=0, y = 1.6
When y=0, x = 4

Answer:
Points A, C, and D are coplanar, and Point B is noncollinear.
Step-by-step explanation:
Answer:
cos(∅) = 3/5
Step-by-step explanation:
cos(∅) = adjacent/hypotenuse
We don't know what the hypotenuse is so we gotta use Pythagorean theorem to find it.
a² + b² = c²
4² + 3² = c²
√(4² + 3²) = c
c = 5 , this is our hypotenus
cos(∅) = adjacent/hypotenuse
cos(∅) = 3/5
X = amount of seeds.
y = amount of dried fruits.
we know the snack mix contains both, and we know is 10oz, thus
x + y = 10, whatever ounces "x" and "y" are.
how much is it for "x" ounces if each one costs $1.5? well is just 1.5*x or
1.5x.
how much is it for "y" ounces if each one costs $2.5? well is just 2.5*x or
2.5x.
the mix contains 10 ounces, each of which costs $2.2 each, how much will it be then for 10 oz? well, is just 10 * 2.2, or $22.
since the whole 10 oz snack mix costs 22 bucks, then
1.5x + 2.5y = 22.

how many ounces of dried fruit is there anyway? well, y = 10 - x.
