Step-by-step explanation:
General equation for horizontal line: y = a
Since the point (5, 3) has y-value 3,
the equation of the horizontal line is y = 3.
Answer:
$8.60
Step-by-step explanation:
Let’s find the cost for each item
Apples: 2.5 x 1.30 = 3.25
Grapes: 2.5 x 1.65 = 4.125
Bananas: 2.5 x 0.49 = 1.225
Now we will add all the costs which will give use our total!
3.25 + 4.125 + 1.225 = 8.6
So the answer will be $8.60
This question is asking "Where does cosine equal
?"
Based on our unit circle values and the domain of the cos^{-1} function, we see that at 30 degrees, or
, cosine is equal to
.
Direct variation is y=kx where k is a constant
the fiest way to see if it is direct or not, is if x increases, then y increases as well,
then we see if y=kx is valid, basically if we have a constant of variation
the first one x increase and y increase
see if same constant
y=kx
-4.5=-3k
1.5=k
so
see next one
-1 and 3
-3=-1(k)
-3=-1(1.5)
-3=-1.5
false
not it
2nd is increase and y decrease, so not direct variation
3rd is x is same but y increase so nope
4th is x increase and y increase, now test the constant
-7.5=-3k
2.5=k
-1 and -2.5
-2.5=-1k
-2.5=-1(2.5)
-2.5=-2.5
true
answer is last option
