I think it is one plus one
Answer:
57.77 °
Step-by-step explanation:
For this case we have the following trigonometric relationship:
cos (x) = 8/15
x = (8/15)
x = 57.76904736 degrees
Rounding off answer to the nearest hundredth.
y = 57.77 degrees
Portion under square root sign:
= (b^2 - 4*a*c).
Answer:
<em>y=-6</em>
Step-by-step explanation:
<u>Proportions</u>
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality.
Substituting x=-3 y=9:
9 = k(-3)
Now the relationship is:
y = -3x
For x=2
y = -3(2) = -6
