Since, in this case, we have 4 options then you just need to substitute each number.
A. y = 5/x
B. y = 14/x
C. y = 9/x
D. y = 3.5x
We know that x= 2 when y=7. So...
A. y = 5/x
7=5/2
7=2.5
This is false.
B. y = 14/x
7= 14/2
7=7
This is right, So True.
C. y = 9/x
7=9/2
7=4.5
False
D. y = 3.5x 7=3.5(2)
7=7
This one is also true.
In this case we look for definition.
he statement " <span>y </span>varies inversely as <span>x </span>means that when <span>x </span>increases, <span>y </span>decreases by the same factor. In other words, the expression <span>xy </span>is constant:
xy = k
where k is the constant of variation.
We can also express the relationship between x and y as:
y = k/x
where k is the constant of variation.
What artist is it? Native Americans used roots, berries, tree bark etc. to make pigments your paint with. They would crush and grind them into a powder. Then they could blend it with other things to make due. Early artists had to find the items to make pigments and paints.
I hope this helped. If it didn’t I’ll try to help more.
Answer:
infinitely many solutions
Step-by-step explanation:
Let's first eliminate y^2.
To accomplish this, divide the 2nd equation by 5, obtaining
y^2 = 5/2 - x^2. Now substitute this result for y in the first equation:
(-1/3)x^2 = -5/6 + (1/3)(5/2 - x^2), or
-x^2 -5 5 x^2
-------- = ------ + ------- - -------- and this simplifies to:
3 6 6 3
-x^2 x^2
------- = - ------- which is an identity and is thus always true.
3 3
Thus, any value of x will satisfy this equation; there are infinitely many solutions.
Answer:
74°
Step-by-step explanation:
Let ½(theta) = X
Tan(X) = opposite/adjacent
= 7.5/10
X = (tan^-1)(0.75)
X = 36.8698976458
Theta = 2X = 2(36.8698976458)
Theta = 73.7397952916
Nearest degree: 74°
