mark as brainliest pls
Step-by-step explanation:
I count four 6s, four 4s and three b.
so, we have
6⁴×4⁴×b³ or (using the same symbols as above)
6⁴.4⁴.b³
<span>the sum of the first and three times the second is 54.
x + 3y = 54
3y = 54 - x
y= 54 /3 - x / 3 = 18 -x /3
</span>xy = x (18 -x /3) = 18x - x^2 / 3 = - 1/3 x ^ 2 + 18 x
<span>
</span><span>since a<0, it is concave downward, and the vertex is the maximum value. That vertex occurs at x= - b /2a = (-18) / (-2/3) = 12
</span>
<span>The first number is x=12.
The second is y = </span><span>18 -x /3 = 18- 12/ 3 = 18 - 4 = 14 </span>
One way to test if a graph is a function or not is by doing a <u>vertical line test</u>.
<em>The </em><u><em>vertical line test</em></u><em> is tested by testing if any vertical line is drawn would intersect the curve more than once. If there is any such line, the graph does not represent a function, if there isn't any such line, the graph is a function.</em>
Hope that helps!
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.
