Answer:
see the explanation
Step-by-step explanation:
Let
x ----> number of tennis balls
y ----> number of tennis rackets
we know that
To find out the ratio of tennis balls to tennis rackets, divide the number of tennis ball by the number of tennis rackets
In this problem we have

see the model in the attached figure N 1
so


This is the equation of a linear direct variation
The relationship between the variables x and y is proportional
see the model in the attached figure N 2
<span>Answer:
When two angles add up to 90</span>°, it is complementary.
Linear pair<span> of angles are formed when two lines intersect.
</span><span>Vertical is each pairs of opposite angles made by two intersecting lines.
</span>Adjacent angles are angles that are next to or neighboring each other.
Hope this helps!
Step-by-step explanation:
√9x2√18y2. √9=3. √x2=x. √18=√9×2=3√2. √y2=y. Therefore √9x2√18y2=3x3√2y = x√2y.
Answer:
7 units
Step-by-step explanation:
To find the distance between a pair of points, use the distance formula,
. Substitute the x and y values of (5,5) and (5, -2) into the formula and simplify:

So, the answer is 7 units.
