Two quantities are proportional if their ___ are equal.
A) numerator
B) denominators
C) cross products
Answer:
C) cross products
Step-by-step explanation:
Let's say you were solving [tex]\frac{1}{2}=\frac{x}{4}[/tex] for example. You would need to use cross products to simplify the problem. Here, the left side would be 1*4, and the right side would be 2*x, giving you [tex]4=2x[/tex], thus, leading to the solution [tex]x=2[/tex]. We can see clearly that the cross products would thus need to be equal to each other.

solve for X: -4x - 4 = -4(x+2)
Step-by-step explanation:
X= -4x-4=-4(x+2)
X=-4x-4=-4x-8
X=-4x+4x=-8+4
X=-4
Answer:
so there is no x but it looks like it is undefined
Step-by-step explanation:
-4x - 4 = -4(x+2) 1. multiply -4 with x and 2
-4x - 4 = -4x - 8 2. + 4 on both sides
-4x = -4x - 4 3. +4x on both sides

What fraction is 3 hours of 30 minutes
Answer:
7/2
Step-by-step explanation:
3 hours and 30 minutes = 7/2 in improper fraction
1 hour = 60 minutes
30 minutes = 30 minutes * 1 hour/60 minutes =30/60 = 1/2 hour
3 hours and 30 minutes:
= 3 hours + 1/2 hour
= 3 1/2 hours
= [(2 * 3)+1]/2

write y=x^2-6x+17 in vertex form. step by step
Step-by-step explanation:
the general vertex form is
y = a(x - h)² + k
with (h, k) being the vertex.
after doing all the multiplications we get
y = a(x² - 2hx + h²) + k = ax² - 2ahx + ah² + k
our original equation is
y = x² - 6x + 17
and now we simply compare the cording parts :
ax² = x²
a = 1
-2ahx = -2hx = -6x
-2h = -6
h = -6/-2 = 3
ah² + k = 17
3² + k = 17
9 + k = 17
k = 8
so the vertex form is
y = (x - 3)² + 8

The sun came out and the temperature quickly rose 18 degrees. the a thunderstorm hits and the temperature drops 6 degrees. the sun comes back out the temperature raises 12 degrees. the temperature is now 94 degrees. what was the starting temperature?
By solving a linear equation we will see that the initial temperature was 66 degrees.
What was the initial temperature?
Let's define T as the initial temperature.
First, it increases by 18 F, then it decreases 6 F, and finally, it increases another 12 F, such that the end temperature is 94F.
Then we can write:
T + 18F - 6F + 12F = 94F
Now we can solve that linear equation to find T.
T = 94F - 18F + 6F - 12 F = 66 F
In this way, we conclude that the initial temperature was 66 degrees.

A triangle has one side that is 4 centimeters long and
one that is 9 centimeters long.
The third side is a whole number of centimeters.
What is the LONGEST possible third side?
( these are the incorrect answers
35 and 9 )
we have three sides, let's look at the two smaller sides first.
check the picture below atop
if we move the sides closer and ever closer to each other, to the extent that one is right on top of the other, what is the length of the red side? Well, assuming the two smaller sides are one pancaked on top of the other, the red side will be as long as 9 - 4 = 5. However, the sides can't be on top of each other, because if that's so, we have a flat-line, and thus we wouldn't have a triangle. So whatever the third side may be, it must be greater than 5.
check the picture below at the bottom
Now, if we move the sides away from each other, farther and farther to the extent that one is parallel to the other, then the third side will just be as long as 4 + 9 = 13. However, we can't do that, because if that were to happen, we again will have a flat-line and not a triangle. So whatever the third side may be, it must be less than 13.
