Answer:
C
Step-by-step explanation:
The equation of quantities in direct variation is
y = kx ← k is the constant of variation
The only equation in this form is 4y = - 12x, that is
4y = - 12x ( divide both sides by 4 )
y = - 3x ← in form representing direct variation with k = - 3 → C
6t^-7 * 3t^5 = 1/6t^7 * 3t^5
Hi there!
We have:
-3 - x = -2w + 4v
Solve for x
Start by adding 3 to both sides
-3 - x + 3 = -2w + 4v + 3
-x = -2w + 4v + 3
Remember that we cannot leave the x with a negative sign.
There are two ways to remove the negative sign.
1) We can divide both sides by -1
2) We can multiply both sides by -1
In this, I am going to multiply both sides by -1
-x * -1 = (-2w + 4v + 3)(-1)
x = 2w - 4v - 3
I hope this helps.
Please let me know if you have questions about the answer.
Thanks!
5. We add all the freshman, 92 + 86 = 178.
6. We add all the sophomores surveyed, 116 + 52 = 168,
7. We add the numbers under the "yes" category, 92 + 116, which is 208.
8. We add the numbers under the "no" category, 86 + 52, which is 138.
11. A marginal frequency is the total of freshman, 222, and the total sophomores are 192. The marginal frequency of freshman are greater than that of the sophomores.
(there is no #9, #10, or a table for #12)
The ANSWER is 63
because 90+27=117
180-117=63
