The formula for direct variation is y = kx<span> where k </span>≠ 0
y = 9/x is an inverse relation
Answer:
1. x²-2x+15
This can't be factored, I've tried multiple ways now, but it just can't be factored.
2. y²-19y+90
Let's factor y^2−19y+90
y^2−19y+90
The middle number is -19 and the last number is 90.
Factoring means we want something like
(y+_)(y+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -19
Multiply together to get 90
Can you think of the two numbers?
Try -9 and -10:
-9+-10 = -19
-9*-10 = 90
Fill in the blanks in
(y+_)(y+_)
with -9 and -10 to get...
(y-9)(y-10)
Answer:
(y−9) (y−10)
2 ounces
using the conversion
1 pound = 16 ounces ⇒ 
= 8 ounces
Divide 8 by 4 to calculate amount for each cone
amount = 8 ÷ 4 = 2 ounces
Given:
Base length of triangle = 10 units
Height of triangle = 
units
Length of hypotenuse of triangle = 12 units
To find:
Exact value of Cos A
Steps:
The cosine of any angle is equal to the length of the adjacent side by the length of the hypotenuse side.
So,
Cos A = 
Cos A = 
Cos A = 0.833
Therefore, the exact value of cos A is 0.833.
Happy to help :)
If u need any help, feel free to ask
Vertical angles= XAW and UAY
complementary angles =XAW and XAZ
adjacent but not complementary or supplementary = XAZ and ZAY
supplementary = XAW and WAU
