Step-by-step explanation:
<u>Step 1: Find the constant
</u>
A constant is a number in a function that never changes. In this example: 2x^2 + 4x + 7, the constant is 7.
Therefore, the constant in 6x^3y + 7x^2 + 5x + 4
The answer is 4 beause it never changes.
Answer: 4
Answer:
18
Step-by-step explanation:
First, you would do a proportion
=
Then you would cross multiply, getting 50x=900.
After that, you would do 900/50, which is 18.
Answer:
B
Step-by-step explanation:
-5x = y - 5 (1)
-2y = -x - 21 (2)
Change x to the left hand side of equation (2)
x = 2y - 21 (3)
Multiply (1) by 2 times:
-10x = 2y - 10 (4)
Use (4) - (3)
-10x = 2y - 10
- x = 2y - 21
-11x = -10 + 21
-11 x = 11
x = -1
Apply x = -1 in (1)
-5*(-1) = y - 5
5 = y-5
y = 5+5
y = 10
So x = -1
y = 10
Hope this help you :3
25.34*1000=25340 because the decimal moves three positions to the right
