Sub x= 0.3
5(0.3) + 2y = 20
2y =20-1.5
Y= 9.25
Ans= 9.25
1/21x = 1/7
x = 1/7 * 21
x = 21/7
x = 3 <===
7.96/2 = 3.98 <==
" at most 20 " = number line graph with closed circle on 20 shaded to left
Answer:
as x→∞, y→∞
as x→-∞, y→∞
Step-by-step explanation:
To tell what the end-behavior is, look at the x with highest exponent value in the function.
f(x) = 4x⁴ - 3x²
The highest power is x⁴.
Our highest exponent value is 4.
If the highest power is an even number, the end behavior is:
as x→∞, y→∞
as x→-∞, y→∞
this is always true. It's part of the rule for end-behavior.
The end behavior graph for an even power will look like the graph for x².
This is also always true. It will always look like this if the highest power is an even number.
Answer:
Yes. A propotion is to check if two things are equivelent. The ratios 4:18 and 2:9 are equivelent.
Determine the number of possible positive and negative real roots of the equation:
x - 4x + 5x² + 9x² + 2x 8
a 2 or 0 negative roots; 3 or 1 positive roots
b. 5, 3, or 1 negative roots;
4, 2 or 0 positive roots
c.
d.
2 or 1 neative roots; 3 or 2 positive roots
3 or 1 negative roots; 2 or 0 positive roots
