Let 11x + 15y + 23 = 0 be equation (1)
And 7x - 2y - 20 = 0 be equation (2)
Multiply equation (1) by 2:
22x + 30y + 46 = 0
Multiply equation (2) by 15:
105x - 30y - 300 = 0
Add equations (1) and (2):
22x + 105x + 30y - 30y + 46 - 300 = 0
127x - 254 = 0
127x = 254
x = 254/127
[x = 2]
Substitute x = 2 in equation (1) to find y:
11(2) + 15y + 23 = 0
22 + 15y + 23 = 0
15y + 45 = 0
15y = -45
y = -45/15
y = -3
Therefore, x = 2 and y = -3.
Hello,
f(x)=6x^3+18x²+12x=6x(x²+3x+2)
=6x(x²+x+2x+2)=6x((x(x+1)+2(x+1))
=6x(x+1)(x+2)
Zeros are 0,-1,-2
Answer:
B) [3, 5]
General Formulas and Concepts:
<u>Algebra I</u>
- Range is the set of y-values that are outputted by function f(x)
Step-by-step explanation:
According to the graph, the line's y-values span from 3 to 5. Since both are closed dot, they are inclusive in the range:
[3, 5] or 3 ≤ y ≤ 5
The answer is A since you just plug in -2for all the x’s
Answer:
The initial value is 1
The base, or rate of change, is 1/3
The domain is All real Numbers
