Answer:
Step-by-step explanation:
- 5x² - 20x + 15 = 0
- x² - 4x + 3 = 0
- x² - 4x + 4 = 1
- (x - 2)² = 1
- √(x - 2)² = √1
- x - 2 = ± 1
- x = 2 ± 1
- x = 1, x = 3
This is easy
69 because it says after two shoveling jobs he starts to get 9 pennies a job the first two jobs were only worth 3 pennies each so 3+3=6 so 6+9x7=69

Answer:
3x ≤ 12 x≤4
Step-by-step explanation:
If Antonio has only $12 to spend on the milk, then the inequality sign should be less than or equal to. Since he can not go over 12. So from this you must figure out how many cartons he can buy. 12/3 = 4. So the maximum amount he can buy is 4 cartons.
Answer:
(4.5,0) x intercept
(0,-1) y intercept
Step-by-step explanation:
f(x) = log (2x+1) -1
y = log (2x+1) -1
To find the x intercept, set y = 0 and solve for x
0 = log (2x+1) -1
Add 1 to each side
1 = log (2x+1)-1+1
1 = log (2x+1)
Raise each side to the power of 10
10^1 = 10^ log(2x+1)
10 = 2x+1
Subtract 1 from each side
10-1 = 2x+1-1
9 = 2x
Divide by 2
9/2 =2x/2
4.5=x
The x intercept is 4.5
(4.5,0)
To find the y intercept, set x = 0 and solve for y
y = log (1) -1
y = 0 -1
y = -1
The y intercept is -1
(0,-1)
