Answer:
- 6
Step-by-step explanation:
Given
y = 3(x - 1)(x + 2) ← expand factors using FOIL
= 3(x² + x - 2) ← distribute by 3
= 3x² + 3x - 6
To find the y- intercept let x = 0, thus
y = 3(0)² + 3(0) - 6 = 0 + 0 - 6 = - 6
Thus y- intercept = - 6 ⇒ (0, - 6 )
Answer:
C. -6n+5
Step-by-step explanation:
Area of a rectangle =l x w
A=(n-5)(n-1)
Use distributive property
-n-5n+5
Combine like terms
-6n+5
<span>f(x)=2x+1 and g(x)=x^2-7
(f+g)(x) = </span>2x + 1 + x^2 - 7
(f+g)(x) = x^2 + 2x - 6
answer
x^2 + 2x - 6
Answer: They must sell 116 more boxes to raise $270.
Solution:
For every box they sell, they get $1.35 profit.
They have sold 84 boxes already, then they have:
$1.35 * 84 = $113.40
They need $270, then they have to sell:
$270-$113.40=$156.60
For every box they sell, they get $1.35 profit, then they need to sell:
$156.60/$1.35=116 more boxes
Check:
116*$1.35=$156.60
84*$1.35=$113.40
$156.60+$113.40=$270.00
Answer:
x ≈ 7.9 ft
Step-by-step explanation:
cos∅ = adjacent over hypotenuse
Since we are dealing with a right triangle, we can use trigonometry to help us solve for missing values:
cos44° = x/11
11cos44° = x
x = 7.91274
x ≈ 7.9 ft
