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 )
I think the answer would be B
Answer:
which is an irrational number
Step-by-step explanation:
Recall that the repeating decimal 0.7373737373... can be written in fraction form as:
Now, let's write the number 147 which is inside the square root in factor form to find if it has some perfect square factors:
Then, 7 will be able to go outside the root when we compute the final product requested:
This is an irrational number due to the fact that it is the product of a rational number (quotient between 511 and 99) times the irrational number
x = 13
subtract x from both sides of the equation
6 = 2x - x - 7
6 = x - 7
add 7 to both sides
6 + 7 = x ⇒ x = 13
As a check
substitute this value into the equation and if both sides are equal then it is the solution
left side = 13 + 6 = 19
right side = (2 × 13) - 7 = 26 - 7 = 19
hence x = 13 is the solution
Answer:
Step-by-step explanation:
The y-intercept cannot be (2,-8). The x-coordinate of the y-intercept is 0.
Point-slope equation for line of slope -5 that passes through (2,-8):
y+8 = -5(x-2)
