Answer:
slope=-1/2
y intercept =-2
Step-by-step explanation:
what u have to do is get y on 1 side and 3x on the other, so take away 3x from both sides which leaves you with 6y = -3x -12. then divide both sides by 6 to get y on it's own so you have y= -1/2x -2. this formula is y=mx+c the m is always the slope and the c is always the y intercept
Answer:
I am assuming the question is
-14(-8×12y)
112-168y
Step-by-step explanation:
you have to expand the brackets first.
then you can't do anything after expanding the brackets because they are not like terms
hope this was helpful
Answer:
Step-by-step explanation:
Given:
27 + 2/3 ÷ 3 + 9/10
In division, compatible numbers are numbers that can be divided mentally.
27 + 2/3 ÷ 3 + 9/10
27 + 0.67 ÷ 3 + 0.9
27.67 ÷ 3.9
= 7.0948717948717
Approximately
= 7
But, alternatively
27.67 ÷ 3.9
27.67 is closer to 28
3.9 is closer to 4
Therefore,
28 ÷ 4
= 7
The quotient of 27 + 2/3 ÷ 3 + 9/10 using compatible numbers is around 7
Answer:
f^-1 (9) = 7 equals f = 9/7
Step-by-step explanation:
f^-1 x 9 = 7, f ≠ 0
1/f x 9 = 7
9/f = 7
9 = 7f
7f = 9
Answer: -2, 0, 4
Set the equation equal to zero.
x³ - 2x² - 8x = 0
Factor out x in the equation, since all the terms (x³, -2x², and -8x) are divisible by x. You can check your accuracy using the Distributive Property.
x(x² - 2x - 8) = 0
Factor out the polynomial. To do this, find two numbers that multiply to get the last term, -8, and add together to get the middle term, -2. In this case, those two numbers are -4 and 2 (-4 × 2 = -8 and -4 + 2 = -2). Don't forget about the x that was factored out before!
x(x - 4)(x + 2) = 0
Set each factor equal to zero and solve for x. The factors in the equation are x, (x - 4), and (x + 2).
x = 4
x = -2
The zeros of the polynomial function are -2, 0, and 4.
