Answer:
Step-by-step explanation:
Factored form of quadratic equation:
x₁, x₂ - zeros
We have zeros: x₁ = -2 and x₂ = 2. Substitute:
We have the vertex (0, -4). Put the coordinates of the vertex to the equation:
<em>divdie both sides by (-4)</em>
Finally:
Answer:
Step-by-step explanation:
The computation of the magnitude is shown below:
Data provided in the question
Given points
R(3,7,-1), S(10,-4,0)
Now the distance lies between R and S
RS = (10 ,-4, 0) - ( 3 ,7, -1 )
= (10 - 3, -4 - 7, 0 - (- 1))
= (7, - 11, 1 )
After that, the magnitude is determined by using the following calculation part
Answer:
y = x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = , hence
y = x + c ← is the partial equation
To find c substitute (- 10, 6) into the partial equation
6 = - 2 + c ⇒ c = 6 + 2 = 8
y = x + 8
Elise's number is 29.
If you think of multiplying a value by -3 to get -33, it would obviously be 11.
So in this case, you would want to add 18 to 11 to get Elise's number, which is 29. Subtracting 18 from 29 would get you back to the value of 11, which you can then multiply it by -3 again to get -33.
