Answer:
f(2) = 12
f(x) = 7, x = -3, 1
Step-by-step explanation:
<u>a)</u>
plug in x as 2
f(x) = 2^2 + 2(2) + 4
f(x) = 4 + 4 + 4
f(x) = 12
<u>b)</u>
replace f(x) with 7
7 = x^2 + 2x + 4
x^2 + 2x - 3 (move 7 to other side)
Factor
ac: -3x^2
b: 2x
split b into 3x, -x
(x^2 -x) + (3x - 3)
↓ ↓
x(x-1) + 3(x-1)
Factor: (x-1)(x+3) = 0
Solve using Zero Product Property:
x - 1 = 0, x + 3 = 0
x = 1, x = -3
Answer:
Step-by-step explanation:
The point-slope form of a line is given by:
Where
(x_1,y_1) is the coordinate pair (any of the points given)
m is the slope. The ratio of change in y coordinates by x coordinates
Let's calculate the slope:
Now, it is given "y - 4", so y_1 is 4, so they are using the coordinate pair (7,4). So we can say x_1 = 7
Now we have all the values, lets write the equation:
This is the point-slope form.
Answer:
Dividends = $105000
So option (c) will be correct answer
Step-by-step explanation:
We have given that Retained earning on 12/31/18 is $475000
And retained earning on 12/31/18 is $445000
Net income = $135000
Change in retained income = $475000-$445000 = $30000
We have to find dividends
We know that dividends is given by
Dividends = net income - change in retained income = $135000-$30000 = $105000
So option (c) will be correct answer
The first two rows of coefficients are identical, so by inspection, the determinant is 0.
I'm not 100% but I'm pretty sure the answer is True
