The equivalent expression of 2(x² – 1) + 3x(x – 4) is 5x² - 12x - 2
Here, we have,
We know that,
The equivalent expression of the expression can be found as follows;
2(x² – 1) + 3x(x – 4)
open the brackets
2x² - 2 + 3x² - 12x
Therefore, let's combine like terms
2x² + 3x² - 12x - 2
Let's do the arithmetic for like terms
2x² + 3x² - 12x - 2
5x² - 12x - 2
Therefore, the equivalent expression of 2(x² – 1) + 3x(x – 4) is
5x² - 12x - 2.

Easy buddy....
[tex]2 x + 68 = 180[/tex]
Subtract the sides of the equation minus 68
[tex]2x = 180 - 68[/tex]
[tex]2x = 112[/tex]
Divided the sides of the equation by 2
[tex]x = \frac{112}{2} = 56 \\ [/tex]
So ;
[tex]x = 56 \: degreees[/tex]

Find the directions in which the function increases and decreases most rapidly at P0. Then find the derivatives of the function in those directions.
Answer and Step-by-step explanation:
SOLUTION:
Given function:
h (x, y, z) = ln (x2 + y2 – 1) + y +6z, p0(1, 1, 0)
Derivatives of the function:
∂h / ∂x = (1 / x2 + y2 -1). (2x)
= 2x / x2 + y2 -1
∂h/∂y = (1 / x2 + y2 – 1) (2y + 1)
= (2y / x2 + y2 -1) + 1
∂h / ∂z = 6
Now compute the partial derivatives:
∂h (1, 1, 0) / ∂x = 2(1) / 1 +1 -1
= 2
∂h(1, 1, 0) / ∂y =( 2(1) / 1 +1 -1) + 1
= 3
∂h (1, 1, 0) / ∂z = 6
Δh (1,1,0) = ( 2, 3, 6)
The definition of gradient is:
Δf (x, y, z) = (∂f / ∂x , ∂f / ∂y)
Put the coordinate values to arrive at solution:
Umax = Δh (1,1,0) / | Δh (1,1,0) |
= (2, 3, 6) / |2, 3, 6|
= (2, 3, 6) / √(22+33+62)
= (2, 3, 6) / √49
= (2, 3, 6) / 7
= (2/7 , 3/7, 6/7)
Umin = - U max = ( -2/7, -3/7, -6/7)
Compute direction by finding unit vector:
Du h max = Δh (1,1,0) . u max
= (2, 3, 6) . (2/7, 3/7, 6/7)
= 2(2/7) + 3(3/7) + 6(6/7)
= 4/7 + 9/7 +36/ 7
= 49 / 7
= 7
Du h min = -Du h max
= -7

Find g (a + 1 ), if g(x)=5x-3
Answer:
g(a+1)=5a+2
Step-by-step explanation:
so (a+1) is the value of x
you can write it like this:
x=a+1
using substitution, we can swap out all 'x's for 'a+1's. like so;
g(a+1)=5(a+1)-3 -- given
=5a+5-3 -- distribute
=5a+2 -- simplify!

What is the slope of the line that contains these point?
(13,11),(14,6),(15,1),(16,-4)
Answer:
Step-by-step explanation:
You can easily find the slope by using two points. Let’s use (13, 11) and (14, 6)
We look at the slope equation as: y2 - y1 divided by x2 and x1.
13 = x1 11= y1 and 14= x2 6=y2
Plug in: 6-11/14-13 and solve
Answer: -5
Hope I made sense :)
Answer:
Slope (m) = -5
Step-by-step explanation:
*If all the given four points are on a straight line then; the slope derived from first two points should be equal to the slope derived from the next to points.
Let's verify this ...
For the first two points:
Slope (m) = change in y ÷ change in x = [tex]\frac{6 - 11}{14 - 13} = \frac{-5}{1} = -5[/tex]
For the next two points:
m = [tex]\frac{-4 - 1}{16 - 15} = -5[/tex]
*Proved ∴ points (13,11) , (14,6) , (15, 1) and (16,-4) are on the same line.
We can find the equation of this line and ascertain that the four points are on a single line.Taking another point (x,y) on the line and point (13,11);
m = [tex]\frac{y - 11}{x - 13} = -5[/tex]
y = -5x + 65 + 11
y = -5x + 76
