To write something in slope-intercept form
⇒ need to know what slope-intercept looks like: [tex]y = mx +b[/tex]
m: the value of the slopeb: y-interceptLet us first find the slope:
Formula of slope = [tex]\frac{y2-y1}{x2-x1}[/tex]
(x1,y1): (5,6)(x2,y2): (8,4)Slope = [tex]\frac{4-6}{8-5} =-\frac{2}{3}[/tex]
Lets now write in point-slope form:
⇒ [tex](y-y0)=m(x-x0)[/tex]
(x0,y0): any point on the line --> (5,6)m: value of slope[tex]y - 6 = -\frac{2}{3} (x-5)[/tex]
To write it into slope-intercept form, we must solve for y
[tex]y = -\frac{2}{3}(x-5)+6 =-\frac{2}{3}x+\frac{10}{3} +6\\y = -\frac{2}{3} x+\frac{10}{3}+\frac{18}{3} \\y = -\frac{2}{3}x+\frac{28}{3}[/tex]<-- slope-intercept form

If n'(x) = 2sin(2x) and n(0) = 0 what is the absolute maximum of n(x) on (0,2-}?
The absolute maximum of n(x) = 1 - 2 · cos 2x, whose first derivative is n(0) = 0, exists at x = 0.5π on (0, 2π]. The value of the absolute maximum is 3.
How to find the absolute maximum of a differentiable function
A function is differentiable in a given interval if and only if its derivative exists for every value of the interval. To determine the absolute maximum of n(x), we need to integrate the given function, apply first derivative and second derivative test and finally evaluate n(x).
First, we integrate n'(x) in terms of x:
n(x) = 2 ∫ sin 2x dx = 2 · (- 0.5 · cos 2x) + C = - cos 2x + C
- cos 0 + C = 0
C = 1
Then, n(x) = 1 - 2 · cos 2x.
Now we proceed to apply first and second derivative tests:
First derivative test2 · sin 2x = 0
sin 2x = 0
2 · x = sin⁻¹ 0
2 · x = π ∨ 2π
x = 0.5π ∨ π
Second derivative testn''(x) = 4 · cos 2x
n''(π) = 4 · cos 2π
n''(π) = 4
There is an absolute minimum for x = π. [tex]\blacksquare[/tex]
n''(0.5π) = 4 · cos π
n''(0.5π) = - 4
There is an absolute maximum for x = 0.5π. [tex]\blacksquare[/tex]
Finally, we evaluate n(x) for x = 0.5π to determine the absolute maximum:
n(0.5π) = 1 - 2 · cos π
n(0.5π) = 3
The absolute maximum of n(x) = 1 - 2 · cos 2x, whose first derivative is n(0) = 0, exists at x = 0.5π on (0, 2π]. The value of the absolute maximum is 3. [tex]\blacksquare[/tex]
RemarkThe statement of the question is poorly formatted and reports several mistakes, correct form is introduced below:
If n'(x) = 2 · sin 2x and n(0) = 0. What is the absolute maximum of n(x) on (0, 2π]?

Answer:
{x : x > 5}
Step-by-step explanation:
-4x - 5 < -25
-4x < -20
When dividing/multiplying both sides with a negative number, change the inequality symbol to the opposite direction. e.g. < to > or > to <.
x > -20/-4

Sonnie deposited $2,500 into an account that earns simple interest. After 5 years, she earned $375 in interest. What was the interest rate of the account?
Answer:
3%
Step-by-step explanation:
The interest on the account is given by the simple interest formula:
I = Prt
where I is the interest, P is the principal invested, r is the annual rate, and t is the number of years
375 = 2500r(5) . . . . . . using the given values in the formula
375/12500 = r = 0.03 . . . . . divide by the coefficient of r
Sonnie's account had a 3% interest rate.

Y is
inversely proportional to the square of x.
The Given that y = 10 for a particular value of X,
find the value of y
when this value of x
is halved.
Answer:
y = 40
Step-by-step explanation:
y = k/x²
Let a = the x-value corresponding to y = 10
For x = a, y = 10
10 = k/a²
k = 10a²
The function is:
y = 10a²/x²
Now we halve the x-value a:
Let x = a/2.
y = 10a²/x²
y = 10a²/(a/2)²
y = 10a²/(a²/4)
y = 40
Solve 64x2 - 121 = 0 using square roots.
Using the square root property to solve this 64x² - 121 = 0, the value of x is - 11 / 8 and 11 / 8.
How to solve quadratic equation using square root property?64x² - 121 = 0
add 121 to both sides of the equation
64x² - 121 + 121 = 0 + 121
64x² = 121
divide each term by 64 and simplify
64x² / 64 = 121 / 64
x² = 121 / 64
Take the square root of both sides of the equation to eliminate the exponent on the left side
√x² = ±√ 121 / 64
Simplify the right side of the equation.
x = ± 11 / 8
Therefore,
x = 11 / 8, - 11 / 8
