Step-by-step explanation:
We will put this in y=mx +b form so first calculate the slope
m= (-4)-(-5)/(-4)-(-6)
m= 1/2. So y= x/2. +b
Now just substitute the x and y values of either given point to calculate b
I will use (-4,-4)
-4= (1/2)(-4) +b
-4= -2 +b
b=-2
So equation is y= x/2 -2

Answer:
Step-by-step explanation:
Equation of line in slope- y intercept form:
First find the slope.
[tex]\boxed{Slope= \dfrac{y_2-y_1}{x_2-x_1}}[/tex]
[tex]\sf = \dfrac{-4-[-5]}{-4-[-6]}\\\\=\dfrac{-4+5}{-4+6}\\\\=\dfrac{1}{2}[/tex]
Equation:
[tex]y =\dfrac{1}{2}x+b[/tex]
Choose any point and substitute the x and y value in the above equation.
(-6,-5)
[tex]\sf -5=\dfrac{1}{2}*(-6) + b\\\\-5 = -3+b\\\\-5+3=b\\\\-2 = b[/tex]
Equation:

Will mark BRAINLIEST and give extra points
Answer:
Step-by-step explanation:
1 and 4 are adjacent supplementary angles. This will mean that 180-68=112
<4=112 degrees
<3 is the same as 1 which is 68 since they are vertical angles.
<2 is also 112
Answer:
2=112
3= 68
4= 112
Step-by-step explanation:
Each line adds to 180
So subtract 68 and it will give you the opposite side(2) 112
the angle across from it has tha same value so 2 and 4 are the same mesure

Describe the transformation of f(x) = cos x to g(x) = cos(x - pie/4).
Answer:
The Answer is C.
Step-by-step explanation:
f(x) = cos x , g(x) = cos(x - π/4)
Equation: f(x) = a * cos (x - h) + k
Since the equation only has h = π/4, it means that it shift right.
Lin and Priya were working on solving this system of equations.
Lin's first move is to multiply the first equation by 3.
Priya's first move is to multiply the second equation by 2.
Explain why either move creates a new equation with the same solutions as the original equation.
Richard and Nestor create paintings. Richard creates 40 paintings in 28 days.
Nestor creates 45 paintings in 5 weeks. Who creates paintings at a faster rate?
Show your work
Answer:
Richard
Step-by-step explanation:
28 days=4 weeks
40 paintings in 4 weeks
45 paintings in 5 weeks
Richard weekly rate: 40/4=10 paintings per week
Nestor weekly rate: 45/5=9 paintings per week

Find area of cross-section, in this case an isoscles triangle so we know that both of the parallel lines are 3ft
To find the area of the cross-section, do:
3 x 3 = 9
9 ÷ 2 = 4.5 (Area of cross-section)
Since we don't know the length of h, we need do:
27^3 ÷ 4.5 = 6
Therefore 6 is h

Malik invests money in an account paying simple interest. He invests $80 and no money is added or removed from the investment. After one year, he has $83.20. What is the simple percent interest per year?
Answer:
4%
Step-by-step explanation:
The interest earned on the investment is the difference between the end-of-year value and the initial value:
$83.20 -80 = $3.20 . . . . simple interest per year
__
The interest rate is the ratio of this to the initial investment:
$3.20/$80.00 = 0.04 = 4% . . . . . simple interest rate per year

Answer:
[tex]\theta = \frac{\pi}{3} , \pi, \frac{5\pi}{ 3}[/tex]
Step-by-step explanation:
we want to solve the following trigonometric equation:
[tex] \displaystyle - 2 { \sin}^{2} (\theta )+ \cos( \theta) + 1 = 0, \: \theta \in [0,2\pi)[/tex]
The first step of solving trigonometric equation is to rewrite the equation in terms of one trigonometric function . With Pythagorean theorem, we know that sin²x=1-cos²x . It will be helpful to rewrite the equation in terms of one trig functions. Therefore, substitute 1-cos²[tex]\theta[/tex] in the place of sin²[tex]\theta[/tex]:
[tex] \displaystyle - 2 (1 - \cos ^{2} ) + \cos( \theta) + 1 = 0, \: \theta \in [0,2\pi)[/tex]
simplify:
[tex] \displaystyle\implies - 2 (1 - \cos ^{2} (\theta) + \cos( \theta) + 1 = 0, \: \theta \in [0,2\pi)\\\implies- 2 + \cos ^{2} (\theta)+ \cos( \theta) + 1 = 0, \: \theta \in [0,2\pi)\\\implies\cos ^{2} (\theta)+ \cos( \theta) -1 = 0 [/tex]
Consider cos² [tex]\theta\implies[/tex] x. Thus,
[tex]2 {x}^{2} + x - 1 = 0[/tex]
solving the quadratic equation yields:
[tex]{x}^{} = \frac{1}{2} \\ x = - 1[/tex]
back-substitute:
[tex] \begin{cases} \cos( \theta) = \dfrac{1}{2} \\ \cos( \theta) = - 1 \end{cases} \theta \in[0,2\pi)[/tex]
take inverse trig in both sides
[tex] \implies \begin{cases} \theta = \dfrac{\pi}{3} + 2n\pi\\\theta= \frac{5\pi}{3} + 2n\pi \\ \theta = \pi + 2n\pi\end{cases} \theta \in[0,2\pi) \\\\\implies\theta= \frac{\pi}{3}+\dfrac{2n\pi}{3},\theta\in [0,2\pi)\\\text{when n=0}\\ \implies \theta = \frac{\pi}{3} \\ \text{when n=1}\\ \theta= \pi\\ \text{when n=2}\\\theta=\frac{5\pi}{ 3} [/tex]
In conclusion,
[tex]\displaystyle\theta = \frac{\pi}{3} , \pi, \frac{5\pi}{ 3}[/tex]
A circle with two chords is shown below. What is the value of x? Round your answer to the nearest tenth.
Numbers given are 8, 20, and 36
The theorem state that the products of the lengths of the line segments on each chord are equal. The value of x from the figure is 15.75
Intersecting chord theoremThe theorem state that the products of the lengths of the line segments on each chord are equal.
According to the given diagram;
9 * 21 = 12 * x
189 = 12x
Divide both sides by 12
12x/12 .= 189/12
x = 189/12
x = 15.75
Hence the value of x from the figure is 15.75
