The equation of line is y = ( 3/2 )x - 7 , where the slope is m = 3/2
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = 3/2
The y-intercept is b = -7
And , equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
So , y = ( 3/2 )x - 7
Hence , the equation of line is y = ( 3/2 )x - 7

The polynomial 3x2 – 10x 8 has a factor of 3x – 4. what is the other factor of 3x2 – 10x 8?
The other factor of the polynomial [tex]\rm 3x^2-10x+8[/tex] is ( x - 2 )
It is given that the polynomial [tex]\rm 3x^2-10x+8[/tex] has a factor of [tex]\rm (3x-4)[/tex].
It is required to find the other factor.
What is Polynomial?Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
We have polynomial:
[tex]\rm = 3x^2-10x+8[/tex]
Now by using the factorization method:
[tex]\rm = 3x^2-10x+8\\\rm = 3x^2-6x-4x+8\\\rm =3x(x-2)-4(x-2)\\\rm = (x-2)(3x-4)[/tex]

Find the sum of the geometric series 128 - 64 + 32 – ... - 1.
Step-by-step explanation:
this sequence has 8 terms and the common ratio or multiplication factor is -1/2.
we could add these 8 numbers manually or use the formula :
Sn = a1(1 - r^n)/(1 - n)
when r < 1 (like in our case -1/2).
S8 = 128(1 - (-1/2)⁸)/(1 - -1/2) =
= 128(1 - 1/256)/(3/2) = (128×255/256)/(3/2) =
= (255/2)/(3/2) = 255/2 × 2/3 = 255/3 = 85

A box contains:
3 red crayons
7 blue crayons
4 yellow crayons
8 green crayons
2 black crayons
1 orange crayon
A crayon is chosen at random and replaced 50 times. What is a reasonable prediction for the number of times a blue or orange crayon will be drawn?
Answer:
16 times
Step-by-step explanation:
We first have to find the total amount of crayons:
[tex]3+7+4+8+2+1=25[/tex]
That means that the box contains a total of 25 crayons. Of those 25 crayons, 7 are blue and 1 is orange. That means every time one crayon is chosen from the box, there is an 8 in 25 chance it will be blue or orange. We can represent that chance as a fraction: [tex]\frac{8}{25}[/tex]
That [tex]\frac{8}{25}[/tex] chance occurs each time ONE crayon is chosen, so if we want to know how many times blue or orange will be chosen after 50 times, we can multiply that chance by 50.
[tex]\frac{8}{25}*50=400/25[/tex]
Then you simplify the fraction:
[tex]\frac{400}{25}=16[/tex]
That means that if you pull crayons from the box 50 times, a blue or orange crayon will be likely drawn around 16 times.
