The simple answer to this question is purple. However, because of the nature of the color pink, it can vary based on that. Purple is secondary color itself, as it’s the byproduct of red and blue. However, because there is some white in there from the pink, we are going to get a variety of shades.

X+4p = 86 - - - - (1)

X+6p=104 - - - - - (2)

Re arrange equation (1)

X=86-4p-----(3)

Substitute (3) in (2)

86-4p +6p=104

86+2p=104. (subtract 86 from both side)

2p = 18. (divide by 2 from both side)

Then p =$9

Answer:

y = 7

Step-by-step explanation:

Mathematically, according to the Pythagoras’ theorem;

The square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the two other sides

The hypotenuse is the side that faces the right angle and it is represented by the square root of 85 here

Thus, we have it that;

(√85 )^2= 6^2 + y^2

85 = 36 + y^2

y^2 = 85-36

y^2 = 49

y = √49

y = 7

examine this graph. what are the y-intercept and slope of this line HELP PLLZ

Answers

Answer:

y-intercept is basically the y variable. Looking on the graph above your y-intercept is 2. To find slope it is rise / run. In the graph your slope is -2/3.

Hope this helps, thank you :) !!

The required slope of the given equation of the line shown in the graph is -2/3.

Given that,
A graph of the line has been shown, we have to determine the slope of the line.

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,

Since the slope of the line is measure of the angle inclined with the axis
As from observation, the line is passing from points (0,2) and (3, 0).
The slope of the line,
m = (y₂ - y₁) /  (x₂ - x₁)
m = (0 - 2) / (3 - 0)
n = -2/3

Thus, the required slope of the given equation of the line shown in the graph is -2/3.
