Answer:
slope: 3y-intercept: 10equation: y = 3x +10Step-by-step explanation:
The two-point form of the equation of a line can be used.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
For the two points, we choose to use ones near (0, 0):
(x1, y1) = (-8, -14) and (x2, y2) = (14, 52)
Then our equation is ...
y = (52 -(-14))/(14 -(-8))(x -(-8)) -14
y = 66/22(x +8) -14
y = 3x +24 -14
y = 3x +10 . . . . . the equation
The slope is the coefficient of x: 3.
The y-intercept is the added constant: 10, or coordinates (0, 10).

I am pretty sure that it is right so I hope this helps!
In {(-4, 3), (-2, 7), (-1,0), (4, -3), (11, -7)} function has an inverse that is also a function. Therefore, option A is the correct answer.
What is inverse function?Inverse function is represented by f⁻¹ with regards to the original function and the domain of the original function becomes the range of inverse function and the range of the given function becomes the domain of the inverse function. The graph of the inverse function is obtained by swapping (x, y) with (y, x) with reference to the line y = x.
We know that a function is only a function such that there is a unique value of y corresponding to x.
An inverse function will only be a function if the function which is going to be inverse is a function.
In {(-4, 3), (-2, 7), (-1,0), (4, -3), (11, -7)} all value of x corresponding to y are different but in all remaining options the values are repeating hence that will be not a function since only option A has to inverse.
Therefore, option A is the correct answer.

What is a polygon?A polygon is a closed more than two-sided and can be made up of a finite number of straight line segments and is a type of planar figure in geometry.
Each line of the polygonal circuit's segments is referred to as its edges or sides.
We know the sum of interior angles in a hexagon is 720°.
∴ 135° + (5x - 4)° + (3x + 31)° + (7x - 64)° + (4x + 15)° + (6x - 8)° + 120° = 720°.
5x + 3x + 7x + 4x + 6x = (720 - 135 + 4 - 31 + 64 - 15 + 8 - 120)°.
25x = 495°.

4 kg of sugar would contain [tex] 1.2 \times 10^9 [/tex] crystals.
Step-by-step explanation:
Given that 3kg of sugar contains 9 × 10⁸ crystals, let "x" represent the number of sugar crystals 4kg of sugar would contain.
Thus, set up a proportion as follows:
3 kg : 9 × 10⁸ = 4 kg : x
[tex] \frac{3}{9 \times 10^8} = \frac{4}{x} [/tex]
Solve for x. Cross multiply.
[tex] 3 \times x = 9 \times 10^8 \times 4 [/tex]
[tex] 3x = 36 \times 10^8 [/tex]
[tex] 3x = 3.6 \times 10^9 [/tex]
Divide both sides by 3
[tex] \frac{3x}{3} = \frac{3.6 \times 10^9}{3} [/tex]
[tex] x = 1.2 \times 10^9 [/tex]
4 kg of sugar would contain [tex] 1.2 \times 10^9 [/tex] crystals.
Lucy has a goal of walking at least 15 miles she walks at a rate of 5 miles per hour which inequality can Lucy used to find H the number of hours she should walk in order to meet or exceed her goal
Answers
Answer:
5h>15
Step-by-step explanation:
✓From the question, we were informed that Lucy walks at a rate of 5 miles per hour, this implies that 5 is multiplied by amount of hours (5×1h)= 5h
✓ we need to find the inequality that Lucy can use to find H the number of hours she should walk in order to meet or exceed her goal, To find this as equation, we know that Lucy must walk for at least 15 miles which implies that the (5h) will always be greater than 15 miles. We can put it in equation as

Question:
1. Write an equation of the line that is parallel to y = -4x + 8 and passes through the point (5, 1).
2. Write an equation of the line that is perpendicular to y = -4x + 8 and passes through the point (5,1).
Answers
Answer:
Explanation is written below.
Step-by-step explanation:
1)
Given the line
[tex]y = -4x + 8[/tex]
Comparing with the slope-intercept form of the line equation
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept
So, the slope of the line = m = -4
We know that the parallel lines have equal slopes.Thus, the equation of the line that is parallel to y = -4x + 8 and passes through the point (5, 1), using point slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
Here, m is the slope and (x₁, y₁) is the point
substituting the values m = -4 and the point (5, 1)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
y-1 = -4 (x - 5)
y-1 = -4x+20
y = -4x+20+1
y = -4x + 21
2)
Given the equation
[tex]y = -4x + 8[/tex]
Comparing with the slope-intercept form of the line equation
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept
So, the slope of the line = m = -4
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be: 1/4
Thus, an equation of the line that is perpendicular to y = -4x + 8 and passes through the point (5,1), using point slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
Here, m is the slope and (x₁, y₁) is the point
substituting the values m = 1/4 and the point (5, 1)
[tex]y-1\:=\:\frac{1}{4}\:\left(x\:-\:5\right)[/tex]
Add 1 to both sides
[tex]y-1+1=\frac{1}{4}\left(x-5\right)+1[/tex]
[tex]y=\frac{1}{4}x-\frac{1}{4}[/tex]

Answer:
412 Oatmeal Raisin and 103 Chocolate Chip
Step-by-step explanation:
This can be solved using a system of equations. The two equations are C (chocolate) + O (oatmeal raisin) = 525 and the equation 4C+10=O. Then solving using elimination for systems of equation you can calculate that C=103, then plugging this number into one of the original equation you can calculate that O = 412.
