Answer:
y = -3/4x + 7
Step-by-step explanation:
ok first u need to find the slope so use the slope equation for this (x2 - x1 over y2 - y1) so
1 - 4 = -3
8 - 4 4
so the m is -3/4
now you need to find the y intercept so pick one of the points (let's do (8, 1)) and plug that into the slope intercept form (y = mx+b)
so 1 = -3/4(8) + b
1 = -6 + b
+ 6 + 6
b = 7
so the equation is y = -3/4x + 7. hope this helps

On a certain route, an airline carries 5000 passengers per month, each paying $40. A market survey indicates that for each $1 increase in the ticket price, the airline will lose 100 passengers. Find the ticket price that will maximize the airline's monthly revenue for the route. What is the maximum monthly revenue?
Find the equation of a line that is perpendicular to the line x=-9 and contains the point (-8,1)
Step-by-step explanation:
the line x = -9 had only one valid x value (-9), but then all values for y between -infinity and +infinity are valid.
does this sound familiar ?
it should, because the y-axis is the same type of line.
it is x = 0.
so, x = -9 is simply parallel to the y-axis.
and any line perpendicular to it (crosses the original line in a right angle = 90 degrees) is then parallel to the x-axis.
there the situation is upside-down: there is only one valid y value, and all values between -infinity and +infinity are valid x values.
since the specified point on that line has y = 1, it means that the whole line is
y = 1

Write the sentence as an inequality.
The sum of x and 5 is greater than 6 OR less than 0.
Answer:
|x+2| > 3
Step-by-step explanation:
We know that if |x| > a then (-a > x) ∨ (x > a).
(x+5 > 6) ∨ (x+5 < 0) ⇒ (0 > x+5) ∨ (x+5 > 6) |-3 ⇒

Answer:
parallel: y = -7x -44perpendicular: y = 1/7x -8/7Step-by-step explanation:
The given equation is in slope-intercept form:
y = mx +b . . . . . . line with slope m and y-intercept b
For the purpose of this question, you need to recognize that the line with equation ...
y = -7x +8
has a slope (x-coefficient) of -7.
The parallel line will have the same slope (x-coefficient).
The perpendicular line will have a slope that is the opposite reciprocal of this:
m = -1/(-7) = 1/7
Each line will have a y-intercept (b) that makes the line go through the given point. The y-intercept can be found by solving the slope-intercept equation for b:
b = y - mx . . . . . . where (x, y) is the point you want the line to go through
__
parallel line:
b = -2 -(-7)(-6) = -2 -42 = -44
The equation of the parallel line is y = -7x -44.
__
perpendicular line:
b = -2 -(1/7)(-6) = -14/7 +6/7 = -8/7
The equation of the perpendicular line is y = 1/7x -8/7.

The figure below shows parallel lines cut by a transversal:
A pair of parallel lines is shown, cut by a transversal. Angle 7 is located in the upper right exterior corner on the top line, and angle 8 is located in the upper left exterior corner of the top line.
Which statement is true about ∠7 and ∠8? (4 points)
∠7 and ∠8 are supplementary because they are a pair of corresponding angles.
∠7 and ∠8 are complementary because they are a pair of adjacent angles on a straight line.
∠7 and ∠8 are congruent because they are a pair of adjacent angles on a straight line.
∠7 and ∠8 are supplementary because they are a pair of adjacent angles that form a straight line.
Answer:
D Sorry if I am wrong mark me brainleist is right
Step-by-step explanation:
When two adjacent angles are formed at a point on a line so that sum of their measures is 180°, angles are called as supplementary to each other.
In the figure attached, ∠7 and ∠8 are supplementary because they are a pair of adjacent angles that form a straight line.

Answer: 0.4761904762 or 10/21
Step-by-step explanation: Set up the problem so that 2/7 is divided by 3/5. This gives you [tex]\frac{2}{7}/\frac{3}{5}[/tex]. Next, cross multiply to find the numerator and the denominator. So 2 x 5 = 10 and 7 x 3 = 21. This gives you 21/10. Now switch the numerator and the denominator so that they are each in the right place. This gives you 10/21. In order to find the decimal, divide the numerator by the denominator to get the decimal. This gives you the answer 0.4761904762 or ≈ 0.48
Show work:
[tex]\frac{2}{7}/\frac{3}{5}[/tex]
[tex]2 *5=10[/tex]
[tex]7 *31 =21[/tex]
[tex]\frac{10}{21} = 0.4761904762[/tex]

a company that manufactures computers has a monthly fixed cost of $1,000. if it sells 400 computers each month, what is its average fixed cost?
Based on the number of computers sold by this company in a month, their average fixed cost is $2.50 per computer.
The average fixed cost is acquired by dividing the total fixed cost in a period by the total amount of production in that same period.
The average fixed cost here is therefore:
= Fixed cost / Number of computers
= 1,000 / 400
= $2.50 per computer
In conclusion, the average fixed cost is $2.50 per computer.

[tex] \sqrt{528} = 22.978250[/tex][tex] \sqrt{528} \approx23[/tex](x + 2)(x + 3)(x + 4) can be written in the form x + ax² + bx + c
where a, b and care positive integers.
Work out the values of a, b and c.
Answer:
[tex]a=9, b=26, c=24[/tex]
Step-by-step explanation:
Let's expand the expression bit by bit.
[tex](x+2)(x+3)=(x)(x)+(x)(3)+(2)(x)+(2)(3)=x^2+5x+6[/tex] by FOIL.
We have that [tex](x^2+5x+6)(x+4)=x(x^2+5x+6)+4(x^2+5x+6)=x^3+5x^2+6x+4x^2+20x+24=x^3+9x^2+26x+24[/tex].
So, the answer is [tex]\boxed{a=9, b=26, c=24}[/tex]
A cubic polynomial is a type of polynomial with the degree of 3 i.e. the highest exponent of the variable is 3.
The general form of a cubic polynomial is written as p(x): ax³ + bx² + cx + d, a ≠ 0, where a, b, and c are coefficients and d is the constant with all of them being real numbers.
Given:
(x + 2)(x + 3)(x + 4)
Now, Multiplying the monomial
= (x² + 2x + 3x+ 6 ) ( x+4)
= (x² + 5x+ 6 ) ( x+4)
= x³ + 4x² + 5x² + 20x + 6x+ 24
= x³ + 9x² + 26x+ 24
Now, Comparing it with the standard form of cubic Polynomial
ax³ + bx² + cx + d
So, a= 1, b= 9, c= 26 and d= 24.

<=> 24x + 12x = 40 + 10
<=> 36x = 50
<=> x = 50/36
<=> x= 25/18
