Answer 2

The equation that represents the total score points will be y = - (4/34)x + 49.58.

What is the equation of a line passing through two points?

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂). Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)\\[/tex]

The two points are (107, 37) and (73, 41).

Let 'x' be the number of minutes and 'y' be the total score. Then the equation is given as,

(y - 41) = [(41 - 37) / (73 - 107)](x - 73)

y - 41 = - (4/34)(x - 73)

y = - (4/34)x + 49.58

The equation that represents the total score points will be y = - (4/34)x + 49.58.

Answers

Answer:

Miles in 10 gallons = 195

Miles in 1 gallon = 195/10 = 19.5

Miles in 18 gallons = 19.5 × 18 = 351 miles.

Answer:

Miles travelled by the car on 10 gallons of gas = 195 miles

Miles travelled by the car in 1 gallon of gas = 195 ÷ 10 = 19.5 miles

Miles travelled by the car in 18 gallons of gas = 19.5 × 18 = 351 miles.

x² - 8x + 3x - 24 = 0

(x² - 8x) + (3x - 24) = 0

x(x - 8) + 3(x - 8) = 0

(x + 3)(x - 8) = 0

A profit is made when X>4, or after 4 thousand units.

Step-by-step explanation:

For starters the question states that for a profit to be made P(x) has to be greater than 0, and if you solve P(x) to equal 0 you get 4. Anything after 4 thousand would net the company a profit. You can also graph the equation and the x intercept, or 4 is also answer.

The midpoint is (10, 4)

Step-by-step explanation:

To find the midpoint, you add the x value from the first coordinate and the x value from the second coordinate, then divide by two to get the x coordinate of the midpoint. You do the the same exact thing with the two y values to find the y coordinate of the midpoint.

Answers

Answer:

a) 1000+0.05x ≥2200

b) x=24000

Step-by-step explanation:

a) So we know that Nadia for certain gets paid $1000 each month. That is a concrete amount that doesn't change, so the variable (x) would be placed on the 5% she earns from sales. We don't know how much she sells each month because it varies, so that will be represented by the X. Her goal is to raise NO LESS than $2200, which means the amount she earns from sales has to be greater than or equal to $2200.

b) From here just solve the equation for X:

Step-by-step explanation:

Regard (3, -2) and (7, 6) as the two acute angle vertices of a right triangle.  The horizontal leg of this triangle has the length (7 - 3) = 4, and the vertical leg 6 - (-2) = 8.  

Apply the Pythagorean Theorem to find the length of the diagonal connecting these two points.  This length is the distance between the two points:

d = √(4² + 8²) = √(16 + 64) = √80 + √16√5 = 4√5, or approximately 8.9

It ought to be axiomatic in thiscountry that every man must devote a reasonable share of his time to doing his duty in the Political life of the community. No man has aright to shirk his political duties under whatever plea of pleasure or business; and while such shirking may be pardoned in those of smallcleans it is entirely unpardonable in those among whom it is most common-in the people whose circumstances give them freedom in thestruggle for life. In so far as the community grows to think rightly, it will likewise grow to regard the young man of means who shirks hisduty to the State in time of peace as being only one degree worse than the man who thus shirks it in time of war. A great many of our menin business, or of our young men who are bent on enjoying life (as they have a perfect right to do if only they do not sacrifice other things toenjoyment), rather plume themselves upon being good citizens if they even vote; yet voting is the very least of their duties, Nothing worthgaining is ever gained without effort. You can no more have freedom without striving and suffering for it than you can win success as abanker or a lawyer without labor and effort, without self-denial in youth and the display of a ready and alert intelligence in middle age.
