Answer:

The equation is

y = $ 12.35 x

Step-by-step explanation:

Cost of one bag of rocks = $ 12.35

Let there are x bags of rocks, so that the total cost is y.

So, the cost of 1 bag = $ 12.35

cost of x bags = $12.35 x

The total cost is

y = $12.35 x

It is the equation of a straight line which passes from origin and the slope is 12.35.

2 water taps A B fill a tank in 12 hrs. Tap A takes 10 hrs less than tap B to till tank separately. Find time taken by tap B to

Hatshy [7]

Answer:

11 hours

Step-by-step explanation:

Setting up a system of equations and using the substitution method will give you the number of hours used by each tap. Let a = time for tap A and b = time for tap B:

a + b = 12 (A and B fill a tank in 12 hours)

a = b - 10 (tap A takes 10 hours less than tap B)

Substitute 'b - 10' for 'a' in the first equation:

b - 10 + b = 12

Combine like terms: 2b - 10 = 12

Add 10 to both sides: 2b - 10 + 10 = 12 + 10 or 2b = 22

Divide by 2: 2b/2 = 22/2

Solve for b: b = 11 hours

A line contains the points (-26, -37) and (32, -61)

Slav-nsk [51]

The slope of line through given points is -12/29

Step-by-step explanation:

Given points are:

(-26, -37) and (32, -61)

Let

(x1,y1) =(-26, -37)

And

(x2,y2) = (32, -61)

Slope (steepness) of a line, denoted by m, is given by the formula

$m = \frac{y_2-y_1}{x_2-x_1}$

Putting the values

$m = \frac{-61-(-37)}{32-(-26)}\\\\=\frac{-61+37}{32+26}\\\\=\frac{-24}{58}\\\\=-\frac{12}{29}$

Hence,

The slope of line through given points is -12/29
