Answer:
Part 1) The graph in the attached figure
Part 2) The equation of the line is
Step-by-step explanation:
Part 1) we know that
To graph a line we need at least two points
we have
(5,2) and (0,7)
Plot the points
Connect then and join to graph the line
The graph in the attached figure
Part 2) Determine the equation of the line
Find the slope
Remember that the formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
see the graph
The formula to calculate the slope between two points is equal to
we have
substitute
Is negative because is a a decreasing function
as the value of x increases, the value of y decreases
The equation of the line in slope intercept form is equal to
we have
----> the y-intercept is given see the graph
substitute
Answer:
Scientific notation is given by ax10^b therefore on solving .0002985g you will get 2.985x10^-4gm
Mass of 5,00,000 of such puppy is
500000x.0002985
FINAL: 149.25 gm.
Answer:
days ≤ 6
Step-by-step explanation:
she gas 160 pages out of the 380 pages, so she needs to write other:
380 - 160 = 120 pages.
If she writes a minimum of 20 pages per day, then the maximum number of days in which she will finish the book is:
20*d = 120
d = 120/20 = 6
so d is the number of days, and we have that:
d ≤ 6.
The equality is when she only writhes 20 pages per day, and if she writes more than that, then the number of days needed will be smaller than 6.
Answer:
y = 2x + 8
Step-by-step explanation:
We want an equation of the form y = mx + b (slope-intercept).
Look what happens to x as we go from (0, 8) to (1, 10): x increases by 1. This is the 'run' as we calculate the slope.
At the same time, y increases by 2 from 8 to 10.
The slope is defined as m = rise / run, and here is m = 2/1, or m = 2.
Write out y = mx + b and substitute 2 for m: y = 2x + b.
To find the y-intercept, substitute 0 (from (0, 8) ) for x and 8 for y:
8 = 2(0) = b, so b = 8, and the desired equation is
y = 2x + 8
You would take the number of pounds you want to buy (3.5) and multiply it by how much it costs per pound ($3.48).
It will look like this
(3.5)(3.48)
