Answer:
15 grams
Step-by-step explanation:
If the copper made up 80% of the weight of the bar (w), then the bar weighed ...
0.80w = 12 g
w = (12 g)/0.80 = 15 g
_____
Copper has a density of about 8.96 g/cm³, so Nancy's "large" metal bar is about the size of two sugar cubes.
Answer (<u>assuming it can be written in slope-intercept form)</u>:
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula, 
. Substitute the x and y values of the given points into the formula and solve:
So, the slope is 
.
2) Now, use the point-slope formula 
to write the equation of the line. Substitute 
, 
, and 
for real values.
Since represents the slope, substitute for it. Since and represent the x and y values of one point the line intersects, choose from any one of the given points (it doesn't matter which one, either way the result equals the same thing) and substitute its x and y values into the formula as well. (I chose (4,5), as seen below.) From there, isolate y to place the equation in slope-intercept form (
format) and find the following answer:
