Answer (this one's written in slope-intercept form):
Step-by-step explanation:
1) Lines that are parallel to each other have the same slope. The line 
is in slope intercept form, or 
form, and the number in place of 
represents the slope. Knowing this, it looks like 
is in the place of the in that equation, so is the slope - and the slope we need to use for the answer, too.
2) Once you know a point that the line must pass through and a slope, you can write an equation with point-slope form, or 
. is the slope and 
and 
are the x and y values of the point it must pass through. So, substitute for , 0 for , and -3 for . Simplify and isolate y to put it in slope-intercept form:
3) Thus, 
is the answer. It's written in slope-intercept form.
Answer: 9.25
Step-by-step explanation:
So first divide 420 by 3 which gets you 140 so now you need to divide that 140 by 20 which is 7 so the jeweler could make 7 necklaces which is B. If you have any questions just ask. Hope I helped you ❤️
