Answer:
An equation in the slope-intercept form is:
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where m is the rate of change or slope and b is the y-intercept
Given
- Let x represent the time in months
-
Let y represent the amount of money remaining in the account.
Given that every month Monica withdraws $15 from this account for her contact lenses
-
so, the rate of change or slope = m = 15
Given that after 3 months she has $255 left in her account.
i.e. (3, 255)
substituting
,
and
in the slope-intercept form to determine the y-intercept


switch sides



Thus, the y-intercept b = 210
Now, substituting
and
in the slope-intercept form of the line equation


Hence, an equation in the slope-intercept form is:
You would divide 1350 by 47 to find our how many strings of lights she would need.
1350 / 47 = 28.7234
note that IF you choose 28, you would run short because it would not be enough to cover all of that edge.
so you would need to round up to 29
therefore our answer would be D)29 strings of lights.
Answer:
Each side of the rhombus is 21 inches
Step-by-step explanation:
A rhombus has 4 equal sides: So all sides are the same
So you take the total perimeter and divide it by 4
84/4=21
