You can answer this problem using the midpoint formula, but we can work out the 4th vertex by just logically thinking it through by first drawing out the rhombus on an x-y coordinate plane. I wrote the answer out on paper since it is easier than typing. Let me know if you have any questions.
Answer:
last option
Step-by-step explanation:
b) 1/6 = 16.7 to 1dp
c) 45% = 45/100 = 9/20
d) 7/9 = 77.8% to 1dp
Answer:
Bottom left graph
Step-by-step explanation:
We have to use what is called the zero-interval test [test point] in order to figure out which portion of the graph these inequalities share:
−2x + y ≤ 4 >> Original Standard Equation
+ 2x + 2x
_________
y ≤ 2x + 4 >> Slope-Intercept Equation
−2[0] + 0 ≤ 4
0 ≤ 4 ☑ [We shade the part of the graph that CONTAINS THE ORIGIN, which is the right side.]
[We shade the part of the graph that does not contain the origin, which is the left side.]
So, now that we got that all cleared up, we can tell that the graphs share a region in between each other and that they both have POSITIVE <em>RATE OF CHANGES</em> [<em>SLOPES</em>], therefore the bottom left graph matches what we want.
** By the way, you meant
because this inequality in each graph is a <em>dashed</em><em> </em><em>line</em>. It is ALWAYS significant that you be very cautious about which inequalities to choose when graphing. Inequalities can really trip some people up, so once again, please be very careful.

The estimate the total cost to rent 3 movies and buy popcorn, a soda, and a candy bar is $18. option C
<h3>Total cost</h3>
This is the summation of all units cost of items or the results of adding all cost(fixed and variable)
Cost of movies = $3.75
= $4.00 to the nearest dollar
Cost of snacks (drinks, popcorn, candy bars) = $1.89 each
= $2.00 to the nearest dollar
Cost to rent 3 movies and buy popcorn, a soda, and a candy bar.
Total cost = (Cost of movies × number of movies) + cost of popcorn + cost of soda + cost of candy bar
= (4 × 3) + 2 + 2 + 2
= 12 + 2 + 2 + 2
= $18
Therefore, the estimate the total cost to rent 3 movies and buy popcorn, a soda, and a candy bar is $18. option C
