Please try leaving out the "I'm so bad at math" part. It doesn't help.
The given inequality is <span>4x + y > −6. Because of the > symbol, we must use a dashed line, not a solid one. Let's solve this for y: y > -4x - 6.
This (dashed) line has a slope of -4 and a y-intercept of (0,-6).
Plot (0,-6). Then, with your pencil pt. on that, move 1 unit to the right and then 4 units down. Plot a new point there, at (1, -10). Draw your dashed line thru those 2 pts. Then, because we have y > -4x - 6, shade the area ABOVE this line. Done.</span>
Answer:
(24x+9)yd
153yd
Step-by-step explanation:
The perimeter is the sum of all the sides, so put all the sides together.
(7x+3)+(6x+3)+(6x+3)+(5x)
7x+6x+6x+5x+3+3+3
24x+9
IF x=6:
(24(6)+9)yd
(144+9)yd
153yd

Answer: Choice B
Coffee Brand A is a better buy because its unit rate is $0.44 per ounce
=======================================================
Explanation:
Brand A is sold for $6.99 per pound, which is the same as saying $6.99 per 16 ounces. The unit rate is 6.99/16 = 0.436875 = 0.44 dollars per ounce
Brand B is sold for $5.69 for 12 ounces. The unit rate is 5.69/12 = 0.47416 = 0.47 dollars per ounce
Brand A is cheaper per ounce compared to brand B.
------------------
Here's another way we can look at it
Brand A is $6.99 per 16 ounces. We can set up the equation below
6.99 dollars = 16 ounces
then divide both sides by 16 to turn "16 ounces" into "1 ounce"
So,
6.99 dollars = 16 ounces
6.99/16 dollars = 16/16 ounces
0.436875 dollars = 1 ounce
0.44 dollars = 1 ounce
is the unit rate for brand A.
Similar steps would happen with brand B as well.
