1. <span>In this case the two </span>equations<span> describe lines that intersect at one particular point. Clearly this point is on both lines, and therefore its coordinates (x, y) </span>will<span> satisfy the </span>equation<span> of either line. Thus the pair (x, y) is the one and only </span>solution<span> to the </span>system of equations<span>.

Answer:
89°C
Step-by-step explanation:
I think it is just a case of subtraction. Remove the °C and just treat it as 85 - -4
The answer is -10xy
(10x^2)(-5y^3)/5xy^2
=-50x^2y^3/5xy^2
=-10x^2y^3/xy^2
=-10xy
x^2/x is the same thing as X^2-1
y^3/y^2 is the same thing as Y^3-2
328 ÷ 4 = 82 mph. (unit rate)
82 x 10 = 820.
Haley can drive 820 miles in 10 hours, and drove 82 miles per hour.
hopefully this helps
I believe you are looking for the surface area.
Keep in mind B is the area of the base.
SA = LA + 2B
LA = HP
SA= HP + 2B
SA = 7.21 * 8 + 32
SA = 57.68 + 32
SA = 89.68 unit squared
