Answer:
y=-6x-57 is your answer.
Step-by-step explanation:
You will use this equation:
y-y1=m(x-x1). The y1 is -2 and the x1 is -9.
y-(-3)=-6(x-(-9)). You will the distribute the -6 into the x and the -9.
y+3=-6x-54. You will then subtract 3 to both sides.
y=-6x-57 is your answer.

Answer: The mat is 4.33 ft high off the ground.
Step-by-step explanation:
Since we have given that
Angle of elevation with the first triangle = 30°
Angle of elevation with the second triangle = 60°
Length at which gymnastics mat extends across the floor = 5 feet
so, As shown in the figure:
We need to find the height of the mat off the ground.
If CD = 5 ft,
Let, AB = y, DC = x.
In Δ ABC,

Similarly, in Δ ACD,

Hence, the mat is 4.33 ft high off the ground.

Answer: 640c - 6.25s - 8.75g</h3>
===============================================
Work Shown:
s = number of small cups
g = number of large cups
c = number of coolers
----------
1 cooler = 640 fluid ounces
c coolers = 640c fluid ounces
1 small cup = 6.25 fluid ounces
s small cups = 6.25s fluid ounces
1 large cup = 8.75 fluid ounces
g large cups = 8.75g fluid ounces
----------
T = total amount of water poured
T = (amount from small cups) + (amount from large cups)
T = 6.25s+8.75g
L = amount of water left
L = (original total amount of water) - (amount of water poured out)
L = 640c - T
L = 640c - (6.25s+8.75g)
L = 640c - 6.25s - 8.75g
