Answer:
y=-2/3x
Step-by-step explanation:
if you use the graphing calculator, the y intercept of the equation is 0 therefore y=mx
m=-2/3
the slope intercept equation is y=-2/3x
"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)
That's answer.
2250 + 6x = 16x
2250 = 16x - 6x
2250 = 10x
2250/10 = x
225 = x <=== they must sell 225 cameras to equal daily costs
if they increase production by 50.......x = 225 + 50 = 275
16(275) - 6(275) - 2250 = 4400 - 1650 - 2250 = 4400 - 3900 = 500.
Their daily profit would be $500.
1192.64-819.73 is 372.91
so... if we take 1192.64 to be the 100%, how much is 372.91 in percentage then?
Answer:
1.75 feet
Step-by-step explanation:
48 ÷ 2 = 14
14 ÷ 2 = 7
7 ÷ 2 = 3.5
3.5 ÷ 2 = 1.75
