Answer:
Step-by-step explanation:
x-2(4x-3)=30
x-8x+6=30
-7x=30-6
-7x=24
x=-24/7 maybe it is a mistake in the statement of the problem
Answer:
By changing 0.65 miles into fraction we got 65/100 and it's simplest form is 13/20 .
Answer:
10/14
Step-by-step explanation:
substitute x in equation 2
y= 2(10) -6
y= 20 - 6
y= 14
substitute y in equation 2
14 = 2x - 6
-2x= -6-14
-2x= -20
divide both sides by -2
-20/-2
x= 10
y= 14, x= 10
0.75 * 15% = 0.1125
0.75 + 0.1125 = 0.8625 yards
Not sure if your 1125 yards in the question was correct, but she needed to cut 0.8625 yards to have 15% over the 0.75 she needs.
The shape of the graph is very similar to a natural logarithm, which is ln(x). ln(x) has an asymptote at x=0. Shift the graph 3 units to the left and you have the graph of ln(x+3), which has an asymptote at x= -3. Also, when x=0, ln(x+3) is about 1. I think ln(x+3) is the answer. Check this online graph to see if this matches:
