Answer:
anything greater than 3/5
Step-by-step explanation:
equation: x is greater than 3/5
Answer:
width=4
length=18
Step-by-step explanation:
length-6=3width
length=3width+6
also:
perimeter of the rectangle=2(length+width)
44/2=width+length
22=width+length
now put the length we found in the 1st equation, in 22=width+length
=>22=width+3width+6
22-6=4width
width=4
now do the exact same thing with one of these equations:
22=width+length
length=3width+6
I'd do it with the 1st one:
22=4+length
22-4= length
length=18
Answer:
Yes that is correct. B is correct.
Step-by-step explanation:
When you plug 0 in for x, the result is 3.
When you plug 1 in for x, the result becomes 1.
The equation matches up correctly.
f(x) = -2x + 3

Answer:
Lower bound = 5.2
Upper bound = 5.4
Step-by-step explanation:
If a= 4.2 to (1dp):
Upper bound = 4.2 + 0.05 = 4.25
Lower bound = 4.2 - 0.05 = 4.15
If b = 18 (to the nearest whole number)
Upper bound = 18 + 0.5 = 18.5
Lower bound = 18 - 0.5 = 17.5
Therefore:
Lower bound of ((a+b)/a) = ((4.15 + 17.5) / 4.15) = 5.2 to 1 decimal place
Upper bound of ((a+b)/a) = ((4.25 + 18.5) / 4.25) = 5.4 to 1 decimal place
The upper and lower bound are calculated to one decimal place.
Answer:
Step-by-step explanation:
BC = 15 cm
3x = 15
x = 15/3 = 5
AB =4x = 4*5 = 20 cm
Pythagorean theorem,
AC² = AB² + BC²
= 20² + 15 ²
= 400 + 225
= 625
AC = √625 = 25 cm
AC = 25 cm
