The zeroes (or 'roots') of a function occur when it crosses the x-axis, the line
y
=
0
. Let
x
2
−
25
=
0
. Rearranging
x
2
=
25
→
x
=
±
√
25
=
±
5
. The roots are
+
5
and
−
5
.
When x=-2, then the value of y is 0
Answer: $1.75
Step-by-step explanation:
Each pint of fruit = $2.85
7 pints of fruit = 2.85 x 7 = 19.95
5 pints of veggies will cost
28.70 - 19.95 = 8.75
Each pint of veggies = 8.75 / 5 = 1.75
30 × 125 = 3750
125 bins can hold up to 3750 toys
3756 - 3750 = 6
6 toys will be left over
Answer:
41.67
Step-by-step explanation:
log 2x+log12=3
log (a) + log (b) = log (ab)
log (2x*12) =3
log (24x) = 3
raise each side to the power of 10
10 ^ log (24x) = 10 ^3
24x = 1000
divide by 24
24x/24 = 1000/24
x = 41.666666666......
rounding to the nearest hundredth
41.67
