Answer:
The graph in the attached figure
Step-by-step explanation:
we have
Remember that the denominator cannot be equal to zero
so
The value of x cannot be equal to x=-2
<em>Simplify the numerator</em>
----> by difference of squares
substitute
simplify
The domain is all real numbers except the value of x=-2
The y-intercept is the point (0,-6) ---> value of y when the value of x is equal to zero)
The x-intercept is the point (2,0) ---> value of x when the value of y is equal to zero)
therefore
The graph in the attached figure
For this question we will use the following relations.
100 centimeters=1 meter (or 1 centimeter= 0.01 meter)
10 millimeter=1 centimeter (or 1 mm=0.1 cm)
60 minutes = 1 hour (or 1 min=
hour)
Now, Jackson's speed is 1350 meters per hour. This can be converted to cm per minute as follows:
...Equation 1
Likewise, Jonah's swim speed in cm/min can be calculated as:
...Equation 2
As we can see clearly after comparing Equation 1 and Equation 2, Jonah's swim speed of 7500 cm/min is faster than that of Jackson.
Thus, option B is correct.
Answer:
0.45
Step-by-step explanation:
Percent is per 100, so the fraction is 45/100.
The decimal is the numerator, but you need to swoop 2 times.
Therefore, the answer is 0.45.
T° Fahrenheit=t°( C°)×1.8+32
a)35° C=95° F
b)500° C=932° F
c)10° C=50° F
d)55° C=131° F
Answer:
I agree with you that step 5 doesn't make sense.
In step 4 he had accurately determined that there were 216 British and Indian stamps.
B = number of British stamps
N = number of Indian stamps (using N because "I" looks too much like a "1")
B + N = 216
3/5B = N
substitute for N:
B + 3/5B = 216
8/5B = 216
divide both sides of the equation by 8:
1/5B = 27
multiply both sides of the equation by 5:
B = 135
N = 81
It appears that step 5 is missing the "multiply by 5".
