You could do this with fractions. I'll do decimals later.
d = 3/4 mile
t = 2/3 hour
r = ????
r = 3/4 // 2/3 Invert and multiply the denominator
r = 3/4 * 3/2 = 9/8 = 1 1/8
If your calculator handles fractions, you can use it to do this. If not you can change this to a decimal.
d = 3/4 = 0.75 miles
t = 2/3 hour = 0.666666666 hours.
r = ???
d = r*t
r = d/t
r = 0.75 / 0.66666667
r = 1.125 miles / hour
which gives you exactly the same answer 1.125 = 1 1/8
A works because it due to laws of exponents
B works because (3*3)^x= (9)^x through simple multiplication
C does not work because
D does not work because
E does not work because
F does not work because
What you do is you take the denominator and you divide it into the numerator.
The equation shown on the graph is y = 2x + 3. The correct answer is C. y = 2x +3
<h3>Equation of a line </h3>
From the question, we are to determine the equation that represent the given line
To determine the equation, we will pick two points on the line and determine the equation of the line
Picking the points (0, 3) and (3, 9)
Using the formula for the finding the equation of a line with two given points
(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁)
x₁ = 0
y₁ = 3
x₂ = 3
y₂ = 9
Then,
(y - 3)/(x - 0) = (9 - 3)/(3 - 0)
(y - 3)/x= 6/3
(y - 3)/x= 2
y - 3 = 2x
y = 2x + 3
Hence, the equation shown on the graph is y = 2x + 3. The correct answer is C. y = 2x +3
