Answer:
The common ratio is 3
Step-by-step explanation:
To determine the common ratio, we take the second term and divide by the first term
9/3 =3
To verify this we take the third term and divide by the second term
27/9 = 3
Answer:
m = 3 and c = - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 2 ← is in slope- intercept form
with m = 3
• Parallel lines have equal slopes, thus
y = 3x + c ← is the partial equation of the parallel line
To find c substitute (1, 2) into the partial equation
2 = 3 + c ⇒ c = 2 - 3 = - 1
y = 3x - 1 ← equation of parallel line
with m = 3 and c = - 1
Answer : y= -3x-2 Hope this helped!
Answer:
<em>Joshua is traveling at a faster rate</em>
Step-by-step explanation:
2 hours = 120 minutes (To have the same units of measurement)
30 minutes / 7 miles = 30 ÷ 7 = 4.285 = 4.3 (Brook)
120 minutes / 25 miles = 120 ÷ 25 = 4.8 (Joshua)
To begin, you would have to convert 2 hours into minutes (2 x 60), which gives you 120 minutes. Then divide your minutes by miles for both Brook and Joshua. Then once you've done that, you can then compare the travel rate of both and determine that Joshua is traveling faster.
