Write the equation of a line in point-slope form that is parallel to the line y=2x-5 and goes through the point (-1,4)

Which equation represents a line that passes through (2, –left-parenthesis 2, negative StartFraction one-half EndFraction right-parenthesis.) and has a slope of 3?

y – 2 = 3(x + y minus 3 equals 2 left-parenthesis x plus StartFraction one-half EndFraction right-parenthesis.)
y – 3 = 2(x + y minus 3 equals 2 left-parenthesis x plus StartFraction one-half EndFraction right-parenthesis.)
y + y plus StartFraction one-half EndFraction equals 3 left-parenthesis x minus 2 right-parenthesis. = 3(x – 2)
y + y plus StartFraction one-half EndFraction equals 2 left-parenthesis x minus 3 right-parenthesis. = 2(x – 3)

In a petri dish, a certain type of bacterium doubles in number every 45 minutes. There were originally 32, or 2^5 bacteria in the dish. After 180 minutes, the number of bacteria has doubled 4 times, multiplying by 2^4. Now the population of bacteria is 2^5 • 2^4. Expressed as a power, how many bacteria are in the petri dish after 180 minutes?

A.) 2^4
B.) 2^20
C.) 4^9
D.) 2^9​

A boat rental company charges $1,200 per week to rent a boat, plus an additional $215
each time the customer refills the boat's gas tank. Which equation represents the total cost
c of renting a boat for 1 week and refilling the gas tank g times?
C = (1.200 215g) x 7
C = 1.200 2159
C =1.200 x 7 - 2159
C =11.200- 21519

In this formula, C represents the total charge for babysitting and I represents the
number of hours the child is kept. How much should Joe pay if his child is at the
babysitting service for 3 hours?
C = $5.25 + $2.50H
