Karan needs to choose between two gym plans. He can either pay a $150 joining fee and a $10 monthly fee, or he can pay a $50 joi
Ierofanga [76]

Let  x be the month on which the fee for two plans are equal.

Therefore,

150 + 10x = 50 + 30x

10x - 30x = 50 - 150

-20x = -100

x = 5

Cumulative cost = 150 + 10(5)

                           = 150 + 50

                           = 200

Hence, Karan will pay a cumulative cost of $200 dollars with either plan to go to the gym for 5 months.

At a supermarket the price of a carton of blueberries varies directly with its weight. A carton that weighs 0.5 lb cost $4.25. W
IRISSAK [1]
It is $6.375.
0.5lb:$4.25
0.75lb:$6.375
This is because 0.75lb is 1.5 times greater than 0.5, so you do 4.25*1.5, which is $6.375

Guys the answer guys plz​
ryzh [129]

Answer:

No

Step-by-step explanation:

The definition of a prime number is a number that only has factors of 1 and itself.  So there are only 2 factors.  

4 has 3 factors: 1, 2, and 4.  It has factors of 1 and itself (4), but also has an extra factor (2), so 4 is not a prime number

Find the the equation of the line passing through the points (3,3) and (4, 5)
Nostrana [21]

Answer:

y = 2x - 3

Step-by-step explanation:

Given:

(3, 3) and (4, 5)

Solve:

Find the slope (m) between the two points:

m = (y2 - y1)/(y2 - 1)

(x1, y1) = (3, 3)

(x2, y2) = (4, 5)

m = (5 - 3)/(4 - 3)

= 2/1

m = 2

Slope-intercept form (y = mx + a):

y = 2x + a

To find a, plug in one of the points into the equation:

3 = 2(3) + a

3 = 6 + a

3 - 6 = a

a = -3

y = 2x - 3
