Casey wants to buy a gym membership. Gym A has a $150 joining fee and costs $35 per month. Gym B has no joining fee and costs $6
MariettaO [177]

Answer:

Step-by-step explanation:

Gym A has a $150 joining fee and costs $35 per month.

Assuming that Casey wants to attend for x months, the cost of using gym A will be

150 + 35 times x months. It becomes

150 + 35x

Gym B has no joining fee and costs $60 per month.

Again, assuming that Casey wants to attend for x months, the cost of using gym B will be

60 × x months = 60x

A) To determine the number of months that it will both gym memberships to be the same, we will equate them.

150 + 35x = 60x

60x - 35x = 150

25x = 150

x = 150/25 = 6

It will take 6 months for both gym memberships to be the same.

B) If Casey plans to only go to the gym for 5 months,

Plan A will cost 150 + 35×5 = $325

Plan B will cost 60 × 5 = $300

Plan B will be cheaper

a parallelogram has one angle that measures 40. what are the measures of the other three angles in the parallelogram?
KonstantinChe [14]
Since one side is 40°, you subtract that from 180.

180° - 40°= 140°.

So therefore your missing side lengths are 140, 40, and 140.

hopefully this helps

Which statement correctly describes the relationship between the graph of f(x)g(x) and g(x)=f(x−7)?
Lelu [443]
G(x) would have to be -->7 units.
The relationship between f(x) and s(x) where s(x)=af(x-b)+z is that g(x) is f(x) stretched by the reciprocal of a, b is the liar (all x values go up if b goes down and visa versa), and it moves up z units.

krek1111 [17]
100 muffins, and 2 in each packages. Therefore, there are 50 packages. However, at the end, there are 12 left, so there must have been 6 packages left. (12/2) 50-6=44. 44*2=88 so 88 muffins were bought.

For all parts of this question, use the function y + 2 = 3(x + 4)
vekshin1

i would start by simplifying the equation to get y by itself, you don't need to do this, but it makes it a little easier

y + 2 = 3 ( x + 4) distribute the 3 through the parenthesis

y + 2 = 3x + 12. subtract 2 from both sides

y = 3x +10

now to fill in the chart simply plug in the value of x to see what value of y it produces

y = 3(-2) +10

y = -6+10

y = 4

(-2,4)

y = 3(0) + 10

y = 0 + 10

y = 10

(0,10)

y = 3(2)+10

y = 6 + 10

y = 16

(2,16)

y = 3(4) + 10

y = 12 + 10

y = 22

(4,22)
