Y = 1/3 x - 10 . . . (1)
2x + y = 4 . . . . . (2)

Putting (1) into (2) gives
2x + 1/3 x - 10 = 4
7/3 x = 4 + 10 = 14
x = (3 x 14)/7 = 3 x 2 = 6
x = 6

From (1), y = 1/3 (6) - 10 = 2 - 10 = -8
y = -8

Thi equence repreent the diameter of circle ued to create an art project 2. 5 cm, 3. 1cm, 3. 7cm,4. 3cm let f(n) repreent diamet
stellarik [79]

The equation for the given sequence representing the diameter of the circle is

f(n) = f(n-1) + 0.6, where f(1) = 2.5

Given, a sequence of diameters of a circle used to create an art project

2.5 , 3.1 , 3.7 , 4.3

We have to find a sequence that represents the diameter of the given circle,

Let f(n) be representing the diameter of the circle,

Now, for n = 1

f(n) = 2.5

for n = 2

f(n) = 3.1

for n = 3

f(n) = 3.7

for n = 4

f(n) = 4.3

As, f(2) = f(1) + 0.6 and so,

So, f(n) = f(n-1) + 0.6

Hence, the equation for the given sequence representing the diameter of the circle is

f(n) = f(n-1) + 0.6, where f(1) = 2.5

Ryan the trainer has two solo workout plans that he offers his clients: Plan A and Plan B. Each client does either one or the ot
Ivahew [28]

Answer:

Both plans last for 1.25 hours (1 hour 15 minutes)

Step-by-step explanation:

Let x hours be the time needed for plan A and y hours be the time needed for plan B.

On Wednesday there were 5 clients who did Plan A and 3 who did Plan B. Thus, 5x+3y=10.

On Thursday there were 2 clients who did Plan A and 6 who did Plan B. Thus, 2x+6y=10.

Solve the sytem of two equation. Multiply the first equation by 2, the second by 5 and subtract them:

10x+6y-10x-30y=20-50,\\ \\-24y=-30,\\ \\y=\dfrac{30}{24}=\dfrac{5}{4}=1.25\ hours.

Therefore,

5x+3\cdot 1.25=10,\\ \\5x=10-3.75=6.25,\\ \\x=1.25\ hours.
