Answer:

It's y = (5)(0.2)^x

_____________

Step-by-step explanation:

Exponential functions have a standard form of ab^x

Where a is the starting value, and b is the exponential growth or decay.

Because the numbers are getting smaller and smaller, it is a decay so b must be less than one.

We can eliminate the first choice because when x is 1, y is 1. If this where the equation we would get (5) (1/2) ^ 1 = 5 × 1/2 = 2.5 ≠ 1.

So the answer must be the second choice.

Harriet earns the same amount of money each day. Her gross pay at the end of 7 work days is 35h + 56 dollars. Which expression r
Aleks [24]

Answer:

<em>The expression that represents her gross pay each day will be:  (5h+8) dollars.</em>

Step-by-step explanation:

Suppose, Harriet's gross pay each day = x

So, her total gross pay for 7 work days =7*x= 7x

Given that, her gross pay at the end of 7 work days is (35h + 56) dollars.

So, the equation will be.......

7x= 35h+56 \\ \\ x=\frac{35h+56}{7}\\ \\ x=\frac{35h}{7}+\frac{56}{7}\\ \\ x=5h+8

Thus, the expression that represents her gross pay each day will be:  (5h+8) dollars.

Through: (4, -3), perp. to y=-2x + 1
larisa86 [58]

Step-by-step explanation:

y = -2x + 1. => Slope = -2

Then the perpendicular line will have a slope of -1/(-2) = 0.5.

We have y = 0.5x + c.

When x = 4, y = -3.

=> (-3) = 0.5(4) + c, c = -5.

Hence the answer is y = 0.5x - 5. (C)

three student share a townhouse their electric bill for october was 3.87 less than the september bill. the total of both bills i
leva [86]

Answer: 40.27

Step-by-step explanation:

Let their September bill be x

Therefore, the October bill will be = x - 3.87.

Therefore, the addition of both bills will be:

x + (x - 3.87) = 237.75

x + x - 3.87 = 237.75

2x - 3.87 = 237.75

2x = 237.75 + 3.87

2x = 241.62

x = 241.62/2

x = 120.81

Therefore, September bill was 120.81

Since the 3 students share the bull equally, the amount owed by each will be:

= 120.81 / 3

= 40.27

Each person owes 40.27
