Suppose you receive $100 for a graduation present, and you deposit it in a savings account. then each week thereafter, you add $

nadezda [96]

You will have $310 in your account after 42 weeks.

Step-by-step explanation:

Graduation present = $100

Amount deposited per week = $5

Let, x be the number of weeks, therefore, the function is

f(x) = 100+5x Eqn 1

We will put f(x)=310 in Eqn 1 to find number of weeks.

$310=100+5x\\310-100=5x\\210=5x\\5x=210\\$

Dividing both sides by 5

$\frac{5x}{5}=\frac{210}{5}\\x=42$

You will have $310 in your account after 42 weeks.

Lena reflected this figure across the x-axis. She writes the vertices of the image as A'(−2, 8), B'(−5, 6), C'(−8, 8), D'(−4, 2)

garik1379 [7]

Answer:

Option A) she reflected the pre-image across the y-axis

Step-by-step explanation:

we know that

When reflect a point across the the x-axis the rule of the reflection is equal to

(x,y) -----> (x,-y)

When reflect a point across the the y-axis the rule of the reflection is equal to

(x,y) -----> (-x,y)

In this problem we have

A(2,8),B(5,6),C(8,8),D(4,2)

Applying the rule of the reflection across the x-axis

The coordinates of the image would be

A'(2,-8),B'(5,-6),C'(8,-8),D'(4,-2)

Applying the rule of the reflection across the y-axis

The coordinates of the image would be

A'(-2,8),B'(-5,6),C'(-8,8),D'(-4,2)

therefore

she reflected the pre-image across the y-axis.

A company claims its washing machine produces 4000 joules of work output for every 3000 joules of work input. What would make yo

ycow [4]

Things that make me skeptical: No evidence is provided, the company also claims that its washing machine produces 4000 joules of output for ever 3000 joules of input, and there is no possible way of creating a joule output larger than the input, unless your using coils to increase electricity, but that's not what washing machines have inside of their machinery. Washing machines don't have mini Tesla coils inside their machinery!

I hope this helps!
