Let us say first number is x.

Let us say second number is y.

We are given that:

The difference of the two numbers is 2.

x-y=2

x=2+y.................(1)

We are also given that:

product of the numbers is 41.25

x*y=41.25............(2)

Plugging the value of x from equation (1) in (2)

(2+y)*y=41.25

2y+y^{2}=41.25

On solving we will get,

y=5.5 and y=-7.5

So if y=5.5,

x= 2+y = 7.5

Answer : The first number is 7.5 and the second number is 5.5

If ΔABC is reflected across the y-axis, what are the resulting coordinates for points A', B', and C'
Sever21 [200]

Answer:

Step-by-step explanation:

Reflection across the y axis changes the x value.

Reflection across the x axis changes the y value.

This is counterintuitive, but it is correct.

A'

(-1,6)

B'

(-2,1)

C'

(-5,2)

Do you see what happened. All the values for x become - values because you are moving an equal distance in the -x direction

HELP!!! Lucas deposits $250,000 into two investment accounts. Over a year, the first account
prohojiy [21]

The amount deposited in the account that earns 3.6% interest is $57,600 and the amount  deposited in the account that earns 2.1% interest is $192,400

The first step is to determine the amount of interest he earned in total over a year

Interest = Amount in the account - amount deposited

$256,114 -  $250,000 = $6,114

The second step is to formulate two set of equations and use simultaneous equation to solve the question

a + b = $250,000 equation 1

0.036a + 0.021b = $6,114 equation 2

Where a represent amount deposited in the account that earns 3.6% interest

b  represent amount deposited in the account that earns 2,1% interest

Multiply equation 1 by 0.036

0.036a + 0.036b = 9000 equation 3

Subtract equation 2 from 3

2886 = 0.015b

divide both sides of the equation by 0.015

b = $192,400

Substitute for b in equation 1

a + 192,400 = 250,000

a = 250,000 - 192400

a = $57,600
