The value of x and y is y= 3/4 and x= -1/2

<h3>What is equation?</h3>

An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.

Given equations:

2x+8y=5........(1)

24x-4y=-15...........(2)

Multiply equation (1) by 12, we get

24x + 96y = 60.....(3)

From (2) and (3), we get

-4y-96y= -15-60

-100 y= -75

y= -75/-100

y= 3/4

and 2x+8y=5

2x + 8 (3/4) =5

2x + 6 = 5

2x= -1

x= -1/2

Why does your monthly payment go up if you reduce your down payment
charle [14.2K]

Answer:

When you buy expensive items with a loan, you often need to make a down payment to cover a portion of the purchase price. That initial payment is often critical for getting approved, and it can affect your borrowing costs throughout the life of your loan. As a result, it’s wise to understand how down payments work so you can choose the right down payment amount.

21x-5=7+17x <br> Write it down step by step please
Nat2105 [25]

Answer: x=3

Step-by-step explanation: Step 1: Simplify both sides of the equation.

21x−5=7+17x

21x+−5=7+17x

21x−5=17x+7

Step 2: Subtract 17x from both sides.

21x−5−17x=17x+7−17x

4x−5=7

Step 3: Add 5 to both sides.

4x−5+5=7+5

4x=12

Step 4: Divide both sides by 4.

\frac{4x}{4} = \frac{12}{4}

So Final Answer: <u>x=3</u>

What is the derivative of g(x)=e^(x^2+2x)+3x
UNO [17]
Ok first we can split it in two : e^{x^2+2x} and 3x.

The derivative of 3x is 3.

For the first part, we use the chain rule : [f(g(x))]'=g'(x)f'(g(x)) hence (e^{x^2+2x})'=(x^2+2x)'e^{x^2+2x} (since the derivative of the exponential is itself) hence g'(x)=(2x+2)e^{x^2+2x}+3
