Answer: -3
Step by Step Explanation: This type of equation is called slope-intercept form, y=mx+b; the slope is m, so the slope is -3
Answer:
Amount in 4% account: $550
Step-by-step explanation:
Use simple interest formula
where
I = interest
P = principal
r = rate (as decimal)
t = time.
<u>4% account:</u>

then

<u>5% account:</u>

then

You have earned $69.50 in total, so

Amount in 4% account: $550
Amount in 5% account: $950
Answer:
A.
Step-by-step explanation:
Answer:
<h2>

</h2>
Step-by-step explanation:


Solve the equation for y by moving 'x' to R.H.S and changing its sign


Substitute the given value of y into the equation 5x + y = 28

Solve the equation for x
Collect like terms

Move constant to R.H.S and change its sign

Subtract the numbers

Divide both sides of the equation by 4

Calculate

Reduce the numbers with 2

Now, substitute the given value of x into the equation y = 2 - x

Solve the equation for y

The possible solution of the system is the ordered pair ( x , y )
<h2>

</h2>
-------------------------------------------------------------
Let's check if the given ordered pair is the solution of the system of equation:
plug the value of x and y in both equation


Simplify the equalities


Since , all of the equalities are true, the ordered pair is the solution of the system.

Hope this helps....
