X=-1 and y=3

To solve this, because y is equal to 2x+5, you can substitute 2x+5 into the bottom equation for y.

You now have 3x - (2x + 5) =-6

This can be solved like a normal equation. Multiply each term in the parenthesis by -1.

3x - 2x - 5 = -6

Subtract 2x from 3x

x - 5 = -6

Add 5 to both sides

x=-1

Now you can solve for y by plugging -1 in for x in either equation. Im going to use the top one.

y= 2(-1)+5
y= -2+5
y=3

You can check your answer by plugging in the values for x and y into both equations and making sure both sides equal each other.

Martha bought 3 apples and 6 oranges She had $10 in her wallet which was enough money for the purchase wrie a asystem of equatio

meriva

3x + 6y = 10 is the equation to determine of an apple x and the price of an orange y

Solution:

Let the price of each apple = $ x

Let the price of each orange = $ y

Martha bought 3 apples and 6 oranges

She had $10 in her wallet which was enough money for the purchase

Thus the equation is:

Total amount = 3 apples(price of each apple) + 6 oranges(price of each orange)

Thus we get,

$10 = 3x + 6y\\\\3x + 6y = 10$

Thus the equation is found

What is the horizontal asymptote??? Math 3!! 10 points HELP NEEDED

Ymorist [56]

Answer:

no horizontal asymptote

Step-by-step explanation:

When the degree of the numerator > degree of the denominator there is no horizontal asymptote but there is a slant asymptote.

Dividing the numerator by the denominator gives

$\frac{x^2-x-6}{x+4}$ = x - 5 + $\frac{14}{x+4}$

There is a slant asymptote with equation y = x - 5
