Answer:

y = -2x + 21

Step-by-step explanation:

use point intercept form: y = mx + b where m is the slope and b is the y intercept

to find the y intercept, b, plug in values into equation and solve for b

11 = (-2) (5) + b

b = 21

then plug into the equation the slope and intercept!

Natalle is a softball coach. She has a pitching private lesson with Kasey. Kasey's mom pays Natalle $11 per hour plus a $6 tip.
kirill [66]
11t\text{ + 6 = 39}

where t is the number of hours worked by Natalle

Here, we want to write an equation that will represent the given scenario

Let the number of hours for which she earned the pay be t

From the question, she earns $11 per hour

So for t hours, the amount earned excluding the tip will be;

(11\times t)\text{ = \$11t}

Now, let us add the tip and equate to the total amount earned

We have this as;

11t\text{ + 6 = 39}

What is the value of y in the solution to the system of equations?
FinnZ [79.3K]
You can either multiply both equation by -2 or multiply both equations by 3 because when you multiply -2 you can eliminate x term
1. -2(x) -2(y) = -2(1) -> -2x -2y=-2

So far
-2x-2y=-2
+
2x-3y= -30

(-2x+2x) + (-2y-3y)= -32
0-5y = -32
Y= 32/5
Substitute y with 32/5

X+ 32/5= 1
Minus -32/5 over
X= -27/5

I don’t know why my answer doesn’t match with those answers above. I also checked by calculator. Did you write the question wrong?
