Answer:
see below
Step-by-step explanation:
5x - 6y = 21
Let x = 0 and solve for y to find the y intercept
-6y = 21
Divide by -6
y = 21/-6 = -7/2
The y intercept is (0,-7/2)
5x - 6y = 21
Let y = 0 and solve for x to find the x intercept
5x = 21
Divide by 5
y = 21/5 = 21/5
The x intercept is (21/5,0)
Answer:
z = 28
Step-by-step explanation:
Let's try this first:
6 = something - 1
Something = 7
Next:
We know that "something" is 1/4z
1/4z = 7
Divide both sides by 1/4 to isolate z
z = 28
Hope this helps :)
Have an awesome day!!
A) Tonya bought 3 games at X price, so 3X would be total amount.
B) Tony's cost was 0.50 less than X, so x-0.50, he bought 4 games, so he spent 4(x-0.50).
C) Set those to equal to solve for x:
3x = 4(x-0.50)
D) Solve:
3x = 4(x-0.50)
Distribute:
3x = 4x - 2
Subtract 4x from both sides:
-X = -2
Multiply both sides by -1:
X = 2
E) Since X is the amount Tonya paid per game, Tony paid X - 0.50, so Tony paid 2 - 0.50 = $1.50 per game.
Check:
Tonya: 3x = 3(2) = $6 total
Tony: 4(x-0.50) = 4(2.00 - 0.50) = 4(1.50) = $6 total
