First, isolate x in x-4y=11 because 1 is x's coefficient.
x-4y=11
x=11+4y
Now, substitute 4y+11 for x in 5x-7y=-10.
5x-7y=-10
5(4y+11)-7y=-10
20y+55-7y=-10
Add all coefficients.
13y+55=-10
Isolate y by subtracting 55 from both sides.
13y+55=-10
13y=-10-55
13y=-65
y=-5
Now substitute -5 for y in your first equation.
x=11+4y
x=11+4(-5)
x=11-20
x=-9
Your answer would be (-9,-5).

By the way this looks, this is a linear relationship. By marking points on a graph, I can see that Ahmad payed 30 dollars more total, and if he payed 4 dollars per movie, and 5 dollars per game, then it adds up for the first part but not the second. We would have to have decimal points, but graphing does not work for this. It's a start
Answer:
B. 4/3
Step-by-step explanation:
Tan is Opposite over Adjacent (SOH CAH TOA), so you would have to take the opposite (36) and put it over the value of the side adjacent to X (27).
36/27 simplifies to 4/3 if you divide both the numerator and denominator by 9.
Your final answer is b (4/3)
Answer:
y=-5.5x+-5
Step-by-step explanation:
<em>the slope is -5.5</em>
<em>the y-intercept is what the y-axis is when the x-axis is zero</em>
<em>therefore the y-intercept is -5</em>
hope this helps
have a nice day!!
