2x - 3y = -2 ⇒ 4x - 6y = -4
4x + y = 24 ⇒ <u>4x + y = 24</u>
<u>-7y</u> = <u>-28</u>
-7 -7
y = 4
2x - 3(4) = -2
2x - 12 = -2
<u> +12 +12</u>
<u>2x</u> = <u>12</u>
2 2
x = 6
(x, y) = (6, 4)
Answer:
y = (4/3)x
Step-by-step explanation:
You have to find the y-intercept, b. Do this by substituting in the x and y values into the equation:
12 = (4/3)(9) + b
12 = 12 + b
b = 0
So, y = (4/3)x
Hope that helps! :D
Not a function.
It's conic section parabola. It's just a relation.
Step-by-step explanation:
The turning point of a quadratic function is equidistant from both x-intercepts (if they exist)
Since they do exist in this question, 3 + k = 2(0.5), 3 + k = 1, k = -2.
Okay so every triangle will have 3 angles that add to 180 degrees. You are given that A=65 which means that B + C will have to add to 115. You are given that B= (3x-10) and C=2x, plug this into B+C=115. So
3x-10+2x=115, isolate x, 5x=125, divide both sides by 5 and you get that x=25. This makes B=65, and C=50. Just to check, if you add these together you get 180 degrees.
