Answer: y = x
<u>Step-by-step explanation:</u>
First, find the point where 5x - 2y + 3 and 4x - 3y + 1 intersect using the Elimination Method.
5x - 2y + 3 = 0 → 3(5x - 2y + 3 = 0) → 15x - 6y + 9 = 0
4x - 3y + 1 = 0 → -2(4x - 3y + 1 = 0) → <u> -8x + 6y - 2</u> =<u> 0 </u>
7x + 7 = 0
7x = -7
x = -1
5x - 2y + 3 = 0
5(-1) - 2y + 3 = 0
-5 - 2y + 3 = 0
-2y - 2 = 0
-2y = 2
y = -1
(-1, -1)
Next, find the point where x = y and x = 3y + 4 intersect using the Substitution Method.
x = y
x = 3y + 4 → y = 3y + 4
-2y = 4
y = -2
x = y
x = -2
(-2, -2)
Now, find the line that passes through (-1, -1) and (-2, -2) using the Point-Slope formula. (x₁, y₁) = (-1, -1) and m = 1
y - y₁ = m(x - x₁)
y + 1 = 1(x + 1)
y = x
Answer:
123
Step-by-step explanation:
3 + (16 - 1)8
3 + (15)8
3 + 120
123
Answer: 175
Step-by-step explanation:
Let say
x the number of ticket at $6
y the number of ticket at $10
z the number of ticket at $12
500 total tickets were sold : x+y+z=500
the total income from ticket sales were $4.500: 6*x+10*y+12*z=4500
the combined number of $6 and $10 tickets was four times the
number of $12 tickets sold: x+y=4*z
x=175
