You can’t solve this unless you have a number to plug in for y
Answer:
y = 12x + 8
Step-by-step explanation:
1. 3x - 1/4y = -2
Subtract 3x from both sides
2. -1/4y = -2 - 3x
The equation is in standard form.
3. -1/4y = -3x - 3
Multiply both sides by -4
4. Check photo for step 4
Divide by -1/4 = -0.25 undoes the multiplication -1/4 = -0.25
5. y = (-3x-2) / (-1/4)
Divide -2 - 3x by -1/4 = -0.25 by multiplying -2 - 3x by the reciprocal of -1/4 = -0.25
y = 12x + 8
5. complementary angles = 90°
90 - 40 = 50
50°
6. supplementary angles = 180°
180 - 40 = 140
140°
The correct answer is ∠Y = 75°
because
45°∠A ∼ ∠X
∠B ∼ ∠Y = 75°
60°∠C ∼ ∠Z
45 + 60 = 105
180 -105 = 75
Answer:
45
Step-by-step explanation:
plug in 3 where the xs are
2(3)(6(3)-5(3))+(3)^2(5(3)-4(3)=45
2(3)=6
6(3)=18
-5(3)=15
(3)^2=9
5(3)=15
-4(3)=-12
