2 answers:

7 0

Step 1: Rewrite the equation

3y+x=12

Step 2: To get y alone on the left side, subtract x on both sides

3y+x=12
-x -x
______
3y=-x+12

Step 3 (final step): To get y alone, divide each number by 3

3y = -x +12
/3 /3 /3
________
y=-1/3x+4

Final answer: y=-1/3x+4

Hope this helps :)

Which set of points includes all of the solutions for y = negative three halves times x plus two? line going through 0 comma 2 a

Answer:

$(x,-\frac{3}{2} x+2)$

Step-by-step explanation:

For $y= \frac{-3}{2} x+2$ the set of points that include all solutions are $(x,y)$ such that $y= \frac{-3}{2} x+2$ ; then we have $(x,y)=(x,\frac{-3}{2} x+2)$ .

What is important to stress here is that $(x,-\frac{3}{2} x+2)$ represents all of the solutions, while other points that we are given represent one solution (for example, point (2,-1) is just one solution)

Find the discriminant of 3x^2-10x=-2

Oksanka [162]

Answer:

Step-by-step explanation:

given a quadratic equation in standard form : ax² + bx + c = 0 : a ≠ 0

then the discriminant is Δ = b² - 4ac

given 3x² - 10x = - 2 ( add 2 to both sides )

3x² - 10x + 2 = 0 ← in standard form

with a = 3, b = - 10 and c = 2

b² - 4ac = (- 10)² - (4 × 3 × 2) = 100 - 24 = 76
