Solve: 3 = -2v - V V=

Y_Kistochka [10]

Answer:

V = −1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3=−2v−v

3=−2v+−v

3=(−2v+−v)(Combine Like Terms)

3=−3v

Step 2: Flip the equation.

−3v=3

Step 3: Divide both sides by -3.

−3v = 3

-3 -3

v=−1

M*(x+y)+4y/(x^2-xy-y^2)=(x+2y)/(x^2-xy-Y^2),find the value of M

dybincka [34]

Answer: M = $\frac{x-2y}{x+y}$

Step-by-step explanation:

$\frac{M(x+y)+4y}{x^{2}-xy-y^{2} } =\frac{(x+2y)}{x^{2} -xy-y^{2} }$

M (x + y) + 4y = x + 2y (Multiply $x^{2} - xy-y^{2}$ in both sides)

M (x + y) = x + 2y - 4y

M (x + y) = x - 2y (Divide (x+y) from both sides)

M = $\frac{x-2y}{x+y}$

I need help solving this question with explaining please ANSWER ASAP!!!!!!!!!

x = 85 degrees and

y = 45 degrees.

Step-by-step explanation:

Step 1:

The angle for a straight line is 180°. The sum of the angles in a triangle is 180°. These two statements are required to solve this problem.

The angles of x° and 95° are on a single straight line.

So $x^{\circ} + 95^{\circ} = 180^{\circ}.$

$x^{\circ} = 180^{\circ} - 95^{\circ} = 85^{\circ} .$

So the angle of x is 85°.

Step 2:

The sum of the angles in a triangle is 180°.

So $50^{\circ} + x^{\circ} + y^{\circ} =180^{\circ}.$

$50^{\circ} + 85^{\circ} + y^{\circ} =180^{\circ}.$

$y^{\circ} =180^{\circ} - 135^{\circ}, y = 45 ^{\circ}.$

So the angle of y is 45°.

The value of x varies directly with the value of y, and when x=20, y=18. What is the value of “k”, the constant of proportionali

stealth61 [152]

Answer:

In this case, y=30 and x=6, so 30=k*5<=> k=30/6=5.

Step-by-step explanation:

The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.

I need help with slope!!!

Dmitriy789 [7]

Answer:

$\frac{4}{3}$

Step-by-step explanation:

If you start at G you go up 4 spaces then right 3 spaces. The the same exact thing which leaves you with the slope rise (over) run so your answer would be $\frac{4}{3}$ .
