Answer:

m = 84/31

Step 1: Simplify

\frac{3(m-1)-4}{5} =\frac{8-(2m+1)}{7}

\frac{3(m-1)-4}{5}=\frac{8-(2m+1)}{7}

Step 2: Cross multiply

7*\frac{3(m-1)-4}{5}=\frac{8-(2m+1)}{7}*5

21m-49=-10+35

Step 3: Add 10m to both sides

21m-49+10m=-10m+35+10m

31m-49=35

Step 4: Add 49 to both sides

31m-49+49=35+49

31m=84

Step 5: Divide both sides by 31

\frac{31m}{31} =\frac{84}{31}

m=\frac{84}{31}

3x+7=13 what's the answer?
Dafna11 [192]
The first step to this is to subtract 7 from both sides. The +7 and -7 cancel each other out leaving you with 3x=6 then divide by 3 on each side giving you x=2.

The equation x2 − xy + y2 = 3 represents a "rotated ellipse," that is, an ellipse whose axes are not parallel to the coordinate
Setler [38]

Answer:

the points where the ellipse crosses the x- axis are (1.73, 0) and (-1.73, 0)

Step-by-step explanation:

To find the points at which a graphic crosses the x-axis we need to find the values for x where y = 0.

Therefore, in the equation x²- xy + y² = 3 we are going to make y = 0 and solve for x

x² - xy + y² = 3

x²- x(0) + (0)² = 3

x² = 3

x = ±√3

x₁ = 1.73 and x₂ = -1.73

Therefore, the points where the ellipse crosses the x- axis are (1.73, 0) and (-1.73, 0)
