At what point does a line with a slope of 34 and a y-intercept of -5 intersect a line with a slope of −14 and a y-intercept of 3
maw [93]
Set them into slope-intercept forms of equations then set those equations equal to each other and solve for x and y.  y = 34x - 5 and y = -14x+3.  Set those equal to each other, solve for x to get x = 1/6.  Sub in that x value to get y = 2/3.  The point where they intersect is the solution of the system; in other words, where on both lines we have the exact same (x, y) value.

5 1/3 + x = 2 1/2. Use least common denominator or easiest common denominator. Please work out
julia-pushkina [17]

Answer:

The answer is x = -17/6.

Step-by-step explanation:

Given:

5 1/3 + x = 2 1/2 . Using least common denominator.

Now, to solve the equation:

5\frac{1}{3}+x=2\frac{1}{2}

=\frac{16}{3} +x=\frac{5}{2}

Subtracting both sides from 16/3 we get:

x=\frac{5}{2}- \frac{16}{3}

Now, the least common denominator of 2 and 3 is 6.

So, we using this we calculate:

x=\frac{5\times 3-16\times 2}{6}

x=\frac{15-32}{6}

x=\frac{-17}{6}

Therefore, the answer is x = -17/6.
