Answer:

x=-½

x=5

Step-by-step explanation:

2x²-5x-10=4x-5

2x²-5x-10-4x+5=0

2x²-9x-5=0

2x²+x-10x-5=0

x(2x+1)-5(2x+1)=0

(2x+1)(x-5)=0

2x+1=0

2x=-1

x=-1/2

x-5=0

x=5

The most confused that i have been
Trava [24]

Answer:

(-5, -3)

Step-by-step explanation:

To graph the two equations, you can look at two things, the slope and the y-intercept.

The two equations are in slope-intercept form, y= mx + b. m is the slope and b is the y-intercept. The slope is rise/run and the y-intercept is where the line crosses the y-axis.

In the first equation, the slope is -1 and the y-intercept is -8. So, to graph you would start at (0, 8) and move up one unit and then left one unit to get the next point.

For the second equation, the slope is 2/5 and the y-intercept is -1. So, to graph you would do the same thing. Start at (0, -1) and then go up 2 units and right 5 units to get the next point.

I've attached a graph below if you need it.

Apply the distributive property to create an equivalent expression 1/3(3j+6) what the answer
Anna71 [15]

Answer:

\large\boxed{\dfrac{1}{3}(3j+6)=j+2}

Step-by-step explanation:

The distributive property: <em>a(b + c) = ab + ac</em>.

\dfrac{1}{3}(3j+6)=\left(\dfrac{1}{3\!\!\!\!\diagup_1}\right)(3\!\!\!\!\diagup^1j)+\left(\dfrac{1}{3\!\!\!\!\diagup_1}\right)(6\!\!\!\!\diagup^2)=1j+(1)(2)=j+2
