3 \dfrac{1}{4} - ( -  \dfrac{1}{2} ) =  3 \dfrac{1}{4} +  \dfrac{1}{2}  =  3 \dfrac{1}{4} +  \dfrac{2}{4}  =   3 \dfrac{3}{4}

9 3 -3/4 -10 1/2 -1.75 least to greatest
Mazyrski [523]

-10, -1.75, -3/4, 1/2, 3, 9

_____________________________

-3/4 converts to -0.75,

and 1/2 converts to 0.5. With -10 being farthest from zero on the number line, it would be the smallest. -1.75 would be the second smallest. Keeping in mind that -3/4 converts to -0.75, it would be the 3rd smallest. 1/2, or 0.5 would be greater, as it is the smallest POSITIVE number. Then you do 3, as it as a whole number, but still not the greatest. 9 would be the greatest.

hope i was helpful;-)

( use elimination) on 3x+5y=12 and x-3y=4
Elena L [17]

Answer:

x=4 y=0

Step-by-step explanation:

3x+5y=12

-(x-3y=4)

3x+5y=12

3(-x+3y=-4)

3x+5y=12

-3x+9y=-12

14y=0

y=0

Then, substitute the y into the equation to find x

x-3(0)=4

x=4

What is the equation of the funcion that is graphed as line b?
dolphi86 [110]

Answer:

The equation for b would be y = 1/2x + 1

Step-by-step explanation:

In order to find this, start by finding two points on the line. We'll use (0,1) and (2, 2). From there we start by finding the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (2 - 1)/(2 - 0)

m = 1/2

Now using that, we can plug it, along with a point into point-slope form to get the answer.

y - y1 = m(x - x1)

y - 1 = 1/2(x - 0)

y - 1 = 1/2x

y = 1/2x + 1
