Answer:

(1,4)

Step-by-step explanation:

The two lines intersect at 1,4 when you graph them

The first equation is already in slope intercept from, so you know the y-int. is 7 and the slope is 3. However, the second equation must be put in slope int. form.

5x+2y=3

move the y to the other side

5x=3-2y

move the 3 to the other side, so the y variable is by itself

5x-3=-2y

divide by -2 to the equation is equal to y

(-5x/2)+(3/2)=y

you now know the y int. of the second equation is 3/2 and the slope is -5/2

know that you know the slop int. formulas for both equations you can graph them

Hello There!

Dividing a fraction is the same thing as multiplying by its reciprocal.

This means that \frac{3}{4} ÷ \frac{5}{12} is the same as multiplying \frac{3}{4} by \frac{12}{5}.

So basically when you divide you leave the first fraction alone but the second fraction in this case, 5/12 you would flip the number on top and the number on bottom to 12/5.

HAVE A GREAT DAY!
