Using the process of elimination, we will be able to determine the answer. So, 5x+3y=-10 multiply it by *3 to change the equation into 15x+9y=-30. Then to change 3x+5y=-6 multiply it by *5, to change it into 15x+25y=-30. So now with these two equations 15x+9y=-30 and 15x+25y=-30, use subtraction to get rid of the variable x.
Thus,
15x+9y=-30
-
15x+25y=-30
which will leave you with
-16y=0
thus, y=0
Then, plug y back into the original equation to find x
5x+3(0)=-10
5x=-10
x=-2
Thus the point of intersection is (-2,0)
-2 being the x, and y being 0.
Answer:
d. both
Step-by-step explanation:
rectangle have 2 lines of symmetry
Part A: $2.50 * 5 pads = $12.50
$5.75 * 6 pkg markers = $34.50
$12.50 + $34.50 = $47.00 spent on pads and markers
Total spent $65.00 - $47.00 spent on pads and markers = $18.00 left for jars of paint
$18.00 divided by $4.50 = 4 jars of paint that he bought
PART B. The answer is 12 colored pencils.
$18 total spent 3 paint brushes = $9.00
$18 - $9= $9.00 left for color pencils
$9.00 divided by $0.75= 12 colored pencils
the answer is 12 colored pencils
