Gabriella and Stephanie each improved their yards by planting grass sod and ornamental grass. They bought their supplies from th

e same store. Gabriella spent $172 on 14 ft2 of grass sod and 2 bunches of ornamental grass. Stephanie spent $158 on 7 ft2 of grass sod and 9 bunches of ornamental grass. Find the cost of one ft2 of grass sod and the cost of one bunch of ornamental grass.

14x + 2y = $172
7x + 9y = $158 (x= grass sod y= ornamental grass)

14x + 2y= 172
14x + 18y= 316 (Multiply Equation 2 by 2 to eliminate x)
when you subtract both equations you get -16y= -144 therefore y=9
Final step: Plug in 14x + 2(9) = 172       14x=154      x=11
1 sq ft of grass sod costs $11 and one bunch of ornamental grass costs $9

Help I don’t understand the first part but understand the second
Lunna [17]

Answer:

Step-by-step explanation:

Complete the square

x^{2} + 2x - 13 = 0

x^{2} + 2x        = 13

x^{2} + 2x + 1^{2} = 13 +1 (take 1/2 of the b term , the 2 )

x^{2} + 2x + 1 = 14

(x +1)^2 = 14

On the X-axis y=0

So

x2y−x2+4y=0

becomes

x2(0)−x2+4(0)=0

→−x2=0

→x=0

On the Y-axis x=0

and the original equation

x2y−x2+4y=0

becomes

(0)2y−(0)2+4y=0

→y=0

The only intercept for the given equation occurs at (0,0)

Which graph shows a system of equations with no solutions?
podryga [215]

Graph of Parallel lines shows a system of equations with no solutions

Step-by-step explanation:

Consider a set of equations

7x - 2y = 16\\21x + 6y =24

If we solve this both equations using any one of the solving method, (Substitution method) then we will get

7x-2y=16\\7x=16+2y\\x=\frac{16+2y}{7}

substituting the following x in 2nd equation (21x + 6y = 24) We get

21(\frac{16+2y}{7} )+6y=24\\3(16+2y)+6y=24\\48+6y+6y=24\\12y=24-48\\y=-\frac{24}{12} \\y=-2

Put y= -2 in x equation

x=\frac{16+2(-2)}{7}\\ x=\frac{16-4}{7}\\\x=\frac{12}{7} \\x=1.71

Comparing these (x,y) values we can understand that they never meet at a point
