Solve the pair of simultaneous equations and leave the answer as a fraction in

Elena-2011 [213]

Answer:

x = 11/3 = 3 2/3

y = 13/3 = 4 1/3

Step-by-step explanation:

Here, we want to solve the system of equations simultaneously

x + y = 8

2x -3 = y

From the second equation, we have an equation for y

we can simply proceed to substitute this into the first equation

x + 2x - 3 = 8

3x - 3 = 8

3x = 8 + 3

3x = 11

x = 11/3

Recall;

y = 2x - 3

y = 2(11/3) - 3

y = 22/3 - 3

y = (22-3(3))/3

y = (22-9)/3 = 13/3

Answer:

$\huge \red { \frac{4 {x}^{6} {z}^{4} }{9{y}^{4} }}$

Step-by-step explanation:

$\huge \frac{16 {x}^{4} {y}^{ - 3} {z}^{4} }{3 6{x}^{ - 2}y {z}^{0} } \\ \\ \huge= \frac{16 {x}^{4} {x}^{ 2} {z}^{4} }{3 6{y}^{3}y \times 1 } \\ \\ \huge = \frac{16 {x}^{4 + 2} {z}^{4} }{3 6{y}^{3 + 1} } \\ \\ \huge \purple {= \frac{4 {x}^{6} {z}^{4} }{9{y}^{4} }} \\$

Y is the midpoint of segment XZ. The coordinates of X are (2, 4) and of Y are (-1, 1). Find the coordinates of Z. ...?

Elenna [48]

Given x(x1,y1)=(2,4)
z(x2,y2)=(x2,y2)
midpoint (x,y)=(-1,1)
2+x2/2=-1;4+y2/2=1
2+x2=-2;4+y2=2
x2=-4;y2=-2
z(x2,y2)=(-4,-2)
