Prove whether the quadrilateral is a parallelogram using the Distance & Slope Formulas D(-5, -6), E(5, 2), F(4, -4), G(-6, -
amm1812

Answer:

See the distances bellow

Step-by-step explanation:

Given data

D(-5, -6), E(5, 2)

substitute into the expression for the distance

d= \sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)\\\\d= \sqrt((5+5)^2 + (2+6)^2)\\\\d= \sqrt((10)^2 + (8)^2)\\\\d= \sqrt(100 +64)\\\\d= \sqrt((164)\\\\d= 12.80

E(5, 2), F(4, -4)

d= \sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)\\\\d= \sqrt((4-5)^2 + (-4-2)^2)\\\\d= \sqrt((-1)^2 + (-6)^2)\\\\d= \sqrt(1+36)\\\\d= \sqrt((37)\\\\d= 6.08

F(4, -4), G(-6, -12)

d= \sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)\\\\d= \sqrt((-6-4)^2 + (-12+4)^2)\\\\d= \sqrt((-10)^2 + (-8)^2)\\\\d= \sqrt(100+64)\\\\d= \sqrt((164)\\\\d= 12.80

G(-6, -12),  D(-5, -6)

d= \sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)\\\\d= \sqrt((-6+5)^2 + (-12+6)^2)\\\\d= \sqrt((-1)^2 + (-6)^2)\\\\d= \sqrt(1+36)\\\\d= \sqrt((37)\\\\d= 6.08

Determine the number of solutions you will have for the system 4y + x = 16 and y = 4 – x.
pantera1 [17]

Equaling both equations, it is found that the correct option that states the number of solutions you will have for the system is:

  • D: one solution

The equations are:

4y + x = 16 \rightarrow x = 16 - 4y

y = 4 - x \rightarrow x = 4 - y

Equaling both equations for x, we have that:

16 - 4y = 4 - y

3y = 12

y = \frac{12}{3}

y = 4

x = 4 - y = 4 - y = 0

Hence, the system has one solution, which is (0,4), and option d is correct.
