Answer:

Step-by-step explanation:

4(5x-2y=9)

-2(3x+4y=-5)

20-20x-8y=36

+6x-6x-8y=10

36-20x=10+6x-6x

36-36-20x-6x=10

-26x=10-36

-26x/-26=-26/-26

Prove that the following four points will form a rectangle when connected in order

Lemur [1.5K]

Answer:

Step-by-step explanation:

If the diagonals of the rectangle are congruent,

AC = BD

By using formula to calculate the distance between two points,

Distance between two points = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Distance between A(0, -3) and C(2, 8),

AC = $\sqrt{(8+3)^2+(2-0)^2}$

= $\sqrt{125}$

= $5\sqrt{5}$

Similarly, distance between two points B(-4, 0) and D(6, 5),

BD = $\sqrt{(5-0)^2+(6+4)^2}$

= $\sqrt{125}$

= $5\sqrt{5}$

Therefore, both the diagonals are congruent.

Hence, given quadrilateral ABCD is a rectangle.

(X-4)+(2x-7) Find the sum

sammy [17]

Answer:

3x - 11

Step-by-step explanation:

(x-4)+(2x-7)

We can remove the parenthesis because we are adding and not multiplying.

x - 4 + 2x - 7 Combine like terms

x + 2x - 4 - 7

3x - 4 + - 7

3x - 11
