66 = (2x - 1) \times (x - 1) \\ 66 = 2 {x}^{2}  - 3 + 1 \\ 65 - 2 {x}^{2}  + 3x = 0 \\  - 65 + 2 {x}^{2}  - 3x = 0 \\ 2 {x}^{2}  + 10x - 13x - 65 = 0 \\ 2x \times (x + 5) - 13 \times (x + 5) = 0 \\ (x + 5) \times (2x - 13) = 0 \\  \\ x + 5 = 0 \\ 2x - 13 = 0 \\  \\ x =  - 5 \\ x =  \frac{13}{2}  \\  \\

Line h contains the points (3,0) and (0,4). which point lies on a line that is perpendicular to line h and passes through point
Iteru [2.4K]
(3,0)(0,4)
slope = (4 - 0) / (0 - 3) = -4/3
A perpendicular line will have a negative reciprocal slope. So our perpendicular line has a slope of 3/4

y = mx + b
slope(m) = 3/4
(-6,-5)....x = -6 and y = -5
now sub into the formula and find b, the y int
-5 = 3/4(-6) + b
-5 = -18/4 + b
-5 + 18/4 = b
-20/4 + 18/4 = b
-2/4 = b
so ur perpendicular line is : y = 3/4x - 2/4....or 3x - 4y = 2

and ur point (6,4) lies on the perpendicular line <===

Consider the following rational numbers -5.1 -5 1/3 -5 -5 3/5 list them in order from least to greatest
jok3333 [9.3K]

Answer:

-5.6, -5.3, -5.1, -5.

Step-by-step explanation:

Convert the first fraction to a decimal.

-5 1/3 is equal to -5.3333333333

Round to the nearest tenth.

-5.3333333333 rounded to the nearest tenth is -5.3.

<em>-5 1/3 = -5.3.</em>

<em />

Convert the second fraction to a decimal.

-5 3/5 is equal to -5.6.

The fraction is already rounded, so that's all for the second one.

<em>-5 3/5 = -5.6.</em>

<em />

The new set of numbers we have include -5.1, -5.3, -5, and -5.6.

We can now sort from least to greatest.

The first number is -5.6.

The second number is -5.3.

The third number is -5.1.

The fourth number is -5.

Listing the numbers -5.1, -5.3, -5, and -5.6 from least to greatest would result in -5.6, -5.3, -5.1, and finally -5.
