What is the equation of the line that is parallel to the given
Mrac [35]

Answer:

Step-by-step explanation:

is the given line  3x - 4y = -17?

then,

- 4y = -3x -17

y=(3/4)x+17/4

it is parallel, so slope of our line is 3/4 or 0.75

y=0.75x+b

next, lets plug in the given point to get the y-int

2=0.75*(-3)+b

2=-2.25+b

b-2.25=2

b=4.25

the equation is y=0.75x+4.25

does this clear anything, or am I off topic? please tell me I will help you

What number should be added to both sides of the equation to complete the square? x2 – 6x = 5
choli [55]

Answer: Add 9 to both sides to complete the square

Step-by-step explanation:

The formula for the number you need to add to complete the square is (b/2)^2. In this case, b = -6, so:

(b/2)^2 = (-6/2)^2 = (-3)^2 = 9.

(After adding 9 to both sides, you will get x^2 - 6x + 9 = 14 which can be factored to (x - 3)^2 = 14)

What is the length of side TS?
balandron [24]

Step-by-step explanation:

In order to find the length of side TS, first we need to find the length of side TR which is perpendicular to side QS.

By Geometric mean property:

{TR}  =  \sqrt{6 \times 12}  \\  \therefore \:  {TR}  =  \sqrt{6 \times 6 \times 2}   \\ \therefore \:  {TR}  =  6\sqrt{2}   \\  \\ In \:  right \:  \triangle  \: TRS:  \\ TS^2 = TR^2 + RS^2  \\ \therefore \:  (3x)^{2}  =  {(6 \sqrt{2}) }^{2}  +  {(12)}^{2}  \\  \therefore \:  9x^{2}  =  72 +  144 \\  \therefore \:  9x^{2}  =2 1 6 \\ \therefore \:  x^{2}  = \frac{2 1 6}{9}  \\ \therefore \:  x^{2}  =24 \\ \therefore \: x =  \sqrt{24}  \\  \therefore \: x = 4.89897949 \\ \therefore \: x  \approx \: 4.9 \\ \therefore \: 3x  = 3 \times 4.9 \\ \therefore \: 3x  =14.7 \\    \huge \red{ \boxed{\therefore  \: TS = 14.7 \: units}}
