What is the equation of a line with a slope of -1/2 and passes through the point (6,-6)
Studentka2010 [4]
Y = mx + b
slope(m) = -1/2
(6,-6)....x = 6 and y = -6
now we sub into the formula and find b, the y int
-6 = -1/2(6) + b
-6 = - 3 + b
-6 + 3 = b
-3 = b

so ur equation is : y = -1/2x - 3 <==

Please help!!!!!!!!!!!!!!
GREYUIT [131]
Pay attention here because I'm adding an extra letter to our circle to help keep track of the values in our formula.  OUTSIDE of the intercepted arc I'm adding the point E.  So the major arc is arc BEG and the minor arc is arc BG.  The formula then for us is ∠BFG= \frac{1}{2}(arcBEG-arcBG).  We just don't have values for the arcs yet.  If the measure of the central angle is 4x+238, then the measure of arcBG is also 4x+238.  Around the outside of the circle is 360°.  So we will use it in an expression.  ArcBEG=360-(4x+238).  Fitting that into our formula we have 2x+146= \frac{1}{2}[(360-4x-238)-(4x+238)].  Doing all the simplifying inside there we have 2x+146= \frac{1}{2}(122-4x-4x-238) and 2x+146= \frac{1}{2}(-8x-116).  Multiply both sides by 2 to get rid of the fraction: 4x+292=-8x-116.  Combine like terms to get 12x = -408 and divide to solve for x.  x = -34.  Fourth choice down from the top.

Can anyone help me asap plzz.
alexandr1967 [171]

the answer is c.

you have to multiply by -3 on both sides to get c on its own.

therefore, c is greater than or equal to -9.

in a, c is less than or equal to 9 so thats not the answer.

In b, c is greater than or equal to 9 but it has to be -9.

in d, c is less than or equal to -9.

the answer is c

podryga [215]

Answer:

The length of the patio is 32 ft and the width is 13 ft

Step-by-step explanation:

see the attached figure to better understand the problem

Let

L ----> the length of his patio

W ---> the width of his patio

we know that

L+2W=58 ----> equation A

L=2W+6 ----> equation B

substitute equation B in equation A and solve for W

2W+6+2W=58

4W+6=58

4W=58-6

4W=52

W=13\ ft

Find the value of L

L=2W+6  ----> L=2(13)+6=32\ ft

therefore

The length of the patio is 32 ft and the width is 13 ft
