Answer: 14.2 - 5a

Work: I just did "CLT" of "Combine Like Terms". I did 8 + 6.2 First because 8 is first, then I did 4a - 9a which is -5a, and I combined them, and got the answer. I hope this helps, and stay safe! :)

write an equation in slope intercept form for the line that passes through (4, -4) and is parallel to 3x+4x=2y-9
photoshop1234 [79]

Answer:

\large\boxed{y=\dfrac{7}{2}x-18}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

Convert the equation of a line 3x + 4x = 2y - 9 to the slope-intercept form:

3x+4x=2y-9

7x=2y-9             <em>add 9 to both sides</em>

7x+9=2y       <em>divide both sides by 2</em>

\dfrac{7}{2}x+\dfrac{9}{2}=y\to y=\dfrac{7}{2}x+\dfrac{9}{2}

Parallel lines have the same slope. Therefore we have the equation:

y=\dfrac{7}{2}x+b

Put the coordinates of the point (4, -4) to the equation:

-4=\dfrac{7}{2}(4)+b

-4=7(2)+b

-4=14+b       <em>subtract 14 from both sides</em>

-18=b\to b=-18

Finally we have the equation:

y=\dfrac{7}{2}x-18

What is the solution to this equation 6(x-4)+7=-5
sweet [91]

Answer:

X= 2

Step-by-step explanation:

6(x-4) + 7 = -5  First you distribute the 6

6x - 24 + 7 = -5 Then add like terms

6x -17 = -5 then add 17 to both sides

6x = 12 then divide 12 by 6

x = 2
