What is an equation of the line that passes through the point (2, -6) and is parallel
fomenos

Answer: y=-6

Step-by-step explanation:

First convert the equation -2y= 8 into y intercept form by divide both sides by -2.

-2y = 8  

y= -4     Now that the line is in y intercept form we can now determine the slope.The slope is 0  so -4 in this case is the y intercept.

Remember lines that a parallel needs to have the same slope but different y-intercepts.

So if the slope of the line y=-4 is 0 then the slope of line that passes through the point (2,-6)  

So using the y intercept form formula which says that y=mx+b where m is the slope and b is the y-intercept, we could plot in the values for y and x and solve for b to write the equation.

y is -6 and x is 2

-6 = 0(2) + b

-6 = 0 + b

b= -6  

In this case the y intercept is -6 so since the slope is zero we will have the equation  y = -6

7/30+9/20 what is the answer pls hurry im so confused
Svetradugi [14.3K]

Here is your answer:

  • \frac{7}{30} + \frac{9}{20}
  • Find common denominator:
  • 30 \times 20 = 60 /20 \times 30 = 60
  • Common denominator is 60:
  • \frac{7}{30} + \frac{9}{20} = \frac{140}{60} + \frac{270}{60}
  • 140 + 270 = 410
  • = \frac{410}{60}
  • \frac{410}{60} \div 2 = \frac{205}{30} \div 5 = \frac{41}{6}
  • = \frac{41}{6} or 6\frac{5}{6}

Hope this helps!

What are the potential solutions to the equation 2ln(x+3)=0
skad [1K]
2\ln(x+3)=0\implies \ln(x+3)^2=0\implies e^{\ln(x+3)^2}=e^0\implies (x+3)^2=1

Expanding the left side gives

x^2+6x+9=1\implies x^2+6x+8=0\implies (x+4)(x+2)=0

which gives two solutions, x=-4 and x=-2. But if x=-4, then \ln(x+3)=\ln(-1), but this number isn't real, so x=-4 is an extraneous solution. Meanwhile if x=-2, you get \ln(-2+3)=\ln1=0, so this solution is correct.

"Potential solutions" might refer to both possibilities, but there is only one actual (real) solution.

Which expression is equivalent to 2(c+7)-18x+4/5
mestny [16]

Answer:

2c - 18x + 74/5

Step-by-step explanation:

<u>Step 1:  Distribute </u>

2(c + 7) - 18x + 4/5

(2 * c) + (2 * 7) - 18x + 4/5

<em>2c + 14 - 18x + 4/5 </em>

<u>Step 2:  Combine like terms </u>

2c + 14 - 18x + 4/5

<em>2c - 18x + 74/5 </em>

Answer:  2c - 18x + 74/5
