If you would like to solve the equation 3 * (3 * x - 1) + 2 * (3 - x) = 0, you can calculate this using the following steps:

3 * (3 * x - 1) + 2 * (3 - x) = 0
3 * 3 * x - 3 * 1 + 2 * 3 - 2 * x = 0
9 * x - 3 + 6 - 2 * x = 0
7 * x + 3 = 0
7 * x = - 3    /7
x = - 3/7

The correct result would be - 3/7.

Write the standard form equation of the line through the given points. through (0.-4) and (-3,-2)
Alexxx [7]

Answer:

The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is \frac{2}{3}x+y=-4

Step-by-step explanation:

The standard form of equation is Ax+By=C

Finding slope

Using the given points (0,-4) and (-3,-2) we can find slope using formula:Slope=\frac{y_2-y_1}{x_2-x_1}

Slope=\frac{-2-(-4)}{-3-(0)}\\Slope=\frac{-2+4}{-3}  \\Slope=-\frac{2}{3}

Finding y-intercept

Using point (0,4) and Slope=-2/3 we can find y-intercept

y=mx+b\\-4=-\frac{2}{3}(0)+b\\-4=0+b\\b=-4

The slope intercept form of the line through the given points. through (0.-4) and (-3,-2) having slope =-2/3 and b=-4 will be:

y=mx+b\\y=-\frac{2}{3}x-4

Now, standard form of equation will be: \frac{2}{3}x+y=-4

So, The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is \frac{2}{3}x+y=-4

What is the midpoint of a segment in the complex plane with endpoints at 6 -2i and -4 + 6i
alexdok [17]

Answer:

Midpoint of a segment in the complex plane with endpoints at 6 -2i and -4 + 6i is:

1+2i

Step-by-step explanation:

The midpoint of a segment in the complex plane with endpoints at 6 -2i and -4 + 6i is:

\dfrac{6-2i-4+6i}{2} \\\\=\dfrac{2+4i}{2}\\ \\=1+2i

Hence, midpoint of a segment in the complex plane with endpoints at 6 -2i and -4 + 6i is:

1+2i

0 A public beach in Arkansas charges non- residents $12 per day for a fishing license and $3.50 per day for live bait. Arkansas
vfiekz [6]
Non Residents:
f(x)= money in $ paid.
x=number of days.

f(x)=x(12+3.5)=15.5 x

f(x)=15.5x

Arkansas residents
f(x)=money in $ paid.
x=number of days.

f(X)=x+174

Now, we equate functions:

15.5x=x+174    (this is the equation)
15.5x-x=174
14.5x=174
x=174 / 14.5=12

Answer: the number of days is 12 days. The ecuation has one solution, because when I has solved it, I have had one solution.

7(x+4)+1x-9*2= -8x+-10<br> Please show steps
MakcuM [25]

Answer:

<em>-5/4</em>

Step-by-step explanation:

7(x + 4) + 1x - 9 * 2 = -8x + -10

Distribute 7 on left side. Multiply 9 * 2 on left side.

7x + 28 + 1x - 18 = -8x + -10

Combine like terms on left side.

8x + 10 = -8x + -10

Add 8x to both sides. Subtract 10 from both sides.

16x = -20

Divide both sides by 16.

x = -20/16

Reduce the fraction.

x = -5/4
