Answer:

-1080.

Step-by-step explanation:

I take it that k = -3, if so:-

x = -3yz

  =  (-3)*18*20

   = -1080.

A line that is perpendicular to a line with slope m has slope -1/m which is the opposite reciprocal of the original slope.

In this case the original line in standard form is

2x-4y=-8

transform this into slop intercept form

-4y=-2x-8

4y=2x+8

y=(1/2)x+2

The slope of this original line is 1/2 therefore the perpendicular line will have slope -2

y'=2x'+b

then substitute in the order pair (x',y')

1=2(-2)+b

b=5

Therefore equation of line is

y=2x+5

The graph is just following this equation!

Answer:

First Equation: One Solution

Second Equation: Infinite Solutions

Third Equation: One Solution

Step-by-step explanation:

Let's solve these equations step by step.

[tex]-2x+3=-3x+2\\[/tex]

Subtract 2 and add 2x

[tex]1=-x\\x=-1[/tex]

The only solution here is -1.

[tex]-2x+3=-2x+3[/tex]

Anytime the equations are the same on both sides, we have infinite solutions.

Add 2x

[tex]3=3[/tex]

Any value of x will satisfy this equation.

[tex]-2x+3=2x+3[/tex]

Add 2x and subtract 3

[tex]4x=0\\x=0[/tex]

The only solution here is 0.

I'm assuming you meant to write 8^(-2) or [tex]8^{-2}[/tex] where the -2 is the exponent over the 8.

If my assumption is correct, then we use the rule [tex]a^{-b} = \frac{1}{a^b}[/tex]

So,

[tex]a^{-b} = \frac{1}{a^b}\\\\8^{-2} = \frac{1}{8^2}\\\\8^{-2} = \frac{1}{64}[/tex]

Using the future value formula, it is found that $546,148,903,191,724.25 will be in Devon's account.

It is given by:

[tex]V(n) = P\left[\frac{(1 + r)^{n-1}}{r}\right][/tex]

In which:

In this problem, the parameters are as follows: P = 587, r = 0.0525, n = 40 x 12 = 480.

Hence:

[tex]V(n) = P\left[\frac{(1 + r)^{n-1}}{r}\right][/tex]

[tex]V(480) = 587\left[\frac{(1 + 0.0525)^{480-1}}{0.0525}\right][/tex]

[tex]V(480) = 546,148,903,191,724.25[/tex]

$546,148,903,191,724.25 will be in Devon's account.

Step-by-step explanation:

Given the following question:

[tex]59+x=24[/tex]

To find the answer we are going to use inverse of operations to isolate the variable, doing this we can then find the value of the variable.

[tex]59+x=24[/tex]
[tex]59-59=0[/tex]
[tex]24-59=-35[/tex]
[tex]x=-35[/tex]

Your answer is "x = -35."
