Answer:

Step-by-step explanation:

Add '-2a' to each side of the equation.

5a + -2a = -6 + 2a + -2a

Combine like terms: 5a + -2a = 3a

3a = -6 + 2a + -2a

Combine like terms: 2a + -2a = 0

3a = -6 + 0

3a = -6

Divide each side by '3'.

a = -2

Simplifying

a = -2

5a -2a -6

3a -6

The graph of the linear equation is plotted and y = ( -1/5 )x + 4

Given data ,

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

On simplifying , we get

y = ( -1/5 )x + 4

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = -1/5

And , the y-intercept of the graph of the line is when x = 0

So , when x = 0

y = ( -1/5 ) ( 0 ) + 4

y = 4

Hence , the equation of line is y = ( -1/5 )x + 4

Answer:

$454220

Step-by-step explanation:

Given: B = P[tex](1 + \frac{r}{n} )^{nt}[/tex]

But, B is the future amount

      P is the present amount = $2350

      r is the rate = 1.1%

     n is the number of compounding per year = 12

     t is the number of years = 5

So that;

B = 2350[tex](1+\frac{1.1}{12}) ^{12*5}[/tex]

  = 2350[tex](1.0917)^{60}[/tex]

B = 2350 x 193.2852

  = 454220.22

B = $454220

Thus, her ending balance after 5 years is $454220.

Radicals can be written as exponential expression as following:

[tex]\sqrt{3} = 3^{\frac{1}{2}}[/tex]

[tex]\sqrt[3]{2} = 2^{\frac{1}{3} }[/tex]

[tex]\sqrt[4]{3} = 3^{\frac{1}{4}}[/tex]

[tex]\sqrt[5]{2} = 2^{\frac{1}{5} }[/tex]

The radical of a number is the same as the root of a number. The root can be a square root, cube root, or in general, nth root.

[tex]\sqrt[n]{x} = x^{\frac{1}{n} }[/tex]

Given radicals,

[tex]\sqrt{3} = 3^{\frac{1}{2}}[/tex]

[tex]\sqrt[3]{2} = 2^{\frac{1}{3} }[/tex]

[tex]\sqrt[4]{3} = 3^{\frac{1}{4}}[/tex]

[tex]\sqrt[5]{2} = 2^{\frac{1}{5} }[/tex]
