Mathematics
1 answer:
Neporo4naja [7]3 years ago
7 0

Answer:

x = -3

Step-by-step explanation:

To solve this, you need to isolate the variable x, this means only one side of the equation should have the variable x. To do this, you need to do the opposite operation from what's given (if it's addition, use subraction; if it's multiplication, use division; these work vise versa)

  • Subtract 9 from both sides of the equation. This gives you 10x = 4x - 18.
  • Subtract 4x from both sides of the equation. This gives you 6x = -18.
  • Divide both sides by 6. This gives you x = -3

The final answer is x = -3

Eddie, 37 year old male, bought a $70,000, 20 year life insurance policy through his employer. Eddie is paid biweekly. How much
Tatiana [17]

Answer:

(c) 27.81

Step-by-step explanation:

We have been given a table that represents the amount of annual premium of ABC term life insurance company.

Since Eddie is 37 year old male and he bought a 20 year life insurance life policy, so the annual premium charged per $1000 of coverage will be $10.33.

Let us find the total annual premium by multiplying $10.33 by 70 as he bought a $70,000 policy.

\text{The annual premium paid by Eddie}=\$10.33\times 70

\text{The annual premium paid by Eddie}=\$323.18

Since biweekly means 26 times per year, so we will divide the annual premium by 26 to find the amount deducted from each of his paychecks.

\text{The amount deducted from each of Eddie's paychecks for life insurance}=\frac{\$323.18}{26}

\text{The amount deducted from each of Eddie's paychecks for life insurance}=\$27.81461538\approx \$27.81

Therefore, am amount of $27.81 is deducted from each of his paychecks for life insurance and option c is the correct choice.

The expression f(x) = 12(1.035)* models the monthly growth of membership in the new drama club at a school. According to the fun
olga nikolaevna [1]

Answer:

The monthly growth rate is 3.5%.

Step-by-step explanation:

The exponential growth function is given as follows:

y=a(1+r)^{x}

Here,

<em>y</em> = final value

<em>a</em> = initial value

<em>r</em> = growth rate

<em>x</em> = time taken

The provided expression for the monthly growth of membership in the new drama club at a school is:

f(x) = 12\cdot(1.035)^{x}

Comparing this function with the exponential growth function:

a(1+r)^{x}=12(1.035)^{x}\\\\a(1+r)^{x}=12(1+0.035)^{x}

Then value of <em>r</em> is 0.035 or 3.5%.

Thus, the monthly growth rate is 3.5%.
