\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{-5})~\hspace{10em} slope = m\implies -1 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-5)=-1(x-3)\implies y+5=-x+3


\bf y=-x\underset{\uparrow }{-2}\leftarrow \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}~\hfill \stackrel{y-intercept}{(0,-2)}

4x - 7 = -3x<br><br> What is the answer?
soldi70 [24.7K]

Answer:

x = 1

Step-by-step explanation:

1. Add 3x to both sides of the problem

  • 4x + 3x - 7 = -3x + 3x
  • -3x + 3x cancels out and leaves us with zero
  • 7x - 7 = 0

2. Add 7 to both sides

  • 7x (- 7 + 7) = 0 + 7
  • -7 + 7 cancels out
  • 7x = 7

3. Divide both sides by 7

  • 7x/7 = 7/7
  • x = 1

To make sure our answer is correct we can plug in 1 to x in the problem

  • 4(1) - 7 = -3(1)
  • 4 - 7 = -3 : True

The ratio of the units digit to the tens digit in a two-digit number is one-half. the tens digit is two more than the units digi
vodomira [7]
Let the first digit of the 2-digit number be x and the second digit be y.
Then the ratio (x/y) equals (1/2).  Write a formula for y in terms of x.

The tens digit is 2 more than the units digit.  Using the letters x and y, write out the proper equation.

Now solve your two equations simultaneously for x and y.

Jade wants to buy a $200,000 term life insurance policy. She is 34 years old. Using the premium table, what is her annual premiu
AnnZ [28]

Premium rates are usually for  premium per fixed face value. Jade's annual premium for a 10 year policy is given by Option b: $1,202

<h3>How to calculate the total annual premium for $x ?</h3>

If its given that the annual premium is $p per $y face value, then we can calculate the annual premium for $1 face value and then use it to calculate annual premium for $x.

Using proportions, we get:

\rm \$y \: face \: value : \$p \: annual \: premiun\\\\\rm \$1 \: face \: value : \$\dfrac{p}{y} \: annual \: premiun\\\\\rm \$x\:face\: value : \$\dfrac{p \times x}{y} \: annual \: premiun\\

For given case, from the tables, we see that for age 34, and 10 year life insurance for female gender , there is annual premium of 6.01 per $1000 face value.
Thus, we have p = 6.01, y = 1000

Since Jade wants to buy Life insurance for $200,000, thus, x = $200,000

Putting it in the above derived formula, we get:

\rm \$x\:face\: value : \$\dfrac{p \times x}{y} \: annual \: premium\\\\\rm \$200000\:face\: value : \$\dfrac{6.01 \times 200000}{1000} \: annual \: premium\\ = \$1202 \: annual \: premiun

Thus, Jade's annual premium for a 10 year policy is given by Option b: $1,202
