What is the equation of the line that passes through the point (−8,7) and has a slope of 0?

Mathematics

Tresset [83]2 years ago

Answer:

Answer: y=7x+22

Step-by-step explanation:

The point-slope formula states: (y−y1)=m(X−X1)

Where m is the slope and (X1,y1) is a point the line passes through.

Substituting the values from the point and the slope given in the problem allows us to write an equation for this line as: (y−8)=7(X−−2) which then simplifies to (y−8)=7(X+2)

We can also solve for y to put this equation into slope-intercept form.

The slope-intercept form of a linear equation is: y=mx+b

Where m is the slope and b is the y-intercept value.

y−8=(7×X)+(7×2) -which then simplifies to-: y−8=7x+14

y−8+8=7x+14+8

y−0=7x+22

Answer: y=7x+22

Maria, age 28, wants to pay no more than $300 a year in life insurance. what is the face value of the largest 20-year term polic
shusha [124]

The face value of the largest 20-year term policy which Maria can buy without spending more than $300 annually is $158,000.

<h3>What is face value?</h3>

Face is the term used in finance, is used for the amount which has to be paid to the policyholder at the time of maturity.

Maria, age 28, wants to pay no more than $300 a year in life insurance.

The period for this policy is 20-year term.

Annual life insurance premium (per 1,000 dollars of face value) for age 28.

  • A 10-year term for female is 1.28,
  • A 15 year term for female is 1.54,
  • A 20 year term for female is 1.89,
  • A whole life for female is 9.46.

For the 20 year term for female is 1.89 and annular premium is $300. Thus, the face value is,

\rm Face \; Value=\dfrac{300}{1.89}\times1000\\\rm Face \; Value\approx158000

Thus, the face value of the largest 20-year term policy which Maria can buy without spending more than $300 annually is $158,000.

lora16 [44]
Raw material for 500 units per week = 500 x $10 = $5000

Cost of hiring 20 workers per week = 20 x 40  x 25 = $12000

Rental = $2250

Total = 5000 + 12000 + 2250 = $19 250

What is the withdrawal of $150 at the end of each year for 14 years with an interest rate of 7 percent
Tanzania [10]

Answer:

$10.5

Step-by-step explanation:

Given data

P=$150

T= 1year

R= 7%

The simple interest formula will give the accurate amount at the end of each year

A=P(1+rt)

A=150(1+0.07*1)

A=150*1.07

A=$160.5

The withdrawal = 160.5-150= $10.5

Hence the  withdrawal will be  $10.5
