Identify the graphical solution to the inequality
NeTakaya

Answer:

A

Step-by-step explanation:

to solve absolute value inequalities you must solve it for when the absolute value is positive and then when it is negative

example, |4| = 4 and -4

first solution will be when we're solving for the positive value:

+(-4x+7) ≥ 27

-4x + 7 ≥ 27

-4x ≥ 20

x ≤ -5   [reverse the symbol when mult or div by a negative]

-(-4x+7) ≥ 27

4x - 7 ≥ 27

4x ≥ 34

x ≥ 34/4 or x ≥ 8 1/2

solution:  x ≤ -5 or x ≥ 8.5

Seven years ago, Douglas purchased a $204,000 home with a 30-year
Stella [2.4K]

Answer:

The new mortgage repayment is $10,580.69  

Step-by-step explanation:

As at the time Douglas lost his job,he has already made repayments on the mortgage for a period of 7 years,by extending the repayment period by another 7 years,Douglas now have a period of repayment of 30 years now(30-7+7).

The new repayment yearly can be computed using the pmt formula in excel as given below:

=pmt(rate,nper,-pv,fv)

rate is the interest rate on mortgage given as 4.25%

nper is the period of repayment now 30 years

pv is the current of balance of $177,533.62

fv is the total amount repayable on the mortgage and it is not known hence taken as zero

=pmt(4.25%,30,-177533.62,0)=$10,580.69

Hamish and hairy work as plumbers. Harry earns a dollar more than 5/4 The amount Hamish orange per hour. The amount Harry earns
Mnenie [13.5K]

Answer:

Harry earns 26 and Hamish earns 20

Step-by-step explanation:

The computation of the amount earned by each one of them is shown below:

Let us assume the hairy be Y

And, the Hamish be M

It is given that Harry earns a dollar i.e more than 5/4

And, it is $2 less than  7/5

So, the equation would be

y = 1.25m + 1  ...........................(i)

And,

y= 1.4m -2  .............................(ii)

Now equal both the equations

1.25m + 1 = 1.4m - 2

3 = 0.15m

So, m = 20

Now put the values of m in any of the above equation to find out the value of Y

Y = 1.25m + 1

= 1.25 (20) + 1

= 26
