Answer:

Part 41) The solutions are 3 and 1

Part 42) The solution is 2 only

Step-by-step explanation:

Part 41) we have

$\left|5x-9\right|=x+3$

step 1

Find the first solution (case positive)

$+(5x-9)=x+3$

$5x-x=3+9$

$4x=12$

$x=3$

step 2

Find the second solution (case negative)

$-(5x-9)=x+3$

$-5x+9=x+3$

$5x+x=9-3$

$6x=6$

$x=1$

therefore

The negative case was resolved incorrectly

The solutions are 3 and 1

Part 42) we have

$\left|n-7\right|=3n-1$

step 1

Find the first solution (case positive)

$+(n-7)=3n-1$

$3n-n=-7+1$

$2n=-6$

$n=-3$

<em>Verify</em>

For n=-3

substitute

$\left|-3-7\right|=3(-3)-1$

$\left|-10\right|=-9-1$

$10=-10$ ------> is not true

therefore

$n=-3$ -------> is not a solution

step 2

Find the second solution (case negative)

$-(n-7)=3n-1$

$-n+7=3n-1$

$3n+n=7+1$

$4n=8$

$n=2$

therefore

The solution is 2

Nick has $7.00. Bagels cost $0.75 each, and a small container of cream cheese cost $1.29. Write an inequality to find the number

mestny [16]

If you buy 1 container of cream and an unknown number of bagels, x will represent the number of bagels you buy.
1.29+0.75x<=7.00

I say less than or equal to because you cannot buy more than 7 dollars worth of things.

The table shows the price of some laptop computers.Rebecca wants to spend no more than $450 for a new computer.

hichkok12 [17]

Answer:

Part A) The inequality that represent this situation is equal to

$p\leq \$450$

Part B) Computer A, Computer B,

Step-by-step explanation:

Part A)

Let

p------> the price of a new laptop computer

we know that

The inequality that represent this situation is equal to

$p\leq \$450$

Part B)

we know that

If a price is a solution of the inequality, then the price must satisfy the inequality

<u>Verify each case</u>

case A) For $p=\$419$

Substitute the value of p in the inequality and then compare

$\$419\leq \$450$ ------> is true

therefore

Rebecca can buy computer A

case B) For $p=\$450$

Substitute the value of p in the inequality and then compare

$\$450\leq \$450$ ------> is true

therefore

Rebecca can buy computer B

case C) For $p=\$468$

Substitute the value of p in the inequality and then compare

$\$468\leq \$450$ ------> is not true

therefore

Rebecca cannot buy computer C

case D) For $p=\$451$

Substitute the value of p in the inequality and then compare

$\$451\leq \$450$ ------> is not true

therefore

Rebecca cannot buy computer D
