Joaquin has $1,300 in the bank and has investments worth $4,000. He also has $7,000 worth of credit card debt. What is Joaquin's
svetlana [45]
The answer to this question would be: <span>-$1,700

In this question, we can separate the account into positive/debit and negative/credit value. The positive/debit value should be:

Joaquin has $1,300 in the bank
He has $4,000 worth of investment
Total positive value = $1300 + $4000= $5300

The negative value should be 
</span><span>$7,000 worth of credit card debt
</span>Total positive value =$7000
<span>
Then the net worth should be: $5300 - $7000= -$1700</span>

PLEASE HELP Complete the table below to find solutions to the linear equation y=5x+35.
Eddi Din [679]

Answer:

x | y | (x,y)

0 | 35 | (0,35)

3 | 50 | (3,50)

-7 | 0 | (-7,0)

Step-by-step explanation:

Given the equation: y = 5x + 35, to complete the table, plug in the value of x given in the table in each row, to find y.

When x = 0,

y = 5(0) + 35

y = 0 + 35

y = 35

(0,35)

When x = 3,

y = 5(3) + 35

y = 15 + 35

y = 50

(3,50)

When x = -7,

y = 5(-7) + 35

y = -35 + 35

y = 0

(-7,0)

Sqrt(2x-6)=3-x<br> Solve for x
soldi70 [24.7K]

Answer:

x = 3

Step-by-step explanation:

\sqrt{2x - 6}  = 3 - x

Square both sides of the equation

2x - 6 = (3 - x)^{2} = 9 - 6x + x^{2} \\

x^{2}  - 8x + 15 = 0\\

(x - 3)(x - 5) = 0

x = 3 or 5

Now, you must always check your results because a result may not satisfy the original equation.

If x = 3, then \sqrt{2x - 6} = \sqrt{2(3) - 6} = \sqrt{6 - 6}  = \sqrt{0} = 0  and 3 - x = 3 - 3 = 0

So 3 satisfies the original.

If x = 5, then \sqrt{2(5) - 6}  = \sqrt{10 - 6} = \sqrt{4} = 2,  but 3 - x = 3 - 5 = -2.  Therefore, 5 does NOT satisfy the original equation.

That means that x = 3 is the solution to the equation.
