I need to solve and find x. 4x+15<40

antiseptic1488 [7]

Answer:

$x$ or $x< 6 \frac{1}{4}$

Step-by-step explanation:

4x + 15 < 40

Subtract 15 from both sides

4x + 15 - 15 < 40 - 15

4x < 25

Divide both sides by 4

4x/4 < 25/4

x < 6.25

x < 6 1/4

Luna invested $8000 for 36 months at an interest rate of 4.8% per month. How much money will Luna have at the end of her investm

Degger [83]

Answer : $ 9, 152

Luna invested $8000 for 36 months at an interest rate of 4.8%

Let P = principal

T = time

r = rate

Using the simple interest,

$\begin{gathered} I\text{ =}\frac{P\text{ x R x T}}{100} \\ P\text{ = \$8000} \\ r\text{ = 4.8\%} \\ t\text{ = 36 months} \\ 12\text{ months = 1 year} \\ 36\text{ months = x year} \\ \text{Cross multiply} \\ 12\cdot\text{ x = 1 x 36} \\ 12x\text{ = 36} \\ \text{Divide both sides by 12} \\ x\text{ = 36/12} \\ x\text{ = 3 years} \\ \text{Hence, t = 36 months = 3 years} \\ I\text{ = }\frac{8000\text{ x 3 x 4.8}}{100} \\ I\text{ = }\frac{115,\text{ 200}}{100} \\ I\text{ = \$1, 152} \end{gathered}$

The total balance = Interest + principal

Balance = 1, 152 + 8000

Balance =$9, 152

The total money she will have at the end of the investment is $9, 152

What is the center of the circle with the equation: X2 + y2 +18x + 14y + 105 = 0

professor190 [17]

Answer:

(9, -7)

Step-by-step explanation:

$x^2+y^2+18x+14y+105=0\\$

Rearrange like x and y terms next to each other, then complete the square on both.

$(x-9)^2-361 + (y+7)^2 - 49 + 105 = 0$

The negative of the # numbers instead the brackets give you the centre of the circle.
