|4x + 1| ≤ 5

⇒ - 5 ≤ 4x + 1 ≤ 5

⇔ -6 ≤ 4x ≤ 4

⇔ -1.5 ≤ x ≤ 1

⇒ x ∈ [-1.5; 1]

Using the quadratic formula to solve 11x^2-4x=1, what are the values of X?

Rashid [163]

The correct answers for x would be $\frac{2 +/- \sqrt{15} }{11}$ .

In order to find this, we must first get the equation to equal 0. In order to do that, subtract 1 from each side to get the following.

11 $x^{2}$ - 4x - 1 = 0

Knowing this we can now use the quadratic equation using a = 11, b = -4 and c = -1. The quadratic equation is below.

$\frac{-b +/- \sqrt{ b^{2} - 4ac} }{2a}$

Now we can plug the values into the equation to solve.

$\frac{4 +/- \sqrt{ -4^{2} - 4(11)(-1)} }{2(11)}$

Then simplify using the order of operations.

$\frac{2 +/- \sqrt{15} }{11}$ .

The master family financed a computer that cost $1200. If the interest rate is 19%.how much will the family owe for the computer

Fantom [35]

The answer is $1219

Interest = Total amount * interest rate * time ( I=prt is the formula for calculating interest)

In this case,

Total amount = $1200

Interest rate= $ 0.19

Time span for which interest rate is being calculated= 1/12 (since the rate is yearly and we are calculating interest for a month)

Interest = 1200*0.19*1/12 = 19

So the total amount owned by family at the end of one month = original amount + interest = $1200 + $19 = $1219
