The value x = 3 is a solution to each of the following except which?(1) 4x-1=2x +5
(3) 5x +4<19
(2) 2x-8(4) (x+1)(x-3)=0

Answer:

18.8

Step-by-step explanation:

Remember PEMDAS!

To solve the quadratic equation 4x^2 + 20x = -29 using the quadratic formula, we can first rearrange the equation to bring all terms to one side:

4x^2 + 20x + 29 = 0

Now we can identify the coefficients a = 4, b = 20, and c = 29 in the general quadratic equation ax^2 + bx + c = 0. Applying the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

Substituting the values for a, b, and c into the quadratic formula:

x = (-(20) ± √((20)^2 - 4(4)(29))) / (2(4))

Simplifying further:

x = (-20 ± √(400 - 464)) / 8

x = (-20 ± √(-64)) / 8

x = (-20 ± 8i) / 8

Now, we can simplify the expression:

x = -20/8 ± (8i)/8

x = -5/2 ± i

Therefore, the roots of the given quadratic equation are:

x = -5/2 + i

x = -5/2 - i

Final answer:

There are 10 hundredths in one tenth. This can be understood by considering that a dime, representing one tenth of a dollar, is equivalent to 10 pennies, each penny representing one hundredth of a dollar.

Explanation:

In terms of decimals, one tenth is represented as 0.1 and a hundredth is represented as 0.01. Given this, there are 10 hundredths in one tenth (because 0.1 divided by 0.01 equals 10). To understand this using pennies and dimes, consider one dime (which represents one tenth of a dollar) and a penny (which represents one hundredth of a dollar). As there are 10 pennies in a dime, we can conclude that there are 10 hundredths in one tenth.
