The equation given in the question is written below
- 3 + x^2 = - 19
x^2 = - 19 + 3
x^2 = - 16
x^2 = - (4)^2
Then
x = - 4
So we can see from the above deduction that x is equal to -4 and not +4. I hope the procedure is clear enough for you to understand. You can always use this method for solving problems of similar kind without requiring any help from outside. Only be careful about the calculation part of the problem given.

7/8 - 1/12 its a math question

kati45 [8]

Answer:

19/24 = 0.791666667

Step-by-step explanation:

7/8 - 1/12

Least common multiple of 8 and 12 is 24. Convert 7/8 and 1/12 to fractions with denominator 24.

21/24 - 2/24

Since 21/24 and 2/24 have the same denominator, subtract them by subtracting their numerators.

21 - 2 / 24

Subtract 2 from 21 to get 19.

19/24

The amount of money, in dollars, in a savings account after x years is given by M(x) = 10,000(1.03)x. What does the value 1.03 r

mr Goodwill [35]

Answer:

Option B) There is a 3 percent increase in the savings account each year.

Step-by-step explanation:

we have

$M(x)=10,000(1.03^x)$

This is a exponential function of the form

$y=a(b^x)$

where

M(x) represent the amount of money in a saving account

x represent the number of years

a is the original deposit (y-intercept)

b is the base

r is the rate or percent increase

$b=(1+r)$

The percent increase per year is the base of the exponential function decreased by 1.

so

$r=b-1$

In this problem we have

$a=\$10,000$ ---> original deposit

$b=1.03\\r=1.03-1=0.03=3\%$

Therefore

The percent increase per year is 3%
