Step-by-step explanation:
The average is -22.2 (mean)
-46,-39,-28,-28,-25,-17,-11.-6 You cross out the lowest and highest until you reach the middle, which is -26.5(median)
The mode is -28 as it is the most repeated number
The range is 40 as when you subtract a negative it turns into the absolute value.
Solve for x in the equation x squared 14 x 17 = negative 96.
The value of x in the given quadratic equation is determined as -7 ± 8i.
Solution of the quadratic equationThe solutiion to the linear equation is determined as follows;
x² + 14x + 17 = -96
x² + 14x + 17 + 96 = 0
x² + 14x + 113 = 0
solve the equation using formula method;
a = 1, b = 14, c = 113
[tex]x = \frac{-b \ \ \pm\sqrt{b^2 - 4ac} }{2a} \\\\x = \frac{- 14\ \ \pm\sqrt{(14)^2 - 4(1\times 113)} }{2(1)} \\\\x = \frac{- 14\ \ \pm\sqrt{-256} }{2}\\\\x = \frac{- 14\ \ \pm\sqrt{256} \times \sqrt{-1} }{2}\\\\x = \frac{-14 \ \ \pm 16 \times i}{2} \\\\x = -7 \pm 8i[/tex]
Thus, the value of x in the given quadratic equation is determined as -7 ± 8i.

Answer:
[tex]\frac{1}{2}[/tex]
Find the least common factors of both numbers.
[tex]1/3~has~4\\2/12~has~1[/tex]
Multiply the numerator and denominator.
[tex]\frac{1 * 4}{3 * 4} = \frac{4}{12} \\\\\frac{2 * 1}{12 * 1} = \frac{2}{12}[/tex]
Add both numbers together. That does not mean you have to add the denominators. When the denominators are the same, keep them the same.
[tex]\frac{4}{12} +\frac{2}{12} = \frac{6}{12}[/tex]
Simplify.
[tex]\frac{6}{12} -- > \frac{1}{2}[/tex] because they are both halves.
Part I: Determining the common denominator of the terms
Given expression:
[tex]\dfrac{1}{3} + \dfrac{2}{12}[/tex]
To simplify the expression, we need to determine the common denominator of both fractions (1/3 and 2/12). To determine the common denominator of both fractions, we need to determine the LCM of the denominators (12 and 3). Simply write the multiples of (12 and 3) and determine the least common multiple (LCM).
⇒ Multiples of three: 3, 6, 9, 12, 15, 18...⇒ Multiples of twelve: 12, 24, 36, 48, 60...Since the LCM is 12, our common denominator is 12.
Part II: Multiplying both denominators by a number which is equivalent to 12
Now, multiply both denominators by a number such that the denominators are equivalent to 12. Keep in mind that the number you multiply the denominator should also be multiplied to the numerator.
[tex]\implies \dfrac{x}{3x} + \dfrac{2y}{12y} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \huge\text{[}3x = 12; 12y = 12\huge\text{]}[/tex]
[tex]\implies \dfrac{4}{3(4)} + \dfrac{2(1)}{12(1)} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \huge\text{[}x = \dfrac{12}{3} = 4; y = \dfrac{12}{12} = 1 \huge\text{]}[/tex]
[tex]\implies \dfrac{4}{12} + \dfrac{2}{12}[/tex]
Part III: Adding the fractions
Since the denominators are the same, we can now add the fractions;
[tex]\implies \dfrac{6}{12}[/tex]
Part IV: Simplifying the fraction obtained from the above
Since 6 is divisible by 12, we can further simplify the fraction.
[tex]\implies \dfrac{6 \times 1}{6 \times 2}[/tex]
[tex]\implies \boxed{\dfrac{1}{2}}[/tex]

One morning, Justin drove 2 hours before stopping to eat lunch. After lunch, he increased his speed by 10 mph. If he completed a 220-mile trip in 6 hours of driving time, how fast (in miles per hour) did he drive in the morning
Answer:
30
Step-by-step explanation:
Let x be his speed at the morning, in miles per hour.
Then his speed after lunch was (x+10) mph.
2x + 3(x+10) = 220.
2x + 3x + 50 = 220

4ln(7x+3)+12=40
Answer:
[tex]x=\frac{e^7-3}{7}[/tex]
Step-by-step explanation:
4* ln(7x+3) + 12 = 40
4* ln(7x+3) + 12 - 12 = 40 - 12
4* ln(7x+3) = 28
ln(7x+3) = 28/4
ln(7x+3) = 7
e^7 = (7x + 3)
