What are the two solutions of 2x2 = –x2 – 5x – 1?
Answer:
The answer is
[tex]x = \frac{ - 5 + \sqrt{13} }{6} \: \: \: \: or \: \: \: x = \frac{ - 5 - \sqrt{13} }{6} [/tex]Step-by-step explanation:
2x² = - x² - 5x - 1
Rearrange the terms and simplify
That's
2x² + x² + 5x + 1 = 0
3x² + 5x + 1 = 0
Using the quadratic formula solve the equation
That's
[tex]x = \frac{ - b\pm \sqrt{ {b}^{2} - 4ac} }{2a} [/tex]From the question
a = 3 , b = 5 , c = 1
So we have
[tex]x = \frac{ - 5\pm \sqrt{ {5}^{2} - 4(3)(1) }}{2(3)} \\ = \frac{ - 5\pm \sqrt{25 - 12} }{6} \\ = \frac{ - 5\pm \sqrt{13} }{6} [/tex]We have the final answer as
[tex]x = \frac{ - 5 + \sqrt{13} }{6} \: \: \: \: or \: \: \: x = \frac{ - 5 - \sqrt{13} }{6} [/tex]Hope this helps you
Answer: ITS C!!!!!!!
Step-by-step explanation:
Help asap!!! I really need help on this
Step-by-step explanation:
The function is positive when the graph is over the x-axis, and negative when the graph is under the x-axis.
As we can see from the graph, it has x-intercepts at x = -3 and x = 3.
Since the graph curves upwards, the function is positive in intervals (-∞, -3) U (3, ∞) and negative in the interval (-3, 3).
True or False. The graph below is a function. -10 8 6 4 2 -10 -8 -6 -4 -2 2 4 6 8 10 -2 + -4 -6- -8 -10 True False

What is the conjecture of 1, 8, 27, 64, __, __, __, __, __, what is the pattern?
Answer:
The pattern = 1³, 2³ 3³, 4³, 5³, 6³, 7³, 8³, 9³,
The answer = 1, 8, 27, 64, 125, 216, 343, 512, 729,
Step-by-step explanation:
what is the pattern?
We are given the following sequence:
1, 8, 27, 64, __, __, __, __, __,
Observing the sequence above, for every consecutive natural number
x, x + 1, x + 2, x + 3.......
The above pattern is : the cube of every consecutive natural number. That is: x³, (x + 1)³, (x + 2)³, (x + 3)⁴
1, 8, 27, 64, __, __, __, __, __,
= 1³, 2³ 3³, 4³, 5³, 6³, 7³, 8³, 9³,
Hence, the answer
1, 8, 27, 64, 125, 216, 343, 512, 729,

If f(x)=x+1, find f(x+10).
Answer:
x + 11
Step-by-step explanation:
Substitution!
Since you're trying to find f(x+10), you would replace each x in the equation (in this case only one) with x+10.
So instead of
[tex]x+1[/tex]
it would be
[tex](x+10)+1 = x + 10 + 1 = x + 11[/tex]
Solve for x: 3(x + 1) = −2(x − 1) − 4
Answer:
x=
−3
2
Step-by-step explanation:
Let's solve your equation step-by-step.
3(x+1)=−1(x−1)−4
Step 1: Simplify both sides of the equation.
3(x+1)=−1(x−1)−4
(3)(x)+(3)(1)=(−1)(x)+(−1)(−1)+−4(Distribute)
3x+3=−x+1+−4
3x+3=(−x)+(1+−4)(Combine Like Terms)
3x+3=−x+−3
3x+3=−x−3
Step 2: Add x to both sides.
3x+3+x=−x−3+x
4x+3=−3
Step 3: Subtract 3 from both sides.
4x+3−3=−3−3
4x=−6
Step 4: Divide both sides by 4.
4x

What is multiplication?Multiplication is the process of determining the product of two or more numbers in mathematics. A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
The model has 5 rows and 3 columns shaded. The multiplication equation will be written below,

The super speedway at Daytona International Speedway is 2.5 miles long. The road course there is 1.4 times as long as the super speedway. How long is the road course?
Answer:
3.5 miles
Step-by-step explanation:
From the question, we have the following information:
The super speedway at Daytona International Speedway is = 2.5 miles
long
The road course there is = 1.4 times as long as the super speedway.
How long is the road course?
The length of the road course is calculated as:
1.4 × length of the super speedway
1.4 × 2.5 miles
=>3.5 miles
Therefore, length of the road course I s 3.5 miles.
if 3x+k 2x+9 x+13 are three consecutive terms of an ap fine k
Step-by-step explanation:
Since there are in arithmetic progression, 2(2x + 9) = (3x + k) + (x + 13).
=> 4x + 18 = 4x + 13 + k
Hence k = 5.

The total length of a vehicle is 205.83 inches. What is the length of the vehicle rounded to the nearest whole number?
A. 200 in B. 205 in C. 206 in D. 210 in
Answer:
If rounded up by the nearest whole number, it'd be 210, because it isn't using the decimal numbers, and the whole number would get the boot, meaning only 200 and 10 would remain. Please let me know if this helped.
Reduce the most possible thx <3
Answer:
1/2
Step-by-step explanation:
To make this a equal fraction we have to make the denominator(the bottom) the same
So the fraction would be multiplied by 2 = 10/6
Now we add 10/6 by -7/6
This is the same thing as 10/6 - 7/6 which is 3/6
Now we simplify 3/6. 1/2

Solve the inequality 6x – 8 > 4x + 26.
Ox<9
Ox< 17
Ox>9
Ox> 17
Answer:
The answer is x>17
Step-by-step explanation:
First subtract 4x from both sides
6x - 8 > 4x + 26
-4x. -4x
2x - 8 > 26
8 is negative so to get rid of it add 8 to -8 and 26
2x - 8 > 26
+8. +8
2x > 34
x needs to be by itself so divide both sides by 2
2x > 34
2. 2
x > 17
