two negative integers are 8 units apart on the number line and have a product of 308. which equation could be used to determine x, the smaller negative integer? x2 8x – 308
The equation that could be used to determine x is ([tex]x^{2}[/tex] + 8x - 308).
As per the question, the small integer is x. So, the large integer will be (x + 8).
Also, the question mentions that their product is 308. Representing the given information in mathematical equation form -
x (x + 8) = 308
Performing multiplication on Left Hand Side of the equation
x² + 8x = 308
Shifting 308 from Right Hand Side to the Left Hand Side of the equation. the equation that will form is -
x² + 8x – 308 = 0
On solving this quadratic equation, we will get the negative numbers, which will validate our formed equation.
x² + 8x – 308 = 0
x² + 22x - 14x – 308 = 0
x (x + 22) - 14 (x + 22) = 0
(x + 22) (x - 14) = 0
x = -22 and 14
Since the numbers are negative, hence, value of small number is -22.
Large number = -22 + 8
Large number = -14
Thus, the small and large number is -22 and -14.
Therefore, the correct equation is x² + 8x – 308 = 0.

James and Willis are both painting a room. James could complete it in 6 hours by himself. Together they can complete the room in 2 hours. How long would it take Willis to paint the room by himself?
Answer: Willis will take 3 hours to paint the room by himself.
Step-by-step explanation:
Given: Time taken by James to complete job by himself = 6 hours
Let Time taken by Willis to complete job by himself = t hours
Together they take 2 hours.
[tex]\dfrac{1}{6}+\dfrac{1}{t}=\dfrac{1}{2}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{2}-\dfrac{1}{6}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{3-1}{6}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{2}{6}\\\\\Rightarrow\ t=\dfrac{6}{2}\\\\\Rightarrow\ t=3[/tex]
So, Willis will take 3 hours to paint the room by himself.

The magnitude of the complex number is expressed as;
|z| = √x²+y²
Given the complex number z = 4i+3j, x = 4 and y = 3
Substitute
|z| = √x²+y²
|z| = √3²+4²
|z| = √9+16
|z| = √25
|z| =5

2. (2, 48)
3. (-2, 2)
4. (-2, -20)
Answer:
1
Step-by-step explanation:
A system of equation is a set of a number of equation used for finding their solution. The solution of the given system of equations is (2,-22). The correct answer is option 1.
What is a system of equations?A system of linear equation can be defined as a number of equations needed to find the solution. On the basis of the number of solutions a set of equations can be called either consistent or inconsistent.
The given equations are
y = -6x -10 and y = -1/2x -21
They can be rewritten as,
y + 6x = -10 ------------------- (1)
2y + x = -42 ------------------- (2)
To get the value of x ,
(2y + x) - 2(y + 6x) = -42 - 2×(-10)
=> -11x = -22
=> x = 2
Substitute x = 8 in equation (1) to get y,
y = -10 - 12
y = -22
Hence, the solution for the given system of equation is (2,-22).

5x - 4y = 19
x + 2y = 8
Answer:
not sure what your question is but if youre trying to solve for the system of equations your awnser is (5,3/2)
Answer:
x= 5, y= 3/2
Step-by-step explanation:
5x -4y =19 (Equation 1)
x+ 2y=18 (Equation 2)
Using substitution method,
From equation(2),make x the subject of formula
x= 8-2y (Equation 3)
Substitute equation 3 into equation 1
5x -4y= 19
5(8-2y) -4y = 19
40 -10y -4y = 19
40-14y=19
Collect like terms
40-19=14y
21=14y
y= 21/14 = 3/2
Substitute for y in equation 3
x= 8 -2y

Solve the equation 2 (x - 1/2)=3(5 - 2x) Show the steps in your solution.
Answer:
x = 2
Step-by-step explanation:
2(x - 1/2) = 3(5 - 2x) (distribute 2 and 3)
2x - 1 = 15 - 6x (add 6x on both sides)
8x - 1 = 15 (add 1 on both sides)
8x = 16 (divide both sides by 8)
x = 2

2(2 - 1/2) = 3(5 - 2(2)) (solve what's in parenthesis)
2(1.5) = 3(1) (distribute)

there are 8 elements in a set a, there are 5 elements in a set b, and 3 elements of those are shared both a and b. how many elements are in union of a and b?
There are 10 elements in the union of A and B.
What is the union of A and B?
The union of A and B will contain all of the elements found in either A or B or both sets. The union of sets is represented by the set notation. To find the union of two sets A and B, use the union B formula. Simply putting all of A and B's elements in one set and removing duplicates yields the union.So, set A has 8 elements and set B has 5 elements.
Both have 3 elements in common. So, 3 + (8 - 3) + (5 - 3) = 3 + 5 + 2 = 10Therefore, there are 10 elements in the union of A and B.

Please Help me !!!!!!!
Answer:
b and d I think are both right but if you can only pick one go with B
The measure that could be the side lengths of a right triangle is 30 cm, 72 cm, 78 cm, the correct option is B.
What is the right triangle?A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse. The angle of a right angle is always 90 degrees.
We are given that;
The right triangle
Now,
We can use this equation to test each option by plugging in the values and checking if they satisfy the equation.
A. 7 cm, 21 cm, 25 cm
7^2 + 21^2 = 25^2
49 + 441 = 625
490 = 625
False
This option does not satisfy the Pythagorean theorem, so it cannot be the side lengths of a right triangle.
B. 30 cm, 72 cm, 78 cm
30^2 + 72^2 = 78^2
900 + 5184 = 6084
6084 = 6084
True
Therefore, by right angle triangle the answer will be 30 cm, 72 cm, 78 cm.
