Solve for the negative solution: -2 | 5x - 1 | - 3 = - 11
The negative solution is [tex]-\frac{3}{5}[/tex]
First, add 3 on both sides.
[tex]-2|5x-1|=-8[/tex]
Then, Divide both sides by -2
[tex]|5x-1|=4[/tex]
We know 5x-1 = 4 or 5x-1=-4
[tex]x=1[/tex] (positive)
[tex]x=-\frac{3}{5}[/tex] (negative)

○ [tex]\displaystyle (2x + 1)(2x - 5) = 0[/tex]
Step-by-step explanation:
Find two quantities that when differed to 8, they also multiply to 20. Those will be 2 and 10. The TINIER quantity gets the plus symbol because the B-value is −8, therefore 10 gets the minus symbol, leaving 2 with the plus symbol. In extension, sinse we have a leading coefficient greater than one, we need to take extra procedures. Here is how it is done:
[tex]\displaystyle y = 4x^2 - 8x - 5 \\ \\ y = [4x^2 - 10x] + [2x - 5] \\ \:\:\:\:\:\:\:\:\:\:\:2x[2x - 5]+ 1[2x - 5] \\ \\ \boxed{[2x - 5][2x + 1] = 0}[/tex]

can you please help me it's really urgent
Answer:
D
Step-by-step explanation:
I is true. Limits don't care if the point defined or not. All they care about is if they are approaching a value from both sides, unequivocally.
II is not true. We need more information about the type of function.
III is true. Since the point isn't defined but the limit exist, we have a removable discontinuity

y= -2x +9 is an equation that represents a line parallel to the line 8x + 4y = 28 is the statement true or false? Be sure to explain your answer.
Answer:
True
Step-by-step explanation:
y = -2x + 9 is already in slope-intercept form, so we can leave it be. 8x + 4y = 28, however, is not, so we have to convert it to find the answer.
To do this we have to separate the variable 4y from the rest.
We get 4y = -8x + 28.
But, y must equal zero, so to achieve this, we divide the entire equation by 4.
Then we get y = -2x + 7
Since the slopes are the same (-2x = -2x) the lines are parallel.
Fred wants to determine the mean hourly wage of the working students at his
school. He asks thirty of his friends their hourly wages and calculates the sample
mean to be $8. Which of these statements MUST be true?
The sample was randomly selected.
Bias was present and the sample was not randomly selected.
The sample was representative of all students at the school
The mean hourly range of the working students at the school is $8.
Answer:
Last Option
Step-by-step explanation:
For this to be true, everyone who works at school must be getting a wage of 8$ so the hourly range of working students at the school IS 8$

The sum of two numbers that are at the ratio of 3:4 is 1001. Find these numbers.
Step-by-step explanation:
x - the part
3x one part(first number)
4x second part (second number)
so u have
3x + 4x = 1001
7x= 1001
x = 1001/7
x= 143. First number : 3x = 3• 143 = 429
Second number : 4x = 4• 143= 572
So, 429 and 572 are the numbers

sin2x= ____.
a. (1-cos2x)/2
b. sin^2xcos^2x
c. 2cos^2x-1
d. 2sinxcosx
The expression sin2x is a trigonometric expression
The equivalent of sin2x is (d) 2sinxcosx
How to solve the trigonometric expressionThe expression is given as:
sin2x
Rewrite properly as:
sin(2x)
To solve the expression, we make use of the following double angle ratio
sin(2a) = 2sin(a)cos(a)
Substitute x for a in the above equation
sin(2x) = 2sin(x)cos(x)
Rewrite the equation as
sin2x = 2sinxcosx
Hence, the equivalent of sin2x is (d) 2sinxcosx

The perimeter of a rectangular garden is 90m its breadth is 17m find its length
Answer:
28 m
Step-by-step explanation:
Length = x
90 = 2(17 + x)
17 + x = 90/2 = 45
so
x = 45 - 17 = 28 m
Two parallel lines are crossed by a transversal.
Parallel lines c and b are cut by transversal a. On line c where it intersects with line a, the uppercase left angle is 80 degrees. On line b where it intersects with line a, the bottom right angle is y degrees.
What is the value of y?
y = 40
y = 80
y = 100
y = 120
Answer 80
Step-by-step explanation:
If the line is a straight line through two parallel lines then the angles of the two intersections should be the same. Basically because they are both on the bottom right they will be the same.
The value of 'y' is 80 degrees. option B
How to determine the value of y
Note that alternate angles are equal
The intersections of a transversal with two parallel lines forms various types of pairs of angles such as
consecutive interior anglesconsecutive exterior angles, corresponding anglesalternate anglesIn this case, the transverse line forms alternate angles of line c and b
Angle at line c = 80 degrees
Angle at line b = y
Since they are alternate angles, y = 80 degrees
Therefore, the value of 'y' is 80 degrees. option B

An Egyptian fraction is the sum of distinct unit fractions. Here, we're asked to decompose 1/3 into an Egyptian fraction sum of two fractions. There are formulas available when the sum has a numerator value of 2.
Here, the sum is a unit fraction. A reasonable approach is to use 1/(n+1) as the larger portion of 1/n. Then the other portion is 1/(n(n+1)). That is effectively what we end up with here.

Multiplying by 3AB gives ...
AB = 3B +3A
Solving for B, we find ...
AB -3B = 3A
B(A -3) = 3A
B = 3A/(A -3)
In order for A-3 to be a factor of A, or equal to 3, we must have ...
A-3 = 1 ⇒ A = 4
A-3 = 3 ⇒ A = 6
A-3 = 3×3 ⇒ A = 4×3
This will give integer values for B when A is one of 4, 6, or 12. In the case of A=6, the two fractions are equal, which is not what you want
The two solutions are ...
