Answer:
( − ∞ , ∞ ) hope i help
Step-by-step explanation:
First, solve each inequality. I'll solve the first one first.
7 ≥ 2 x − 5
12 ≥ 2 x
6 ≥ x
Therefore, x could be any number less than or equal to 6. In interval notation, this looks like:
( − ∞ , 6 ]
The parenthesis means that the lower end is not a solution, but every number above it is. (In this case, the lower end is infinity, so a parenthesis must be used, since infinity is not a real number and so it cannot be a solution.) The bracket means that the upper end is a solution. In this case, it indicates that not only could
x
be any number less than 6, but it could also be 6.
Let's try the second example:
3 x − 2 4 > 4
3 x − 2 > 16 3 x > 18 x > 6
Therefore, x could be any number greater than 6, but x couldn't be 6, since that would make the two sides of the inequality equal. In interval notation, this looks like:
( 6 , ∞ )
The parentheses mean that neither end of this range is included in the solution set. In this case, it indicates that neither 6 nor infinity are solutions, but every number in between 6 and infinity is a solution (that is, every real number greater than 6 is a solution).
Now, the problem used the word "OR", meaning that either of these equations could be true. That means that either x is on the interval ( − ∞ , 6 ] or the interval ( 6 , ∞ )
. In other words, x
is either less than or equal to 6, or it is greater than 6. When you combine these two statements, it becomes clear that
x
could be any real number, since no matter what number
x
is, it will fall in one of these intervals. The interval "all real numbers" is written like this:
( − ∞ , ∞ )
Which sign makes the statement true is 1<,>,or =to -8
Step-by-step explanation: the greater than sign because 8 is greater than 1 boom there u go
8x-2=-947x
What does X stand for ?
Answer:
-7
Step-by-step explanation:
1st, regroup terms.
8x-2 = 7x -9
Next, subtract 7x from both sides.
8x-2-7x = -9
Next, Simplify 8x-2-7, to -2.
x-2 = -9
Add 2 to both sides.
x = -9 + 2
Simplify −9+2 to −7.
Find a · b.
a = −5, 1 / 2 ,
b = −5, 6
Answer:
a · b = 28 units
Step-by-step explanation:
Given vectors
a = (-5, 1/2)
b = (-5, 6)
The scalar or dot product of the two vectors, given by a · b is
a · b = (-5, 1/2) · (-5, 6)
To solve this, multiply the first term in a with the first term in b and add the result to the product of the second term in a and the second term in b. i.e
a · b = (-5 x -5) + (1/2 x 6)
a · b = 25 + 3
a · b = 28
Therefore, the dot product of a and b is
a · b = 28 units
In circle V. r= 14ft.
What is the area of circle V?
14Tr ft2
28tt ft2
49tt ft2
196 ft2
Radius of circle = 14ft
We have to find the area of circle[tex].[/tex]
Area of circle of radius R is given by
A = π × R²⇒ A = π × R²

It takes a thermal drill 13 minutes to bore a hole -39 feet from ground level into a glacier. What is the change in depth after one minute?
Answer:
3 feet
Step-by-step explanation:
39 divided by 13 = the unit rate per min.
39 divided by 13 = 3
Answer:
-3 feet
Step-by-step explanation:
Divide -39 by 13, since it takes 13 minutes to dig -39 feet:
-39/13
= -3
So, the change in depth after one minute is -3 feet

#4. Identify the conclusion of the conditional statement: "I must reset the
clock if it's Daylight Saving time."*
A- I must reset the clock
B-It's Daylight Saving time
C-There is not conclusion
Answer:
C-There is not conclusion
Step-by-step explanation:
In a conditional statement, there is a hypothesis and a conclusion. It is usually symbolized or represented by " If X, then Y." It is an if - then statement.
Here, the statement "X" is called the hypothesis and the statement "Y" denotes the conclusion. The conclusion is true if the hypothesis is true.
The conclusion of any conditional statement is the immediate phrase that follows the word 'then'.
In the context, the sentence "I must reset the clock if it's Daylight Saving time." , the word 'then' is not there, so we can say that there is no conclusion in the statement.

what is the slope of the line below -3,2 3,2
a. negative
b.undefined
c. positive
d.zero
Answer:
0
Step-by-step explanation:
let (-3,2) be (x1,y1)
and(3,2)be(x2,y2)
Now,
slope = y2-y1/x2-x1
=2-2/3-(-3)
=0/3+3
=0/6
therefore slope=0

Write y+1=-2x-3 in standard form
Answer:
y=2x-4
Step-by-step explanation: this looks alot like an equation for slope is it?
Answer:
-2x - y = 4
Step-by-step explanation:
Standard Form: Ax + By = k
Note that while k is a variable, it stands for constant, which means the number with no variables attached would fill in the space. Isolate the constant. Subtract y, and add 3 to both sides:
y + 1 = -2x - 3
y (-y) + 1 = -2x - 3 (-y)
1 = -2x - 3 - y
1 = -2x - 3 - y
1 (+3) = -2x - 3 (+3) - y
4 = -2x - y
Set the equation so that it looks like the standard form equation given above:
-2x - y = 4 is your answer.

ej bisects def, m dej-5x+7, m JEF=8x-8. find x
Answer:
x = 5
Step-by-step explanation:
The information given has been sketched out in the attachment below.
Line segment EJ is an angle bisector of angle DEF. Therefore, m<DEJ = m<JEF.
The equation to find x would be expressed as follows:
5x + 7 = 8x - 8
Subtract 5x from each side (subtraction property of equality)
5x + 7 - 5x = 8x - 8 - 5x
5x - 5x + 7 = 8x - 5x - 8
0 + 7 = 3x - 8
7 = 3x - 8
Add 8 to both sides of the equation (addition property of equality)
7 + 8 = 3x - 8 + 8
15 = 3x
Divide both sides by 3
15/3 = 3x/3
5 = x
x = 5
