Compare the process of solving
|x - 11 + 1 < 15 to that of solving
|x - 11 + 1 > 15.
Answer:
I have solved them but I don't know what to o next
Step-by-step explanation:
1) lx- 11+ 1< 15
+11 on both sides
lx+ 1< 26
-1 on both sides
lx< 25
2) lx-11+1>15
+11 on both sides
lx+1>26
-1 on both sides
lx> 25
Answer:
Both absolute values would need to be isolated first.
You would need to write a compound inequality for each.
Both compound inequalities would compare
x – 1 to –15 and 15.
The inequality with “<” would use an “and” statement, while the “>” would use an “or” statement.

Jeremy has heard a lot of people in the club talking about tackling a 950-foot rock formation. Jeremy has set a limit that they won’t climb anything that takes longer than 7 hours, so they have enough time to travel to and from the place. Will it be possible to climb a 950-foot rock formation within Jeremy’s time constraint? Explain why or why not.
Answer:
Depends on how fast they climb. If we knew how fast they climb then we can tell, but without knowing how fast they climb we can't tell.

A restaurant has 44 waiters on permanent staff. It hires some temporary waiters during busy times of the year. Let t represent the number of temporary waiters and w represent the total number of waiters. Find the value of w when t=5.
Step-by-step explanation:
Since Total workers = Permanent + Temporary workers,
w = 44 + t.
Hence when t = 5, w = 44 + 5 = 49.
What is the gradient of the straight line 2y = -3x - 8 ?
Answer:
- [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope (gradient) and c the y- intercept )
Given
2y = - 3x - 8 ( divide all terms by 2 )
y = - [tex]\frac{3}{2}[/tex] x - 4 ← in slope- intercept form
with gradient = - [tex]\frac{3}{2}[/tex]
The gradient of the straight line 2y = -3x - 8 will be -1.5.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0.
The slope(gradient) 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that the equation of the line is, 2y = -3x - 8
Rearrange the equation in the standard form of the equation as
2y = -3x - 8
y=-3/2 x-8/2
y= -1.5x - 4
Compare the obtained equation with the standard equation,y=mx+b. Where m is the gradient of the straight line.
m= -1.5
Thus, the gradient of the straight line 2y = -3x - 8 will be -1.5.

Find the sum

A car is traveling at 45 miles per hour. Once the car starts to brake, it's speed (s) is related to the number of seconds (t) it spends braking according to the formula shown below. s=10t+45
Determine how many seconds it takes for the car to stop.
Answer: 55t
Step-by-step explanation:
The time taken by the car to stop is 1.28 seconds.
What is speed?Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.
Given that a car is travelling at 45 miles per hour. Once the car starts to brake, its speed (s) is related to the number of seconds (t) it spends braking according to the formula shown below. s=10t+45.
The formula to calculate the speed is written as,
V = s / t
Here s = 10t + 45 substitutes the value in the formula and calculate the time,
45 = ( 10t + 45 ) / t
45t = 10t + 45
35t = 45
t = 45 / 35
t = 1.28 seconds

What is the slope of the line 4x - 8y = 16 ?*
Step-by-step explanation:
4x - 8y = 16
8y = 4x - 16
y = 0.5x - 2
Hence the slope is 0.5.
Answer:
1/2
Step-by-step explanation:
Slope from a standard form equation is [tex]-\frac{A}{B}[/tex].
A is 4 and B is -8.
[tex]-\frac{A}{B}=\frac{-4}{-8}= \boxed{\frac{1}{2}}[/tex]

What are simultaneous equation ?"Simultaneous Equation is an essential Chapter in the Algebra branch of Mathematics. There are times when you come across two or more unknown quantities and two or more equations relating to them. These are called Simultaneous Equations. When you are asked to solve such equations, you must find values of the unknowns which satisfy all the given equations at the same time. They are Simultaneous Equations because the equations are solved at the same time. Simultaneous Equations need algebraic skills to find the values of letters within two or more equations."

The difference between two num-
bers is 24. What are the numbers
if their sum is 78?
(Please help me!)
Answer:
51 and -27
Step-by-step explanation:
The sum of two numbers is 24 and their difference is 78. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 24. In other words, x plus y equals 24 and can be written as equation A:
x + y = 24
The difference between x and y is 78. In other words, x minus y equals 78 and can be written as equation B:
x - y = 78
Now solve equation B for x to get the revised equation B:
x - y = 78
x = 78 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 24
78 + y + y = 24
78 + 2y = 24
2y = -54
y = -27
Now we know y is -27. Which means that we can substitute y for -27 in equation A and solve for x:
x + y = 24
x + -27 = 24
X = 51
Summary: The sum of two numbers is 24 and their difference is 78. What are the two numbers? Answer: 51 and -27 as proven here:
Sum: 51 + -27 = 24
Difference: 51 - -27 = 78
Answer:
The numbers are 27 and 51
Explanation
x - y = 24
x + y = 78
Add together the equations
2x = 102
x = 51
Put into equation
51 - y = 24
27 = y

A back patio has 127ft^2127 f t 2 of area in Brad's yard. If his patio is perfectly square, what is the side length of the patio? Round your answer to the nearest hundredths place. Group of answer choices 11.27 feet 11.3 feet 11 feet 11.25 feet
Answer:
The length of side of patio is 11.27 feet.
Option A is correct option.
Step-by-step explanation:
Area of patio = 127 ft^2
We need to find side length of the patio.
Since the patio is square, the formula used is:
[tex]Area\: of\: square = l^2[/tex]
where l is the side length of square.
Now, putting value of area we can find area of square.
[tex]Area\: of\: square = l^2\\127=l^2\\Switching\:sides\:\\l^2=127\\Taking\:square\:root\:on\:both\:sides\\\sqrt{l^2}=\sqrt{127} \\l=11.27[/tex]
So, the length of side of patio is 11.27 feet.
Option A is correct option.
A)7 in.
B)148 in.
C)92 in.
D)168 in.
