Step-by-step explanation:
by inspection.. just looking at the graph
slope = - 1/2 (called m )
Y-intercept is at 1
line equation is then
y= mx + b
y= -1/2x +1

Determine whether each number is a solution of the
given inequality.
6-n > 11
when n = -5
O YES (n = -5 is a solution of the inequality)
O NO (n = -5 is not a solution of the inequality)
Answers
Answer:
NO (n = -5 is not a solution to the inequality).
Step-by-step explanation:
Given
[tex]6-n-6>11-6[/tex]
Subtract 6 from both sides
[tex]6-n-6>11-6[/tex]
Simplify
[tex]-n>5[/tex]
Multiply both sides by -1 (reverse the inequality)
[tex]\left(-n\right)\left(-1\right)<5\left(-1\right)[/tex]
Simplify
[tex]n<-5[/tex]
Therefore, n = -5 is NOT a solution of the inequality because 'n' must be less than -5.
Hence,
NO (n = -5 is not a solution to the inequality).
Verification:
Given
[tex]6-n-6>11-6[/tex]
substitute n = -5
6 - (-5) - 6 > 5
6+5-6 > 5
5 > 5

Which inequalities correctly show the relationship between the numbers 13, −4, and −17?
Answers
Answer:
13 > -17 < -4
Step-by-step explanation
13 = postive number
-17 and -4 = negtive.
13 is greater than -17
Since negtive is oppistie of postive it goes backwards.
So -4 is greater than -17

Answers
Answer:
We have a slope and a point, this way, we do not need to find the slope using two points. We can find the line using the Slope Form to turn it into Slope-Intercept Form, also known as "y = mx + b". We can use the Slope Form which is "y - y1 = m(x - x1)". A coordinate is "(x,y)", so that means, "(-1,4)" means that x = -1 and y = 4. We can substitute y1 for 4 and x1 for -1, and m for -5 since m is the slope. Plugging that information into the Slope Form Formula we get "y - 4 = -5(x - (-1))". We know that a negative with a negative turn positive, so we can use this information to change the formula to "y - 4 = -5(x + 1)". Now we distribute and simplify, these steps are shown below.
y - 4 = -5(x + 1)
y - 4 = -5x -5
y - 4 + 4 = -5x - 5 + 4
y = -5x - 1
Now that we have simplified it, we can see that the slope is -5 and the -1 is the y-intercept. To check this is a linear equation is to graph it, or substitute three x-coordinate or y-coordinates and draw a line. In conclusion, the equations is y = -5x - 1.

A student earns Php 280.00 for a 5 hour shift on his summer job. The amount
of money he earns varies directly to the number of hours worked. Find the
constant k, and the amount of money he will earn for an 8-hour shift.
Answers
Answer:
y=k5, 448 after an 8 hour shift
Step-by-step explanation:
The amount of money he will earn for an 8-hour shift is Php448
Let the amount of money he earns be A
Let the number of hours worked is "h"
If the amount of money he earns varies directly to the number of hours worked is expressed as:
A = kx
k = A/x
GIven that A = Php 280.00, x = 5 hours
k = 280/5
k = 56
If x = 8 hours, the amount of money A = kx
A = 56 * 8
A = Php448
Hence the amount of money he will earn for an 8-hour shift is Php448

A scuba diver descends below the surface of a lake at a rate of 12 feet per minute. What integer represents the depth of the diver after 4 minutes?
Answers
Since this scuba diver descends below the surface of a lake at a rate of 12 feet per minute, an integer which represents the depth of the diver after four (4) minutes is 48 feet.
What is the rate of change?The rate of change can be defined as a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.
Mathematically, the rate of change for the depth covered by this scuba can be calculated by using this formula;
Rate of change = Depth/time
Making depth the subject of formula, we have:
Depth = Rate of change × time
Substituting the given parameters into the formula, we have;
Depth = 12 × 4
Depth = 48 feet.
