Answer:
B.
Step-by-step explanation:
To have a negative slope, <em>m</em> has to be negative. Any negative slope would show up as a negative coefficient in front of <em>x</em>.
Looks like 14.4 because you have to add them all together and divide by the total numbers
(20+22+10+5+15)/ 5
ANSWER: 77
Explanation: Making 88 in 8 minutes means that the machine is making 11 per minute thus being said if the machine worked for 7 minutes it would make 77 pens.
88/8=11
11*7=77
Solution: The another way to show the Fuaad's solution is
.
Explanation:
It is given that the solution of an inequality is
.
It can be break in two parts
and
.
The inequality
means the values of x is greater than
and the inequality
means the value of x is greater that than 7.
When we combine both results we get
it means the value of x is greater than 7.
It can also represented by number line as shown in given figure.
The number line shows the values of x and red lines shows the solution of both inequalities
and
.
The common region shows the combination of both the possible inequalities, therefore the another way to show the Fuaad's solution is
.
