14x+63 , distribute the number to all the numbers inside
Student's error is –5 < x.
Solution:
Step 1: Given inequality
31 < –5x + 6
Step 2: Subtract 6 from both sides of the inequality.
31 – 6 < –5x + 6 – 6
25 < –5x
Step 3: Multiply both sides by –1 to reverse the inequality.
25 × (–1) > –5x × (–1)
–25 > 5x
Step 4: Divide by 5 on both sides.
–5 > x
The correct answer is –5 > x.
Student's error is –5 < x.
Answer:
the complete graph is in the image
Step-by-step explanation:
to plot this, plug in values of x and find y.
Answer:

Step-by-step explanation:
The equation of a line has the following format:

In which m is the slope and b is the y-intercept(value of x when y = 0).
In this question:
Slope 4, which means that
.
So

Contains point (1,-8).
This means that when
. We replace this into the equation to find b. So



So
