Answer:
Change the equation to the slope intercept form (y = mx + b)
2y = 6x + 8
Divide equation by 2
y = 3x + 4
Therefore
The line as a y intercept of 4
:
Parallel lines have the same slope;
Find the slope by putting in the equation in the point/intercept form
4x + 4y = 20
4y = -4x + 20
Divide equation by 4, results
y = -1x + 5
:
Now we know the slope (-1) and the y intercept (+4) if the line
y = -1x + 4
or just
y = -x + 4 is "the line"
Step-by-step explanation:
Answer: x = - 4
Step-by-step explanation:
7-2x=1
PEMDAS
so add 7 to both sides
-2x=8
divide by -2 from both sides
x=-4
SOLUTION
Given the question in the image, the following are the solution steps to answer the question
STEP 1: Write the given details

STEP 2: Get the number of students that takes the subjects only
From the basic stuff, we have Number of candidates who had taken only each of the subjects

STEP 3: Represent the values above on a Venn Diagram after getting the values
STEP 4: Find the total number of candidate that sat for the exam.

Hence, the total number of candidates that sat for the exam is 276
C. 49 is the answer i believe.
