Answer:
B. The graph cross the y-axis at (0, 5), increasing from x = -10 to x = 2 and remaining constant from x = 2 to x = 10
Step-by-step explanation:
→Looking at the line as it increases, you can see that it intersects at the point of (0, 5) on the y-axis.
→The line on the graph is increasing from the point where x = -10, and stops at x = 2.
→The line then stays constant (basically meaning it doesn't increase/decrease, making it a horizontal line), strting from x = 2, to x = 10.
<u>Looking at the points above, you can determine that the correct answer is "B. The graph cross the y-axis at (0, 5), increasing from x = -10 to x = 2 and remaining constant from x = 2 to x = 10."</u>
Answer:
Rule is (x, y+k)
New point is (-3,9)
Step-by-step explanation:
A point translated vertically k units up means the x coordinate remains the same in the translation but the y coordinate is increased by k units
This can be represented mathematically as;
Let;s assume the point to be A with coordinates (x,y) then to get the image of the point under a vertical translation k units up you add k to the y coordinate value.
Given ;

where T is the translation
In the question
Given (-3,-6) and T is (0,5) the new coordinate will be

Step-by-step explanation:
Total no. of questions = 20
Marks given for a correct answer = 4
Marks deducted for a wrong answer = 1
No. of questions attended by the candidate = a
No. of questions the candidate gets correct = c
No. of questions the candidate gets wrong = a - c
Marks obtained for correct answers = 4c
Marks deducted for wrong answers = 1 (a - c)
Total marks scored by the candidate =
Marks obtained for correct answers - Marks deducted for wrong answers
Total marks scored by the candidate = 4c - 1 (a - c)
= 4c - a + c
= 5c - a
Answer:
C
Step-by-step explanation:
So we have:

To simplify, we can use the quotient rule of exponents, which says that if we have:

Then this equals:

So, our equation will be:

Subtract the exponents. Turn 1/5 into 2/10 by multiplying both layers be 2. Thus:

Subtract in the exponent:

So, our answer is C :)
Y = (-4/3)x that is the right answer
