c)
Step-by-step explanation:
Use 49 instead of 14 for 7²
Reason: 7² = 7 * 7 = 49
Not 14 as 7*2 = 14
Answer:
y = -2x - 6
Step-by-step explanation:
Find the gradient: y difference/x difference
0 - (-6) / -3 - 0
6 / -3
= -2
y = mx + c
-6 = -2 × 0 + c
-6 = c
= C = -6
Answer:
v = 120
Step-by-step explanation:
If v is inversely proportional to square root of d, then we can write
= k
If v = 30 and d = 400, then
30(
) = k
k = 30(20) = 600
Now
= 600
If d = 25, then v
= 600
5v = 600
v = 120
Answer:

Step-by-step explanation:
To solve this problem, first you have to isolate it on one side of the equation.
First, subtract 1/4 from both sides.
1/4+x-1/4<5/6-1/4
Solve.
5/6-1/4=7/12
Therefore, the correct answer is A. x< 7/12.
