Answer:
D. 2x + y = -4
Step-by-step explanation:
Standard form for the equation of a line is Ax + By =C where A is a positive integer and B and C are integers
y + 1 = -2x - 3
Add 2x to each side
2x+y + 1 = -2x+2x - 3
2x+y +1 = -3
Subtract 1 from each side
2x+y +1-1 = -3-1
2x+y = -4
for a power of ten all you need is just add a zero, example, 10 to the power of 10 just add ten zeros behind the 10 -------> 100,000,000,000
Answer:
p = 0.11 (rounded to 2 DP)
p = 0.111 (rounded to 3DP)
Step-by-step explanation:
p = 0.48³
p = 0.110592
Rounded to 2 DP
p = 0.11
Rounded to 3DP
p = 0.111
Eliminate parentheses using the distributive property.
... 5x = 10x -10x +15
Collect terms, then divide by the coefficient of x.
... 5x = 15
... x = 3
