Answer:
b
Step-by-step explanation:
In the question it says 25%, thus making it clear that b is the answer because percentages can be rearranged into decimals by placing a point two spaces left of the number.
Answer:
B
Step-by-step explanation:
A function is happens when each input only has one output. In this table 4 and 5 have the same output, therefore this is not a function.
Answer:
x = -7
, y = 0
Step-by-step explanation:
Solve the following system:
{4 x + 5 y = -28 | (equation 1)
-4 x - 7 y = 28 | (equation 2)
Add equation 1 to equation 2:
{4 x + 5 y = -28 | (equation 1)
0 x - 2 y = 0 | (equation 2)
Divide equation 2 by 2:
{4 x + 5 y = -28 | (equation 1)
0 x - y = 0 | (equation 2)
Multiply equation 2 by -1:
{4 x + 5 y = -28 | (equation 1)
0 x+y = 0 | (equation 2)
Subtract 5 × (equation 2) from equation 1:
{4 x+0 y = -28 | (equation 1)
0 x+y = 0 | (equation 2)
Divide equation 1 by 4:
{x+0 y = -7 | (equation 1)
0 x+y = 0 | (equation 2)
Collect results:
Answer: {x = -7
, y = 0
Answer:
4
Step-by-step explanation:
solve for x by simplifying both sides of the equation then isolating the variable
Answer is 27
2(4) + 3 + (4*4) = 8 + 3 + 16= 27
