Answer:
0.1671 or 16.7%
Step-by-step explanation:
Original cost: $3.59
Inflated cost: $4.19
$4.19 - $3.59 = $0.60
$0.60 / $3.59 = 0.1671 ---> 16.7%
Answer:
x + 7
Step-by-step explanation:
x^2 + 4x − 21 =
= (x + 7)(x - 3)
x^2 + 11x + 28 =
= (x + 4)(x + 7)
Answer: x + 7
, so corresponding sides occur in some ratio with one another. In particular, the order the vertices tells you that
Answer:
x= -10
Explanation:
When solving for x with 2 equations given, you’d add 3x+10 with 7x-30 like so: 3x+10=7x-30. you ALWAYS work your way from right to left till you’ve got nothing on your right but a number with no variable, so subtract 7x with 3x, giving you 4x, so now your equation would be: 4x+10=-30. Now that there is a single number to the right, you start to rotate, so subtract 10 from -30, giving you -40, so now your equation would be: 4x=-40. This is the last step, so all you have to do is divide 4x to itself and to -40. You DO NOT add the variable x to your answer, so it should be: x=-10 as your final answer.
