Answer:
x² + 4x - 21
Step-by-step explanation:
Given the solutions of x = 3 and x = -7, moving the constant to the other side and setting both equations equal to '0':
x - 3 = 0 and x + 7 = 0
So, the two binomials that make up the quadratic are:
(x - 3)(x + 7)
Use FOIL: x² + 7x - 3x - 21
Combine like terms: x² + 4x - 21
Answer:
$15.9
Step-by-step explanation:
148*15=2220
2220/500=4.44 (=5 because you can only buy paper 500 pages a time)
5*3.18=15.9
Therefore, the answer is $15.9
Answer:
7.0?
Step-by-step explanation:
49/7 would be 7, If the question was 7/49 the answer would be 0.14285714285 (a decimal)
(-5, 3), left 5 up 3.
(-3, 5), left 3 up 5
(0, -1) down 1
(1, 2) right 1 up 2
(4, 5) right 4 up 5
This relation will pass the vertical line test and will therefore be a function.
