Answer:
2x - 2y
Step-by-step explanation:
P = 7x + 2y
P =a + b + c
7x + 2y = 2x + y +3x - 5y + c
7x + 2y - 5x - 4y
= 2x - 2y
$80
She must draw out more than the purchase price of $69
Since she can only withdraw multiples of $20
then she would have to withdraw 4 lots of $20 = $80
Answer:
(-5,-37)
Step-by-step explanation:
While the standard quadratic form is a x 2 + b x + c = y , the vertex form of a quadratic equation is y = a ( x − h ) 2 + k . In both forms, y is the y -coordinate, x is the x -coordinate, and a is the constant that tells you whether the parabola is facing up ( + a ) or down ( − a ).
Answer:
Option C
Step-by-step explanation:
From the number line given in the picture,
Blue arrow has the starting point at a = 6 (Dark point) and moving towards negative side of the number line.
Therefore, number line represents a ≤ 6
3a ≤ 3(6)
3a ≤ 18
3a - 11 ≤ 18 - 11
3a - 11 ≤ 7
Therefore, Option C is the correct option.
