Answer:
x = 
Step-by-step explanation:
Given
ax - c = bx + d ( collect the terms in x together )
Subtract bx from both sides
ax - bx - c = d ( add c to both sides )
ax - bx = c + d ← factor out x from each term on the left side
x(a - b) = c + d ← divide both sides by (a - b )
x =
Answer:
y = 2x^2 + 4x - 2
Step-by-step explanation:
y=2(x+1)^(2)-4 is in vertex form. We want the same equation in standard form, which looks like y = ax^2 + bx + c.
Perform the indicated multiplication (squaring of x + 1):
y = 2(x^2 + 2x + 1) - 4, or
y = 2x^2 + 4x + 2 - 4, or
y = 2x^2 + 4x - 2 This is in the standard form of a quadatic.
Answer:
$15.21
Step-by-step explanation:
17% of $13=0.17*13=2.21
13 (the price of the actual lunch) +2.21= 15.21
Alternatively, you can just do the operation:
13*(1+0.17)=15.21
This is because 1*13=the price of the actual lunch and 0.17*13=the price of the tip
X = 4, -2
i’m not sure if that’s the answer you’re looking for but i can help you find another way!
