Answer:
12x-4
Step-by-step explanation:
15x*
5/4=12x
-5*4/5=4
Add the two together and you get
12x-4
Please use " ^ " to denote exponentiation: <span>f(x) = 4x^2 + 2x -5. To find the vertex form of this equation, complete the square:
f(x) = 4x^2 + 2x - 5
= 4(x^2 + (2/4)x) - 5
= 4(x^2 + (1/2)x ) -5
= 4(x^2 + (1/2)x + 1/16 ) - 4/16 - 5
= 4(x+1/4) - 21/4 <= in vertex form
Here h= -1/4 and k = -21/4. The vertex is at (-1/4, -21/4)</span>
Answer:
x = 0
y = 3.5
Explanation:
x + 5y = 16 x + 3y = 10
-x -x
5y = 16 3y = 10
5 x 3.5 = 16 3 x 3.5 = 10
Y=2x+10
That is the eqasion, 2(it is the cost per card) and multpy be how many cards you want, then add 10 as base fee
Answer:
y = 1/2x + 7
Step-by-step explanation:
y = mx+ b
y = 5
x = -4
5 = 1/2(-4) + b
5 = -2 + b
7 = b
