Answer:
Equivalent
Step-by-step explanation:
2(x-3)
2 times x=2x-3
So equal
The equation of the function would be:
B. f(x)=4x+4, because if x=2, and if the answer is 12, 12 divided by 2 is 6, so f=6 4 multiplied by 2 is 8 added by 4 is 12. The equation in numbers would be 6(2)=12 or 6(2)=4(2)+4 which ends up being 12=12.

Step-by-step explanation:
The given quadratic equation is expressed as
x² = 5 - x
Rearranging the equation to take the standard form of ax² + bx + c, it becomes
x² + x - 5 = 0
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 1
b = 1
c = - 5
Therefore,
x = [- 1 ± √(1² - 4 × 1 × - 5)]/2 × 1
x = [- 1 ± √(1 - - 20)]/2
x = [- 1 ± √21]/2
x = (- 1 + √21)/2 or x = (- 1 - √21)/2
Answer:
Step-by-step explanation:
Slope = (y2 -y1)/(x2-x1)
y2 = 800, y1 = 400, x2= 4, x1= 2
Slope = (800-400)/(4-2)
= 400/2
= 200calories/hr
Answer:
12 1/2
Step-by-step explanation:
2 x 5 = 10
1/2 x 5 = 2 1/2
10 + 2 1/2 = 12 1/2
