2.5% of what is 2.21?

Varvara68 [4.7K]

To get the answer do this:

2.5% of what is 2.21

2.5%x = 2.21

2.5/100x = 2.21

0.025x = 2.21

divide both sides by 0.025

0.025x/0.025 = 2.21/0.025

What are the intercepts of y=4x-2

Lemur [1.5K]

Answer:

To find the x-intercept, make y equal to zero, and solve for x. To find the y-intercept, make x equal to zero, and solve for y.

Explanation:

y=4x−2

X-Intercept

0=4x−2

Add 2 to both sides of the equation.

2=4x

Divide both sides by 4.

2/4=x

Simplify.

1/2=x

Switch sides.

x=1/2

Y-Intercept

y=4(0)−2

y=−2

What is the derivative of 3x+5x

Vaselesa [24]

Answer:

$\displaystyle \frac{d}{dx}[3x + 5x] = 8$

General Formulas and Concepts:

Calculus

Differentiation

Derivatives
Derivative Notation

Derivative Property [Multiplied Constant]: $\displaystyle \frac{d}{dx} [cf(x)] = c \cdot f'(x)$

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle y = 3x + 5x$

Step 2: Differentiate

Simplify: $\displaystyle y = 8x$
Derivative Property [Multiplied Constant]: $\displaystyle y' = 8\frac{d}{dx}[x]$
Basic Power Rule: $\displaystyle y' = 8$
