Equation is equivalent to 4.5 = 2a?

1 answer:

7 0

Simplifying 4.5 = 2a

Solving 4.5 = 2a
Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.
Add '-2a' to each side of the equation. 4.5 + -2a = 2a + -2a

Combine like terms: 2a + -2a = 0 4.5 + -2a = 0

Add '-4.5' to each side of the equation.
4.5 + -4.5 + -2a = 0 + -4.5

Combine like terms: 4.5 + -4.5 = 0.0
0.0 + -2a = 0 + -4.5
-2a = 0 + -4.5

Combine like terms: 0 + -4.5 = -4.5
-2a = -4.5
Divide each side by '-2'.
a = 2.25
Simplifying
a = 2.25

Let's check: 2 x 2.25 = 4.5
Next time, follow these steps and you will pass

Find and sketch the domain of the function. f(x,y)=√(4-x^2-y^2) +√(1-x^2)

Answer:

Hello

Step-by-step explanation:

The domain is limited with 2 lines parallel: -1 ≤ x ≤ 1

and the disk ? (inside of a circle) of center (0,0) and radius 2

$dom\ f(x,y)=\{(x,y) \in \mathbb{R} ^2 | \ -1\leq x \leq -1\ and \ ( -\sqrt{4-x^2} \leq \ y \leq \sqrt{4-x^2}\ ) \ \}\\$

Answer:

600 m

Step-by-step explanation:

You know that she walks 1 meter in 1 second, but they're asking about minutes. Since 60 seconds are in 1 minute, it means she was 60 meters in 1 minute. Then multiply that by 10 (10 minutes).

She walked 600 meters, in 10 minutes.

I hope this helped!
