How do u write an equation in standard form containing the points (0,2) and (-4,1)

-Dominant- [34]

Answer:

y=1/4+2

Step-by-step explanation:

If we're using y=mx+b, then m is the slope and b is the y intercept. The slope of the two points provided, is 1/4. The y intercept, is two.

What equation represents the model shown below?

g100num [7]

Given:

The algebra tiles of an equation.

To find:

The equation represented by the given model.

Solution:

On the left side of the model we have 4 tiles of (-x) and 3 tiles of (-1). So,

$LHS=(-x)+(-x)+(-x)+(-x)+(-1)+(-1)+(-1)$

$LHS=-4x+(-3)$

$LHS=-4x-3$

On the right side of the model we have 8 tiles of (-1). So,

$RHS=(-1)+(-1)+(-1)+(-1)+(-1)+(-1)+(-1)+(-1)$

$RHS=-8$

Now, equate the LHS and RHS to get the equation.

$-4x-3=-8$

Therefore, the equation for the given model is $-4x-3=-8$ .

Using a formula estimate the body surface area of a person whose height is 150 cm and who weighs 80 kg.

ladessa [460]

Answer:

B. $1.83\text{ m}^2$

Step-by-step explanation:

We are asked to find the body surface area of a person whose height is 150 cm and who weighs 80 kg.

$\text{Body surface area}( m^2)=\sqrt{\frac{\text{Height (cm)}\times \text{Weight (kg)}}{3600}}$

Substitute the values:

$\text{Body surface area}( m^2)=\sqrt{\frac{150\text{ cm}\times 80\text{(kg)}}{3600}}$

$\text{Body surface area}( m^2)=\sqrt{\frac{12,000}{3600}}$

$\text{Body surface area}( m^2)=\sqrt{3.3333333}$

$\text{Body surface area}( m^2)=1.825741$

$\text{Body surface area}( m^2)=1.83$

Therefore, the body surface area of the person would be 1.83 square meters.
