General regression equation :

y = mx + c

Where

y = predicted variable

x = predictor / explanatory variable

m = slope or gradient

c = Intercept

The regression equation obtained ;

ŷ = -0.08522X + 157.7779

To one decimal place :

ŷ = -0.1X + 157.8

The slope = - 0.1

Intercept = 157.8

Given the point (10, 25) and m = 2.5 , write the equation for the function m(t) point-stope form.

dalvyx [7]

Answer:

the equation for the function m(t) point-stope form will be:

$y - 25 = 2.5 (x - 10)$

Hence, option D is correct.

The graph is attached below.

Step-by-step explanation:

Given

Point (10, 25)

Slope m = 2.5

To determine

Write the equation for the function m(t) point-stope form.

We know that the point-slope form of the line equation is

$y-y_1=m\left(x-x_1\right)$

where

m is the slope of the line

(x₁, y₁) is the point

In our case:

m = 2.5

(x₁, y₁) = (10, 25)

substituting the values m = 2.5 and the point (10, 25) in the equation

$y-y_1=m\left(x-x_1\right)$

$y - 25 = 2.5 (x - 10)$

Therefore, the equation for the function m(t) point-stope form will be:

$y - 25 = 2.5 (x - 10)$

Hence, option D is correct.

The graph is attached below.

Need help with this question 2 + (4h- 1) = 13h Need All Steps Plz

vredina [299]

Answer and Step-by-step explanation:

For this equation, we are solving for h.

We are given the equation:

2 + 4h - 1 = 13h

First, we need to Simplify the equation.

2 - 1 + 4h = 13h

1 + 4h = 13h

Now, we need to Subtract 4h from both sides of the equation.

1 + 4h - 4h = 13h - 4h

1 = 9h

Finally, we Divide both sides by 9 to get h.

$\frac{1}{9} = h$

h is equal to $\frac{1}{9}$ .

To check your answer, we plug $\frac{1}{9}$ back into the given equation.

$2 + 4(\frac{1}{9} ) - 1 = 13(\frac{1}{9} )\\\\\\\\2 + \frac{4}{9} -1 = \frac{13}{9} \\\\\\1 = \frac{9}{9} \\\\1 = 1$

I hope this helps!
