1 answer:

3 0

Answer:
exponential

Step-by-step explanation:
An exponential function is defined as a function with a positive constant other than 1 raised to a variable exponent. A function is evaluated by solving at a specific input value. An exponential model can be found when the growth rate and initial value are known.

Verizon [17]

Answer:

Slope: $-\dfrac{1}{2}$

Equation: $y=-\dfrac{1}{2}x+8$

Step-by-step explanation:

The line of the best fit passes through the points (0,8) and (4,6).

If the line passes through the points $(x_1,y_1)$ and $(x_2,y_2)$ then the slope of the line is

$\dfrac{y_2-y_1}{x_2-x_1}$

Hence, the slope of the line of the best fit is

$\dfrac{6-8}{4-0}=\dfrac{-2}{4}=-\dfrac{1}{2}$

The equation of the line is

$y=mx+b,$

where m is the slope and b is y-intercept, so the equation of the line of the best fit is

$y=-\dfrac{1}{2}x+8$

A triangle has one angle measuring 3x degrees. A second angle measures 2x + 20 degrees and the third angle measures 4x -20 degre

Maurinko [17]

All the interior angles of a triangle always add up to 180 degrees.

3x + (2x + 20) + (4x - 20) = 180
3x + 2x + 20 + 4x - 20 = 180
3x + 2x + 4x + 20 - 20 = 180
10x = 180
x = 180/10
Therefore, x = 18

Answer:

Step-by-step explanation:

$y = \frac{-1}{5}x - 4\\\\Plugin x = 0 , y = 0 - 4\\\\ y = -4\\\\(0 , -4)\\\\Plugin x = 5, y =\frac{-1}{5}*5-4 = -1-4=-5\\\\(5 , -5)\\\\Plugin x = -5, y =\frac{-1}{ 5}*(-5)-4=1 - 4 = -3\\(-5, -3)$

Plot the points(0 ,-4) , (5 , -5) and (-5 , -3 ) in the graph and join the points.

Mandarinka [93]

Answer:

The equation is 0.11x + 0.25 = 0.15x (I think) and the answer is 6.25 = x

Step-by-step explanation:

0.11x + 0.25 = 0.15x Subtract 0.11x from both sides

-0.11x -0.11x

0.25 = 0.04x Divide both sides by 0.04

6.25 = x
