4 0

Answer:

-3, -1, 1

Step-by-step explanation:

The values of x when f(x) = 0 are the points on the graph when the curve intercepts the x-axis.

From inspection of the graph, the curve intercepts the x-axis at

x = -3, x = -1 and x = 1

Sam has 2 brothers. His brothers are 5 cm shorter and 7 cm shorter than him. Sam's height is 140 cm. What is the median height o

pochemuha

Answer:

The median height of Sam and his brothers is 135.

Step-by-step explanation:

First, let's find the age of Sam's brothers:

$B_{1} = 140 cm - 5 cm = 135 cm$

$B_{2} = 140 cm - 7 cm = 133 cm$

The median height of Sam and his brothers is given by the middle number of the three values arranged from lowest to highest:

133 <u>135</u> 140

<em>Since the middle number is 135, then the median height is 135. </em>

Therefore, the median height of Sam and his brothers is 135.

PLEASE HELP!!!!!! i will give brainiest!

mamaluj [8]

Answer:

$\sf B) \ y=-\dfrac{1}{5}x-4$

Explanation:

Equation: y = mx + b [where "m" is slope, "b" is y-intercept]

The y-intercept (b) is -4

$\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points$

Here take two points: (0, -4), (5, -5)

$\sf slope \ (m) : \dfrac{-5-(-4)}{5-0} = -\dfrac{1}{5}$

$\sf Hence \ equation : y = -\dfrac{1}{5} x -4$

Now multiply that result by 100 to convert to a percentage

0.4*100 = 40%

he has ridden 40% of the course so
