1/2 + 1/2 is 1
Also you can do it as 0.5 + 0.5 = 1.0

Write the equation of the line in fully simplified slope-intercept form.

PtichkaEL [24]

Answer:

Consider points (0, -5) and (-6, -1)

» General equation of a line:

${ \tt{y = mx + c}}$

m is slope
c is y-intercept

 Slope (m):

${ \tt{m = \frac{ - 1 - ( - 5)}{ - 6 - 0} }} \\ \\ { \tt{m = \frac{4}{ - 6} }} \\ \\ { \tt{m = - \frac{2}{3} }}$

 y-intercept (c):

${ \tt{y = mx + c}}$

consider point (0, -5)

${ \tt{ - 5 = c}} \\ { \tt{c = - 5}}$

Equation:

${ \boxed{ \tt{y = - \frac{2}{3} x - 5}}}$

Isaiah walks 3 miles due north, turns and then 5 miles due east. How far is he from his starting point?

Sonbull [250]

Isiah is 5.83 miles away from his starting point.

When you draw the the miles Isaiah walks, you will discover that you are forming a right angle triangle.

To measure the length from the starting point to the ending point. We must used the Pythagorean equation. Where in the square of the hypotenuse is equal to the sum of squares of the other two sides.

a² + b² = c²

a = 3 miles 3² + 5² = c²
b = 5 miles 9 + 25 = c²
c = hypotenuse. 34 = c²

We must get the hypotenuse, since 34 is the square of the hypotenuse we must look for its square root.

c² = 34
c = √34
c = 5.83 miles

During a cold winter, the temperature stayed below zero for 10 days (ranging from −20 to −5). The variance of the temperatures o

Serjik [45]

Answer:

The variance of the temperatures of the 10 day period must be at least zero.

Step-by-step explanation:

The variance is the expectation of the squared deviation of a random variable from its mean. It measures how far a set of numbers are spread out from their average value.

Its unit of measure corresponding to the square of the unit of measure of the variable. In this case, the variance of the temperatures is expressed in (°C)². The variance has a minimum value of 0.

Since the variance is squared, it will always have values greater than zero.

The image of the point (-6, -2)under a translation is (−7,0). Find the coordinates of the image of the point (7,0) under the sam

lesya692 [45]

Answer:

hello : solutio ( 6 ; 2)

Step-by-step explanation:

the translation is : x' = x + a ....(*)

y' = y + b ...(**)

calculate the coordinates ( a ; b) of vectro by the translation

you have : x' = -7 y' = 0 x = -6 y = -2

Substitute in (*) , (***) : -7 = -6 +a

0 = - 2 + b

a = -1 and b= 2

so : x' = x - 1

y' = y + 2

calculate now the coordinates of the image of the point (7,0) under the same translation.

x = 7 and b = 0

so : x' = 7-1 = 6 and y' = 0 + 2 = 2

the image is : ( 6 ; 2 )
