Answer:

  k = 3.70

Step-by-step explanation:

Eliminate parentheses, then subtract the constant term on the left

  8.5 +4 -10k = -24.5

  -10k = -37 . . . . . . . . . . 12.5 subtracted from both sides

  k = 3.70 . . . . . . . . . . . both sides divided by -10 (no rounding required)

PLEASE HELP A QUESTION OF LIFE OR DEATH!!!!!!!
Ira Lisetskai [31]

Answer:  The length of the third straw is 29 centimeters.

Step-by-step explanation:  Given that Anja is creating a triangle using three straws and the lengths of two shorter straws are 20 cm and 21 cm.

We are to find the length of the third straw in centimeters so that Anja will create a right triangle.

The two shorter straws will make the legs of the right-angled triangle because they are shorter.

Since the third straw will be the largest, so it will make the HYPOTENUSE of the triangle.

In a right-angled triangle, we have

Hypotenuse² = length of one leg² + length of the other leg².

Therefore, we get

Hypotenuse^2=20^2+21^2=400+441=841\\\\\Rightarrow Hypotenuse=29.

Thus, the length of the third straw is 29 centimeters.

A bakery sells 3642 pastries in 2010. The bakery sells 8422 pastries in 2015. Write a linear model that represents the number y​
Simora [160]

Answer:

y = 936x + 3742

Step-by-step explanation:

If it is a linear model, then we should have a slope and y-intercept with the equation representing the model as;

y = mx + c

where m is the slope and c is the y-intercept

Thus, we have for the slope;

(8422-3742)/(2015-21010) = 4680/5 = 936

So the equation will be;

y = 936x + c

To get c , we can use the years after 2010 which is 2015 in this case

8422 = 936(5) + c

c = 8422- 4680

c = 3742

So the linear model is;

y = 936x + 3742

State the slope and y-intercept of the graph y = 3x - 10.
Firlakuza [10]

Answer:

The slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept. Using the slope-intercept form, the slope is 3 .
