Answer:

Equation of line in point slope form is:

y=-\dfrac{1}{5}(x+3)+2

Step-by-step explanation:

The point-slope form of the equation is:

y= mx + c

The equation of line passing through (a,b) and (c,d) is given by:

y-b=\dfrac{d-b}{c-a}(x-a)

firstly we find equation of line passing through (-3,2) and (2,1) and then convert it to point-slope form.

y-2=\dfrac{1-2}{2+3}(x+3)

y-2=-\dfrac{1}{5}(x+3)

y=-\dfrac{1}{5}(x+3)+2

Hence, Equation of line in point slope form is:

y=-\dfrac{1}{5}(x+3)+2

stiks02 [169]

Answer:

Check Explanation

Step-by-step explanation:

English Translation

In a report it is said that the predicted minimum temperature is -24 ° C and the maximum is -20 ° C. If the minimum temperature represents colder than the maximum temperature, should it not appear on the reverse? Explain your answer.

Solution

No, it shouldn't appear on the reverse. This is because, just as negative numbers work, they decrease, the further we move away from 0.

Celsius temperature scales are calibrated with respect to the freezing point of water. The freezing point of water serves as the reference point and is called the 0°C.

Temperatures higher than the freezing point of water taken on positive values and temperatures lower, take on negative values. The lower the temperature, the bigger the absolute value of the negative value is.

For example, just like In the question provided, -24°C represents a temperature that is 24° lower than the freezing point of water while -20°C represents a temperature that is 20° lower than the freezing point of water. It is evident that -24°C really is a lower temperature than -20°C.

Hope this Helps!!!

Purchased a vase and flowers at her local flower shop. At home, she wants to fill the cylindrical vase and at the
Paraphin [41]

Step-by-step explanation:

We know that

Radius = Diameter/2

=> Radius = 2/2

=> Radius = 1 in

Now,

Volume of cylinder = πr²h

=> π × (1)² × 9

=> 9π in³

Since it is filled ⅔ of the volume

So,

Water to be putted = ⅔ × 9π = 6π in³

ALGEBRA NATION Question 5 of 10 < Previous Question Next Question > Rewrite the expression below. -2a(a + b – 5) + 3(-5a +
Ierofanga [76]

–2a² + 4ab – 5a – 2b + b²

Solution:

Given data:

–2a(a + b – 5) + 3(–5a + 2b) + b(6a + b – 8)

<u>To solve this expression:</u>

Multiply each number or variable into the bracket.

–2a(a + b – 5) + 3(–5a + 2b) + b(6a + b – 8)

        = –2a² – 2ab + 10a – 15a + 6b + 6ab + b² – 8b

Arrange like terms together.      

       = –2a² – 2ab + 6ab + 10a – 15a + 6b – 8b + b²

       = –2a² + 4ab – 5a – 2b + b²

Hence the solution is  –2a² + 4ab – 5a – 2b + b².
