Mathematics
1 answer:
lesantik [10]3 years ago

Answer:

y = -3x + 9

Step-by-step explanation:

y = mx + b where m is the slope and b is the y intercept

The hypotenuse is on the same line as BC but twice as long.  So extend that line up and it will cross the y axis at (0,9).  9 will be your y intercept.

To find the slope start at C and count  up 9 and to the left 3 to get to B.

So the slope is rise/run or 9/(-3) = -3.

Final equation would be y = -3x + 9

Crystal has three packages of drink mix and two bottles of lemonade each package makes 64 oz of lemonade each bottle contains 48
irakobra [83]

Number of glass can serve is 48 glass

<u>Given:</u>

Number of drink mix package = 3

Quantity of each package = 64 oz

Number of lemonade bottle = 4

Quantity of each lemonade bottle = 48 oz

Quantity of each glass = 6 oz

<u>Find:</u>

Number of glass can serve

<u>Computation:</u>

Total quantity of mix drink = 3 × 64

Total quantity of mix drink = 192 oz

Total quantity of lemonade = 2 × 48

Total quantity of mix drink = 96 oz

Total drink = 192 + 96

Total drink = 288 oz

Number of glass can serve = Total drink / Quantity of each glass

Number of glass can serve = 288 / 6

Number of glass can serve = 48 glass

Find the sum and product of zeroes of the quadratic polynomial 3x² + 5x-2.​
Alex17521 [72]

Answer:

see first of all it is a quadratic polynomial so it will have 2 zero alpha and beta

now , we will find value of a , b, c

so,

a= 3

b= 5

c= -2

now, sum of the zeros ( alpha + beta) =-b/a

so,-5/3

now product of zeros (alpha *beta) = c/a

so, it will we -2/3

hope you get it !

Make r the subject of the formula: V=πr²h
drek231 [11]
This is called a literal equation, or an equation with multiple variables. You solve it the same as you solve any other equation, but the variables stay there the whole time.

If they want "r" to be the subject, then they want you to solve for r. This means that you need to get the variable r by itself on one side of the equation, but still have the equation be equivalent to it original form.

     I'm going to show you, in steps, how to solve this problem:

<span>V=πr²h

Divide both sides by "</span>π²h<span>"
</span>V/π²h=(πr²h)/<span>π²h
</span>
V/(π²h)=r

Your answer is r=V/<span>π²h</span>
