Point slope form
y-y1=m(x-x1)
where the point is (x1,y1) and the slope is m

the slope between the points (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given
(2,5) and (3,0)
slopoe=(0-5)/(3-2)=-5/1=-5
m=-5

we see we are given
y-__=__(x-2)
x1=2
the point used was (2,5)
therefor
y1=5
m=-5

y-5=-5(x-2)

Y- (5+0)= 2+3(x-2)
Y-5=6(x-2)
y-5=6x-2
+5 +5
y=6x+7
6x+7=x-2
-x -7 -x -7
5x=9
9/5
the answer is 1.8

IN THE LAST TWO WEEKS , A PLANT GREW 1/16 IN. AND 3/16 IN. RESPECTIVELY

grandymaker [24]

I'm assuming you mean that the plant grew 1/16th of an inch the first week, and 3/16th of an inch the next week. Simply add the two together (4/16th) and simplify. Since four goes into both numbers, the simplified version is 1/4th. Hope this helps

Suppose you have a coin collection of dimes and quarters containing 46 coins. If you have 6.70 dollars, how many of each type of

NNADVOKAT [17]

Answer:

The number of dimes = 32

The number of quarters = 14

Step-by-step explanation:

Here, the total number of coins combined = 46

Let us assume the number of dimes = m

So, the Number of quarter = Total Coins - Number of dimes = 46 - m

Now,as we know:

1 dime = $0.1

So, m dimes = m x ($0.1) = $(0.1 m)

1 Quarter = $0.25

So, ( 46 - m ) Quarters = (46 - m ) x ( $ 0.25) = 11.5 - 0.25 m

Also, given the total amount of coins = $ 6.70

⇒ Value of (Dimes + Quarters) = $ 6.70

or, (0.1 m) + 11.5 - 0.25 m = 6.70

-0.15 m = - 4.8

or, m = 4.8/0.15 = 32

⇒ m = 32

Hence, the number of dimes = m = 32

And the number of quarters = 46 - m= 46 -32 = 14
