Answer:

(y+2)=3/4(x+6) or (y-4)=3/4(x-2)

Step-by-step explanation:

Point-slope form : (y-y1)=m(x-x1)

slope = m =(y2 - y1)/(x2 -x1)

Point 1 (-6,-2), so x1= - 6, y1= -2

Point 2 (2, 4), so x2 = 2, y2 = 4

m=(4-(-2))/(2-(-6)) = 6/8 = 3/4

Point-slope form : (y-y1)=3/4(x-x1)

We can use any point. If we use point 1 we get

Point-slope form : (y+2)=3/4(x+6).

If we use point 2 we get

(y-4)=3/4(x-2)

Mango farm contains 1250 mango trees. Each tree produces an average of 160 Mango’s during the summer how many such mango forms a

serious [3.7K]

If a farm contains 1250 trees, and each tree produces 160 mangoes, the farm produces

$1250 \times 160 = 200000$

This means that $k$ farms produce $200000k$ mangoes.

If you want 1 million mangoes, you must solve the equation

$200000k = 1000000 \implies k = \cfrac{1000000}{200000} = 5$

So, you need 5 farms.

(19x^2+12x+12)+(7x^2+10x+13)

MatroZZZ [7]

Answer:

$26x^2+22x+25$

Step-by-step explanation:

We remove the brackets, getting $19x^2+12x+12+7x^2+10x+13$ .

We then combine like terms, getting $(19+7)x^2+(12+10)x+(12+13)$ .

As a result, we get $26x^2+22x+25$ .
