1. Given point (-3, -5) and a slope of 2, write an equation in point-slope form.

andrew11 [14]

Answer:

option c in both cases

Step-by-step explanation:

The equation of a line in point- slope form is

y - y₁ = m(x - x₁ )

where m is the slope and (x₁, y₁ ) a point on the line

(1)

Here m = 2 and (x₁, y₁ ) = (- 3, - 5) , then

y - (- 5) = 2(x - (- 3) ) , that is

y + 5 = 2(x + 3)

(2)

Here m = 4 and (x₁, y₁ ) = (- 6, - 3) , then

y - (- 3) = 4(x - (- 6) ) , that is

y + 3 = 4(x + 6)

After a 15% increase, a town has 115 people. What was the population before the increase?

Arte-miy333 [17]

Answer:

100 people

Step-by-step explanation:

Population Of People=115Percentagencrease=15%

The New Population corresponds to 115%

(That is 100+15)

We want to find the population that corresponds to 100% that is the original population.

Therefore Original Population;

 $\frac{100}{115}\times {115}{}$ 

 $100 \: people$

Hello there!

Usimov [2.4K]

firstly chain rule is dy/dx = dy/du * du/dx

a) y = 5u² + u - 1 hence dy/du = 10u +1

u = 3x +1 hence du/dx = 3

so dy/dx = 3(10u +1) {sub in u and expand}

b) y= u^-2 hence dy/du = -2u^-3

u=2x+3 hence du/dx = 2

so dy/dx= 2(-2u^-3) {sub in u}
