Answer:

5/7 and -7/5

Step-by-step explanation:

slope is - 7/5

if line is written as Ax + By + C = 0

the slope is -A/B

if you work that equation you have

By = - Ax - C

y = (-A/B) × x - C/B

and term multiplying the x is the slope in case you had doubts about the - A/B

the multiplication of the slopes of 2 lines that are perpendicular is - 1

x × -7/5 = -1

x = 5/7

the slope of 2 lines that are parallels is the same, so slope = -7/5

The population of a town in 2000 was 430. The population is increasing at a rate of 0.9% every year. What will be the projected

Virty [35]

Answer: a 470

Step-by-step explanation:

The exponential growth equation with rate of growth r in time period t is given by :-

$y=A(1+r)^t$ , where A is the initial amount

Given : The rate of growth of population every year : 0.9% =0.009

The initial population = 430

Then , the exponential growth equation in time period t is given by :-

$y=430(1+0.009)^t$

In 2010 or for t= 10 years

The projected population of the town will be :-

$y=430(1.009)^{10}=470.305565305\approx470$

Hence, the projected population of the town in 2010 is about 470.

7x + 2 = 5(x − 2)<br><br> Find X

d1i1m1o1n [39]

Answer:

-6

Step-by-step explanation:

$7x + 2 = 5(x - 2) \\ 7x + 2 = 5x - 10 \\ 7x - 5x = - 10 - 2 \\ 2x = - 12 \\ x = \frac{ - 12}{2} \\ x = - 6$

Trinity solved the equation 2(x-3)+7-3x=11.

lukranit [14]

Answer:

$x=-10$

Step-by-step explanation:

$2(x-3)+7-3x=11$

$2\left(x-3\right)+7-3x-7=11-7$

$2\left(x-3\right)-3x=4$

$-x-6=4$

$-x-6+6=4+6$

$-x=10$

$\cfrac{-x}{-1}=\cfrac{10}{-1}$

$x=-10$

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided.

BabaBlast [244]

Answer: 8

Step-by-step explanation:

Pythagorean theorem - a^2+b^2=c^2

a^2+15^2=17^2

a^2+225=289

(subtract 225 from both sides)

a^2=64

(sq root both sides)

a=8
