Answer:

Step-by-step explanation:

The slope intercept form of a line is y=mx+b where m is the slope and b is the y intercept. We are given a slope of three so

y=3x+b, using point (1,3) we can solve for b

3=3(1)+b, 3-3=0 so b=0 then our line is

y=3x

The x intercept is when y=0 and this occurs when x=0 or the point (0,0)

The y intercept occurs when x=0, this occurs when y=0 or the point (0,0)

Which equation is not equivalent to the formula d = rt? A. r= t over d B. r= d over t C. t=d over r D. d=tr

taurus [48]

D = rt

d/r = t
d/t = r
d = tr

incorrect one is : r = t/d

Given that the population density of Georgia is 170 people per square mile and 10,100,000 people live in Georgia, what is the ar

WINSTONCH [101]

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Number of people living in Georgia = 10,100,000

Number of people living in per square mile = 170

So, we need to find the area of the state :

So, Area of the state is given by

$\frac{\text{Total Population}}{\text{ Number of people per square mile }}\\\\=\frac{10100000}{170}\\\\=59411.76\\\\=59400(\text{ nearest hundred }mi^2)$

Hence, Option 'D' is correct.

Pls help me in these two little exercises about the slope.

den301095 [7]

Answer:

3) $y=\dfrac35x+\dfrac25$

4) a) $y=-2x+7$

b) $y=\dfrac12x+\dfrac92$

Step-by-step explanation:

<u>Exercise 3</u>

$-3x + 5y = 2$

$\implies 5y = 3x + 2$

$\implies y=\dfrac35x+\dfrac25$

<u>Exercise 4</u>

a) If L2 is parallel to L1, it has the same slope (gradient) ⇒ $m = -2$

If L2 passes through point (3, 1):

$y-y_1=m(x-x_1)$

$\implies y-1=-2(x-3)$

$\implies y=-2x+7$

So L2 = L1

b) If L3 is perpendicular to L1, then the slope of L3 is the negative reciprocals of the slope of L1 ⇒ $m = \dfrac12$

If L3 passes through point (-5, 2):

$y-y_1=m(x-x_1)$

$\implies y-2=\dfrac12(x+5)$

$\implies y=\dfrac12x+\dfrac92$

Can i get help working out 3x− 12 = 2x+ 3

Naddik [55]

Answer:

x = 15

Step-by-step explanation:

3x− 12 = 2x+ 3

3x-2x-12 = 3

x = 3+12

x=15

hope this helps! :)
