Answer:

y = -3

Step-by-step explanation:

2y + 6 = 0

2y = -6

y = -3

Since it's just y = -3, there is NO SLOPE and it's just one straight line going horizontally.

So just pick the graph where it's a horizontal line that only goes through the y-axises of -3 (i.e (0, -3), (1, -3), and etc)

(3 x 10^6) x (3 x 10^ 5)

OleMash [197]

Answer:

$9*10^{11}$

Step-by-step explanation:

we have

$(3*10^{6})*(3*10^{5})$

we know that

$(a*10^{b})*(a*10^{c})=(a*a)*10^{(b+c)}$ -----> the bases are multiplied and the exponents are added up

in this problem

$(3*10^{6})*(3*10^{5})=(3*3)*10^{(6+5)}$

$=9*10^{11}$

Write an equation in slope-intercept form of the line that passes through (-5, 19) and (5.13).

ruslelena [56]

Answer:

y=-3/5x+16

Step-by-step explanation:

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

m=(13-19)/(5-(-5))

m=-6/(5+5)

m=-6/10

simplify

m=-3/5

y-y1=m(x-x1)

y-19=-3/5(x-(-5))

y-19=-3/5(x+5)

y=-3/5x-15/5+19

y=-3/5x-3+19

y=-3/5x+16

Of the 50 students in an undergraduate statistics class, 60% send email and/or text messages during any given lecture. They have

sasho [114]

Answer:

0.3 or 30%

Step-by-step explanation:

Since no innocent student will ever be caught, the probability that a student sends an email and/or text message during a lecture AND gets caught is given by the product of the probability of a student sending a message (60%) by the probability of the professor catching them (50%) :

$P = 0.5*0.6 = 0.3$

The probability is 0.3 or 30%.
