Well, If you want 4 letter codes with 5 letters, would be 5 x 4 x 3 x 2 which is 430. (It gets less because If you use one letter you cant use it again.)

Lina20 [59]

Answer:

y=-4x-14

Step-by-step explanation:

Lines that are parallel would have the same slope, so the slope is

m= -4

Use point slope equation to solve for the slope intercept equation.

y-y1=m(x-x1)

m= -4

x= -3

y= -2

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

y+2=-4x-12

y=-4x-14

Divide. 0.0075 ÷ (1.5  x  10−6) write your answer in scientific notation.
Alborosie
0.0075 ÷ (1.5 x 10^-6) = (7.5 x 10^-3) ÷ (1.5 x 10^-6) = (7.5 ÷ 1.5) x (10^(-3 - (-6))) = 5 x 10^(-3 + 6) = 5 x 10^3

Can someone Please answer some of these questions Please ASAP Thank you:)) (20 points)
Kryger [21]

Answer:

for #1 it's 1, 4, 5, 6

for #2 it's both lines have the same slope

for #3 it's both lines have a different y-intercept

Step-by-step explanation:

#1 explanation: all of them have the y-intercept of -8

ex. y = 3x (- 8) y = 5x (-8) y = 2x (-8) y = (1/3)x (-8)

#2 explanation: both have a slope of (1/4)

#3 explanation: y = (1/4)x there is not y-intercept that we know of and y = (1/4)x - 5 the y-intercept is at -5 therefore the y-intercepts are different
