Answer:
n = 8
Step-by-step explanation:
512/-4 = -128
-2^? equals -128? Has to be odd since it's negative
-2^1 = -2
-2^3 = -8
-2^5 = -32
<u>-2^7 = -128</u>
But it's -2^n-1 = -128 so you have to add 1
7+1 = 8
So n=8
4(7x−3)−6=6−4(3x−7)
Distributive property
28x - 12 - 6 = 6 - 12x + 28
28x - 18 = -12x + 34
28x + 12x = 34 + 18
40x = 52
x = 52/40
x = 13/10
or
x = 1 3/10 (mixed number: 1 and 3/10)
All marbles together are 24 marbles. 14 of those are yellow marbles. 24 subtract 14 is 10. the probability of the marble not being yellow is 10/24
Answer:
$y=(7/2)x+20$
Step-by-step explanation:
SInce the gradient of the first line is $-2/7$ then the gradien of the perpendicular line is $7/2$.
Therefore by the point slope formula the line that we are looking for is
$y-6=(7/2)(x+4)$
$y=(7/2)x + 20$
