------------
L + W = 10 --> W = 10 - L
---
L*W >= 20
----
Solve L*W = 20
L*(10 - L) = 20
-L^2 + 10L - 20 = 0
Given the first term and the common ratio of a geometric
sequence find the first five terms and the explicit formula. a1
= 0.8, r= −5
Answer:
nth term = 0.8 * -5^(n - 1)
First five terms are: 0.8, -4,
20, -100, 500
Step-by-step explanation:
First term, a1 = 0.8
Common ratio, r = -5
a1 = 0.8
Second term = ar
= 0.8 * -5
= -4
Third term = ar²
= 0.8 * -5²
= 0.8 * 25
= 20
Fourth term = ar³
= 0.8 * -5³
= 0.8 * -125
= -100
Fifth term = ar⁴
= 0.8 * -5⁴
= 0.8 * 625
= 500
First five terms are: 0.8, -4,
20, -100, 500
nth term = ar^(n - 1)
= 0.8 * -5^(n - 1)
nth term = 0.8 * -5^(n - 1)
find the difference between (14-3x) and (-9x+7)
Answer:
Step-by-step explanation:
The difference between 14 - 3x and - 9x + 7 is
= 14 - 3x - ( - 9x + 7)
= 14 - 3x + 9x - 7
= 6x + 7

-4w - 3( -9 + 5w) Combine Like Terms Using the Distributive Property

Step-by-step explanation:Hope this help :D
can you help me with this please
Answer:
a) y = 2 x - 1
b) y = - x + 7
c) y = 7 x + 2
Step-by-step explanation:
Use a pair of (x1, y1) and (x2, y2) points to find the equation of the line for each tables:
a) (5, 9) and (10, 19)
slope: (y2 - y1) / (x2 - x1) = (19 - 9) / (10 - 5) = 10 / 5 = 2
Then y = 2 x + b
solve for b in: 9 = 2 (5) + b
b = 9 - 10 = -1
Then y = 2 x - 1
b) (2, 5) and (5, 2)
slope: (y2 - y1) / (x2 - x1) = (2 - 5) / (5 - 2) = -3 / 3 = -1
Then y = - x + b
solve for b in: 5 = - (2) + b
b = 5 + 2 = 7
Then y = - x + 7
c) (3, 23) and (6, 44)
slope: (y2 - y1) / (x2 - x1) = (44 - 23) / (6 - 3) = 21 / 3 = 7
Then y = 7 x + b
solve for b in: 23 = 7 (3) + b
b = 23 - 21 = 2
Then y = 7 x + 2

p=3
then youre done!!! hope this helps have a good day :)
What are the solutions to the equation y^2-1 = 80?
Answer:
y^2-1=80
y^2=81
y = positive and negative 9
y2−1=80
Step 1: Add 1 to both sides.
y2−1+1=80+1
y2=81
Step 2: Take square root.
y=±√81
y=9 or y=−9
Answer:
y=9 or y=−9
Without solving what can you tell about the solution
Answer:

what is the area of a rectangle whose length is (2x-1) cm and whose width is (X+2) cm?
help.
Answer:
2x^2 + 3x - 2
Step-by-step explanation:
=> area of rectangle = length*width
=> length = (2x -1)
=> width = (x + 2)
=> area = (2x - 1) (x + 2)
=> area= 2x(x + 2) - 1(x + 2)
=> area = 2x^2 + 4x - 1x - 2
=> area = 2x^2 + 3x - 2
hope it helps
Please help I need to get this done and I have no idea what I'm doing!
Answer:
5
Step-by-step explanation:
(125) ^ (1/3)
We can rewrite 125 as 5^3
( 5^3) ^ 1/3
We know that a^b^c =a ^ (b*c)
5 ^(3*1/3)
5^ 1
5
Answer:
5
Step-by-step explanation:
when something is to the power of 1/2, that means you square root it
when it is to the power of a third, that means you cube root it.
for example, if it is 25 to the power of a half, that means [tex]\sqrt{25} = 5[/tex] because
5 x 5 = 25
this is the same concept
we need to find a number that multiplies itself 3 times and equals to 125
5x5x5 = 125, meaning that
125 to the power of a third, is 5.
