Answer:
y =1/2
Step-by-step explanation:
solve for ; y
10(1 – 2y) = -5(2Y - 1)
-10(2y-1) +5(2Y - 1) =0
(2y-1)(-10+5) = 0
-5(2y-1) =0
2y-1=0
y = 1/2
Answer:
142°
Step-by-step explanation:
Hope this can help you out some! :)
*There is a line under the greater than and less than sign is to show it can "greater than or equal to" or "less than or equal to"*
9 ≥ w and 2 ≤ w
*Since it says and, we solve both of them together.
If it said "OR", we would do the one side first then the other side*
9 ≥ w and 2 ≤ w
-2 -2
7 ≥ w and 0 ≤ w
Answer:
7 ≥ w and 0 ≤ w

Answer:
CT= $950
Step-by-step explanation:
Dado la siguiente información:
Servicio= $300 primeros dos
Servicio adicional= $150
Descuento= $100
<u>Para calculate el costo total, tenemos que usar la siguiente formula:</u>
CT= 300x + 150y - 100
x= costo normal
y= costo promocional
CT= 300*2 + 150*3 - 100
CT= $950
4.3 Solving 3x2-2x-1 = 0 by the Quadratic Formula .
According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :
- B ± √ B2-4AC
x = ————————
2A
In our case, A = 3
B = -2
C = -1
Accordingly, B2 - 4AC =
4 - (-12) =
16
Applying the quadratic formula :
2 ± √ 16
x = —————
6
Two real solutions:
x =(2+√16)/6
or:
x =(2-√16)/6
