First equation simplifies to
y=(4/5)x-1
The second equation simplifies to
y=(4/5)x +1
So the answer is
No Solution
Answer:
-13
Step-by-step explanation:
3x^3 - 2y^-6x^2y^2+xy
x=2/3 and y=1/2
Solve :
3x^3 - 2y^-6x^2y^2+xy
Put value of x and y in this equation
= 3(2/3)^3 - 2(1/2)^-6(2/3)^2(1/2)^2+(2/3)(1/2)
= -13
Frank worked 25 hours as a waiter last week.
<h2>Simultaneous equation</h2>
- Let the time spent as a waiter be x
- Leet the total time spent as a busser be y
If<u> Frank worked both jobs f</u>or a total of 36 hours, hence:
x + y = 36
x = 36 - y
Also, if he earns $12 per hour as a waiter and $10 per hour as a busser and earned a total of $410, then;
12x + 10y = 410
Substitute 1 into 2
12x + 10y = 410
12(36 - y)+ 10y = 410
432 -12y + 10y = 410
-2y = -22
y = 11
Since x = 36 - y
x = 36 - 11
x = 25
Hence frank worked 25 hours as a waiter last week.

Answer:
C.
Step-by-step explanation:
Multiplying identical variables together is identical to adding the exponents of each.
In this case, you have three 
s. You can multiply these to create 
.
Now, you have 
.
Negative exponents mean that the base (b in this scenario) is on the opposite side of the fraction line.
