Answer:
32
Step-by-step explanation:
We are given the expression:
and asked to evaluate the expression.
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Solve inside the parentheses first. Subtract 37 from 13.
⇒ 13-37= -24
Next, multiply -8 and -24.
⇒ -8*-24= 192
Finally. divide 192 by 6.
⇒ 192/6 = 32
When evaluated, the expression -8(13-37)/6 is equal to 32.
Answer:
(-2.2, -1.6), (3, 1)
Step-by-step explanation:
You don't have to go far to find the equations. They are right there in your problem statement. Perhaps you want to find the solutions to the equations.
Use the first equation to write an expression for x, then substitute that into the second equation:
x = 2y +1
y^2 -3(2y+1)(y) +8 = 0
-5y^2 -3y +8 = 0
-(5y +8)(y -1) = 0
y = -8/5 or y = 1
The corresponding values of x are ...
x = 2(-8/5)+1 = -11/5
x = 2(1) +1 = 3
The solutions are (x, y) = (-2.2, -1.6) and (3, 1).
