Step-by-step explanation:
replace the value of x with 1
y + 0.5 × 1 × y = 1 + 2
do the maths
y + 0.5y = 3
here the value of y is equal to 1. same goes for x, if we have no given value for them.
1.5y = 3
y = 3/1.5
y = 2
Answer:
Hundreths 3 is in the hundreths
Step-by-step explanation:
The domain of a relation is all the x - values the relation can take, so:
domain = {-8, -6, 5}
The range, in addition, is all the y - values the relation can take, so:
range = {-3, -1, 0, 5}
Answer:
22
Step-by-step explanation:
4(2)² + 4(2) - 2
Use PEMDAS, which is Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction. In that order we evaluate.
Exponents first, since there is nothing else to do in the parenthesis.
4(2)² + 4(2) - 2
4(4) + 4(2) - 2
Next is Multiplication and Division
4(4) + 4(2) - 2
16 + 8 - 2
Lastly are Addition and Subtraction
16 + 8 - 2
16 + 6
