Answer:
P (−11, 13), Q (−17, −19), R (23, 27)
Step-by-step explanation:
we know that
The reflection of a figure across the x-axis has the following rule
(x,y) -----> (x,-y)
so
P(-11,-13) -----> P(-11,13)
Q(-17,19) -----> Q(-17,-19)
R(23,-27) ----> R(23,27)
S=saving
X=amount left
S-55=x
Another way : x=s-55
Answer:
51 mg
Step-by-step explanation:
A new health drink has 170% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 30mg.
The above question is calculated as:
RDA of the vitamin × 170%
The RDA for this vitamin is 30mg
Hence:
30mg × 170%
= 51 mg
Therefore, the milligrams of the vitamin that are in the drink is 51 mg
X + yi + 2x + 2yi + 3i = 9 this first step is just distributing the 2
3x + 3yi = -3i + 9 this step is adding like terms
x+ yi = 3 - i this step is dividing by 3 to all terms... Lowest common factor
then subtracting 3i to the right side of the equation
so x =3 and y= -1
if that the full question?
