Answer: she bought 13 petunias
Step-by-step explanation:
Let x represent the number of Petunias pot of flowers that she bought.
Let y represent the number of begonias pot of flowers that she bought.
She bought 22 potted plants. This means that
x + y = 22
Petunias cost $7 per pot and begonias cost $8 per pot. She spent a total of $163. This means that
7x + 8y = 163 - - - - - - - - - - - -1
Substituting x = 22 - y into equation 1, it becomes
7(22 - y) + 8y = 163
154 - 7y + 8y = 163
- 7y + 8y = 163 - 154
y = 9
x = 22 - y = 22 - 9
x = 13
The answer is 589,918
Take 652203 and subtract 62,285 from that and you get 589,918
Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
To calculate m use the slope formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 6) and (x₂, y₂ ) = (8, 4)
m =
= -
, hence
y = -
x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, 4), then
4 = -
+ c ⇒ c = 4 +
= 
y = -
x +
← equation of line
