Answer:
A
Step-by-step explanation:
Being similar means that the shapes will have the same shape and dilation factor between sides, but if they are not congruent then the size will not be the same.
Given
One month julia collected 8.4 gallons of rainwater.
she used 5.2 gallons of rainwater to water her garden
6.5 gallons of rainwater to water flowers
Find out how much was the supply of rainwater increased or decreased by the end of the month.
To proof
As given in the question
One month julia collected 8.4 gallons of rainwater
she used 5.2 gallons of rainwater to water her garden and 6.5 gallons of rainwater to water flowers
Total water she used in the month = 5.2 gallons + 6.5gallons
= 11.7 gallons
Let the supply of rainwater increased or decreased by the end of the month
be x .
Than the equation become in the form
x + 8.4 = 11.7
x = 3.3 gallons
Therefore the supply of rainwater increased or decreased by the end of the month is 3.3 gallons.
Hence proved
The equation would be 2x + 5y = 11.
To find this, we first have to find the slope of the line. The slope formula is below.
m (slope) = (y2 - y1)/(x2 - x1)
In which (x1, y1) is the first point and (x2, y2) is the second. So we plug in to solve.
m = (3 - 1)/(-2 -3)
m = 2/-5
Now that we have the slope, we can use it along with a point to get the slope intercept form.
y = mx + b
3 = -2/5(-2) + b
3 = 4/5 + b
11/5 = b
Now that we have the equation of y = -2/5x + 11/5 we can manipulate it into standard form.
y = -2/5x + 11/5 -----> add 2/5x to both sides
2/5x + y = 11/5 ----> multiply both sides by 5
2x + 5y = 11
