Option B. $900
Step-by-step explanation:
Let
y ----> the value of the car
x ----> the time in years
we know that
The linear function in slope intercept form is equal to
where
m is the slope or the depreciation rate
b is the y-intercept or initial value of the car
we have
The y-intercept or initial value is equal to
we have the ordered pair (5,500)
substitute the value of x and the value of y of the ordered pair in the linear equation and solve for m
Is negative because is a decreasing function
The linear equation is equal to
therefore
It would depreciate $900 each year.

Answer: there are 59059 lbs of gravel.
Step-by-step explanation:
In a mixture of concrete, there are four lbs of cement mix for each pound of gravel. This means that eight lbs of cement would be mixed for 2 pounds of gravel and 12 lbs of cement would be mixed for 3 pounds of gravel and 12. Therefore, the constant ratio of cement to gravel is 4:1
The total ratio is 4 + 1 = 5
If the mixture contains a total of 295295 lb of these two ingredients, then the number of pounds of gravel that are there is
1/5 × 295295 = 59059 lbs
Answer:
dilation
Step-by-step explanation:
whenever the shape is dilated, or scaled by a factor of any number, the shape will change size and will become similar rather than congruent. congruent shapes have the same dimensions as the parent or original shape.
