Bradley is returning home from a place that is 2 kilometers away the function y=2,000-90x represents Bradley’s distance from hom e in meters,y, in relation to the number of minutes he walks x Which statements about this function are true ?
A the function is a liner function
B the function is a nonlinear function
C the function does not change at a constant rate
D the function is an increasing function
E the function changes at a constant rate
1 answer:
These are the statements that accompany this question: A.The function is a linear function. B.The function is a nonlinear function. C.The function does not change at a constant rate. D.The function is an increasing function. E.The function changes at a constant rate. An this is the assesment of each of statement: A.The function is a linear function. TRUE: a linear function can take the forms Ax + By - C = 0, or y = mb + b You can verify that y = 2000 - 90 x is of this type. B.The function is a nonlinear function. FALSE: we showed the opposite in A) C.The function does not change at a constant rate. FALSE: the rate of change of a linear function is constant and it is known as the slope. D.The function is an increasing function. FALSE: the value of y decreases as x increases, given that the slope is negative ( -90).E.The function changes at a constant rate. TRUE: the constant rate is the slope, i.e. - 90.

Answer:
You have to solve for the letter
Step-by-step explanation:
For example, Q5 is 40 - 5n = -2.
You subtract 40 from -2 and get -42 then you have 5n = -42. You divide 5 to -42 so . The answer is -8.4. *Use a calculator if necessary.*

Answer:
175/3 π
The volume of a cone is 1/3 of a cylinder with the same measurements.
If the cylinder is 175π then the cone is 175/3 π.-
Answer:
$162.50
Step-by-step explanation:
I=Prt
I=(5000)(0.065)(0.5)
I=162.50
0.5 = 6 months, which is half of a year
0.065 = the percent (6.5%) in decimal form
