Function a and function b are linear functions. function a isrepresented by the table of values function b is represented by the equation.
function a table:
x. y
1. 2
3. 10
4. 14
7. 26
function b: y=3x+4

which statements about the properties of function a and b are true (there are 2)
a) the y intercept of a function equalto the y intercept of the function b
b) the y intercept of a function a is less than the y intercept of function b
c) the y intercept of a function a is greater than the y intercept of a function b
d) the rate of change of function a is equal to the rate of change of a function b
e) the rate of change of function a is less than the rate of change of function b
f)the rate of change of a function a is greater than the rate of change of function b

boxplot e is the answer

what is the original number? you forgot to add it.

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
