X - y = -3
y = x + 3.......slope = 1, y intercept = (0,3)
to find x int, sub in 0 for y and solve for x
x - y = -3
x - 0 = -3
x = -3....so the x intercept = (-3,0)
plot ur points (0,3) and (-3,0)......now start at (-3,0)....and since ur slope is 1, go up one, and to the right 1, and up 1, and to the right 1.....do this over as many times as needed and u should cross the y axis at (0,3)
Answer:
x = 6 cm
Step-by-step explanation:
Given ratio of sides of similar figures = a : b , then
ratio of areas = a² : b²
Here ratio of areas = 5 : 45 = 1 : 9 , so
ratio of sides =
:
= 1 : 3
Thus side of B is 3 times side of A
x = 3 × 2 = 6 cm

Answer:
b. the association is consistent when results are repeated in studies in different settings using different methods
Step-by-step explanation:
-In statistics and research, internal consistency is typically a measure based on the correlations between different items on the same test (or the same subscale on a larger test).
-It measures whether several items that propose to measure the same general construct produce similar scores.
