Answer:
A. y=1-2x
Step-by-step explanation:
if to substitute the values of 'x'=1; 2; 3; 4 into the equations, only the 'A' is correct.
Answer:
PR = 24.5
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
, that is
=
( cross- multiply )
18PR = 28 × 15.75 = 441 ( divide both sides by 18 )
PR = 24. 5
The simplified version of that would be 4x^3 + 10x +3.
Sorry if this was wrong but hope it’s right!
You cant use the division of rational numbers to describe data
Answer:
2880 m
Step-by-step explanation:
find the area under the graph. i have split it into 3 areas A, B and C
A (trapezium) = 1/2 x (150 + 160) x 15 = 2325
B (trapezium) = 1/2 x (15 + 6 ) x (160 - 110) = 525
C (triangle) = 1/2 x 10 x 6 = 30
total = 2325 + 525 + 30 = 2880
