The prices of two radios are in the ratio x : y when the prices are both increased by £20 , the ratio becomes 5 : 2 when the prices are bith reduced by £5 , the ratio becomes 5:1 express the ratio x : y in its lowest terms

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

f(x)=2/3x-8, which give g(x) the greatest value.
