Answer:
r = 13
Step-by-step explanation:
these angles are vertical and are congruent
8r + 6 = 9r - 7
6 = r - 7
13 = r
Answer:
x = 3
Step-by-step explanation:
Given
4 : 8 = x : 6, expressing in ratio form, that is
=
( cross- multiply )
8x = 24 ( divide both sides by 8 )
x = 3
Thus 4 : 8 = 3 : 6
(a)36 = 6
(b)81 = 9
(c)256 = 16
(d)196 = 14
Answer:
D
Step-by-step explanation:
firstly,y-intercept, x=0,A and b wrong
sub x=0
0.25⁰=1
(0,1)
