Twelve times 3 added to three is equal to?
Answer:
Slope = -4 y-intercept= -8
Step-by-step explanation:
This equation is in slope intercept form, which is always written in the format of y=mx+b. The m means slope and the b means y-intercept, so you can just substitute the variables for the values.
Answer:
Step-by-step explanation:
y=kx
4=k(-2)
k=-2
y=-2x
when x=30
y=-2*30=-60
if a b 9 are in GP
b÷a = 9 ÷ b
b^2 = 9a
if a - 1 b 9 are in AP
2b = a+8
b = a+8÷2
substitute
b is equal to a + 8 by 2 in b square equal to 9 a
(a+8÷2)^2 = 9a
a^2+16a+64 = 36a
a^2 -20a +64 =0
(a-16) (a-4) =0
a= 16 or a=4
when a=16 b= 12
when a=4 b= 6
Value of a and b are given above
Answer:
46mins
EXPLANATION
