- 22 because it is less than 28
Answer:
the last one
Step-by-step explanation:
plug in -2 for x and -3 for y
Answer:
If the question is 
then the answer is no real solution. If the question is 2x - 18x + 65 than the answer is -16x+65
Answer:
y = 0.265x - 494.7
Step-by-step explanation:
Let median age be represent by 'a' and time be represent by 't'
In 1980, median age is given 30
which means that
a₁ = 30
t₁ = 1980
In 2000, the median age is given 35.3
which means that.
a₂ = 35.3
t₂ = 2000
The slope 'm' of the linear equation can be found by:
m = (a₂ - a₁) /(t₂ - t₁)
m = (35.3 - 30)/(2000-1980)
m = 0.265
General form of linear equation is given by:
y = mx + c
y = 0.265x +c
Substitute point (1980,30) in the equation.
30 = 0.265(1980) + c
c = -494.7
Hence the the linear equation can be written as:
y = mx + c
y = 0.265x - 494.7
3x-16x-24=-12x-30
-13x+12x=-30+24
-x=-6 /*(-1)
x=6
