Answer:
the b is 20
Step-by-step explanation:
The computation of the b is shown below
Given that
y = mx + b
where
m = -2
x = 3
y = 14
Now placing these values to the above formula to determine the value of b
14 = -2(3) + b
14 = -6 + b
b = 14 + 6
= 20
Hence, the b is 20
We simply applied the above formula so that the correct value could come
And, the same is to be considered
Answer:
all real numbers.
Step-by-step explanation:
9x - 8y = 1
18x - 16y = 2
if you look at the first equation, you can figure out what y equals.
9x - 8y = 1
<em>add 8y to both sides</em>
9x = 1 + 8y
<em>subtract 1 from both sides</em>
9x - 1 = 8y
<em>divide both sides by 8</em>
= y
<em />
now, substitute y in the second equation.
18x - 16y = 2
18x - 16() = 2
18x - 2(9x - 1) = 2
18x - 18x +2 = 2
2 = 2
the answer is <em>all real numbers, </em>because regardless of what x equals, 2 will always equal 2.
