x=-7
Answer:
In three years can be into algebraic terms as: 3 + x. Where 'x' comes to be today's age.
For example, my age in three years will be:
If I'm 24 years right now, My age in three years = 3 + x ⇒ My age in three years = 3 + 24 = 27.
Answer:
Step-by-step explanation:
x-intercept: Set y = 0 and solve for x:
0 = mx + b, or mx = -b, or x = -b/m. x-intercept is then (-b/m, 0)
y-intercept: Set x = 0 and solve for y: y = m(0) + b, or y = b. y-intercept is then
(0, b).
