Answer:
y = x + 30
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 30) and (x₂, y₂ ) = (70, 40) ← 2 points on the line
m = = =
The line crosses the y- axis at (0, 30) ⇒ c = 30
y = x + 30 ← equation of line
D. Infinitely many because the lines will never Intersect which means there are infinitely solutions
Answer:
Option C
Step-by-step explanation:
we have
Remember that
therefore
Answer:
11
Step-by-step explanation:
z = 2; therefore, f(z) = f(2).
The letter/number inside of the bracket replaces the orginal letter, in this case w.
f(w) = 2w^3 - 5
f(2) = 2(2)^3 - 5
f(2) = 2(8) - 5
f(2) = 16 - 5
f(2) = 11
As a result, f(z) = 11
V*t=S
V=3x10^8 m/s
S=7.5x10^6 m
t=S/V = 7.5x10^6 / 3x10^8 = 7500 000 / 300 000 000 = 0.025 s
