Step-by-step explanation:
Answer:
y = 4x - 1
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 )
rearrange 4x - y = 1 into this form
add y to both sides
4x = y + 1 ( subtract 1 from both sides )
4x - 1 = y
y = 4x - 1 ← in slope-intercept form
Answer:
The answer is B.
Step-by-step explanation:
The pattern seems to be counting by two.
Answer:
y = 14
Step-by-step explanation:
Since AC = BC then the triangle is isosceles and the base angles are congruent, that is
∠A = ∠B = 50°, thus
∠C = 180 - (50 + 50) ← sum of angles in Δ = 180°
= 180 - 100 = 80°, hence
5y + 10 = 80 ( subtract 10 from both sides )
5y = 70 ( divide both sides by 5 )
y = 14
