<h2>
Answer: c.) ¹⁵/₄</h2>
Step-by-step explanation:
If we transpose the equation into the slope-intercept form (y = mx + c), the value of c is the y-intercept.
since x + 4y = 15
then 4y = - x + 15
∴ y = -¹/₄ x + ¹⁵/₄
<h3>⇒ the y-intercept for the line x + 4y = 15 is ¹⁵/₄</h3>
Answer:
x = 3 or x = -1/4
Step-by-step explanation:
from (x-3)(4x+1) = 0
We can see that a * b = 0
so a = 0 or b = 0
thus
x - 3 = 0 or 4x + 1 = 0
we solve x = 3 or x = -1/4
