Answer:
Step-by-step explanation:
What variable are you solving for?
-4x+y=29
y=29-(-4x)
y=29+4x
y=4x+29
----------------
-4x=29-y
-4x=-y+29
x=1/4y+29/-4
y=1/4y-29/4
Answer:
x = 6
Step-by-step explanation:
Given
6x² - 2x + 36 = 5x² + 10x ( subtract 5x² + 10x from both sides )
x² - 12x + 36 = 0 ← in standard form
This is a perfect square of the form
(x - a)² = x² - 2ax + a²
36 = 6² ⇒ a = 6 and 2ax = (2 × 6)x = 12x, hence
(x - 6)² = 0
x - 6 = 0 ⇒ x = 6
Answer:
The first one sounds suprising but what is the action?
Answer:
perimeter of rectangle = 2(l+b)

Answer:
C
Step-by-step explanation:
All real numbers means all numbers positive and negative
Therefore, it would have to be C because the others dont have both positives and negatives for their domain and range reaches
