X = 4
First take 12x off both sides, so -7x=-28
The negatives cancel out, so 7x=28
Not find the hcf and divide by that.
Answer:
variable
Step-by-step explanation:
A variable is a American, Latin, Greek etc letter used to represent an unknown.
Answer:
α ≈ 76°
Step-by-step explanation:
The vertices of a rectangle are right , that is 90°
Using the tangent ratio in right triangle ABC
tanα = 
= 
= 
= 4, then
α = 
(4) ≈ 76° ( to the nearest degree )
The answer for ur question is C..

Using the slope intercept formula, the equation for the line in slope intercept form is y = -x - 4
<h3>Slope intercept equation</h3>
The slope intercept equation can be describe as follows:
y = mx + b
where
Therefore,
(-4, 0)(1, -5)
m = -5 - 0 / 1 + 4 = -5 / 5 = -1
Therefore, let's find b using (1, -5)
-5 = -1(1) + b
-5 = -1 + b
b = -5 + 1
b = -4
Therefore, the equation is y = -x - 4
