0.25t = 3 is the equation or 0.25t = h but the first one would be used to solve it i think
Answer:
Exact form: x=19/9
decimal form: x=2.1r
Mixed number form: x=2 1/9
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
A pentagon, 5 sides, all internal angles add up to 720°, so wen u do the maths, X=5

Answer: y = (9/4)x - 2</h3>
=======================================================
Explanation:
Line K is 9x-4y=-5*4 which is the same as 9x-4y=-20
Rule: Anything parallel to Ax+By = C is of the form Ax+By = D.
The equation 9x-4y=-20 has A = 9, B = -4 and C = -20.
That means Ax+By = D becomes 9x-4y = D.
------------------------------
Plug in the coordinates (x,y) = (4,7) and compute the value of D.
9x-4y = D
D = 9x-4y
D = 9(4)-4(7)
D = 36 - 28
D = 8
So 9x-4y = D becomes 9x-4y = 8
----------------------------
The last step is to solve for y to get the equation in y = mx+b form.
9x-4y = 8
-4y = 8-9x
-4y = -9x+8
y = (-9x+8)/(-4)
y = (-9x)/(-4) + 8/(-4)
y = (9/4)x - 2 is the slope-intercept form of line L
The equation is in y = mx+b form where,
m = 9/4 = slope
b = -2 = y intercept
