Answer:
gradient is the same as slope The gradient or slope of line A = 3/1 or 3
The gradient of line B is -4/1 or -4
gradient or slope = rise over run = y/x.
if the line goes up from the left to the right, The slope is positive.
if the line goes down from the left to the right, The slope is negative
Hello :
y= <span>x² - 4x + 1
calculate : x
y = (x²-4x+4)-4+1
y+3 = (x-2)²
x exist : if y+3 </span><span>≥ 0
y </span><span>≥ -3
the range is : </span><span>{y: y ≥ -3}</span>

Answer:
7
Step-by-step explanation:
The angles that we are sure about is 33 and 90. The angles of a triangle add up to 180. 33 + 90 = 123. 180 - 123 = 57. 57 = 7x+8, 49 = 7x, x = 7.
