70 * 0.22 = 15.4
70 + 15.4 = $85.40
The total cost is $85.40
Answer:
domain -4≤x≤4
range -1≤y≤2
Step-by-step explanation:
Answer:
U= 60
Step-by-step explanation:
it is 60 because they are opposite but they = each other. also if u want proof (the long way) then u do subtract the degree of the line which is 180. so 180-60 = 120 for the first line. so the angle next to the 60 is 120, now u do 180-120=60 and thats = to u
Answer:
The gradient of a line is given by
.
Any 2 points of a vertical line would have the same x-coordinate. Thus when you simplify the denominator, you would end up with a zero. If you enter that into your calculator, no matter what you numerator is, you would get a Math error. This is because you cannot possibly divide a number by zero. Thus, the gradient is undefined.
