Answer:
1200
Step-by-step explanation:
Since the value they are asking for is in minutes, we need to convert seconds to minutes. We can do that by multiplying 4 and 60, because there are 60 seconds in a minute, and we need to find the value of one minute. Also because the value they gave is 4. When we do this, we get 240. To get the final answer, we need to multiply 240 and 5, because 240 is the descending rate per minute, and they are asking for 5 minutes. When we do this, we get 1200.
(I might get this wrong, so like yeah.)
The range is all of the y values.
The domain of all quadratics is all real numbers, but the range of y=x^2 is y≥0. This is because quadratic functions graph to form a parabola, which, when the a value is positive, opens upward. The lowest y value when graphed is 0 and all other values are more than that.
The definition of a rhombus is that it's a polygon with four congruent sides. If you split one into two pieces with a diagonal, then yes, it will be two isosceles triangles because two sides are congruent.
Answer:
x = 4
Step-by-step explanation:
5x-50=30-15x
5x +15x =30+50
20x= 80
Divide both sides of the equation by 20
x = 4
