Setting y=0, we can solve the quadratic equation or factor the polynomial to
(5x-1)•(5x-1) = 0
(5x-1)^2 = 0
5x-1=0
x=1/5 or 0.2
So there is only one root and the function intersects the x-axis at only one point.
The answer is B. 1.
The range of the function c = 50t + 200 is given by [200, ∞).
<h3>What is a
linear equation?</h3>
A linear equation is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the y intercept.
Let c represent the distance travelled in t hours, hence:
c = 50t + 200
The range of the function c = 50t + 200 is given by [200, ∞).

Answer: y = x + 5
Step-by-step explanation:
y = mx + b
m = (given)
b = 5 (given b/c it's your y-intercept)
^if you aren't sure about y-intercept you can always plug the point in:
5 = (0) + b
5 = b
y = x + 5
now just graph (start from 5 on y-axis & go up 1, over 8)
