Answer:
slope intercept form: y=1/2(x)+7
Step-by-step explanation:
slope intercept form is written as y=mx+b
on a graph, the equation y=8y-4x=56 goes through the "x" axis at point (-14,0) and the goes through the "y" axis at point (0,7)
<span>In the question "Susu is solving the quadratic equation 4x2 – 8x – 13 = 0 by completing the square. Her first four steps are shown in the table.
In which step did Susu first make an error?"
Susu made her first error in step 2, when she factored out 4 she is supposed to divide 8x by 4.
Thus the correct expression for step 2 should be 4(x^2 - 2x) = 13
To complete the solution for the equation:
4(x^2 - 2x + 1) = 13 + 4(1)
4(x - 1)^2 = 13 + 4
4(x - 1)^2 = 17
(x - 1)^2 = 17/4
x - 1 = +/- sqrt(17/4)
x = 1 +/- sqrt(17) / 2</span>
In 90 minutes it would travel for 1 hour because 90 minutes is 1 hour
hope this helps
