Slope is -4 and y intercept is 7. Whatever the number in front of the X is, that will always be your slope. Anything added or subtracted after the x, that’s your y intercept! Hope I helped.
He made a mistake in step #2. It seemed to be a trivial mistake because it involved signs, but it still had a great impact. Since step#2, his solution was already wrong.
Instead of
(-1)²-4(2)(-6) = 1 + 48 = 49
What he did is
(-1)²-4(2)(-6) = -1 + 48 = 47
Answer:
9 miles
Step-by-step explanation:
A 6+3 is nine
You have to use the Pythagorean theorem a squared plus b squared is c squared so 13 squared plus 18 squared equals c squared. 13x13=169 18x18=324 169+324=493 so c squared is 493 to get c you square root 493 which equals 22.2 so the diagonal, c, is 22.2 centimeters long
I think that when you asked this question, no one answered because there is not enough information. I also got this problem and there is in fact, a table and a graph.
Step-by-step explanation:
for Hector, it only shows a y and x graph and for Geri it shows a table. let´s call the graph the ¨h¨ graph (for Hector) and the table is going to be called the ¨g¨ graph (for Geri)
on the h graph, it shows that y/x = dollars/time for Hector,
on the g table, it shows that Geri is getting paid $25.50 for each 3 hours and it keeps increasing within each input and output.
your y = your dollars
your x = your time
we are looking for slope and we need $15 over hours
15/x
the answer is that Hector earns $6.50 more than Geri
