Answer:
The solution I got is (4,2)
Step-by-step explanation:
When I plotted the equations on a graph, they intercepted at (4,2).
The answer should be 320 rods = 1 mile 5280 ft= 1 mile
Hope this helps you
Answer:
70
Step-by-step explanation:
"75% more customers than last week" means (100% + 75%) of 40, or
1.75(40 customers) = 70 customers this week
Beforehand let me apologize for my sloppy handwriting. I'm a lefty, so please deal with me. . Anyway, the equation you listed didn't really have a x, because a linear equation is y= mx+b, and anything with x is the slope. But I did see y and a number on one side, so I'm like maybe I can get these two alone. So here's what I did:
2y + 4=0
-4 -4 I subtracted 4 on both sides. Why because you would want "y" alone.
Next,
2y= -4
Now to get "y" alone you want to divide on both sides.
2y= -4/ 2
y= -2
Now you're probably thinking "how do you graph it? There's no "x" in the equation." Well, you just graph it. Since the answer is y= -2, you go to the y axis, look for -2, and place a line to indicate that is the equation. And to make it clear, remember y is the y-intercept.
I really do hope this helps you, if not message me. I'll be happy to help, and again I'm sorry for my handwriting!
