So slope intercept form y=mx+b slope is m
m=6 so
y=6x+b
this is not the legit way but it works so
put in 3 for x and 4 for y and solve for b
4=6(3)+b
4=18+b
-14=b
b=-14
the slope intercep form is y=6x-14
So x + y = 45, and 4x + 5y = 195. Get y by itself. Subtract x from both sides in the first equation to get y = 45 -x, and subtract 4x from the second equation to get 5y = 195 - 4x. Divide by 5 to both sides to get y = 39 - 4/5x. 39 - 4/5x = 45 - x. Add x to both sides to get 39 - 1/5x = 45. Subtract 39 from both sides to get -1/5x = 6. Divide by -1/5 to get x = -30, or 30. In the first equation, do 30 + y = 45. Subtract 30 from both sides to get y = 15. Check. 4(30) + 15(5) = 195, or 120 + 75 = 195.
Answer:
B. -500
Step-by-step explanation:
U can find the unit rate by looking where is the point so in that pic the unit rate I see is: 3/5
Julie cannot be right. That's because if you add three odd numbers together, <em>you always get an odd number. </em>The number 50 is an Even number.
Let's try adding 3 odd numbers together a couple of times...3 + 3 + 3 = 9 5 + 1 + 5 = 11 7 + 3 + 5 = 15
We tried 3 examples, we could not get any even number. So,
Julie's claim is wrong.
