Answer:
y = -2x - 4
Step-by-step explanation:
Formula is y = mx + b where m is the slope and b is the y-intercept
(1, -6) (-3, 2)
The slope is -2
y = -2x + b
So let's find b, insert 2 for y and -3 for x to find b
2 = -2(-3) + b
2 = 6 + b
Subtract 6 from both sides to get b alone
-4 = b
We found what b equals (the y-intercept), which is -4
So, the equation is y = -2x - 4

Answer:
Step-by-step explanation:
$2800 - $750 = $2050
$2050 - $500 = $1550
$750 rent
$500 vacation savings
$1500 spending money
Karl: k hours
Ryan: r hours
r+k=14 hrs
r = 2k-1 hrs
Then (2k-1) + k = 14 hours; 3k -1 = 14 hours; 3k = 15 hours; k = 5 hours.
Karl worked 5 hours; Ryan worked 2(5 hours) -1 hour = 9 hours.
Answer:
B) 20
Step-by-step explanation:
Each number in the equation needs to be a whole number, since you can't have 2.5 marbles or something like that.
2/5 of 16 is 6.4
2/5 of 20 is 8
2/5 of 21 is 8.4
2/5 of 26 is 10.4
Even though 20 is the only one that works, if you wanted to be sure it's right, just divide by three after subtracting 8 (the three remaining marbles.)
20-8=12
12÷3=4
The three remaining numbers would be equal and the amount of yellow numbers is a whole number. 20 is correct

12(2x - 8) = 15
12(2x) - 12(8) = 15
24x - 96 = 15

24 24
x = 4.625
