Answer:
2
Step-by-step explanation:
where both lines intersect
therefore 2 and 5 are the two solutions
8-5=-3 It's negative 3 because the 8 is greater than 5
Answer:
100 is correct answer
Step-by-step explanation:
when ever anything ² , it means that number is multiplied by itself.
in above we multiple 10 with 10 and we get 100.
hope it helped you:)
First, you have to set up two equations.
X + y = 45
18x + 24y = 1,050
To do this, you have to solve for an exponent by cancelling out the other one. To solve for y, you multiply everything in the first equation by -18.
-18x -18y = -810
This cancels out the x and leaves you with 6y = 240. Divide both sides by 6 and you have the number of Yankee hats that were bought.
Then, you have to substitute 40 for y in the first equation and solve for x.
Answer:
2x+y = 20
Step-by-step explanation:
The equation for a line is y = mx+b where m is the lope and b is the y intercept
y = -2x+b
substitute the point into x and y
8 = -2(6) +b
8 = -12+b
Add 12 to each side
20 =b
y = -2x+20
Add 2x to each side
2x+y = 20
