Given that the meal cost is shared by Adam and his dad is in the ratio 2:3 respectively, and the amount of money paid by Adam's dad was 52.20, thus the
total cost of meal will be:
Total ratio will be (2+3)=5
total cost will be:
5/3*52.20
=87
Thus we conclude that the total cost of food was 87 pounds
Use distributive property <em>a(b + c) = ab + ac</em>
4(x + 2) - 3(7 + y) = (4)(x) + (4)(2) + (-3)(7) + (-3)(y)
= 4x + 8 - 21 - 3y = 4x - 3y - 13
Answer:
y = 4x + 1
Step-by-step explanation:
1. Solve given equation for y
4x-y=2
4x=y+2
y=4x-2
2. Parallel in linear equations means the new line will have the same slope, so your new equation so far is
y=4x+b (formula being used is linear function y=mx+b)
3. (-1,-3) is a coordinate (x,y), so plug those values in for x and y so the only variable in your equation is b, the y-intercept
-3=4(-1)+b Solve for b
-3=-4+b
1=b
4. Rewrite your new equation with the m and b you now know
y=4x+1
