Answer:
x=1,y=3
correct answer is (1,3)
Step-by-step explanation:
We can quickly eliminate y by subtracting one equation from the other
(-2x+y=1)-(-4x+y=-1)
2x=2
x=1
plug x=1 into equation 1
-2(1)+y=1
y=1+2=3
Answer:
75%
Step-by-step explanation:
Total = 21 + 7
= 28 cupcakes
Vanilla cupcakes = 21 / 28 x 100
= 0.75 x 100
= 75%
Slope of the line = (4--1) / (8-2) = 5/6
point slope form is y-y1 = m(x-x1) where m=slope and (x1,y1) is a point on the line
so the answer to (a) is y + 1 = (5/6)(x - 2) Answer
(b) multiply the above equation by 6:-
6y + 6 = 5(x - 2)
6y + 6 = 5x - 10
5x - 6y = 16 is the equation in standard form Answer
The answer is 6.4008 meters or rounded is 6.4
