Answer:
x = 35/22
y = 3/22
Step-by-step explanation:
y= 2/5x-1/2 ................(1)
y=-1/3x+2/3 ...............(2)
10*(1)
10y = 4x -5 ...................(1A)
3*(2)
3y = -x +2 ....................(2A)
To find intersection, solve for y & x
4(2A) + (1A)
12y+10y = -4x+4x +8-5
22y = 3
y = 3/22
Substitute in (1)
3/22 = 2/5x -1/2
multiply by 110
15 = 44x - 55
70 = 44x
x = 70/44 = 35/22
First change the fraction to decimals or common denominators.
3/4 = 0.75 and 1/5 = 0.2
0.75 + 0.2 = 0.95 = 95/100 = 19/20
(3/4) = (15/20)
(1/5) = (4/20)
(15/20) + (4/20) = 19/20
Answer:
y = 7/5x + 18/5
Step-by-step explanation:
so we have y = mx + b
f(1) = 5
f(-4) = -2
so let's find b
so like if you do (5 - (-2))/(1 - (-4)) you get (5 + 2)/(1 + 4) = 7/5
y = 7/5x + b
so now we can plug in a value like f(1) = 5
5 = (7/5)1 + b
b = 18/5

b 2 to the second -5
