1. Replace x with the given values and see if the equation equals the Y value:
y = -5x +4
-5(5)+4 - -25 +4 = -21
The answer is D.
2. -4 = g+1
Subtract 1 from each side:
-5 =g
The answer is C.
3. The 2nd chart is correct, ( the top one on the picture with 2) because when Tony is 5 the line is on Y = 0, when the line is on 6 it is on Y=1, which keeps Tony at 5 years older.
Answer:
Step-by-step explanation:
let : x and t this numbers : x +y = -81/4
y == -52/3
x + (-52/3) = -81/4
x = -81/4 + 52/3........continue
Answer:
a. y = (3/5)× x +1
Step-by-step explanation:
y= mx+c
m = (13-4)/(20-5) = 9/15 = 3/5
c= 1
so, y= mx+c becomes y= (3/5) × x +1
