P.s. if any question is wrong then I'm sorry. :(
Step-by-step explanation:
question 4
y=2x^2-5x+9
y= 2x^2+5x-1
y= 2x^2-5x+9=2x^2+5x-1
x=1
y= 2×1^2+5×1-1
y=6
Paula = 6 video games
Myles = 1 video game + Paula(6 video games)
P + M = Total video games
M = 1 + P
P = 6
P + M = 6 + 1 = 7
The unit price per kg is $5, to find this divide the 9 kilograms into the price $45 the answer is what each kilogram is worth
Y=mx+b
m=0.5
b is value of y in y-intercept, b=-2
The equation of this line is
y=0.5x-2
When x=4
y=0.5x-2=y=0.5*4-2=2-2 = 0
When x=4, y=0.
