I think the answer it 40 dollars because why would a jacket cost 48.23. If it's wrong sorry but that why I think, or maybe 45 but I don't think so.
Answer:
I hope this answer is helpful for you
Step-by-step explanation:
26.3+47.9=74.2
107.4-3.29=104.11
Answer:
210 mph
Step-by-step explanation:
speed of jet = x
headwind: speed = x - 27
time taken = 1134.6/(x - 27)
tailwind: speed = x + 27
time taken = 1469.4/(x + 27)
same amount of time:
1134.6/(x - 27) = 1469.4/(x + 27)
Cross multiply,
1134.6(x + 27) = 1469.4(x - 27)
1134.6x + 30634.2 = 1469.4x - 39673.8
334.8x = 70308
x = 210 mph
Answer:
D) y=2/9x2+2x+4
Step-by-step explanation:
y-intercept=4
2 x intercepts= 3 and 6
so y-intercept is point where x is 0 like (0,y)
x-intercept is the opposite y is 0 (x,0)
that means y-intercept is (0,4)
x-intercept is (3,0) and (6,0)
the formula of slope intercept form is
y=mx+b
b= is y-intercept
that means
y=ox^2+mx+4
x-intercept is point where y is 0
so solve
now lets try the first option
This is are quadratic functions
you need to plug in both of these until u get one that is right
change the y until you get both x's
the first option if wrong
second one y = 6x2 + 3x +4 has no x-intercepts
3rd option y=3/4x^2-6x-4
last option is y=
2/
9
x2+2 has points at -6. and -2.9999 or -3
Answer:
