Answer:
(4.0) and (6.0)
Step-by-step explanation:
when the function cross the x- axis
the y-coordinate equals to zero
x2 - 10x + 24=0
x=6,4
y=0
10008 hours per 3 years is average of 3336 hours per year, or about 9.1 per day.
Answer:
(5,6)
Step-by-step explanation:
8X +6Y=4
Y=-3X+9
Substitute the second equation into the first. Every place you see y put -3x+9)
8x +6(-3x+9)=4
Distribute
8x-18x +54 = 4
Combine like terms
-10x +54 = 5
Subtract 54 from each side
-10x +54-54=4-54
-10x = -50
Divide by -10
-10x/-10 = -50/-10
x= 5
Now we need to find y
y = -3x+9
y = -3(5) +9
y = -15+9
y= 6
(5,6)
The equation of a linear function: y = mx + b
x = y - 3 → y - 3 = x <em>add 3 to both sides</em>
y = x + 3 <em>it's a linear function!</em>
y = x³ + 2 NOT, because we have x³
y = 6x² NOT, because we have x²
y = 2/(3x) NOT, because x is in denominator.
