You determine whether the parabola opens upward, with a positive x^2. It opens downward with a negative x^2.
f(x) is a maximum
g(x) is a minimum
Answer:
x=10 n=18.5 s=6
Step-by-step explanation:
4x-10=30
Add 10 to both sides
4x-10+10=30+10
4x=40
Divide by 4 on both sides
(4x)/4=40/4
x=10
2n-7=30
Add 7 to both sides
2n-7+7=30+7
2n=37
Divide by 2 on both sides
(2n)/2=37/2
n=18.5
(s/3)+2=4
Subtract 2 from both sides
(s/3)+2-2=4-2
(s/3)=2
Multiply by 3 on both sides
3s/3=2*3
s=6
Answer:
The equation of the line with slope 6 and containing the point (0, 4) will be:

The graph of the line y = 6x+4 is attached below.
Step-by-step explanation:
The slope-intercept form of the line equation

where
Given
The y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
The point (0, 4) indicates that:
at x = 0, y = 4
Thus, the y-intercept b = 4
now substituting b = 4 and m = 6 in the slope-intercept form of the line equation


Thus, the equation of the line with slope 6 and containing the point (0, 4) will be:

The graph of the line y = 6x+4 is attached below.
Answer:
£5.04
Step-by-step explanation:
Let's first find the unit cost.
£3.60/2.5kg = £1.44/kg
To find out how much money 3.5kg of apples costs, we simply need to multiply the unit price by 3.5.
£1.44/kg * 3.5kg = £5.04.
Answer:x=9
Step-by-step explanation:
X=9-8=37
(5x9)-8=37
45-8=37
