Step-by-step explanation:
<u>The slope-intercept form:</u>
- y = mx + b, where m- slope, b- y-intercept
<u>Given lines:</u>
1)
- y = - 2x + 7
- m = - 2, b = 7
2)
3)
- y = -2.5x + 3.2
- m = - 2.5, b = 3.2
4)
- y = 1/4x - 2/7
- m = 1/4, b = - 2/7
Answer:
5.5+7.25−5.5−7.25 = 0
Step-by-step explanation:
To be honest, you shouldn't have to show work for an equation like this. But this is the answer. Hope it helped.
This item can be answered by the concept of ratio and proportion. The ratio of the sculpture's height and shadow should be proportional or equal to that of the person. Mathematically,
6 ft / 2 ft = h / 4 ft
The value of h in the equation is 12 ft.
Greater because it is more than 100 percent
This is even function because
1)the ends are looking in one side, both are up
2)You can see that it has line symmetry y
3) for any point
f(x)=f(-x)
f(1)=-6
f(-1)=-6
