Answer:
eleven below zero
Step-by-step explanation:
opposite of -11 =11 so that doesn't work
positive eleven=11 so that doesn't work
eleven greater than zero=11 so that doesn't work
eleven below zer0= -11 so it works
Answer:
Step-by-step explanation:
<u>Use two ordered pairs from the table to find the slope of f(x):</u>
- (-4, - 9) and (6, 6)
- m = (6 - (-9)) / (6 - (-4)) = 15/10 = 1.5
<u>Find the equation of f(x) using point-slope form:</u>
- y - y₁ = m(x - x₁)
- y - (- 9) = 1.5(x - (-4))
- y + 9 = 1.5(x + 4)
<u>The y-intercept is the value of y when x = 0:</u>
- y + 9 = 1.5*4
- y + 9 = 6
- y = - 3
<u>Use two points on the graph and find the slope of g(x):</u>
- (0, 4) and (1, - 3)
- m = (- 3 - 4) / 1 = - 7
<u>Find the required sum:</u>
Answer:
300
Step-by-step explanation:
every lamp can connect other lamps ,from the first ,it can connect the other 24 lamps,and then, the second ,can also connect other 24 。but the line between the first and the second is counted twice。
so it would be:
(1+2+3+...+24)×24÷2=300
