Answer:
Step-by-step explanation:
Given :
l + m + n = 9
l²+ m² + n²= 31
l + m + n = 9
On squaring both sides
(l + m + n)²= 9²
(l²+m²+n²+2(lm+mn+nl) = 81
31 +2(lm+mn+nl) = 81
2(lm+mn+nl) = 81 - 31
2(lm+mn+nl) = 50
(lm+mn+nl) = 50/2
(lm+mn+nl) = 25
Hence, the value of (lm+mn+nl) = 25
13 - 4 / 6 - 0
9/6 = 3/2
3/2 is the slope!
To simplify the equation, you just have to add like terms. This means adding 9.63 and 7.5. Once you've found your sum, which is 17.13, your equation will be <em>N+17.13.</em>
Answer:
The y-intercept is -21. The x-intercept is -10.5 or
.
(0, -21) and (-10.5, 0)
Step-by-step explanation:
To find the y-intercept, you would plug in 0 for x.
y = -2x - 21
y = -2(0) - 21
y = 0 - 21
y = -21
The y-intercept is -21.
To find the x-intercept, you would plug in 0 for y.
y = -2x - 21
0 = -2x - 21
2x = -21
x = -21/2
x = -10.5 or 
The x-intercept is -10.5 or
.
