Answer:
B. y=1/2x-5
Step-by-step explanation:
From the graph, we read the slope of line JK.
slope = rise/run = -3/-6 = 1/2
The equation we need has the same slope.
y = mx + b
y = (1/2)x + b
It passes through point P(6, -2). Now we find b.
-2 = (1/2)(6) + b
-2 = 3 + b
b = -5
The equation is
y = (1/2)x - 5
Answer:
6F
Step-by-step explanation:
Let x be the temperature at noon
dropping means we subtract
The temperature at 9 pm was -4. That goes on the right hand side of the equals
x-10 = -4
Add 10 to each side
x-10+10 = -4+10
x = 6
The temperature at noon was 6 F
Step-by-step explanation:
Answer:
i think it's 11x-1
Step-by-step explanation:
2(1-3x)-(5x+1)
2-6x-5x-1
2-11x-1
11x-1
X<12
<span>5(x+5)<85 </span>
<span>5(x + 5)/5 < 85/5 </span>
<span>x + 5 < 17 </span>
<span>x + 5 - 5 < 17 - 5</span>
