Answer:
y= -7x-8
Step-by-step explanation:
The slope intercept form is y = mx + b.
First, find the slope. Use rise/run which gives you -7. <= negative bc its a negative slope.
Next, find the y intercept for b. It is -8.
Now, combine the numbers. y = -7x-8.
Answer:
The length of BC is 17
Step-by-step explanation:
When we construct a triangle with the data, we will end up a isosceles triangle.
In a isosceles triangle , we know that tow angles and two sides are equal
The questions states that

Then sides AC and AB are also equal
On equation their values
2X - 8 = X+9
2X = X + 9 +8
2X = X + 17
2X - X = 17
X = 17
The length of BC = X = 17
Answer:
b. 4
Step-by-step explanation:
Answer: 6 km to 22 km !
Step-by-step explanation:
the distances from the school mall to bus station could be, in the worst case, 14+8=22 km apart, and in the best case 14-8=6 km apart
so the range is 6 km to 22 km !
