X+7=-8
You are trying to get x on its own so you will subtract 7 from both sides.
x+7-7=-8-7
This simplifies to x= -8-7
A negative plus a negative equals a negative. So -8-7 equals -15
Your final answer is x=-15
Answer:
40 cm
Step-by-step explanation:
1 km = 10^5 cm, so 8 km = 8×10^5 cm
The map distance is 1/20,000 = 5×10^-5 of the real distance, so the map distance is ...
(5×10^-5)(8×10^5 cm) = 40 cm
B i thaink is the correct one
Answer:
<h2>11x - y = -79</h2>
Step-by-step explanation:
The standard form of an equation of a line:
The point-slope form of an equation of a line:
m - slope
(x₁, y₁) - point
We have the points (-7, 2) and (-8, -9). Substitute:
Convert to the standard form:
<em>use the distributive property </em>a(b + c) = ab + ac
<em>add 2 to both sides</em>
<em>subtract 11x from both sides</em>
<em>change the signs</em>
