Answer:
y=-1
Step-by-step explanation:
The slope intercept form of a line is
y = mx +b where m is the slope and b is the y intercept
We know the slope is zero
y = 0x+ b
Substituting the values for x=-1 and y=-1 from the point we are given
-1 =0 +b
b=-1
Putting this into the original equation
y = 0x+-1
y=-1
Answer: x= 42.3
Step-by-step explanation:
Sqrt a^2 + b^2 - (2ab)(cos 100)
Sqrt 25^2 + 30^2 - (2)(25)(30)(cos 100)
42.3
Answer:
60 cm?
Step-by-step explanation:
The Amanda's house is 6.7 km far from her school.
<u>Step-by-step explanation:</u>
From the given information,
- The Amanda's school is due west of her house forms the base.
- The school is due south of the Shereen's house forms the height.
- The straight-line distance between Amanda's house and Shereen's house forms the hypotenuse.
Therefore, It can be determined that it forms the right angle triangle.
It is given that,
The distance between the school and Shereen's house is 2 kilometers.
That is, the height of the triangle = 2 km
The straight-line distance between Amanda's house and Shereen's house is 7 kilometers.
That is, the hypotenuse of the triangle = 7 km
Now, the distance between the Amanda's house and her school is the base of the triangle.
<u>To find the base :</u>
Base = 
⇒ 
⇒ 
⇒ 
⇒ 6.7 km
Therefore, the Amanda's house is 6.7 km far from her school.
