You just need two points to graph a line.
When x = 1
y - 4 = -1/4(1 - 5)
y - 4 = -1/4(-4)
y - 4 = 4/4
y - 4 = 1
y = 5
So, we have our first point, (1,5)
When x = 2
y - 4 = -1/4(2 - 5)
y - 4 = -1/4(-3)
y - 4 = 3/4
y = 4 3/4
Now we have the point (2, 4 3/4)
Now just run a line through the two points and you're done!
Answer:
Step-by-step explanation:
since 3 * 15 = 45, we know that we have to multiply 5 by 15. so the ratio would be 45:75. I hope this helps!
Answer:
7 hours
They worked together for 7 hours ($350 + $120)
Answer:

Step-by-step explanation:
Isosceles triangles are a type of triangles in which two of their sides have an identical length. It should be noted that the angles opposite the sides that are the same length are also the same. This means that these triangles not only have two equal sides, but also two equal angles.
You can solve this problem using different methods, I will use pythagorean theorem. First take a look at the picture I attached. As you can see:

And we can find a easily using pythagorean theorem:

Solving for a:


Therefore:

Answer:
= 52°
Step-by-step explanation:
The obtuse angle at O is twice the angle made at the circumference /by the same segment b.
=52×2=104°
The base angles that are made by isosceles triangle that has the apex with angle 104° equal to (180-104)/2=38°
The radii of a circle are equal and meet tangents at right angles.
Angle a= 90-38= 52°
