Answer:
6,251
Step-by-step explanation:
First you have to multiply 65 by 7 you will get 455
Then you have to multiply 144.9 by 40 you will get 5,796
At last add the two values:
5,796+455=6,251
Answer:
y=4x
Step-by-step explanation:
y=mx+b is our frame equation for a linear function.
b=the y intercept, or when the line crosses the y axis, whenever x=0, so in this chart it is (0,0), b=0
y=mx+0
m= the slope, to find m you can either use the slope formula or plug in a point and solve for m
8=m(2) + 0
m=4
we don't need to put 0 in our final answer because it doesn't change anything
Answer:
-1
Step-by-step explanation:
let,x=-1
f(x)= 12/4x + 2
f(-1)= 12/4x(-1) + 2
=12/(-4) +2
= -3+2
= -1
Answer:
Center: (4,8)
Radius: 2.5
Equation: 
Step-by-step explanation:
It was given that; the endpoints of the longest chord on a circle are (4, 5.5) and (4, 10.5).
Note that the longest chord is the diameter;
The midpoint of the ends of the diameter gives us the center;
Use the midpoint formula;

The center is at; 
To find the radius, use the distance formula to find the distance from the center to one of the endpoints.
The distance formula is;




The equation of the circle in standard form is given by;

We substitute the center and the radius into the formula to get;


Answer:

Step-by-step explanation:
Equation - 
Solve - subtract 2 from both sides -
