Step-by-step explanation:
x²=-9-27
x²=-36
there's no x
where C is the circumference, d is the diameter and r is the radius.
The diameter of a circle is a line segment that passes through the center of the circle and has its endpoints on the circle. The radius of the circle is a line segment from the center of the circle to a point on the circle. The diameter of a circle is twice the length of its radius.
If you are given the diameter then use the formula C = πd
If you are given the radius then use the formula C = 2πr
Step-by-step explanation:
Answer:
h(x) is a shift down 4 units from f(x)
Step-by-step explanation:
f(x) = abs(x+4)
h(x) = abs(x+4) -4
the -4 is a shift down 4 units
h(x) is a shift down 4 units from f(x)
Answer:
To eliminate x multiply the first equation by 3 and the second equation by 4
To eliminate y multiply the first equation by 3 and the second equation by 2
Step-by-step explanation:
We are given a system of linear equations;
4x-2y=7
3x-3y=15
solving by elimination means that we shall be getting rid of one of the variables in order to determine the other. In this case we can either eliminate x or y. In order to eliminate any of these variables, we first must make their coefficients equal in both equations. To eliminate x;
Multiply the first equation by 3 and the second equation by 4.
To eliminate y;
Multiply the first equation by 3 and the second equation by 2.
