Josh did not follow the order of operations , he should have done 8x divided by 2 first but instead he did 4x- 8x
The correct solution...
4x-8x / 2
4x -4x
0
The solution should be zero (0)
Hope it helps!
Answer:
Pythagorean Theorem is for triangles not circles.
The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the center.
Plug in your given information and simplify.
(x - (- 1))² + (y - 2)² = (3)²
(x + 1)² + (y - 2)² = 9 is your equation.
Algebra Examples
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values.
Answer:
x = 40°
Step-by-step explanation:
Measure of external angle outside a circle = ½ of the difference of the measurements of the intercepted arcs
Thus:
m<T = ½(arc PQ - arc RS)
x/2 = ½[(x + 70) - (x + 30)]
Multiply both sides by 2
x = (x + 70) - (x + 30)
x = x + 70 - x - 30 (distributive property)
Add line terms
x = x - x + 70 - 30
x = 40°
1. m<13
2. y>2
3. p>-3
I don't know the answers for the last two
