Answer:
Step-by-step explanation:
someone needs to answer this like rly
0.91 = 91/100 = 91%
That's basically it
Answer:
see explanation
Step-by-step explanation:
I will begin with part two, first.
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius.
Given
x² - 18x + y² - 10y = - 6
Using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(- 9)x + 81 + y² + 2(- 5)y + 25 = - 6 + 81 + 25, that is
(x - 9)² + (y - 5)² = 100 ← in standard form
with centre = (9, 5 ) and r = = 10

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
3x + y = 10
y = x + 2
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 3x + (x + 2) = 10
- Combine like terms: 4x + 2 = 10
- Isolate <em>x</em> term: 4x = 8
- Isolate <em>x</em>: x = 2
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = x + 2
- Substitute in <em>y</em>: y = 2 + 2
- Add: y = 4
