Answer:
-5
Step-by-step explanation:
Answer:
x = 34°
y = 15
Step-by-step explanation:
x + 146 = 180
x = 34°
4y + 8 + 5y + 3 + 34 = 180
9y + 45 = 180
y = 15
Answer:
- 3x² + 5x + 1 = 0 simplified
- x = (-5 ±
)/6 roots
Step-by-step explanation:
<u>Given quadratic formula</u>
<u>Standard form</u>
<u>Simplifying</u>
- 3x² + 5x - 5 + 6 = 0
- 3x² + 5x + 1 = 0
<u>Solving</u>
- x = (-5 ±
)/(2*3) - x = (-5 ±
)/6
Let
x-----> the number of hours that Candice spent doing her homework
y-----> the number of hours that Ronald spent doing his homework
we know that

convert mixed number to an improper fraction

so
-------> equation A
------> equation B
Substitute equation A in equation B

convert an improper fraction to a mixed number

therefore
<u>the answer is the option B</u>

we conclude that the center of the circle is the point (-5, 0).
<h3>How to find the center of the circle equation?</h3>
The equation of a circle with a center (a, b) and a radius R is given by:

Here we are given the equation:

Completing squares, we get:

Now we can add and subtract 25 to get:

Comparing that with the general circle equation, we conclude that the center of the circle is the point (-5, 0).
