Answer:
X2+8X+6=0
We add all the numbers together, and all the variables
X^2+8X+6=0
a = 1; b = 8; c = +6;
Δ = b2-4ac
Δ = 82-4·1·6
Δ = 40
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
X1=−b−Δ√2aX2=−b+Δ√2a
The end solution:
Δ−−√=40−−√=4∗10−−−−−√=4√∗10−−√=210−−√
X1=−b−Δ√2a=−(8)−210√2∗1=−8−210√2
X2=−b+Δ√2a=−(8)+210√2∗1=−8+210√2

Answer: B) 6x - 6 = 15x + 15
Step-by-step explanation:
To find our answer, we need to first work out each equation.
A) 6x - 15 = 6x + 15
First, cancel out the equal terms.
6x - 6x - 15 = 15
-15 = 15
This statement is false.
B) 6x - 6 = 15x + 15
-9x = 21
x = -7/3
<u>This statement has one solution. </u>
C) 6x - 6 = 6x + 15
-6 = 15
This statement is false.
D) 6x + 15= 6x + 15
15 = 15
This statement has infine solutions.
Answer:
me tooo plzzz some one slove this
This looks like an ellipse.
Complete the square for y: 9(y²-6y-7)=9(y²-6y+9-9-7)=9((y-3)²-16).
Rewrite the equation:
4x²+9(y-3)²-144=0; 4x²/144+9(y-3)²/144=1; x²/36+(y-3)²/16=1.
Standard equation of an ellipse is (x-h)²/a²+(y-k)²/b²=1, where (h,k) is the origin or centre.
This is the equation of an ellipse with centre (0,3), a=6 and b=4 (semimajor and semiminor axes).

hy dude i don't have exact answer but you can go through below equation
Step-by-step explanation:
A unit rate is a ratio between two different units with a denominator of 1. To calculate the unit rate, divide the numerator by the denominator. The resulting decimal number is the unit rate.
