Step-by-step explanation:
5780 / 288 = ~ 20 times warmer
In other words, 20 times the earth surface temp is the sun surface temp.
2x-y=4
X+2y=2
A) no solution
B) one solution
C) infinitely many solutions
Answer:
B) one solution
Step-by-step explanation:
The ratio of x-coefficient to y-coefficient is different in the two equations, so the lines have different slopes. Two lines with different slopes will always have exactly one point of intersection. You don't need to graph the equations to know there is ...
one solution
__
A graph is attached. As it happens, the two lines are perpendicular. The solution is (2, 0).
Answer:
6.32

6.32455532034 would be the answer..
Rounded to the nearest tenths would be 6.32
Hope this helps!! :D
The value -0.07 is the negative real number in the quadratic equation 0 = x² – 5x – 4
Any equation of the form where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
We have a quadratic equation;
0 = x² – 5x – 4 or
x² – 5x – 4 = 0
Here a = 1, b = -5, and c = -4
After simplification:
x = 5.70 or x = -0.70
The value x = -0.70 is the negative real number.
Thus, the value -0.07 is the negative real number in the quadratic equation 0 = x² – 5x – 4
