Answer:
The best estimate for the solution of the system of equations is the ordered pair (7, 0.5)
Step-by-step explanation:
The way to solve this problem is to take a deep look into the picture, where we can see that the interception between the lines occurs right in x=7. thus, eliminating the first choice.
Next, we can see that the interception is somewhere far from the 'x' axis, hence 'y' variable can not be zero in this point.
Thus, we have our possible solution, without knowing anything else, the ordered pair (7, 0.5).
Remember, a system of equation has a solution when an interception occurs between its equations
there must be subtraction of multiplication of each two diagonal,
|G|=[12×2-(-6)×0]
=(24+0)
=24ans
Answer:
x = 3
Step-by-step explanation:
Angle D is congruent to angle B.
Angles E and B are supplementary.
180 - 101 = angle B
B = 79
Solve for x.
79 = 27x - 2
81 = 27x
x = 3
15.336 is the sum of 10.8 + 42%
The value of c for which the equation is identity is 6
Given the expression
|2x + 5|=|cx + 3 - 4x +2|
Collecting the like terms;
|2x + 5|=|cx - 4x + 3 +2|
|2x + 5|=|cx - 4x + 5|
If the <u>modulus is positive;</u>
2x + 5 = (c-4)x + 5
Compare both sides of the equation
2x = (c-4)x
2 = c-4
c = 2 + 4
c = 6
Hence the value of c for which the equation is identity is 6
