Solve the equation for c. d=a+b+c/ac
Answers
In the fraction at the end of the equation ... c/ac ... the numeratorand denominator can both be divided by 'c', and the fraction becomes 1/a .
Then the equation becomes d = a + b + 1/a
Theequation can't be solved for 'c', because there is no relationshipbetween 'c' and any of the other terms. 'c' can be anything at all, andit has no effect on anything else in the equation.
Or, to put a finer point on it, 'c' is not a function of 'a', 'b', or 'd' .

Answer:
It has a single solution x=-3 y=26
Step-by-step explanation:
The ratios of coefficients of x and y are different, so the pair of equations has one solution. It is easy to tell the first offered solution (15, 17) does not satisfy the first equation, so that choice is eliminated.
Fortunately, the second offered solution, (x, y) = (-3, 26), satisfies both equations.
The equations have a single solution: (x, y) = (-3, 26).
Answer: The equation has a single solution x = -3 , y = 26.
( -3, 26 )
Step-by-step explanation:
3x + y =17 ---------------------(1)
x + 2y = 49 -------------------(2)
Using substitution approach
From (2)
x = 49 - 2y --------------------(3)
Now put (3) in equation (1) and solve.
3(49 - 2y) + y = 17
Open the bracket and solve
3 x 48 - 3 x 2y + y = 17
147 - 6y + y = 17
Gather like terms
-5y = 17 - 147
-5y = -130
Multiple through by (-1)
5y = 130
Divide by 5
y = 130/5
y = 26.
Substitute for y now in equation (3) to get the value of x
3x + y = 17
3x + 26 = 17
3x = 17 - 26
3x = -9
Now , divide by 3
x = -3
The equation had a single solution of x = -3 , y = 26
Chech.
3 x -3 + 26
-9 + 26
= 17

( 2)( -13)
trial enderor
after some times
(3x+13)(7x-2)=0
set to zero
3x+13=0
3x=-13
x=-13/3
7x-2=0
7x=2
x=2/7
x=-13/3 or 2/7
it would be easier to use quadratic formula though

Answer:
I'd say 100 m
Step-by-step explanation:
If 1 inch = 50 miles, all you really have to do is measure the line by inches. When I measure it in full-screen, it's about 2 inches.
Also, if you're not sure, that line is too long to be just and inch.
*The length of your tip to your knuckle on your thumb is about an inch.

Answer:
A.
Step-by-step explanation:
To get to the answer, add both f(x) and g(x) together. This would be (2x^2 +3x -4) + (-4x^2 + 5x - 8). Remember that adding a negative number is the same as subtracting the positive of that number, for example, 3 + (-4) is the same as 3 - 4.

1. The factors of 15 are 3 and 5 or 1 and 15. You are looking for the pair that is two apart, which are 3 and 5. Because they add up to be negative 2, 5 must be negative, so the two numbers you get are 3 and -5. The rest can be solved similarly:
2. (Out of 1 and 32, 2 and 16, and 4 and 8, only 4 and 8 works) -8+4=-4, -8*4=-32
3. (Out of 1 and 14, and 2 and 7, only 2 and 7 works) -7+2=-5, -7*2=-14
4. (Out of 1 and 24, 2 and 12, 3 and 8, and 4 and 6, only 3 and 8 works) -3+8=5, -3*8=-24.
Answer:
-3 + 8 = 5, -3 · 8 = -24
