Answer:

Do you mean 2x - 3 = 77? if so here's your answer bud,

Step-by-step explanation:

2x - 3 = 77

we can send 3 to rhs from lhs (from left hand side to right hand side)

when we send a number to another side it changes it's sign then it will be...

2x = 77+3

so, 2x = 100

now we can send 2 to rhs from lhs and then it will change it's sign from multiplication to division

so, x = \frac{100}{2}

the answer is 50 :D

Which ordered pair is generated from the equation shown below? y = 3x - 1 A. (6, 18) B. (6, 17) C. (4, 12) D. (9, 8)
geniusboy [140]

Answer:

B 6,17

Step-by-step explanation: If you plug in the value of x from each of the choices only b gives the correct value of y. If you put 6 in the place of x in y= 3x-1    then y= 18-1 which is 17, and it does say 17 in 6,17.

No because they are straight lines, they cannot curve to intersect more than once, think of a capital X.

(x-2) is a factor of x^2-3x^2+kx+14. The value of k is?​
BartSMP [9]

Answer:

k = 5

Step-by-step explanation:

I will assume that your polynomial is

x^2 - 3x^2 + kx + 14

If x - a is a factor of this polynomial, then a is a root.

Use synthetic division to divide (x - 2) into x^2 - 3x^2 + kx + 14:

 2      /      1     -3     k     14

                        2     -2    2k - 4

         -------------------------------------

               1        -1    (k - 2)   2k - 10

If 2 is a root (if x - 2 is a factor), then the remainder must be zero.

Setting 2k - 10 = to zero, we get k = 5.

The value of k is 5 and the polynomial is x^2 - 3x^2 + 5x + 14
