Answer:

Step-by-step explanation:

x² -14x+50= 0

this equation has 2 solutions because is a quadratic

the solurions are imaginary roots because the discriminant is less then 0

b²-4ac = (-14)²-4*1*50 = 194-200= -6

to find the actual roots use the quadratic formula

Determine if the expressions are equivalent: 7+ 7x; 7 x + 1/7

patriot [66]

The given expressions 7+ 7x ; 7 x + 1/7 are not equivalent or equal

to each other

Step-by-step explanation:

Let us firstly assume that 7 + 7x is equivalent ( to 7(x + 1/7) so that means

7 + 7x = 7(x + 1/7)

7 + 7x = 7x + 7(1/7)

7 + 7x = 7x + 1

7x + 7 = 7x + 1

Now, subtracting 7x from both sides, we get:

7x - 7x + 7 = 7x - 7x + 1

(7 - 7)x + 7 = (7 - 7)x + 1

(0)x + 7 = (0)x + 1 thus their occurs a false statement:

7 = 1 ( we know, 7 >1)

Thus we can say that

7 + 7x is NOT equivalent to 7(x + 1/7)

Austin will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $38 and costs an ad

Nana76 [90]

38+0.11m=51+0.09m
0.02m=13
m=650 miles
If Austin will drive more than 650 miles he can choose the second plan of car renting.
If he plan todrive less than 650 miles then it's more preferable to choose the first plan of car renting
