Answer:

15)b<16

17)c>25

Step-by-step explanation:

15)b/4<4

Multiply both sides by 4. Since 4 is positive, the inequality direction remains the same.

b<4×4

Multiply 4 and 4 to get 16.

b<16

17)5c>125

5c>125

Divide both sides by 5. Since 5 is positive, the inequality direction remains the same.

c=125/5

Divide 125 by 5 to get 25.

c>25

Answer:

AC = 38

Step-by-step explanation:

AB = BC

4 - 5x = 2x + 25

-7x = 21

x = -3

AC = 2(BC) = 2(2x + 25) = 4x + 50 = 4(-3) + 50 = -12 + 50 = 38

AC = 38

X2 +x − 4 = 0

Rus_ich [418]

Answer:

a=1
b=1
c=-4
x = (-1 ±√17)/2

Step-by-step explanation:

The coefficient of x^2 is "a". That is 1.

The coefficient of x is "b". That is 1.

The constant term is "c". That is -4.

The values of a, b, and c are 1, 1, and -4, respectively.

_____

The solution is ...

x = (-b ±√(b^2-4ac))/(2a)

Filling in the values of a, b, and c, this is ...

x = (-1 ±√(1^2 -4·1·(-4)))/(2·1)

x = (-1 ±√17)/2
