Mathematics
1 answer:
EleoNora [17]2 years ago
8 0

Answer:

Step-by-step explanation:

-7k = 0

Divide both sides by (-7)

k = 0

17) c - 4 = -23

Add 4 to both sides

c - 4 + 4 = -23 + 4

           c = - 19

18) \dfrac{r}{-2}=-16\\\\\\Multiply \ both \ sides \ by \ (-2)\\\\\dfrac{r}{-2}*(-2) = (-16)*(-2)\\\\\\r = 32

Which equations are true for x = –2 and x = 2? Select two options
fomenos

Answer:

Number 1 and Number 4

Step-by-step explanation:

By factoring, you can figure out the roots (x = -2 or x = 2)...

1. x^2 - 4 = 0

--> (x + 2)(x - 2) = 0

--> x = -2, x = 2

2. x^2 + 4 = 0

--> factors weirdly, so I won't write it. You'd have to use the quadratic formula.

3. 3x^2 + 12 = 0

--> 3 (x^2 + 4) = 0

--> factors weirdly (same as above)

4. 4x^2 - 16 = 0

--> 4 (x^2 - 4) = 0

--> 4 (x+2) (x-2) = 0

--> x = -2, x = 2

5. 2 (x-2) 2 = 0

--> x = 2

Two numbers that have a sum of 100 and a diffrence of 6
Genrish500 [490]

Answer:

50 + 50 = 100 bus the difference is 0

(50 + 3) + (50 - 3) = 100 and the difference is 6

53 and 47 are the numbers

other way

I. x + y = 100

II. x - y = 6

I + II 2x = 106 --> x = 53

53 + y = 100 --> y = 47
