C. (2x - 5)

<u>Explanation:</u>

Given:

The factors of 4x^2 - 25 = ?

The binomial factor can be simplified and written as

4x^2 - 25 = (2x + 5) (2x - 5)

When these two factors are multiplied then they give 4x² - 25

Thus, (2x + 5) and (2x - 5) are the two factors of 4x² - 25

Y = -1/3 x + 2
dangina [55]

Answer:

X = 0

Y = 2

so Option A (0,2) IS CORRECT

Step-by-step explanation:

Y = -1/3 x + 2 equation 1

Y = x+ 2 equation 2

from equation 2 we have

y = x+ 2 Put in equation 1

x + 2 = -1/3 x + 2

x +1/3x = 2 -2

0.67 x = 0

X = 0

so put x =0 in equation 2 then we have

y = x +2

Y = 0+ 2

Y = 2

3. What is the value of the expression 5x -2 when = 3/4
yaroslaw [1]

Answer:

Step-by-step explanation:

Pay attention to the procedure:

(5(10)^2)^3/(10(5))^4. What we need is plug in the corresponding x and y values Then you have to do x squared before you multiply it by 5 like this: (5(100))^3/(10(5))^4 Now solve for what is in the top parenthesis. (500)^3/(10(5))^4 500^3=125000000 Now work on the denominator. Do what is inside the parenthesis first 10*5=50 Now (50)^4=6250000 Now divide the numerator and the denominator. 125000000/6250000 Which equals 20, Please check if I'm wrong but I think this is what you need
