Do you need to find the m?
If yes so the solution will be like that
(10- -20) / (5- - 10) = (10+20)/(5+10) = 30/15= 2

Which number is in the correct format for scientific notation?
olchik [2.2K]

Answer:

The answer to your question is: letter A

Step-by-step explanation:

Rules for using scientific notation:

1.- The number before the decimal point must be between 1 and 10.

2.- Determine the exponent

3.- It must be in decimal format, ( x 10)

A 3.8*10^12       This number is in correct scientific notation.

B 33.8* 10         This number is incorrect, because before the decimal point the number must be between 1 and 10.

C 3.8 *20^8      This number is incorrect because the power must be 10 not 20.

Solve the system of equations. y = x − 5 and y = x2 − 5x + 3 A. (-4,-9) and (-2,-7) B. (4,-9) and (2,-7) C. (4,-3) and (2,-1) D.
larisa [96]

Answer:

D

Step-by-step explanation:

Given the 2 equations

y = x - 5 → (1)

y = x² - 5x + 3 → (2)

Substitute y = x² - 5x + 3 into (1)

x² - 5x + 3 = x - 5 ← subtract x - 5 from both sides

x² - 6x + 8 = 0 ← in standard form

(x - 2)(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x - 4 = 0 ⇒ x = 4

Substitute each of these values into (1) for corresponding values of y

x = 2 → y = 2 - 5 = - 3 ⇒ (2, - 3 )

x = 4 → y = 4 - 5 = - 1 ⇒ (4, - 1 )
