Answer:

x = -2/5

x = 1

Step-by-step explanation:

5x² - 3x - 2 = 0

(5x + 2)(x - 1) = 0

⇒ 5x = -2

⇒ x = -2/5

⇒ x - 1 = 0

⇒ x = 1

What is the rate of change of the linear relationship modeled in the table? (4 points) x y −2 5 −1 4 0 3 1 2 a −2 b −1 c negativ
Ostrovityanka [42]

Answer:

rate of change=slope= y2-y1/x2-x1

Step-by-step explanation:

x: -2|-1|0|1

y : 5|4|3|2

so choose 2 ordered pairs. in this case, we will choose (-2,5) and (-1,4)

now we plug them in: \frac{4-5}{-1-(-2)}

4-5=-1

-1-(-2)=1

so -1/1 is equal to -1, meaning it's answer option b.

Joy Wigens, who works at Putnam Investments, received a check for $2,670. She deposited 1/3 of the check in her Citibank account
spin [16.1K]

Answer: $1,780

Step-by-step explanation:

Joy Wigens deposited 1/3 of the check of $2,670 that she received in her Citibank account.

The amount she deposited in her Citibank account was:

= 1/3 * 2,670

= $890

The amount she is left with after this deposit will therefore be:

= Check amount - deposit at Citibank

= 2,670 - 890

= $1,780
