I=PRT
I=Interest
P=principal
R=rate in decimal
T=time in years
1year=12months
72months/12months=6 years
t=6
given
I=8925
P=35000
R=r
T=6
8925=35000*r*6
8925=210000*r
divide both sides by 210000
0.0425=r
the interest rate is 4.25%

Hello. Would love to try and help, your screenshot is not showing up when I click on it though.
Answer:
(- 3, 37) and (-
,
)
Step-by-step explanation:
Given the 2 equations
2x² - y + 19 = 0 → (1)
y + 11x = 4 → (2) ← subtract 11x from both sides
y = 4 - 11x → (3)
Substitute y = 4 - 11x into (1)
2x² - (4 - 11x) + 19 = 0
2x² - 4 + 11x + 19 = 0
2x² + 11x + 15 = 0 ← in standard form
(2x + 5)(x + 3) = 0 ← in factored form
Equate each factor to zero and solve for x
2x + 5 = 0 ⇒ 2x = - 5 ⇒ x = - 
x + 3 = 0 ⇒ x = - 3
Substitute these values into (3) for corresponding values of y
x = -
: y = 4 +
=
⇒ (-
,
)
x = - 3 : y = 4 + 33 = 37 ⇒ (- 3, 37 )
