multiply all terms in the second equation by 2 to get the coefficient on the y variable to be -6.
Answer:
d
Step-by-step explanation:
Step-by-step explanation:
Against the wind, the wind works against the speed. With the wind, the wind aids the speed.
4(p - w) = 2416
4(p + w) = 2896
p - w = 604
p + w = 724
2p = 1328
p = 664 mph
664 + w = 724
w = 60 mph
<u>Answer-</u>
<em>Maria's monthly payment will be </em><em>$376.91</em><em> </em>
<u>Solution-</u>
Maria is buying a car worth of $18,510, but she will finance only $13,000 of it with a 3-year loan at 2.8% APR.
We know that,
![\text{PV of annuity}=P[\dfrac{1-(1+r)^{-n}}{r}]](https://tex.z-dn.net/?f=%5Ctext%7BPV%20of%20annuity%7D%3DP%5B%5Cdfrac%7B1-%281%2Br%29%5E%7B-n%7D%7D%7Br%7D%5D)
Here,
Putting the values,
![\Rightarrow 13000=P[\dfrac{1-(1+\frac{2.8}{1200})^{-36}}{\frac{2.8}{1200}}]](https://tex.z-dn.net/?f=%5CRightarrow%2013000%3DP%5B%5Cdfrac%7B1-%281%2B%5Cfrac%7B2.8%7D%7B1200%7D%29%5E%7B-36%7D%7D%7B%5Cfrac%7B2.8%7D%7B1200%7D%7D%5D)
Therefore, her monthly payment will be $376.91

value of the determinant of a 2x2 matrix is the product of the top-left
and bottom-right terms minus the product of the top-right and
bottom-left terms.
The value of the determinant of a 2x2 matrix is the product of the top-left and bottom-right terms minus the product of the top-right and bottom-left terms.
= [ (1)(-3)] - [ (7)(0) ]
= -3 - 0
= -3
Therefore, the determinant is -3.
Hope this helps!</span>
