Answer:
x=1/3
y=-7
Step-by-step explanation:
using the elimination method, you can add both equations vertically, to eliminate the x
-3x+y=-8
3x+2y=-13
3y=-21
y=-7
we then fix the value of y into the first equation
-3x+y=-8
-3x-7=-8
-3x=-8+7
-3x=-1
x=1/3
A.) -11
b.) 31
c.) -208
d.) 12
e.) -47
f.) -28
I hope this helped (I used bedmas)
Answer:
$2355.06
Step-by-step explanation:
Use the compound interest formula, filling in the numbers you know. Then solve for the number you don't know.
A = P(1 +r/n)^(nt)
where A is the account balance, P is the amount invested, r is the annual rate, n is the number of times per year interest is compounded, and t is the number of years.
Filling in the given values, we have ...
4000 = P(1 +.053/52)^(52·10) = P(1.6984738)
P = 4000/1.6984738 ≈ 2355.06
You would need to deposit $2355.06 in order to have $4000 in 10 years.
Answer:
80°
Step-by-step explanation:
<u>The angles of a triangle must add up to 180°.</u>
40° + 60° + missing angle = 180°
100° + missing angle = 180°
<em>subtract 100° from both sides</em>
missing angle = 80°
YES if you simplify 15:10 by 5 since they can both be divided by 5 the ratio becomes 3:2
