X + 4y = -9 . . . (1)
2x + 5y = -6 . . . (2)
From (1): x = -9 - 4y . . . (3)
Substituting (3) into (2) gives, 2(-9 - 4y) + 5y = -6
-18 - 8y + 5y = -6
Required equation is -18 - 3y = -6
Answer:
You could approximate pi to be 3.14, and divide that by 6.
Step-by-step explanation:
Answer:
D. 3 quarters and 17 dimes
Step-by-step explanation:
1 quarter = $0.25
1 dime = $0.10
0.25 × 3 = $0.75
0.10 × 17 = $1.70
1.70 + 0.75 = $2.45
0.25(3) + 0.10(17) = $2.45

The value of the function f(x)=6/-2+2 at x=4 after rounded to the nearest tenth is -2.4.
Given Function of x : f(x)=6/-2+2
The given function showing the relationship between x and f(x) is f(x)=6/-2+2 where e is exponential and we have to find the value of f(4) by just putting the value of x=4 in the given function and round to the nearest tenth means replacing a number with an approximate value.
f(4)=6/-2+2 ( The value of e is 2.7812)
f(4)=-3+2
f(4)=-3+2*0.30119 (The value of is 0.30119)
f(4)=-3+0.60238
f(4)=-2.3972
Round -2.3972 to tenth is -2.4.
Hence the value of function of at x=4 is -2.4.
