<span>Multiply equation(2) with 4 so that coefficient of become same in both the equations(You can make coefficient of y same and can follow the following procedure.)
</span><span>* Subtract (3) from (1)
* </span>Divide both sides by -19
*Subtract 21 from both sides.
*Divide both sides by 4
so the solution is x= 3 and y= -7
Hope I helped you :)
Answer:
82.56 cm squared
Step-by-step explanation:
12.9-8.6
4.3
4.3*6.4
27.52- area of the triangle on the left of the figure.
Then figure out the rectangle that completes the figure.
8.6*6.4
55.04
Add the two values to complete the figure:
55.04+27.52
82.56 cm squared should be correct.
Have an amazing day!!!

T= total length
T=1 2/5 meters + 4 1/5 meters
add the whole #s and the fractions
T= (1+4) + (2/5 + 1/5)
T= 5 3/5 meters total
Hope this helps! :)
Answer:
b=4
Step-by-step explanation:
g(x)=x^2+bx+11
When x = -1 g(x) = 8
8 = (-1)^2 +b(-1) +11
8 = 1 -b+11
Combine terms
8 = 12-b
Subtract 12 from each side
8-12 = 12-b-12
-4 = -b
Multiply by -1
4 = b
Present value, PV = $500
Future value, FV = 2*PV = 2*500 = $1,000
Rate, r = 4% = 0.04
Compounding times in a year, n = 4 (compounded quarterly)
Time, t = ??
The future value expression is stated as:
FV = PV (1+r/n)^nt
Substituting;
1000 = 500 (1+0.04/4)^4t
2 = (1.01)^4t
ln 2 = 4t ln 1.01
0.6931 = 4t* 0.00995
0.6931 = 0.0398t
t = 17.414 years
Time required for the amount to double is 17.41 years.
