Answer:

x=-9

Step-by-step explanation:

first you make the coefficients equal to each other by doing a common factor which in this case is 5. Then you have to do the variable for each time the common number is repeated which is 5^x * 5^x= 5^(x+3)*5^(x+3)*5^(x+3) This would make it equal to 5^2x=5^(3x+9). Since the non exponents are common factors you can get rid of them and solve for the exponent by doing 2x=3x+9. You solve that equation to get x=-9.

F(x)=5 g(x)=sqrt x+2 find: (f-g)(x) (f • g(x) (f/g)(x) (f o g)(x)

Sergeeva-Olga [200]

f(x) = 5

g(x) = $\sqrt{x + 2}$

(f-g)(x) = 5 - $\sqrt{x + 2}$

(f * g)(x) = 5 $(\sqrt{x + 2})$ = $5\sqrt{x + 2}$

(f/g)(x) = $\frac{5}{\sqrt{x + 2}}$ = $\frac{5\sqrt{x + 2}}{{x + 2}}$

f(g(x)) = 5

What is the perimeter of the triangle. Please look at photo. I need you help. Thank you in advance♡

bulgar [2K]

Answer : 12.9 units

explanation :

Sides: a = 7.616 b = 7.211 c = 13.038

Area: T = 23
Perimeter: p = 27.865
Semiperimeter: s = 13.933

Angle ∠ A = α = 29.291° = 29°17'29″ = 0.511 rad
Angle ∠ B = β = 27.597° = 27°35'50″ = 0.482 rad
Angle ∠ C = γ = 123.111° = 123°6'41″ = 2.149 rad

Height: ha = 6.04
Height: hb = 6.379
Height: hc = 3.528

Median: ma = 9.823
Median: mb = 10.05
Median: mc = 3.536

Inradius: r = 1.651
Circumradius: R = 7.783

Vertex coordinates: A[3; -1] B[16; -2] C[9; -5]
Centroid: CG[9.333; -2.667]
Coordinates of the circumscribed circle: U[0; 0]
Coordinates of the inscribed circle: I[3.158; 1.651]

Exterior (or external, outer) angles of the triangle:
∠ A' = α' = 150.709° = 150°42'31″ = 0.511 rad
∠ B' = β' = 152.403° = 152°24'10″ = 0.482 rad
∠ C' = γ' = 56.889° = 56°53'19″ = 2.149 rad

(Y-2,2x+1)=(x-1,y+2)

Alex

Answer:

x=2 and y=3

Step-by-step explanation:

y-2=x-1

or,x-y=-1.......(1)

again,

2x+1=y+2

or,2x-y=1.......(2)

now,

solving equations (1)&(2),we get,

x=2 and y=3
