How to solve using substitution

Mathematics
1 answer:
DiKsa [7]3 years ago
4 0
X+5 = x^2 - x + 2
0 = x^2 -2x - 3
0 = (x-3)(x+1)

x = -1,3

y = -1 + 5 OR y = 3+5
y = 4 OR y = 8

y = 4,8

So we have two ordered pairs, (-1,4) and (3,8).

Hope that helped!

can you mark my answer as brainliest btw?

F(x) = 1/x^2 and g(x) = 1/2x+4<br><br> f[g(x)] = 4x 2 _____
Korolek [52]

Answer:

f[g(x)] = 4x²+1/16

Step-by-step explanation:

We need to put g(x) into f(x).

f[g(x)] = 1/(1/2x+4)²

f[g(x)] = 1/(1/4x²+16) Solve the exponential.

f[g(x)] = 1/(1/4x²+16) Simply the fraction.

f[g(x)] = 4x²+1/16

babunello [35]

Answer:

B.  x ≤ 2.

Step-by-step explanation:

56 - 10x ≥ 20 + 8x

-18x ≥ -36

x ≤ -36/-18 = 2.      ( Note that the inequality sign flips because we are dividing by a negative value).

The velocity V of an object dropped from a tall building is given by V = V64d, where dis
ozzi

Answer:

d = 0.0625 m

Step-by-step explanation:

The velocity of an object dropped from a tall building is given by :

v=\sqrt{64d}

Where

d is the distance in feet

We need to find the distance when the velocity is 32 ft/s

Rearranging for d,

v^2=64d\\\\d=\dfrac{64}{v^2}

Put v = 32 ft/s

d=\dfrac{64}{32^2}\\\\d=0.0625\ m

So, the required distance is 0.0625 m.
