Given f(x) = x - 10. What is f(-7) ?

Answers

f(x) = x-10

f(-7) = -7 -10

f(-7)= -17


I understand now !
f(x)= x - 10

f(-7) = - 7 - 10

f(-7) = - 17

3 divided by what equals 94

Answers

282 because if u multipy 94 into 3 u get 282 and to check 282 divided by 3 is 94
3/x=94
3=94x
x=3/94

Dividing 3 by 3/94 equals 94:

(3)/( (3)/(94) ) =3* (94)/(3)=94 

24x + 34p = p
Solve for p

Answers

Answer:

(-24)/(33) x = p

Step-by-step explanation:

24x + 34p = p  Subtract 34 p from both sides of the equation

24x + 34p -34p = p - 34p

24x = -33p  Divide both sides by -33

(24x)/(-33) = (-33p)/(-33)

(24x)/(-33) = p or .2727...

If f(x) = 2x + 3 and g(x) = (x - 3)/2, what is the value of f[g(-5)]?

Answers

If f(x) = 2x + 3 and g(x) = (x - 3)/2,what is the value of f[g(-5)]?f[g(-5)] means substitute -5 for x in the right side of g(x),simplify, then substitute what you get for x in the rightside of f(x), then simplify.It's a "double substitution".To find f[g(-5)], work it from the inside out.In f[g(-5)], do only the inside part first.In this case the inside part if the red part g(-5)g(-5) means to substitute -5 for x ing(x) = (x - 3)/2So we take out the x's and we haveg( ) = ( - 3)/2Now we put -5's where we took out the x's, and we nowhaveg(-5) = (-5 - 3)/2Then we simplify:g(-5) = (-8)/2g(-5) = -4Now we have the g(-5)]f[g(-5)]means to substitute g(-5) for x inf[x] = 2x + 3So we take out the x's and we havef[ ] = 2[ ] + 3Now we put g(-5)'s where we took out the x's, and wenow havef[g(-5)] = 2[g(-5)] + 3But we have now found that g(-5) = -4, we can putthat in place of the g(-5)'s and we getf[g(-5)] = f[-4]But thenf(-4) means to substitute -4 for x inf(x) = 2x + 3sof(-4) = 2(-4) + 3then we simplifyf(-4) = -8 + 3f(-4) = -5Sof[g(-5)] = f(-4) = -5
