How would I do this problem. It says to solve and check 5/k? -6?= -3

Answers

Answer 1

Answer: You would first move the 6 onto the other side by adding it. Then you would end up doing -3+6 which is 3. Then your equation will look like: 5/k=3. You would then do opposite operation again to the 5 this time. You do the opposite of dividing, so multiplying. You multiply the 5 on both sides which you would end up doing 5 x 3 which is 15. Your equation will then be looking like k=15. To check if you did it right, just simply plug in the 15 as k. So the equation to check should look like this: 5/15-6=3. Solve it, and you should end up as the answer being equal to 3.

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

Evaluate the expresson when n=8 The product of one fourth and a number increased by 3

Answers

Answer:

Step-by-step explanation:

Substitute the n for 8 in

( $(1)/(4)$ times n)+3

product means multiply, so

( $(1)/(4)$ times 8)+3

First multiply $(1)/(4)$ by 8 to get 2

$(1)/(4)$ · 8 = 2

Then add 2 and 3

2+3=5

I hope this helps :)
