In this question, we can expend the formula and rearrange it.
You can try it first, and the steps are as follow:
Step 1: Expend it

As there are fraction in the formula and it doesn't look good, we can eliminate it by multiplyng 3.
Step 2: Multiply by 3

Step 3: Rearrange the terms

Answer:
g(x)=5x+7
Step-by-step explanation:
f(x)+g(x)=9x+4
We are given f(x)=4x-3.
So we insert 4x-3 for f:
4x-3+g(x)=9x+4
Subtract 4x on both sides:
-3+g(x)=5x+4
Add 3 on both sides:
g(x)=5x+7
Check:
f(x)+g(x)
=(4x-3)+(5x+7)
=(4x+5x)+(-3+7)
=(9x) +(4)
=9x+4
Bingo. We did it! :)
Answer:
James = £60, Ryan = £40 and Jill = £20
Step-by-step explanation:
James - 3, Ryan - 2 and Jill - 1
3 + 2 + 1 = 6
£120 / 6 = 20
Times 20 by each of the three numbers (3, 2 and 1)
3 x 20 = £60 (James)
2 x 20 = £40 (Ryan)
1 x 20 = £20 (Jill)
Howdy there! :D The answer to your question is True because reciprocal means the denominator and numerator and flipped like 2/4 and 4/2.
Hope I helped! ;)
Sendo A = (-1, 0, 1, 2) e B = (-2, -1, 0, 1, 2, 3, 4), verifique em cada caso se a lei dada define uma função de A com valores e
