Whats the equation i dont think i can solve with out an equation
Answer:
B
C
A
Step-by-step explanation:
Find the value of x in each equation then compare the solutions from the least to the greatest
<u>In A</u>
5( x-6)+3x=3/4(2x-8) ------------Open brackets
5x-30+3x=3/2x-6
5x+3x-30=3/2x-6
8x-3/2x=-6+30---------------collect like terms
16x-3x=48
13x=48-----------------dived both sides by 13
x=48/13 = 3.7
<u>In B</u>
2.7(5.1x+4.9)=3.2+28.9-------------open bracket
13.77x+13.23=32.1
13.77x=32.1-13.23---------------collect like terms
13.77x=18.87
x=18.87/13.77----------------------divide both sides by 13.77
x=1.37
<u>In C</u>
5(11x-18)=3(2x+7)--------------------open brackets
55x-90=6x+21
55x-6x=21+90-----------------------collect like terms
49x=111----------------------------------divide both sides by 49 to get x
x=111/49 = 2.27
From the solutions, the least value of x is in B, then C ,and finally A
Answer:
2/15
Step-by-step explanation:
2/3 divided 5 is really just:
2/3*1/5
that is just 2/15!
Answer:
f(x) = 4x³+16x²+4x-24
Step-by-step explanation:
Factors are (x+3)(x+2)(x-1)
(x+3)(x²+2x-x-2)
(x+3)(x²+x-2)
x³+x²-2x+3x²+3x-6
x³+4x²+x-6
This could have been the function but the intetcept is 6 here.
So we'll take a miltiple of this one such that the intercept becomes-24
-24/-6 = 4
That multiple is 4
f(x) = 4(x³+4x²+x-6)
f(x) = 4x³+16x²+4x-24
