Answer:
D
Step-by-step explanation:
-3 1/8 - 2 1/2 is the same as -3 1/2 + -2 1/2
x²-4x-5=0
The given equation is quadratic
So we can perform prime factorisation of it.
factors of -5, that add up to give -4 are -5 and 1
therefore replacing -4x by -5x+x
x²-5x+x-5=0
performing factoring by grouping,
(x²-5x)+(x-5)=0
x(x-5)+(x-5)=0
(x+1)(x-5)=0
x+1=0 and x-5=0
Answer is x=-1 and x=5
Answer:
468.75 Cubic meters
Step-by-step explanation:
15 x 12.5 x 2.5 = volume
187.5 x 2.5 = volume
468.75 = volume
Answer:
1/5
Step-by-step explanation:
2/3 - 7/15
Now when dealing with fractions, alas make the dominator ( bottom number the same), and the rule of thumb is, whatever u do to the bottom, must be done to the top
2 7
-------- - - - - - -
3 15
So now u should think, how to make 3 to 15, so u multiply it by 5, therefore u would also need to multiply it to the top
2 x 5 7
-------- - - - - - -
3 x 5 15
10 7
-------- - - - - - -
15 15
Now just minus horizontally ( u don't need to minus the dominator)
3
---------
15
Now can u make this fraction smaller? As in, is there a number that u can divide to the top and bottom, yes, that number is 3 in this case
3 ÷3
---------
15 ÷3
= 1
- - - - -
5
Thats your final answer
Answer: f(g(x))=-2x+8
*Note: you did not provide answer choices, but this should be the answer.
Step-by-step explanation:
f(g(x)) means you plug in g(x) into f(x).
f(g(x))=-(2x-5)+3
f(g(x))=-2x+5+3
f(g(x))=-2x+8
