Good evening ,

Answer:

<h2>(f+g)(x) =  x² + 3x - 3.</h2>

Step-by-step explanation:

(f+g)(x) = f(x) + g(x)

           = (3x - 5) + (x² + 2)

           = x² + 3x - 3.

One alloy is 2 parts iron to 3 parts silver and another alloy is 7 parts iron to 3 parts silver. How much of each should be comb
Shalnov [3]
Let x be your first alloy
2/5x+7/10(30-x)=1/2(30)
4x+210-7x=150
3x=60
x=20
So, you need 20 lbs of the first alloy, and 10 parts of the second to make 30 lbs of half iron and half silver alloy!

A spinner is divided into 8 equal sections, and each section contains a number from 1 to 8. What is the probability of the spinn
timurjin [86]

Answer:

B.   1 over 8

Step-by-step explanation:

To determine the probability of the spinner landing on 5, we need to first know what probability is,

probability = required outcome/all possible outcome

since the spinner is divided into 8 equal sections and each section contains number from 1-8, this implies there are total of 64 numbers on the spinner.  This implies that all possible outcome = 64

In each section there is 5, since there are 8 sections on the spinner, the number of 5's on the spinner are 8.

This implies that the required outcome = 8

but

probability = required outcome/all possible outcome

probability (of the spinner landing on 5) = 8/64    =1/8

What is the answer to 5+x=-9
aleksandr82 [10.1K]

5+x=-9

Use the subtractive property of equality to isolate x.

5+x=-9

-5 -5

x=-14

The value that satisfies x is -14. You can check your work by substituting x as -14 and checking if the equation is satisfied.

5+x=-9

x=-14

5+(-14)=-9

5-14=-9

-9=-9

the answer is correct. Succinctly, x=-14.
