If x= 5 and y = 2, work out the value of a) 3x + y<br> b) 2x2<br> c) (x - y)2
Oxana [17]

Answer:

17, 50, 9

Step-by-step explanation:

Hello

We already know the values of x and y, 5 and 2.

All we have to do to figure out a, b, and c, is to plug in those known values.

a) 3x + y

Let's plug in x and y as 5 and 2

3(5) + 2

15 + 2

17

b) 2x^2

2(5)^2

2(25)

50

c) (x - y)^2

(5 - 2)^2

3^2

Let f(x)=x-3 and g(x)= x^2-x. Find and simplify the expression. (f+g)(2)
ValentinkaMS [17]

Answer:

<h2>(f+g)(2) = 1</h2>

Step-by-step explanation:

Given :

f(x) = x − 3

g(x) = x² − x

Note : (f+g)(x) = f(x) + g(x)

then

(f+g)(2) = f(2) + g(2)

           = (2 - 3) + (2² - 2)

           = -1  +  2

           = 1

another method:

(f+g)(x) = f(x) + g(x) =  x − 3 + x² − x = x² - 3

then

(f+g)(2) = 2² - 3 = 4 - 3 = 1

M&lt;6=(5x+99)* and m&lt;10=(3x+17)* find m&lt;10
Ann [662]
Sorry, but it does not make sense to start with m<0 and then connect that with an "=" sign to (3x+17).  Please ensure that you have shared the entire problem.  

You write "m<10=(3x+17)*   but provide no info regarding the value of x.

Please start over.
