The answer is 2.5, but if you say it isn't then maybe it can be as a fraction  \frac{10}{4} or \frac{5}{2}.

Let f(x)=3x+5 and g(x)=x^2.
Nady [450]

Answer:  x² + 3x + 5

<u>Step-by-step explanation:</u>

f(x) = 3x + 5       g(x) = x²

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

             = 3x + 5 + x²

             = x² + 3x + 5

What are the solutions to the following system?<br> -2 x² + y = -5<br> y=-3x²+5
Arturiano [62]

Answer:

x=\pm\sqrt{2}

Step-by-step explanation:

This system of equations is convenient, because the second equation already expresses y in terms of x. Now, you can substitute that in.

-2x^2-3x^2+5=-5

Multiplying both sides by -1 and bringing the 5 over:

2x^2+3x^2-10=0

Combining like terms and factoring out 5:

5(x^2-2)=0

Factoring:

5(x-\sqrt{2})(x+\sqrt{2})=0

Solutions: x=\pm\sqrt{2}

Hope this helps!

I don't understand this question I'm supposed to be graphing
taurus [48]

y≤ 3 when x is 0  and x≤ 3 when y is 0

The graph is attached in figure below

Step-by-step explanation:

We need to graph x+y is equal or less than 3

Writing in mathematical form:

x+y\leq 3

For solving we find x and y intercepts

The y-intercept can be found by putting x=0, y is :

0+y \leq 3\\y\leq 3

y≤ 3 when x is 0

The x-intercept can be found by putting y=0, x is :

x+y \leq 3\\x+0\leq 3\\x\leq 3

x≤ 3 when y is 0

Plotting these values on the graph:

The graph is attached in figure below
