(f+g)(x) is equivalent to f(x) + g(x)
So, you would do (-x^2 +6x-1) + (3x^2 -4x-1)
This is equal to 2x^2 +2x -2

Final answer:
A. (f+g)(x) = 2x^2 +2x -2

Use graphing to find the solution of the system of equations. -x^2+y=1, -x+y=2
vladimir2022 [97]

ANSWER


x=-0.62 or x=1.62




EXPLANATION


For -x^2+y=1



We make y the subject to obtain,



y=x^2+1


We can easily graph this function, because we just have to transform the graph of y=x^2 by shifting the intercept up to 1.



As for the straight line, -x+y=2,


We find the intercepts as follows,



When y=0,x=-2.


When x=0,y=2.


We plot the points (-2,0) and


(0,2).



We now draw the two graphs on the same graph sheet. The intersection of the two graphs gives the solution to be


x=-0.62 or x=1.62


See graph

A positive integer is 11 more than 18 times another. Their product is 6030. Find the two integers.
allsm [11]

Answer:

18 and 335

Step-by-step explanation:

y = 18x + 11

x * y = 6030

x * (18x + 11) = 6030

18x^2 + 11x = 6030

18x^2 + 11x - 6030 = 0

(18x + 335)(x - 18) = 0

18x + 335 = 0                 x - 18 = 0

18x = -335                      x = 18

x = -335/18

x is gonna have to be a positive number...so x = 18

y = 18x + 11

y = 18(18) + 11

y = 324 + 11

y = 335

so ur numbers are 18 and 335

Use the graph or table to write a linear function that relates to y to x. I need help on answering number 8, please and thank yo
siniylev [52]

Answer: y = 2/1 x 0

Step-by-step explanation:

Y=mx+b

2 and 1 are the “rise and run” (m) (from one point to the next, you must go up 2 units then right 1 unit)

The y intercept (b) is the point where it is on the y axis but 0 on the x axis, so 0

The inverse of Fx) is a function.<br> A. True<br> B. False
Misha Larkins [42]

Answer:

true

Step-by-step explanation:

In mathematics, an inverse function (or anti-function) is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g(y) = x.
