F(x)=9-2x move negative two over to f(x) and combine the two so it then becomes 3x then combine 9 and 25 and you get 34 then subtract f(x)to 3x and you get 2x and then divide 34 by 2x and you get 17

Answer:

x = -8

Step-by-step explanation:

Set the function f(x)=9-2x equal to 25, and then solve the resulting equation for x:

9 - 2x = 25.

Isolate the -2x term by subracting 9 from both sides:

-2x = 16

Finally, solve for x by dividing both sides by -2:

x = -16/2, or x = -8

brilliants [131]

Answer:

3.50 x+18.00 ≤ 40.00

Step-by-step explanation:

She pays 18 dollars each moth, therefore that quantity won't change, so you will have to add. Each movie that she watches is an additional 3.50, then we have 3.50 x, x being the quantity of movies that she watches. She can only afford up to 40 dollars, then everything that she spends has to be less or equal to 40.

You are playing in a fantasy football league and Lamar Jackson scored 45 fantasy points. If he keeps his average of 28 fantasy p
jekas [21]

Answer:

213 points

The y-intercept is how many points Jackson already scored, and the slope is how many points he is scoring every game.

Step-by-step explanation:

Jackson earns 28 points per game, so after 6 games, he earns 168 points (just multiply 6 by 28). He already scored 45 points, so if you add them together, he scored a total of 213 points.

The y-intercept is 45, what he already scored, and the slope is 28, how many points he scores per game.

Hope I helped!!!
