Start at negative 5 since that’s your y-intercept.
Since 3/5 is your slope and slope equals rise over run you go up 3 units and go right 5 units.
X=4
I'm gonna show you the step by step process
0.5*4=2
2-6=-4
and that is why x=4
Hey there!
When we say (f + g)(2), we are adding both functions together and plugging in 2 for x.
Since f(x) is equal to 2x + 210 and g(x) is equal to 2x + 125, (f + g)(x) is equal to (2x + 210) + (2x + 125).
That can be simplified to 4x + 335.
So, (f + g)(x) = 4x + 335.
Let's plug 2 in for x and solve.
(f + g)(2) = 4(2) + 335
Multiply.
(f + g)(2) = 8 + 335
Add.
(f + g)(2) = 343
The x value is consistent for the values of both equations, in both x is defined as the number of hours spent exercising.
So, (f + g)(2), which is 343, is the amount of calories burned and the calorie deficit on a diet when 2 hours are spent exercising.
Hope this helps!
X² + 6x + ____ - (y² + 4y + ____ ) = -4 + ____ + ____
x² + 6x + 9 - (y² + 4y + 4 ) = -4 + 9 + -4
(x + 3)² - (y + 2)² = 1
