A function f is defined by f(x)=3x+19. If x increases by 2, by how much does f(x) increase?

1 answer:

7 0

The slope of the function is given by the coefficient of x (here it is 3)

so as x increases by 2 f(x) will increase by 3*2 = 6

Answer is 6.

Given a slope and a point write a perpendicular equation in standard form.

Hi there! The answer would be:

y=-2/5x+2.

Explanation:
We can start by plotting the given point (-5,3). From there, we can use the slope to place other points to find the y intercept. Using the slope of the graph, we can find that the line segment hits (2,0). Therefore, how answer would be: y=-2/5x+2

Hope this helps!!! :DD

The school band is ordering health bars to sell for a fundraiser. The company that sells the bars charges $0.40 per bar plus $20

Fofino [41]

Step-by-step explanation:

just think it through :

0.4x + 20 < 200

0.4x < 180

x < 180/0.4 = 450

so, x < 450

they must order less than 450 bars.

therefore, the first answer option is correct :

they can order from 0 to 449 bars, but no more.
