Shown below

<h2>Explanation:</h2>

The stairway to a cellar has a slope of -4/3, that is:

m=-\frac{4}{3}

On the other hand, the cellar is 2m below the ground. In other words:

y-intercept: \\ \\ b=-2

So this can be modeled by the equation of the line:

y=-\frac{4}{3}x-2

The line has a y-intercept at point (0, -2) and as x increases 3 units y decreases 4 units. So:

x=3 \\ \\ y=-\frac{4}{3}(3)-2=-6 \\ \\ (3,-6) \ is \ also \ a \ point \ on \ the \ line

Finally, let's draw a line that passes through:

(0,-2) \ and \ (3,-6)

By using graphing tool, we get the line shown below.

Lexi made 14 sandwiches for a group picnic. The number of ham sandwiches she made was 4 less than the twice the number of turkey
shutvik [7]

x = # of ham sandwiches

14-x = # of turkey sandwiches ( as Lexi made 14 sandwiches)


as the question said that the number of ha sandwiches are 4 less than twice number of turkey sandwiches,

x = 2 * (14-x) - 4 = 24 - 2x

3x=24

x = 8


the number of ham sandwiches is 8, and the number of turkey sandwiches is 14-8=6

Identify the initial amount a and the growth factor b In the exponential function f(x)=620•7.8x
svetlana [45]
Given:

f(x) = 620e^7.8x

The standard equation for an exponential function is f(x) = Aoe^bx

where Ao is the initial amount
b is the growth factor

so, in this case, the initial amount is 620 and the growth factor is 7.8
