Notice that the function has negative values between week zero and week 5; thus, just after week 5, the group earned a profit (since the graph reaches positive values just after week 5).

<h2>The answer is 5 weeks. That information is located at the x-intercept different than x=0.</h2>

Jaymile wants to construct congruent angles with a compass and straightedge, while Annie wants to construct congruent segments w
andre [41]

Answer: See below

Step-by-step explanation:

  • Both will use the straight edge to make segments and use the compass to take measurements.
  • They will draw a line with a straight edge and will find a starting point, then with a compass:
  • Annie will take the measurement of the segment and, from the starting point of the line, will put in the other point to obtain the congruent segment.
  • But in Jaymie's case, she will need to do a little more work with a compass because to build congruent angles, she will need to make a semi-circle in the original angle and transfer this measurement to the new line to construct the angle.

Write the rule for the linear function. Remember a function rule is written using f(x)
Marina CMI [18]

Answer:

The rule for the linear function will be:

f(x) = -2x+5

Step-by-step explanation:

We know that linear function can be represented using the slope-intercept formula

y = mx+b

where m is the slope and b is the y-intercept

Given the function is linear

Taking two points from the table to determine the slope

  • (1, 3)
  • (2, 1)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(1,\:3\right),\:\left(x_2,\:y_2\right)=\left(2,\:1\right)

m=\frac{1-3}{2-1}

m=-2

Using the point-slope form of the line equation

y-y_1=m\left(x-x_1\right)

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = -2 and the point (1, 3)

y-y_1=m\left(x-x_1\right)

y - 3 = -2 (x-1)

y-3 = -2x+2

adding 3 to both sides

y-3+3 = -2x+2+3

y = -2x+5

or

f(x) = -2x+5

Therefore, the rule for the linear function will be:

f(x) = -2x+5
