Answer:

y= -2x+18

Step-by-step explanation:

1. The secant line is a line that passes through 2 points in the function.

2. Determine the y values for x=-6 and x=3 by plugging the x values into the x^2 + x function. This yields 30 for x=-6 and 12 for x=3.

3. Find the slope by calculating the rise over the run, represented by the equation (y2 - y1)/(x2-x1). Plugging in the numbers we get (12-30) divided by (3 -(-6)). This gives you a slope equation of -18/9 (subtracting a negative yields a positive), which simplifies to -2.

4. Now that you have your slope m, apply it backwards from x=3 (x=2 yields 14 for y, 1 yields 16, 0 yields 18). Once you arrive at x=0, the y value is your y-intercept.

5. Put the y-intercept b into the equation y= mx+b, and you come out with y= -2x + 18!

A tetrahedron is a triangular pyramid whose four faces are identical equilateral triangles. The total lateral surface area is 93
Westkost [7]

Answer:

SA = 124 cm²

Step-by-step explanation:

The lateral surface area is the area of all sides besides that base, so 93 cm² is the sum of 3 sides of the tetrahedron.  

93/3 = 31 cm² per side, there are 4 sides, so 31(4) = 123 cm² is the total surface area

Three single-digit numbers multiply to make 504 Write the missing numbers
boyakko [2]
We will guess and check to solve this problem

504/9= 56
504/8= 63
504/7= 72
504/6= 84
.....
we can continue the pattern. However, we know that 50 is the product of 8 and 7, so we can use that number

9*8*7=504
