Answer:
The equation of line with slope -7 passing through (5,9) in point-slope form is:
Step-by-step explanation:
Given
Slope of line = m = -7
Point = (5,9)
The point slope form of equation is obtained from a point and slope. It is given by the equation:
We know that (x1,y1) = (5,9)
Putting the values we get
Hence,
The equation of line with slope -7 passing through (5,9) in point-slope form is:
Answer:
f(x)= -3x² - 12x - 5
Step-by-step explanation:
-3(x+2)² + 7
-3(x+2)(x+2) + 7
(-3x-6)(x+2) + 7
-3x² - 6x - 6x - 12 + 7
-3x² - 12x - 5

Answer:
2 intersections
Step-by-step explanation:
The greatest possible number of intersections of these graphs is 2 intersections. This is because a quadratic equation always appears on a graph as a parabola, either facing up or down. a Linear expression is a straight line, when placed in the same graph as a parabola only three things can happen. It can completely miss the parabola. It can pass through only one half of the parabola (thus intersecting at one point only), or lastly it can go through both halves of the parabola (intersecting at 2 points) as shown in the picture below.
Cost of hosting the tournament : $1,000
If it rains, the club will lose the investment: $ -1,000
If it is sunny, the club will collect $4,500 ; profit: 4,500 - 1000 = 3,500
chance of rain is 20%
-1,000 * 20% = -200
3,500 * 80% = 2,800
2,800 - 200 = 2,600 Choice C.
