Answer:
Using y = mx + c
slope = -17+5/3-1 = -12/2 = -6
Using point (1 , - 5)
y + 5 = -6(x - 1)
y + 5 = - 6x + 6
y = - 6x + 6 - 5
y = - 6x + 1
Hope this helps.
Answer:
y=3/4x-2.5
Step-by-step explanation:
This is a straight line, so it would follow the equation y=mx+b. You can find the b value by looking at the y-intercept of the equation (where x=0), which in this case would be -2.5. Then, you can find the m value by comparing the two given points' locations. Slope is rise over run, so first you can find the rise. The y value moves from y=-4 to y=2, which is a value of 6 units upward. The points move from x=-2 to x=6, which is a distance of 8 units. Finally, put it into the rise over run pattern, giving you 6/8, which simplified is 3/4. This is your m value. Finally, plug in your two variable values into y=mx+b and you'll get y=3/4x-2.5.
Answer:
back where he started
Step-by-step explanation:
First he went up 30 feet.
Then he went -30 feet.
Meaning that he went up the went back down.
Which is basically 30-30
I think that should be right.
Answer:
P(x) = -1.6x + 52
Step-by-step explanation:
Let 2000 as the start point, so it will be the year 0, x = 0, and the population that uses newspaper (y) will be y = 52%. The slope of a linear function is how much it increases or decreases, so the slope is -1.6 (the minus signal indicates that it's decreasing). The slope can also be calculated by the equation:
a = Δy/Δx, where a is the slope, and Δy and Δx are the difference between two points in the function.
So, for x years, the population percentage will be y:
-1.6 = (y - 52)/(x - 0)
-1.6x = y - 52
y = -1.6x + 52
P(x) = y
P(x) = -1.6x + 52
Answer:
The measure of radius c is 12.36 cm
C is correct.
Step-by-step explanation:
Given: A regular pentagon is shown in diagram.
As we know the sum of angle of pentagon is 540°
It is a regular pentagon. Therefore, each angle is equal.
OB would be angle bisector of angle B
Thus,
In triangle OBC, ∠C=90°
Hence, The measure of radius c is 12.36 cm
