X² - 17x + 30 = 0
x² - 15x - 2x + 30 = 0
x(x-15)-2(x-15)=0
(x-2)(x-15)=0
x=2, x=15
The answer is one because 3-2 =1 I hope it helps
Answer:
The diameter of the circle is 24.9 in
Step-by-step explanation:
To solve this exercise we need to use the circumference formula of a circle and clear d:
c = circumference = 78.1 in
d = diameter
π = 3.14
c = π * d
d = c / π
we replace the known values
d = 78.1 in / 3.14
d = 24.8726 in
round to the nearest tenth
d = 24.8726 in = 24.9 in
The diameter of the circle is 24.9 in
A. slope is rise/run. can count up 3 right 2. slope = 3/2
also by slope formula m = (y - y1)/(x - x1)
B. y-intercept is the y coordinate where the line crosses the y-axis.
See that it is at y = -4 on the graph?
To use the slope.. go backwards from the closest point (4,2) down 2 left 3 gets you to the next point (2,-1) then go down 2 left 3 again to get to y-intercept (0, -4)
C. y = (3/2)x - 4
How you get it is by putting in the values into the standard equation for a line; y = mx + b
m is slope and b is y-intercept.
