A is 7 & 7/8. B is correct. C is 1 & 1/4. They are all in simplest form, also.
Answer:
What do the x-intercepts and maximum value of the graph represent? The x-intercepts represent the points at the ground, so with that you have the width of the tunnel at ground level is 120 ft - 0 ft = 120
Step-by-step explanation:
Parallel lines have equal slopes. so the equation y=-4x+5.has slope of -4 because this is in slope intercept form y=mx+b where m is slope.
so we know a parallel line will have slope -4
we have a point on the line so we will use point slope formula to solve.
y-y1=m(x-x1) where (x1,y1) is point on line
so we get
y-4=-4(x-0) to put in slope intercept form we solve for y
y-4=-4x
y=-4x+4 is an equation of a line parallel to y=-4+5 passing through (0,4)
Answer:
A. Center (4,3); Radius = 5 units
Step-by-step explanation:
The equation of a circle can be written in the form
(x-h)^2 + (y - k)^2 = r^2
where (h,k) is the center and r is the radius
(x-4)^2 + (y - 3)^2 = 25
(x-4)^2 + (y - 3)^2 = 5^2
The center is (4,3) and the radius is 5
