<span>If two parallel planes are cut by a third plane, then the lines of intersection are parallel and cannot intersect one another.</span>
Answer:
What question? We need more context
Answer:
The graph in the attached figure
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to

where
a is a coefficient
(h,k) is the vertex
In this problem we have
(h,k)=(1,-4)
substitute

we have
An x-intercept of (-1,0)
substitute and solve for a




The equation is

<u><em>Verify the y-intercept</em></u>
For x=0


The y-intercept is the point (0,-3) -----> is correct
using a graphing tool
see the attached figure
Answer:
The answer is 15 21/40
Step-by-step explanation:
If you convert 8 1/8 to 8 5/40 then convert
7 2/5 to 7 16/40 then add the wholes 7 + 8 = 15
and then add the actual fractions 5/40 + 16/40 = 21/40
then add the whole and the fraction 15 + 21/40 youll end
up with 15 21/40 so that is the awnser PS I’m in 5th grade age 10
Parallel = same slope
Y = 2.4x + b
Plug in the point to find b
1 = 2.4(3) + b
1 = 7.2 + b
b = -6.2
Final equation: y = 2.4x - 6.2
