There is no graph, so it is impossible to answer this question. I apologise.
Answer:
Step-by-step explanation:
they have given you three points P1 , P2 and P3. We only need two of them, any two will work
P1= (x1, y1) = (-1,8)
P2=(x2,y2) = (3,-4)
now use the slope formula to find the slope , use the variable 'm' for slope since that a very commonly used variable letter for slope
m = ( y2 - y1 ) / ( x2 - x1 )
m = (-4 - 8 ) / ( 3 - (-1) )
m = (-12) / 3 + 1 )
m = -12 / 4
m = - 3
there is your slope, got it? send a note if you have other questions :)
90 + 2x + 104= 360,
360-194 = 2x
166 = 2x, x =83.
X+67 = 150, X+37= 120.
-> 150, 120
Good evening!
We can solve this problem noting that we have a right-angled triangle. You can see in the attachment a draft of the problem.
We want to discover the angle
θ.
Note that the
tangent of the angle gives a information about this angle.
tangent = opposite / adjacent
Answer:
Step-by-step explanation:
we know that
The roots of the quadratic function (x-intercepts) are
x=-1 and x=5/3
so
we can write the equation of the parabola as
where
a is a coefficient
Remember that
The parabola pass through the point (5,40)
substitute the value of x and the value of y of the ordered pair in the quadratic equation and solve for a
x=5, y=40
substitute
apply distributive property
see the attached figure to better understand the problem
