Answer:
110 degrees
Step-by-step explanation:
to find the angle x, we need to use the formula to find the 50 degree angle:
(y - x) / 2 = 50
y is 210
(210 - x) /2 = 50
210-x = 100
x = 110 degrees
I believe the answer is c there is no x value as there is no solution
Answer:
Step-by-step explanation:
Equation of a line giving 2 points is
y-y1=m(x-x1) where m is the slope and (x1,y1) is one of the points.
First we have to find the slope using formula
(y2-y1)/(x2-x1) where (x1,y1) and (x2,y2) are the points given
Slope m is (4-13)/(8--4) =-9/12 = -3/4
Looking at the answer choices, the only slope intercept equation that use the slope -3/4 is answer choice A
It’s either b or c the hypotenuse is always the longest side
The vertex is at (0, 3) so y=a(x-0)²+3, which is y=ax²+3
next, use a given point to find a: 10=a(3)²+3, so 9a=7, a=7/9
the equation is then y=
as for the first question, the shape is an ellipse, the domain is -5≤x≤5, the range is -3≤y≤3
the equation can be written as :
