Sorry I need a picture to answer sorry :c
Answer:
(0,4)
(2,2)
Step-by-step explanation:
y=x^2-3x+4
x+y=4
the second one can be rewritten as y=4-x
so the system becomes
y=x^2-3x+4
y=4-x
therefore 4-x = x^2-3x+4
that is x^2-2x=0
we can write it as x(x-2)=0 a product is = 0 when one of its factors = 0
so the solutions for x are: x=0 and x-2= 0 that means x=2
to get y you simply use 0 and 2 as value of x for any of the two equations
and you get y=4 and y=2 respectively
Answer:
Step-by-step explanation:
The additive inverse of a number (its "opposite") is what you add to the given number to get a sum of zero.
The correct answer is X = 13! I don’t know how to explain but I am 100% that is the correct answer!
Answer:
Part a): 100 degrees
Part b): Isosceles Triangle
Step-by-step explanation:
Part a): Since the angle measures of all triangles add up to 180 degrees and since the other two angles are 40 degrees, which add up to 80, we can use subtraction to find the answer.
180 - 80 = 100
Part b): Since only two of the three angles in this triangle have the same measure, we can find that it is an isosceles triangle, with base angles measuring 40 degrees, and the vertex angle being 100 degrees.
