Answer:
x = -1, 3
Step-by-step explanation:
so what you need to do is graph each one because that's what the questions ask. One way for you to check your answer is to set the two equations equal to each other.
-x + 5 = x^2 - 3x + 2
you want to end up with one equation and having the equation equal 0. So add x to both sides to cancel out the x on the left side and then subtract 5 from both sides to cancel out the 5 on the left side.
0 = x^2 - 2x - 3
now you factor
0 = (x - 3) (x + 1)
x = -1, 3

Answer:
It is probably equal to 100 degrees, but you have not given the context of the problem.
Answer:
should u add or multiply it
Answer:
10. Let m<Y = y.
Then,
m<Y + m<X +m<Z = 180 [ Sum of angles of triangle is 180 degrees]
or, y + (6x-23) + (4x + 9) = 180
or, y + 10x -14 = 180
or, y = 194 - 10x
or, m<Y = 194 - 10x
12. Solution,
a. m<1 = 60 degrees [Each angles of equilateral triangle is equal to 60 degrees]
b. In triangle WYZ,
m<Z + m<ZWY + m<ZYW =180 [Sum of angles of triangle is 180]
or, 138 + m<ZWY +m<ZWY =180 [Base angles of isosceles triangle are equal, i.e. m<ZYW = m <ZWY]
or, 2 (m<ZWY) = 180 -138 = 42
or, m<ZWY = 21 = m<ZYW
or, m<3 = 21 = m<5
c. Solution,
m<XWY = m<2 + m<3 [Addition axiom]
or, 60 = m<2 + 21 [Each angle of equilateral triangle is 60]
or, m<2 = 39
d. Solution,
m<4 + m<5 =60 [<XYW = 60 ]
or, m<4 + 21 = 60
or, m<4 = 39
