Answer:
TUA=123
Step-by-step explanation:
so first we find <TUS in terms of x
so 180-11x-2
178-11x
so now we can use the sum of a triangle's angles which is always 180 to find the angles in triangle TUS
178-11x+5x+10+58=180
178-6x=112
take 178 from both sides
-6x=-66
x=11
so we can do 11x11+2=TUA
TUA=123
I don’t know find it out lol
-4 is the answer to the Questor
Step-by-step explanation:
Ok, so first...
a) if x is positive, it will remain x, so *x<7*
b) if x+3 is positive, it will be x+3<9 but you have to simplify it so you subtract 3 on both sides and get *x<6*
c) if y-8 is positive, it will stay like that, and you then add 8 on both sides to get *y>19*
g) if 3x-1 is positive, it will be 3x-1 greater than or equal to 18. add 1 on both sides and *3x > or = to 18*
4y+3 < or = 13. subtract 3 on both sides and you get *4y < or = 13*
One more thing:
Less than or equal to is a '<' with a line underneath.
Greater than or equal to is a '>' with a line underneath.
V=(-5,-4)
to find the vertex you use V=-b/2a
y=-3(x+5)^2-4
which then turns to
y=-3x^2-30x-79
a=-3
b=-30 x=30/2(-3)
x=30/-6
x=-5
plug x into the equation and solve for y =-3(-5)^2-30(-5)-79
y=-4
x=-5 y=-4 Vertex=(-5,-4)
