Answer:
55
Step-by-step explanation:
35+90=125
180-125=55
The interior angles of a triangle should always add up to 180 degrees
when you multiply a number by 5 and then by 2, it is the same as multiplying by 10. Multiplying by by 10 means you add a zero to the end of the number so the digit in the ones column will always be zero
Answer:
9a + 6b
Step-by-step explanation:
4a+7b+5a-b = 9a + 6b
K, so since directix is below focus, it opens up (2<4)
and directix is y=something so equation is (x-h)^2+4p(y-k) where (h,k) is vertex and p is distance from focus to vertex. if it opens down, p<0, if it opens up, p>0
and the vertex is in the middle of the focus and directix
so
distance bewten (-2,4) and y=2 is 2 units
2/2=1, so 1 unit down from focus
vertex is in the middle so it is at (-2,3)
also, opens up so p=1
vertex (-2,3)
p=1
(x-(-2))^2=4(1)(y-3)
(x+2)^2=4(y-3) is an equation
A) -8.93 > -8.4 is false. There is no solution.
B) -0.7 > -6.12 is true. There are infinite solutions.
C) 7.1 > 7.24 is false. There is no solution.
D) -3.2 > -3.6 is true. There are infinite solutions.
