-15+11=-4 so Maggie has -4 in her account
Answer:
4.7
Step-by-step explanation:
If you use the rules of the signs to eliminate the minuses and then substract 8.1 from 3.4 you get 4.7 which, if you sum it with 3.4 gives 8.1
Answer:
See below.
Step-by-step explanation:
Substitute the value for the variable and solve.
a.)
⇒ y = -5(3) + 17
⇒ y = -15 + 17
⇒ y = 2
b.)
⇒ y = 3(3) - 22
⇒ y = 9 - 22
⇒ y = -13
c.)
⇒ y = 2(3) - 25
⇒ y = 6 - 25
⇒ y = -19
d.)
⇒ y = 6(3) - 39
⇒ y = 18 - 39
⇒ y = -21

Apply the Keep Flip Change rule here
1/4 has been kept the same
The sign has been changed
The other fraction needs to be flipped
Thus, z = -2/7

Answer:
4 lines of reflection can the combined figure reflect onto itself.
Step-by-step explanation:
Given Square ABCD and square EFGH share a common center on a coordinate plane and is parallel to diagonal.
We have to find that how many lines of reflection can the combined figure reflect onto itself.
Line of reflection is the line through which the figure will reflect to give a mirror image i.e the midway line between the pre-image and its image reflection. In the figure drawn in attachment according to given question we see that the line passes through the center of one square which is the diagonals of other square reflect the given figure onto itself.
Hence, there are 4 lines of reflection i.e 4 lines of reflection can the combined figure reflect onto itself.
