the anwer to 7×3+4×-9×-2= to 93
Answer:
B. 2
Step-by-step explanation:
Assuming the term is meant to look like this: -3x², then the answer is B.2. An exponent is a superscript (super means above, script means writing) that tells you to multiply something by itself.
In this case, -3x² means -3·x·x
If it was written as (-3x)², it would mean (-3x)·(-3x)
Step-by-step explanation:
The vertical angles are congruent. The right angles are congruent. There are 2 angles of a triangle congruent to 2 angles of anther triangle. By AA Similarity the triangles are similar.
Statement A. (vertical angles are congruent)
Statement D. (right angles are congruent)
Triangle AEC is similar to triangle BDC.
Statement E is true but does not help.
Correct statement of proportional side lengths:
BD/AE = CD/CE
x/150 = 200/50
x/150 = 4
x = 600
P.S. I think there is a mistake in the problem. I don't think that statement E is correct. It is a true statement, but it is useless. Statement F is false.
A, C, and E.
you can check them by putting into y=mx+b form. if m is negative then as domain increases range decreases.
