Answer:
B. (8, -54)
Step-by-step explanation:
y = -7x + 2
Check to see if the point makes the equation true
A. (1,2) 2 = -7(1)+2 = -7+2 = 5 False
B. (8, -54) -54 = -7(8)+2 = -56+2 = -54 True
C. (5, -35) -35 = -7(5) +2 = -35+2 = -33 False
D. (1, -7) -7 =-7(1)+2 = --7+2 = -5 False
Answer:
$35,78125
Step-by-step explanation:
8/8 - 3/8 = 5/8
25*5/8 = 15.625
15.625*2.29 = 35.78125
Answer:
B and A
Step-by-step explanation:
the triangles are congruent by AAA
Answer:
-2.7
Step-by-step explanation:
to add a decimal with a negative u must sub react them and If the negative is bigger than the positive than the negative over takes the positive and the awnser is negative.
Since this is a right triangle, we can use our trigonometric functions to solve for x.
Since we know the adjacent side and hypotenuse, we will use cosine.
Based on the function
, we can solve for x. The adjacent side is 7 and the hypotenuse is 12. Plugging this in, we get
.
Now, we must use our inverse trigonometric functions to solve for x:
The inverse cosine and cosine on the left side cancel, leaving you with:
