Answer:
A) x = 12
Step-by-step explanation:
if its a right angle? then the angle in total is 90 degrees,
subtract the 35 from 90 to get 55 degrees,
4x + 7 = 55 solve this
4x = 48
x = 12
Answer:
D
Step-by-step explanation:
first of all, what is mode: it is the highest occuring number in a set of numbers.
now since 12 is supposed to be the mean and it occurs twice but 9 also occurs twice so for 12 to be the mode, we must add one more 12.
therefore the answer is 12
Answer: y = 3/2x + 1
Step-by-step explanation: For a perpendicular line, take the reciprocal of "m" and reverse the sign.
- 2/3 becomes +3/2
Then substitute the y and x values of the given coordinate into the equation and solve for "b"
y = mx + b
-2 = 3/2(-2) + b
-2 = -3 + b
-2 +3 = b
+1 = b Substitute for b in y = (3/2)x + 1
Divid the differince of the x's by 2 and the diffence of the y's also by 2
8/2,4/2 is (4,2)
M=(4,2)
hope this helps
