Answer:
it is isosceles triangle with an angle = 90. Two others angle are equal. sum of all angles in triangle is 180.
2x + 90=180 --> x=45
Answer:
6
Step-by-step explanation:
The parentheses mean to multiply, in this case, so -3 times -2 would equal 6.
26 - 14 = 12
12 ÷ 4 = 3
26 - 3 = 23
23 - 3 = 20
20 - 3 = 17
14, 17, 20, 23, 26
Answer: The three missing arithmetic means in this sequence are 17, 20, 23.
Answer:
is valid for all values of x ≥ 0
Step-by-step explanation:
Y =2x +14
-4x –y = 4 so y = -4x – 4
2x + 14 = -4x – 4
2x + 4x = -4 - 14
6x = -18
x = -18/6
x = -3
Y =2x +14
y = 2(-3) +14
y= -6 +14
y=8
answer:
y-coordinate is 8
