Answer:
<h2>D. 76</h2>
Step-by-step explanation:
Put x = 4, y = -5 and z = 2 to the expression 3x² - 4y + xz and use PEMDAS:
3(4)² - 4(-5) + (4)(2)
= 3(16) + 20 + 8
= 48 + 20 + 8
= 76
<u>Answer:</u>
<u>No, this is not a rational number.</u>
This is an irrational number because it's not rational. There isn't a possible ratio for that number.
Answer:
M(3.5, 1)
Step-by-step explanation:
Midpoint formula
x1+x2/2
y1+y2/2
-6 + 13/2 = 3.5
-6 + 2/2 = 1
Solve for y:
3x = 7y + 21
~Subtract 7y to both sides
3x - 7y = 21
~Subtract 3x to both sides
-7y = 21 - 3x
~Divide -7 to both sides
y = -3 + 3/7x
~Change order
y = 3/7x - 3
Best of Luck!
Answer:
