Answer:
x = 3
y = 0
z = 8
Step-by-step explanation:
a) 3x + 3y - z = 1
b) z = 8
c) -x -3y + 2z = 13
a) 3x + 3y - 8 = 1 (substitution)
a) 3x + 3y = 9
c) - x - 3y + 2(8) = 13 (substitution)
c) -x - 3y + 16 = 13
c) -x - 3y = -3
(3x + 3y = 9) + (-x -3y = -3)
= 2x = 6
x = 3
a) 3(3) + 3y - 8 = 1
9 + 3y - 8 = 1
y = (1 -9 + 8)/3
y = 0
Answer:
9.5
Step-by-step explanation:
(0.5^2 + 0.5^-2 + 0.5) / 0.5 = 9.5
Hope this help! :)
Answer:
D. It would be less steep.
Step-by-step explanation:
→When the absolute value of the number in front of x is greater than 1, the function on the graph narrows. When the absolute value of the number in front of x is less than 1, the function on the graph widens.
<u>In this case, the number is less than 1, making it grow wider. And as a result of it growing wider, it also becomes less steep.</u>
Answer:
The answer is B. 70
Step-by-step explanation:
First, since K is the midpoint of line segment JL, JK must equal KL.
So, set 9x-1 = 2x+27 and solve.
7x=28 so x=4
Then, since they are asking for JL, using x=4, add together JK and KL.
So, 9x-1+2x+27 = 11x+26 = 11(4) + 26 = 44+26 = 70
