Answer:
c.15+2z/6x-12y
f.7a+b/4a-6b
Step-by-step explanation:
z+1/x-2y - 2x-3/2x-4y + z/3x-6y
z+1/x-2y - 2x-3/2(x-2y) + z/3(x-2y)
6(z+1)-3(2z-3)+2z
15+2z/6x-12y
3a/2a-3b - a+b/2(-3b+2a)
6a+a+b/2(2a-3b)
7a+b/4a-6b
The vertex is in essence the turning point of the parabola y = x²<span> − 10x + 2
the x coordinate of the turning point = </span>

=

= 5
when x = 5, y = (5)² - 10(5) + 2
= -23
Thus coordinate or vertex is ( 5, -23)
First, you need to get the variable by itself.
Divide three by both side.
c = -7

One ton = 2000 lbs
Therefore, 1.5 tons = 3000 lbs
3000-300=2700lbs
Answer:
87.8
Step-by-step explanation:
So you have to multiply 91 times 3.5 which equals 318.5
91 × 3.5 = 318.5
Then divide 318.5 by 100 which equals 3.185
318.5 ÷ 100 = 3.185
Next subtract 91 by 3.185 which equals 87.815
91 - 3.185 = 87.815
Last Round 87.815 to 87.8
87.8 should be the answer
Hope this helps
