Answer:
2
Step-by-step explanation:
A coefficient is a number of times a variable. So in this equation. 2 is being multiplied by y. so 2 is the coefficient.
Answer:
B. y= -4x + 28
Step-by-step explanation:
To find the equation of this line first put it into slope-point form, 
where 
and 
are the y and x coordinates and m is the slope. So plug in the information to get the equation, y-8=-4(x-5). Then solve for y,
First, distribute the -4
y-8=-4x+20
Next, add 8 to both sides
y=-4x+28
Answer:
8.5 for each student ticket
Step-by-step explanation:
Simply divide the total cost 42.5 by the amount of students 5 to get your answer.
42.5 / 5 = 8.5
Answer:
2^3 * 5^2
Step-by-step explanation:
We need to break 200 down into prime numbers
200 = 20*10 These are not prime
= 4*5 * 2*5 The 4 is not prime
= 2*2*5 * 2*5 This is prime
Rearranging
= 2*2*2*5*5
= 2^3 * 5^2
Equation of a circle:
(x - h)^2 + (y - k)^2 = r^2
In this case:
<span>center (2,7) and radius 4 so h = 2, k = 7 and r = 4
</span>Equation:
(x - 2)^2 + (y - 7)^2 = 4^2
(x - 2)^2 + (y - 7)^2 = 16
Hope it helps.
