Answer:
-4
Step-by-step explanation:
Find the gradient of the line segment between the points (0,2) and (-2,10).
Given data
x1= 0
x2= -2
y1= 2
y2=10
The expression for the gradient is given as
M= y2-y1/x2-x1
substitute
M= 10-2/-2-0
M= 8/-2
m= -4
Hence the gradient is -4
Slide 14: you have to measure it
Slide 11: No they do not form a proportion because they are not related. You can do 20 push ups per minute, while your friend can do 19.
Slide 15: 4. Actual is 15 5. Actual is 35 6. Model is 4 7. Model is 2.5
Slide 13: 1. Proportional 2. Proportional 3. Not proportional 4. Proportional
Slide 12: m=77 a=10 g=16 w=160
Hope I’m not too late!
Answer:
56060550
Step-by-step explanation:
555x101010=56060550
That’s a lot of zombies and I’m scared now.
This is a great place and time to apply synthetic division. Since you are dividing the 3rd order poly by (a+2), let the divisor in synth. div. be -2.
Then:
_________________
-2 / 1 6 12 8
_____-2_-8 -8____________
1 4 4 0
Since there is no remainder, -2 is a root and (x+2) is a factor of the poly.
The quotient comes from those coefficinets 1 4 4
and is 1a^2 + 4a + 4, whose factors are (a+2)^2.

3:4 = 7
3/198 = 7/x
solve for x using cross multiplying
3/198 = 7/x
198(7) = 3x
1386 = 3x
/3 /3
462 = x
Therefore, there are 462 workers.
Proof:
3/198 = 4/x
198(4) = 3x
792 = 3x
/3 /3
264 = x
264 + 198 = 462.
264 / 4 = 66
198 / 3 = 66
462 / 7 = 66
