I believe the answer is c, TSR
6:5
- there are 165 counters in the bag.
let the white counter be x
2x + x = 165
divide both sides by 3
there are 55 white counters in the bag
165-55=110
OR
2x= 165
divide both sides by 2
x= 110
- there are 110 black counters in the bag
- Martine takes 40%of the black counter
40%= 40/100×110
= 44.
- 44 black counters was taken out of the bag
- then there would be 66 black counters left I.e(110-44=66)
▪︎ there would be 66 black and 55 white counters in the bag.
- ratio of black counters to the white counter = 66:55
- reduced to the lowest term = 6:5 ( 11 divides 66 and 55 Into 6 and 5)
• the answer is 6:5
Answer:
Equation of tangent will be 
Step-by-step explanation:
We have given the function 
We have to find the equation of tangent at the point 
Equation of tangent is equal to 
So 
Now we have given point
So putting these points in the equation of tangent


Now equation of tangent passing through 


Answer:
y = -1/2x + b meaning f(x) = -1/2x + b
Step-by-step explanation:
Use two points on the graph that you can find the value of or use Slope = raise/run
let use points (2,0) and (0, 1)
slope = (change in the y-value)/(change in the x-value.
slope = (1 - 0)/(0 - 2)
slope = 1/-2 or -1/2
Or starting at point (2, 0) the run(x movement) = -2 and the raise is 1.
slope = raise/run
slope = 1/-2 or -1/2
Using one point (2,0) and the slope of -1/2, substitute into the slope intersect form, y = mx + b, and solve for "b" .
y= mx + b
0 = -1/2(2) + b
0 = -1 + b
1 = b
Now write your equation: y = mx +b where m = -1/2 and b = 1
y = -1/2x +b
