Fifty-six biscuits are to be fed to 10 pets; each pet is either a cat or a dog. each dog is to get six biscuits, and each cat is to get five. how many dogs are there?
Answer: There are 6 dogs
Explanation:
Total number of biscuits = 56
Total number of Pets = 10
Now each dog is to be given 6 biscuits and each cat is to be given 5 biscuits.
Now if there are 6 dogs and each is to be given 6 biscuits and total biscuits given to 6 dogs = 6 x 6 =36
and there are 4 cats and each is to be given 5 biscuits and total biscuits given to 4 dogs = 4 x 5 =20
Therefore, total biscuits given to 6 dogs and 4 cats is 36+20= 56
Answer:
1. y = -2x + 5
2. y = 3/5x + 5
3. y = -4/5x - 4
4. y = - 1
5. yes
6. yes
7. yes
8. no
Step-by-step explanation:
1. (4,-3) parallel to y= -2x
-3 = -2(4)+b
b=5
2. (-5,2) parallel to y = 3/5x
2= 3/5(-5)+b
b=5
3. (-5,0) -4/5x
0 = -4/5(-5)+b
b = -4
4. (-4,-1)
y= -1
5. yes
6. yes
7. yes
8. no
- Same slope = parallel ex. y = -5x +7, y = -5x +12
- opposite reciprocal = perpendicular ex. y = -5x +7, y = 1/5x + 12
- to find "b" with slope and point
(x,y) y = mx + b
plug in the y value and x value in the eqaution and m=slope, solve for b
