Answer:
Step-by-step explanation:
-5x - 1 = 2x + 6
-7x - 1 = 6
-7x = 7
x = -1
y = 2(-1) + 6
y = -2 + 6
y = 4
(-1, 4)
Answer:
Bucket 2
Step-by-step explanation:
Bucket 1 = 4700ml
Bucket 2 = 4.8l
Bucket 3 = 3880ml
Bucket 4 = 4.71 l
Convert holding capacity of bucket 1 and bucket 3 into liters
1 liter = 1000 milliliter
Bucket 1 = 4700ml
4700ml = 4.7l
Bucket 3 = 3880ml
3880ml = 3.88l
Therefore,
Bucket 1 = 4.7l
Bucket 2 = 4.8l
Bucket 3 = 3.88l
Bucket 4 = 4.71 l
The bucket closest to 5liters is bucket 2 with a holding capacity of 4.8 liters

Answer:
C. The zeros are -1 and 5/2, because f(x) = (x + 1)(2x-5).
Step-by-step explanation:
The zeros of the function are the values that make the factors zero. The factors need to multiply out to give the original standard-form equation.
The sign of the constant (-5) tells you the product of the constants in the factors must be -5. That is only true for choices B and C.
Additionally, the x-term needs to match the result of multiplying out the factors.
B. (x -1)(2x +5) = 2x^2 +3x -5 . . . . . . . . . wrong x-term (not -3x)
C. (x +1)(2x -5) = 2x^2 -3x -5 . . . . . . . . . matches the given f(x)
The factors of C are zero when x=-1, x=5/2.

Step-by-step explanation:
Since the word, 'of' means to multiply, whenever we see of multply the two numbers.
Then there are two ways to dothis, sicne to convert a percentage into a decimal, you devide by 100, we can either do this after we multiply or bfore, it doesn't matter so I'm going to do it after.
1. 520x100=52000/100=520
2. 20.25x3=60.75/100=.6075
3. .15x250=37.5/100=.375
4. 200x79=15800/100=158
5..3x80=24/100=.24
6. .28x50=14/100=.14
