Answer:
fragrance A $26
fragrance B $24
Fragrance A has the greater unit rate
Step-by-step explanation:
To find the price of fragrance A , take the price and divide by the number of bottle
$78/3 bottles = $26 per bottle
To find the price of fragrance A , we can look at the graph and find the price for 1 bottle on the x axis and go up until we hit the red line. The value of y is 24 dollars
Step-by-step explanation:
the leading coefficient means the coefficient (factor) of the term with the highest exponent of the variable (typically x).
with sufficiently large values of this variable (x - going far enough to the right) this term will "win" in value against any other term of the polynomial expression.
and therefore the sign of its factor (coefficient) will determine, if the curve will go up or down.
a positive factor (coefficient) will make the value of this term and therefore of the whole polynomial larger and larger, making the curve going up to +infinity.
a negative factor (coefficient) will make the value of this term and therefore of the whole polynomial smaller and smaller (more negative and more negative), making the curve going down to -infinity.
Step-by-step explanation:
The ratio is 4:3
First you would do 4 + 3 which is 7
Then you would do 35 ÷ 7 which is 5
Finally we would multiply 5 to the ratio 4:3
So 7 × 4 is 28
And 7 × 3 is 21
So the new ratio is 28:21
So there are 21 girls in the class
Hope this makes sense
Answer:
The solution is x = -2, y = 4.
Step-by-step explanation:
2x + 4y = 12
x + y = 2
From the second equation: y = 2 - x.
Now substitute for y in the first equation:
2x + 4(2 - x) = 12
2x + 8 - 4x = 12
-2x = 4
x = -2.
Now find y by substituting x = -2 in the second equation:
- 2 + y = 2
y = 4.
