Answer:
14 ounces of blue paint
Step-by-step explanation:
The ratio of blue to yellow is 2:7
To solve this problem we can make a proportion:
2/7=x/49
the numerator represents the blue paint, the denominator represents the yellow paint
To solve the proportion you have to cross multiply:
2*49=7*x
x=14
She needs to add 14 oz of blue paint
I hope this helps :)
Let the number of hours she works be x
2x+15 15 more than twice the
3x-15 15 less than 3 times the hours she worked
2x+15=3x-15
3x-2x= 30
x= 30
the number of hours she worked is 30
Answer:
Step-by-step explanation:
To start, lets form our polynomial factors from our zeroes.
x = -2
x + 2 = 0
x = 5
x - 5 = 0
Now lets put these into factored form by moving them into parenthesis and multiplying them with each other!
(x+2)(x-5)
We can start moving them out! I am going to use FOIL, but you could also use distributive or any other method/property.
x · x = x²
x · -5 = -5x
x · 2 = 2x
2 · 5 = 10
Now lets put our terms into our polynomial function, based on the order of the powers.
We are done! Hope this helps!
Answer:
Quadratic
Step-by-step explanation:
This is a quadratic equation because it's in the form of y=ax^2+bx+c
If it were linear, the graph would be a straight line and wouldn't contain a second degree term
If it were exponential there would be a growth or decay factor
