Answer:
Therefore a numeric equation using negatives can be written as
-11.94 = -1.94x 
Step-by-step explanation:
i) Amount <u>owed</u> by Steve = $11.94
ii) For every large coffee Steve has a <u>debit</u> of $1.99 applied to his account
iii) Let x be the number of days it has been since Steve last paid his bill.
therefore a numeric equation using negatives can be written as
-11.94 = -1.94x

6 servings = 3 people
1 cake=12 servings which feed 6 people
6/x=3/21
3x=126
x=42 servings
42 servings/12(amount of servings in a cake)=3.5. She will need to bake 4 cakes.
Answer:
6.4 kmph
Step-by-step explanation:
12.8/2=6.4 kmph
Answer:
D.
Step-by-step explanation:
h(x)=f(x)g(x) means multiply the expression for f to the expression for g.
That is the problem is just asking you to do (11x-5)(-2x-4).
Let's use foil.
First: 11x(-2x)=-22x^2
Outer: 11x(-4)=-44x
Inner: -5(-2x)=10x
Last: -5(-4)=20
------------------------Add together!
-22x^2-34x+20
D.
The function that represents how much more water can be added to the bucket before it overflows is given as follows:
c(x) = 6x³ + 3x² - 2x - 2.
<h3>How to define the function?</h3>
The function to calculate the space remaining in the pool is given by the subtraction of the capacity function by the function representing the current amount of water in the pool.
The functions in this problem are defined as follows:
- f(x) = 8x³ + 4x² - 6x + 5.
- g(x) = 2x³ + x² - 4x + 7.
Then the capacity function is obtained as follows:
c(x) = f(x) - g(x)
c(x) = 8x³ + 4x² - 6x + 5 - (2x³ + x² - 4x + 7)
Then the distributive property is applied to the negative sign as follows:
c(x) = 8x³ + 4x² - 6x + 5 - 2x³ - x² + 4x - 7.
Finally, the like terms are combined, that is, the terms that have the same variable and exponent, as follows:
c(x) = 6x³ + 3x² - 2x - 2.
