Let us assume that cost of each granola bar be $x and that of a cup of yogurt be $y  
From person A's purchase, we get  
12x + 7y = 15.5; equation A  
And from person B's purchase, 
6x + 11y = 11.5; equation B  
Let us multiply equation B by 2 and subtracting equation A from it, we will get  
12x + 22y - 12x - 7y = 23 - 15.5,  
=> 15y = 7.5 
or, y = 0.5  
Substituting value of y in equation A, we can find x  
12x + 7*0.5 = 15.5 
=> x = (15.5 - 3.5)/12 
or, x = 1  
Therefore, cost of granola bar is $1, and that of yogurt is $0.5

The graph of the parent function f(x) = x3 is transformed such that g(x) = f(–2x). How does the graph of g(x) compare to the gra
Anni [7]

Answer:

b) g(x) is stretched horizontally and reflected over the x-axis.

Step-by-step explanation:

The given parent function is

f(x) =  {x}^{3}

The transformed function is

g(x) = f (- 2x)

We want to see how the transformed graph compares with the parent graph.

The negation inside means all x-coordinates we're negated.

This means, there is a reflection in the y-axis.

The factor of 2 within the function means a horizontal stretch by a factor of 1/2.

The correct answer is B.

What does the remainder theorem conclude given that f(x)x+3 has a remainder of 11?
Slav-nsk [51]

By the remainder theorem of polynomial division, the complete equation is f(-3) = 11

<h3>How to complete the blanks?</h3>

The equation is given as:

f(x)/x + 3

Set the divisor to 0

x + 3 = 0

Solve for x

x = -3

Given that the quotient has a remainder of 11.

It means that:

f(-3) = 11

Hence, the complete equation is f(-3) = 11

What does it mean to find the sin, cos, and tan of the angle θ?
djyliett [7]
Sin means to divide the opposite side measure by the hypotenuse. Cos is equal to the adjacent side value divided by the hypotenuse. Tan is equal to the opposite value divided by the adjacent. To remember this, I use the abbreviation SOHCAHTOA. SOH for Sin is Opposite over Hypotenuse, and so on.

2% of the students at Hamilton Middle School have red hair. There are 700 students at Hamilton Middle
Makovka662 [10]

Answer:

14 students

Step-by-step explanation:

We can set up a percentage proportion to find 2% of 700.

\frac{x}{700} = \frac{2}{100}, and we can use the cross products property to find the value of x.

700\cdot2=1400\\\\1400\div100=14

Hope this helped!
