Each bracelet is $5, this can be represented as 5b. (Where b is number of bracelets)

Each necklace is $8, this can be represented as 8n. (Where n is number of necklaces)

We know that the total money raised needs to be at least $100, but it can also be more than that.

So we know that 8n+5b will be greater than or equal too 100.

8n+5b ≥ 100

A candy store sells bags of fruit-flavored candy for $2 and chocolate candy for $3. Jasmine spends $54 on candy for her friends.

Answer:

2x + 3y = $54

Step-by-step explanation:

Standard Form ~ Ax + By = C

A and B in this case are just going to be numbers, they are just for substitution purposes.

Since x is fruit flavored candy and y is Chocolate, we can substituce the Fruit for A and Chocolate for B.

Now, we have 2x + 3y = C

The C is going to be the total cost. Therefore we have ~

2x + 3y = $54

Have a great day,

Answer:

4. Slope of function B = -slope of function A

Step-by-step explanation:

Given:

Function A is given as:

$F(x)=-2x+1$

The above equation is of the form $y=mx+b$ , where $m$ represents slope of the line.

Therefore, on comparing the function A with the above standard form, er conclude that, slope of function A is -2.

Now, from the graph of function, we consider any two points on the graph and determine the slope of the line using the two points.

Let us consider the points $(x_1,y_1)=(1.5,0)\ and\ (x_2,y_2)=(3,3)$

Now, the slope of the line passing through these two points is given as:

$m_B=\frac{y_2-y_1}{x_2-x_1}=\frac{3-0}{3-1.5}=\frac{3}{1.5}=2$

Therefore, slope of function B is 2.

Therefore, the correct relation between the slopes of the two functions is that the slope of function B is negative of the slope of function A.

$m_B=-(m_A)=-(-2)=2$
