Barney and Robin went shopping at H&M. The store was having a sale on all shirts and pants. Barney spent $70 on 3 shirts and 2 pairs of pants and Robin bought 1 shirt and 4 pairs of pants for $90. d) Use a graphing calculator, to graph your equations in parts a and b. What is the coordinate point where these two lines intersect? How does this compare to your response in part c?
Barney spent $70 on 3 shirts and 2 pairs of pants
Robin bought 1 shirt and 4 pairs of pants for $90
Let x be the cost for each shirt
Let y be the cost for each pair of pants
3x+2y=70 (1)
x+4y=90 (2)
Having this system of equations, we can graph on the graph calculator:
The solution of two linear equations corresponds to the intersection of the two lines because the coordinate pair naming every point on a graph is a solution to its corresponding equation:
In this case the solution is: (10, 20) and corresponds to the cost of the shirt and pant.
Shirt: $10
Pant:$20
Patrick is buying rabbits. This graph shows how the total cost depends on the number of rabbits purchased.
Using the graph provided, we must find how many rabbits correspond to a cost of $20.
To find the number of rabbits, we look for the value $20 on the vertical axis, then we follow a horizontal line to the curve, and then we go down vertically to the horizontal axis. We find that the number of rabbits is 5.
We see that we have a linear relationship between the number of rabbits and its cost. If 5 rabbits cost $20, each rabbit costs $20/5 = $4 (we can also find this value looking at the graph).
Using the cost of each rabbit, we have that:
• 5 rabbits cost $4 * 5 = $20,
,• 8 rabbits cost $4 * 8 = $32,
,• 12 rabbIts cost $4 * 12 = $48.
Answer
5 rabbits cost $20,
8 rabbits cost $32,
12 rabbIts cost $48.

Spinning the second wheel determined which "bonus survival tool" they would be allowed to bring, along with a few other necessary items. A tent Matches Desert 4 1 Rainforest 3 1 Mountain peak 1 1 What is the probability that a randomly selected participant spun the second wheel and landed on a tent given that the participant spun the first wheel and landed on mountain peak? Simplify any fractions.
Answer:
1/2
Explanation:
Taking into account the table, we know that 2 participants spun the first wheel and it landed on a mountain peak and 1 of those participants spun the second wheel and landed on a tent. So, we can calculate the probability as:
[tex]P=\frac{1}{2}[/tex]Because there are 2 people on a mountain peak and for one of them landed on a tent.
Therefore, the answer is 1/2
Write the equation of the line that passes through the points (-2,-2) and (8,0)
Considering the expression of a line, the equation of the line that passes through the points (-2,-2) and (8,0) is y= -1/5x + 8/5.
Linear equationA linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope m of said line can be calculated using the following expression:
m= (y₂ - y₁)÷ (x₂ -x₁)
Substituting the value of the slope m and the value of one of the points in the expression of a linear equation, the value of the "b" can be obtained.
Equation of the line in this case
Being (x₁, y₁)= (-2, 2) and (x₂, y₂)= (8, 0), the slope m can be calculated as:
m= (0 - 2)÷ (8 -(-2))
m= (0 - 2)÷ (8 +2)
m= (-2)÷ (10)
m= -1/5
Considering point 1 and the slope m, you obtain:
2= (-1/5)×(-2) + b
2= 2/5 +b
2 -2/5= b
8/5= b
Finally, the equation of the line is y= -1/5x + 8/5.

From the table we can see that sides double in 1st, 2nd and 4th case
So comparing them
When side =1 then Surface area = 6 cm sq
When side = 2 then Surface area = 24 cm sq
Here we can see that when the side doubles, the surface area quadruples
Similar result is obtained when in relation of side = 2 and side 4

This is super confused im not the best with graphs
ANSWER
C. The function is negative when x < 0
EXPLANATION
We want to identify the statement that best describes the function graphed.
To do this, we have to study the graph of the function.
The function graphed has both positive and negative values. The positive values of the function are the part of the function that is above the horizontal red line while part of the negative values of the function is the part of the function that is below the horizontal red line.
We notice that the part of the function that is below the horizontal red line occurs when x is less than 0 (the part of the graph to the left of the vertical red line).
Hence, we can conclude that the correct statement that describes the function is:
The function is negative when x < 0. The answer is option C.

[tex]\begin{gathered} \frac{\frac{1}{2}}{\frac{35}{6}} \\ \\ =\frac{1}{2}\div\frac{35}{6} \\ \\ \text{ Flip the fraction on the right and change the division symbol to mutilication:} \\ =\frac{1}{2}\times\frac{6}{35} \\ \\ =\frac{1\times6}{2\times35} \\ \\ =\frac{6}{70} \\ \\ =\frac{3}{35} \end{gathered}[/tex]After simlifying, we have:
[tex]\frac{3}{35}=\frac{3}{35}[/tex]Since the equation is true, we can say the proortion is true because it has a constant ratio.
