ASAP: Which equation best represents the line of best fit for the data in the scatterplot above?
Answer:
F : y = -x + 4
Step-by-step explanation:
The first observation about this scatterplot is that the best line of fit will be a line going diagonally from top left to bottom right(or bottom right to top left)
Such a line has negative slope
Equation will be of the form
y = mx + b where m is a negative number
We can eliminate H and I since both lines have a positive slope which means that the line will go in a diagonal bottom left to top right direction
Let's examine options F and G
F: y = - x + 4
G: -9x + 3
Plug in some values for x from the graph and see which of the lines comes closest to the y values computed from the equations
At x = -5, the y value from the graph appears to be either 7 or 8
F: y = -x + 4 ==> -(-5) + 4 = 5 + 4 = 9; pretty close to graph's point value
G: -9x + 3 ==> -9(-5) + 3 = 45 + 3 = 48; this is greatly different from the graph value
At x = 0; the y value from graph is close to 4
From the equations we get
F: y = -x + 4 ==> y = -(0) + 4 = 4; pretty darn close
G: y -9x + 3 => y = -9 + 3 = -6; large difference
One more point
At x = 20, the point on the graph appears to be close to -19
From the equations we get
F: y = -x + 4 = -20 + 4 = -16; not too different
G: y = -9x + 3 = -9(20) + 3 = -180 + 3 = 177; way off
So the best line of fit would be
F : y = -x + 4
The equation that best represents the line of fit from the scatter plot is given as follows:
y = -x + 4.
How to define a linear function?The slope-intercept representation of a linear function is given by the equation shown as follows:
y = mx + b
The coefficients m and b have the meaning presented as follows:
m is the slope of the function, representing the increase/decrease in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, representing the numeric value of the function when the input variable x has a value of 0. On a graph, it is the value of y when the graph of the function crosses or touches the y-axis.From the scatter plot, we have that when x = 0, y = 4, hence the intercept b is given as follows:
b = 4.
When x = 20, y is approximately -16, hence the slope m is obtained as follows:
-16 = 20m + 4
20m = -20
m = -1.
Hence the function is:
y = -x + 4.

Hailey goes to a restaurant and the subtotal on the bill was x dollars. A tax of 7% is applied to the bill. Hailey decides to leave a tip of 20% on the entire bill (including the tax). Write an expression in terms of x that represents the total amount that Hailey paid.
The total amount that Hailey paid can be represented by the following expression in terms of x:
Total amount = x + 0.07x + 0.20(x + 0.07x)
Simplifying the equation, we get:
Total amount = x + 0.07x + 0.20(1.07x)
Total amount = x + 0.07x + 0.214x
Total amount = 1.284x
Therefore, the expression in terms of x that represents the total amount that Hailey paid is 1.284x.
Kelly wants to make a fruit salad made up of bananas, apples, and peaches. She wants to mix one part apples, 2 parts peaches, and 3 parts bananas. Bananas cost $2.00 per pound, apples cost $4.00 per pound, and peaches cost $5.00 per pound. Kelly only has $10.00, and will spend it all on fruit salad. Write an equation and use this equation to determine how many pounds of fruit salad he can make.
Step-by-step explanation:
If x is the pounds of apples, 2x is pounds of peaches, and 3x is pounds of bananas, then the total cost is:
4(x) + 5(2x) + 2(3x) = 10
4x + 10x + 6x = 10
20x = 10
x = 0.5
Kelly buys 0.5 pounds of apples, 1 pound of peaches, and 1.5 pounds of bananas, for a total of 3 pounds of fruit.

A triangle has angles of 124°, 28°, and 28°. Explain whether or not the triangle can have its three side lengths equal to 7 units, 6 units, and 14 units.
No it cannot. There are a couple of ways to prove this. The easiest way is that we know by looking at the angles that we have an Isosceles triangle, because we have 2 angles of the same value. We know that an Isosceles triangle must have at least 2 sides of the same length, which means that this triangle cannot have the side lengths listed.

ONLY PEOPLE WITH REAL AWNSERS!!
Answer:
7:20 p.m.
Step-by-step explanation:
First, we can find the distance that each friend will be from their house at the time when they meet each other.
To find this, we can multiply the ratio [tex]8 \text{ mi} : 7 \text{ mi}[/tex] by a constant such that the sum of both numbers in the ratio is 20, since the friends' houses are 20 miles apart. Solving for this constant:
[tex]\dfrac{20}{7 + 8} \\ \\ = \dfrac{20}{15} \\ \\ \boxed{=\dfrac{4}{3}}[/tex]
Multiplying the constant by both sides of the ratio:
[tex]\dfrac{4}{3}\left(8 \text{ mi}) : (7 \text{ mi}\right)\dfrac{4}{3}[/tex]
[tex]\boxed{= \dfrac{32}{3} \text{ mi} : \dfrac{28}{3} \text{ mi}\right)}[/tex]
So, we know that the first friend will have traveled 32/3 or 10 2⁄3 miles when they meet, and the second friend will have traveled 28/3 or 7 1⁄3 miles.
Now, to calculate what time they will meet, we can divide how far one of the friends has traveled by how fast they were traveling. This will give us the minutes it will take them to get to the meeting place. We can then add that amount of minutes to 6:00 p.m. to calculate when they will meet.
I will use the fast friend (traveling at 8 mph).
[tex]\dfrac{32}{3} \text{ mi} \cdot \dfrac{60 \text{ min}}{8 \text{ mi}}[/tex]
— Also note that I substituted 1 hour for 60 minutes in the mph ratio.
[tex]= \dfrac{32}{3} \not\text{mi} \cdot \dfrac{60 \text{ min}}{8 \not\text{mi}}[/tex]
[tex]= \dfrac{32 \cdot 60}{3 \cdot 8} \text{ min}[/tex]
[tex]= \dfrac{32}{8} \cdot \dfrac{60}{3} \text{ min}[/tex]
[tex]= 4 \cdot 20 \text{ min}[/tex]
[tex]\boxed{= 80\text{ min}}[/tex]
Adding those minutes to 6:00, noting that 80 min = 1 hr 20 min:
[tex]\text{ } \ \, 6\!:\!00 \text{ p.m.}\\\underline{+ 1\!:\!20}\\\\\text{ }\, \boxed{7\!:\!20 \text{ p.m.}}[/tex]
So, the friends will meet at 7:20 p.m.

I need help on a b and function 2
I dont get it
Answer:
For A: The first function has a greater ROC
For B: The first function has a negative slope
Step-by-step explanation:
Explication for A:
We already know that the R.O.C. (slope) is 2 for the first function, so all we need to do is substitute the values in the table into the following formula: y2-y1/x2-x1
after substituting: (-3-(-6))/(0-(-1))
simplify 3/1=3, since the ROC is 3, the second equation has a greater ROC than the first
Explanation for B:
The first function described is f(x)=20-3.5x
This is because the y intercept is the starting point, or how much money she has in the gift card. She spends 3.5 dollars per week, so we add a variable to represent the number of weeks, and its negative since she is spending, not earning. We also know that the slope is negative since y is decreasing as x is increasing, on the table.
The second function described is c(m)=5x+10
This is because the equation represents the total cost of renting a calculator, so both terms are positive.
What is the area of the figure below
Answer:224
Step-by-step explanation:
Okay as you can see, the figure is divided into 3 shapes. 2 rectangles and a right trapezoid.
You can solve the area of the rectangle on the far right by doing 9x6 leaving you with 54.
For the other rectangles you can do 11x12 equaling 132. I got 11 because you know the top is 17 and as you see at the bottom that length you used for the first rectangle is 6, so you do 17-6. You get 12 from adding 9+3.
For the right trapezoid the formula is A = ( a + b ) x h/2. So you can plug it in and say A=(12+7) x 4/2= 38.
You then add all the areas together (54+132+38= 224) leaving you with the answer of 224.
