Hello!
Equation: y = 2.50x + 47 rides.We can write an expression to show this scenario. Write this in the equation format y = mx + b:
m = rate of change, or cost per ride
b = initial cost, or cost to enter the fair
y = 2.50x + 4
Solve for the amount of rides possible with $21.50:
21.50 = 2.50x + 4
Subtract 4 from both sides to isolate x:
17.50 = 2.50x
Divide both sides by 2.50:
17.50/2.50 = 7 rides.
Which representations have the same rate of change of y with respect to x as the equation x + 2y = 6
The slope of all the given options are equal and it is equal to slope of given equation .
So, All of the above
Given
Equation of a given line is [tex]x+2y=6[/tex]
Lets find out slope m by writing the equation in y=mx+b form
[tex]x+2y=6\\2y=-x+6\\y=\frac{-1}{2}x+6[/tex]
The slope of the line is [tex]\frac{-1}{2}[/tex]
Now we find slope of each option using formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Lets pick two points from the graph to find out slope
Pick (0,3) and (6,0)
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\m=\frac{0-3}{6-0} =\frac{-1}{2}[/tex]
Now pick two points from option B to find slope
(-10,-3) and (0,-8)
[tex]m=\frac{-8+3}{0+10} =\frac{-1}{2}[/tex]
Now we consider the third option
[tex]y=\frac{-1}{2}x+2\\slope = \frac{-1}{2}[/tex]
Slope of all the options are same and it is equal to the slope of given equation
So, all the above

Which of the following shows that ABCD is a parallelogram for x=6 and y =8? (20 points)
Answer:
AB = CD = 44 and BC = AD = 31 ; so ABCD is a parallelogram
Step-by-step explanation:
A parallelogram should have two pairs of parallel sides meaning the length of side AB should be the same as the length of side CD and the length of side AD should be the same as the length of side BC.
First, lets see if line AB is parallel to line CD.
Let's start by finding out the length of line AB.
Since we know x = 6 we will replace x with 6 in the expression:
7(6) + 2 = 42 + 2 = 44
Now that we know the length of line AB is 44, lets find the length of line CD by replacing x with its value of 6:
9(6) - 10 = 54 - 10 = 44
Now that we know the length of line CD is 44, we can see that line AB is parallel to line CD since they both have the same length of 44.
Now, lets see if line BC is parallel to line AD.
Let's start by finding out the length of line BC.
Since we know y = 8 we will replace y with 8 in the expression:
3(8) + 7 = 24 + 7 = 31
Now that we know the length of line BC is 31, lets find the length of line AD by replacing y with its value of 8:
5(8) - 9 = 40 - 9 = 31
Now that we know the length of line AD is 31, we can see that line BC is parallel to line AD since they both have the same length of 31.
Conclusion
ABCD is a parallelogram because it contains two parallel sides.
Natalie works in a department store selling clothing. She makes a guaranteed salary of $300 per week, but is paid a commision on top of her base salary equal to 30% of her total sales for the week. How much would Natalie make in a week in which she made $225 in sales? How much would Natalie make in a week if she made xx dollars in sales?
Answer:
367.50
Step-by-step explanation:
300 + .30x (x = sales for week)
300 + (.30 * 225)
300 + 67.50
367.50

The rate of change is _______
apple(s) for every _______
tree(s).
Answer:
20 apples every 1 tree
Step-by-step explanation:
first, we need to find the constant!!
(constant means what you use to multiply in every equation)
so we do 100 apples divided by 5 trees!
the answer will be 20 apples and we know that we need to find how much PER ONE TREE
so, 1 tree = 20 apples !
Answer:
The second blank is 20 apples for every trees
Step-by-step explanation:
Sorry I didn't know the first blank...Hope this helps anyways!

Jacque needs to buy some pizzas for a party at her office. She's ordering from a restaurant that charges a \$7.50$7.50dollar sign, 7, point, 50 delivery fee and \$14$14dollar sign, 14 per pizza. She wants to buy as many pizzas as she can, and she also needs to keep the delivery fee plus the cost of the pizzas under \$60$60dollar sign, 60.
Each pizza is cut into 888 slices, and she wonders how many total slices she can afford.
Let PPP represent the number of pizzas that Jacque buys.
Answer:
7.50+14p<60
24 slices
Step-by-step explanation:
Step one: 60-7.50=52.50
Step two: 52.5/14= 3.75 which is 3
Step three: 3 * 8=24

Julio says, "If you subtract 12 from my number and multiply the difference by -5, the result is -40." What is Julio's number?
Answer:
Julio's number is 212
Step-by-step explanation:
(x - 12) ÷ -5 = -40
x - 12 = -40 times -5
x - 12 = 200
x = 200 + 12
x = 212
Check:
(x - 12) ÷ -5 = -40
((212 - 12)) ÷ -5 = -40
200 ÷ -5 = -40
-40 = -40
