A new operation is defined by a△ b = a(2) - b / b- a(2) . Find the following
values.
2 △ 1/2
5 △ (−3)
Answer:
-1-1Step-by-step explanation:
The expression simplifies as follows:
aΔb = (a² -b)/(b -a²) = -(b -a²)/(b -a²) = -1 . . . . . for b≠a²
That is, for any values of 'a' and 'b', the expression evaluates to -1.
2 Δ 1/2 = -1
5 Δ -3 = -1
_____
Additional comment
The purpose of simplifying the expression is to avoid having to do unnecessary arithmetic. If you actually want to see the arithmetic, it looks like this:
2 Δ 1/2 = (2² -(1/2))/(1/2 -2²) = (7/2)/(-7/2) = -1
5 Δ -3 = (5² -(-3))/(-3 -5²) = 28/-28 = -1

On a field trip, there must be on adult for every 8 students. If 32 students go on the field trip, how many adults must attend?
Answer:
4 adults
Step-by-step explanation:
To find the number of adults, you simply take the total number of students divided by the number of students you want in a group.
So you would just do:
32/8
Answer:
32/8=4 adults that are able to attend

5. Describe a line with a positive, negative, O and undefined slope.
ALGEBRA I Semester 1
Answer:
A line that has a positive slope would rise upwards from left to right of the graph, increasing.
A line that has a negative slope would fall downwards from left to right of the graph, decreasing.
A line that has an undefined slope would look like a straight (horizontal/vertical) line from left to right/bottom to the top of the graph, neither increasing nor decreasing.

Answer: 56 14 84 in order
Step-by-step explanation:
8 x 7 = 56 so it is in the first box
4 x 7 / 2 = 14 so it is in the second box
56 + 14 + 14 = 84 so it is in the third and last box
The area of the parallelogram using area of rectangle and area of two triangles is 84 m²
How to find area of a parallelogramArea of a rectangle = length × width= 8m × 7m
= 56 m²
Area of each triangle = 1/2 × base × height= 1/2 × 4m × 7m
= 1/2 × 28
= 14m²
Total area of triangles = 2(14 m²)= 28 m²
Area of parallelogram = area of rectangle + area of two triangles= 56 m² + 28 m²
= 84 m²

Match each graph with the correct equation written in
standard form. Explain your reasoning.
The graphs and their equations are:
Line 1: 6x - 2y = -10Line 2: 9x - 9y = -45Line 3: 3x - 12y = -60How to determine the equations of the graphsThe three lines are linear equations, because they are all straight lines.
Also, the lines have the same y-intercept (this is so, because they cross the y-axis at the same point), but they have the same slope
Next, we rewrite the equations in slope-intercept form.
So, we have:
[tex]3x - 12y = -60[/tex]
Divide through by -12
[tex]-0.25x +y = 5[/tex]
Make y the subject
[tex]y = 0.25x + 5[/tex]
[tex]6x - 2y = -10[/tex]
Divide through by 2
[tex]3x - y = -5[/tex]
Make y the subject
[tex]y = 3x + 5[/tex]
[tex]9x - 9y = -45[/tex]
Divide through by -9
[tex]-x + y = 5[/tex]
Make y the subject
[tex]y = x + 5[/tex]
Line 1 has the highest slope, while line 3 has the least slope.

You saved $260 on your new laptop because you bought it online. If this was a 5% savings from the original price, find the original cost of the laptop.
Answer:
The original cost of the laptop was $5200
Step-by-step explanation:
we can set up an algebraic equation and solve for the variable.
the variable is going to be the original price because that is what we need to find.
So, x= the original cost of the laptop
let's also convert 5% to a decimal by moving the decimal 2 to the left. So 5% is 0.05
0.05x=260 divide both sides by 0.05 to isolate the variable
0.05x/0.05= 260/0.05
x=5200
We can also check our work by taking 5% of 5200. And 5% of 5200 is 260. In other words, if the laptop cost $5200, buying it online at a 5% savings would save you $260

What fraction of 3 is 2 2/5
Answer: 2 2/5 is 4/5 of 3
Step-by-step explanation:
We can view that as what do we multiply 3 by to get 2 2/5 and call that value x
3x = 2 2/5
x = (2 2/5)/3
Let's turn 2 2/5 into an improper fraction... 2 2/5 = 12/5
So we have
x = (12/5)/3 = (12/5)(1/3) = 4/5
Thus 2 2/5 is 4/5 of 3
Verify: 3(4/5) = 12/5 = 2 2/5

*6x^2y^2
*9x^2y^4
Answer:
9x^2y^2
Step-by-step explanation:

The area of a parallelogram is six square units. Both the height and the length of the base are whole numbers. What are the possible length and height?
well, the area of a parallelogram is simply A = bh.

6 = 2 * 3
2 and 3 are both prime, in how many ways can we arrange them? just 2 and 3 or 3 and 2, so those are the only possible values for "b" and "h".
