Step-by-step explanation:
A is the correct answer of this question
The slopes that could have be plotted on the coordinate grid are -7 and 1/7
Before we determine the required slope of the two lines, we must understand that:
Two lines are perpendicular if the product of their slope is -1if the slope of a line is m, the slope of the line perpendicular will be -1/mSo, we choose the options that the product of the slopes equals -1
For option A:
[tex]product = 2 \times 1/2\\product = 1[/tex]
Hence option A is incorrect
For option B;
[tex]product = 4 \times - 4 = -16\\[/tex]
Hence option B is incorrect
For option C.
[tex]product = 1/3 \times 1/3\\product = 1/9[/tex]
Hence option C is incorrect
For option D;
[tex]product = -7 \times 1/7\\product = -1[/tex]
This shows that the slopes that could have been plotted on the coordinate grid are -7 and 1/7

Apply the distributive property to create an equivalent expression 1/5(15+10k)
Answer:
3 + 2k
Step-by-step explanation:
1/5(15+10k)
distribute
1/5 * 15 + 1/5 * 10k
3 + 2k
Answer:
3 + 2k
Step-by-step explanation:
First, I am going to explain what the distributive property is. Lets say he had the expression a(b + c). We can "distribute" the a to the b and c:
a(b + c) = ab + ac
We can apply the distributive property to the expression 1/5(15 + 10k):
1/5(15 + 10k)
= (1/5)(15) + (1/5)(10k)
= 3 + 2k
By using the distributive property, we found the expression 3 + 2k.

Properties of Special Triangles:
Calculate the size of angle AEF
Answer:
90 degrees
Step-by-step explanation:
Answer:
The angle of AEF is 90°.
Step-by-step explanation:
Given that DEF is an equilateral triangle so all angles are the same which is 60° and in a regular square, all angles are 90°. Next, we have to find ∠ADE :
∠EDF = 60° / ∠CDF = 180° / ∠CDA = 90°
∠ADE = 180° - ∠EDF∠CDA
∠ADE = 180° - 60° - 90°
∠ADE = 30°
Given that ADE is an isosceles triangle so ∠ADE and ∠AED have the same angles. Lastly, we have to find ∠AEF by adding ∠AED and ∠DEF together :
∠AED = 30° / ∠DEF = 60°
∠AEF = ∠AED + ∠DEF
∠AEF = 30° + 60°
∠AEF = 90°
if DE = 4x - 1, EF = 9, and DF = 9x - 22, find the value of x.

The multiplication of (2.4)(–1.8) and (0.6)(–0.4) gives negative values option third is correct.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
As we know, by the arithmetic operation rule
Multiplication of two negative values is positive.
Multiplication of one negative and one positive value is negative.
Multiplication of two positive values is positive.
In option third:
(2.4)(-1.8) = -4.32
(0.6)(-0.4) = -0.24
Thus, the multiplication of (2.4)(–1.8) and (0.6)(–0.4) gives negative values option third is correct.

Four friends administered a bake sale table for a day. They made a total of $376.35 over the course of the day. Determined to give everyone an equal share of the money, each friend received $94.0875.
A. This statement makes sense. Dividing 376.35 by 4 results in 94.0875.
B. This statement does not make sense. Money values must be rounded to the nearest dollar. Each friend should receive $94.
C. This statement does not make sense. Money values must be rounded to the nearest cent. Each friend should receive $94.08.

[tex]5 \times (5 + x) = 6 \times (6 + 12) \\ 25 + 5x = 6 \times 18 \\ 25 + 5x = 108 \\ 5x = 108 - 25 \\ 5x = 83 \\ x = \frac{83}{5} \\ x = 16.6[/tex]
On a 210-mile trip, Cameron drove at an average speed of 60 miles per hour for the first x hours. He then
completed the trip, driving at an average speed of 50 miles per hour for the remaining y hours. If x = 1,
what is the value of y?
y =
Answer:
[tex]y = 3[/tex]
Step-by-step explanation:
Given
Trip = 250 miles
Speed for first x hours = 60 miles/hour
Speed for next y hours = 50 miles/hour
x = 1
Required
Find y
To solve this question, we'll make use of:
[tex]Distance = Speed * Time[/tex]
For x hours:
[tex]Distance = 60miles/hour * x[/tex]
Substitute 1 hour for x
[tex]Distance = 60\ miles/hour * 1\hour[/tex]
[tex]Distance = 60\ mile[/tex]
For y hours:
[tex]Distance = 50\ miles/hour * y\ hours[/tex]
[tex]Distance = 50y\ miles[/tex]
Given that total distance is 210 miles;
We have that:
[tex]Total Distance = 60\ miles + 50y\ miles[/tex]
[tex]210\ miles = 60\ miles + 50y\ miles[/tex]
Solve for y
[tex]210 - 60 = 50y[/tex]
[tex]150 = 50y[/tex]
[tex]y = \frac{150}{50}[/tex]
[tex]y = 3[/tex]
Hence,
y = 3 hours

solve for x
Answer:
x= 4/5a
Step-by-step explanation:
5=5/ax+1
Step 1: Multiply both sides by a.
5a=a+5x
Step 2: Flip the equation.
a+5x=5a
Step 3: Add -a to both sides.
a+5x+−a=5a+−a
5x=4a
Step 4: Divide both sides by 5.
5x/5=4a/5
x= 4/5a

Which statement could be used to explain why the function h(x) = x3 has an inverse relation that is also a function?
The graph of h(x) passes the vertical line test.
The graph of the inverse of h(x) is a vertical line.
The graph of the inverse of h(x) passes the horizontal line test.
The graph of h(x) passes the horizontal line test.
Answer:
The correct option is;
The graph of h(x) passes the horizontal line test
Step-by-step explanation:
In order to determine if a function has an inverse, and also if the inverse of the function is also a function, the function can be tested by drawing an horizontal line the graph of the function and viewing to find the following conditions;
A graph of a function that is intersected at only one point in all places (vertically) by an horizontal line indicates that the function has an inverse that is also a function, while a graph of a function that is intersected at more than one point in some places (vertically) by an horizontal line indicates that the function does not have an inverse that is also a function.
