Answers
A slope is also known as the gradient of a line. The correct option is B.
What is Slope?A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.
slope = (y₂-y₁)/(x₂-x₁)
Since for the two functions to be inverse of each other, the line of equations must bisect each other at 90° so that the product of the slope of the two equations is equal to -1.
For the second graph, the slope of the blue line is,
m₁ = (-1-0)/(0-4) = 0.25
The slope of the green line is,
m₂ = (-4-0)/[0-(-1)] = -4
Now, the product of the slope can be written as,
0.25×-4 = -1
Since the product is -1, the function is inverse of each other.
Hence, the correct option is B.

A contractor brought 10.8 ft^2 of sheet metal. She has used 3.7 ft^2 so far and has $127.80 worth of sheet metal remaining. The equation 10.8x-3.7x=127.8 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?
Answers
Answer:
[tex]\$18[/tex]
Step-by-step explanation:
Let the cost of sheet metal per square feet be [tex]x[/tex]
Amount of sheet metal bought is [tex]10.8\ \text{ft}^2[/tex]
Amount of sheet metal used is [tex]3.7\ \text{ft}^2[/tex]
Remaining value of the sheet metal is [tex]\$127.8[/tex]
So we get the equation
[tex]10.8x-3.7x=127.8\\\Rightarrow 7.1x=127.8\\\Rightarrow x=\dfrac{127.8}{7.1}\\\Rightarrow x=18[/tex]
So, cost of sheet metal per square feet is [tex]\$18[/tex].

the fifth term of an arithmetic progression is 40 and the seventh term is 28 more than the 3rd term. Find the first and 10th term.
Answers
Answer:
Step-by-step explanation:
t5 = a + (5-1)d
t5 = a + 4d
40 = a + 4d
t3 = a + 2*d
t7 = a + 2d + 28 = a + 6d
Start with the seventh term which has 2 equal answers
a + 2d + 28 = a + 6d Subtract a from both sides
2d + 28 = 6d Subtract 2d from both sides
28 = 4d Divide by 4
28/4 = d
d = 7
==================
t5 = a + 4d = 40
a + 4*7 = 40
a = 40 - 28
a = 12
===================
First term is 12
10th term is
t10 = 12 + (10 - 1)*7
t10 = 12 + 9*7
t10 = 75

Bill plans to buy school supplies and the following equation represents what he bought.
5x + 20y = 50 is the equation that shows that he spent $50 and bought 5 binders and 20 pencils. Let
X represent the cost of binders and y represent the cost of pencils
1. How much is each binder if each pencil cost $0.50? Explain how you know.
2. How much is each pencil if the binders cost 8 dollars each? Explain how you know.
Answers
Answer:
1. x = 8
2. y = 1/2
Step-by-step explanation:
1. Plug the function
5x + 20(0.50) = 50
= 5x + 10 = 50
Subtract 10 from both side
= 5x = 40
Divide 5 on both sides
= x = 8
2. Plug in the function
5(8) + 20y = 50
= 40 + 20y = 50
Subtract 40 on both sides
= 20y = 10
Divide 20 both sides
= y = 10/20 | 1/2
Answer:
1. 8
Explanation: 5x + 20(.50)=50
5x + 10=50. Now do 50-10 to get 40. So,
5x=40. Now divide 40/5 to get 8.
2. .5
5(8) + 20x=50. Now do 5*8
40 + 20x=50. Now, 50-40 to get
20x=10. And divide 10/20 to get .5

The number expression (-5)⁵/(-5)⁻⁶ can be written as -5¹¹ after using the property of the integer exponent.
What is an integer exponent?In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
We have:
A number expression:
= (-5)⁵/(-5)⁻⁶
As we know from the property of the integer exponent:
[tex]\rm = \dfrac{y^a}{y^b} = y{a-b}[/tex]
y is the base and a, b are the exponent.
As the same base can be written as the sum of the power
In the given number expression there is the same base as -5
Exponent can be subtracted, after subtracting the powers:
= (-5)⁵⁻⁽⁻⁶⁾
= (-5)⁵⁺⁶
= -5¹¹
Thus, the number expression (-5)⁵/(-5)⁻⁶ can be written as -5¹¹ after using the property of the integer exponent.

-7 with a multiplicity of 1 and 3 with a multiplicity of 2
if x = -7
x + 7 is a root
if x = 3
x -3 is a root
Since the multiplicity of this is 2, we have x-3 twice
The complete polynomial is;
(x-3)(x-3)(x+7)
= x^2-6x+9(x + 7)
= x(x^2-6x+9) + 7(x^2-6x+9)
