Answer: [tex]\frac{-7}{8}[/tex]
Step-by-step explanation:
First, we will need to find the slope of line r.
[tex]\displaystyle \frac{y_{2} -y_{1} }{x_{2} -x_{1}} =\frac{9-1}{8-1}=\frac{8}{7}[/tex]
Next, we know that perpendicular slopes are negative reciprocals of one another. To find the slope of line s, we will find the negative reciprocal of line r's slope.
[tex]\displaystyle \frac{8}{7} \rightarrow \frac{-7}{8}[/tex]
What is the slope of the line that passes through the points (3, -2) and (9, -2)?
a) 0
b) 3
c) -3
d) undefined
Answer:
a) 0
Step-by-step explanation:
the equation of the slope (m) for a line from two points is given as (y2-y1)/(x2-x1)
we are given the points (3,-2) and (9,-2)
we can label the points:
x1=3
y1=-2
x2=9
y2=-2
now substitute into the equation:
m=(-2--2)/(9-3)
simplify
m=(-2+2)/6
m=0/6
m=0
the slope of the line is 0, which is option a

Max and Maggie have to clean the house. It takes Max 9 hours to clean the house, while Maggie can complete the task in 4 hours. Their sister says that it will take 3 hours to complete if they work together. Explain each step in solving this equation, and determine if the sister is correct or not.
Answer:
3 hours
Step-by-step explanation:
Max cleans the house in 12 hours
Max in 1 hour cleans: 1/12 part of the house
Maggie cleans the house in 4 hours
Maggie in 1 hour cleans: 1/4 part of the house
In 1 hour they together do: 1/12 + 1/4 = 1+3/12 = 4/12 = 1/3 work
1 hour===1/3 work
X hours== 1 work
X/3 = 1
X = 3 hours.
Hence, they together complete the work in 3 hours.
And so, the sister is correct.
Hope it helps.
A line, y = mx + b, passes through the point (1, 6) and is parallel to
y = 4x + 6. What is the value of b?
Answer:
Step-by-step explanation:
Let the line to be found be Line 2
Given:
Line 1 :
y = 4x + 6
Since y = mx + b
We can substitute and find that the slope of Line 1 is 4
Therefore slope of Line 2 = (4)
Line 2:
Point - (1,6)
Slope - 4
Therefore: 6 = (4)(1) + b
So equating it we get : b = 2

[tex] \frac{x}{y} + x[/tex]
Answer:
[tex]\frac{x+xy}{y}[/tex]
Step-by-step explanation:
Given
[tex]\frac{x}{y}[/tex] + x
Multiply x by [tex]\frac{y}{y}[/tex] to create a common denominator
= [tex]\frac{x}{y}[/tex] + x × [tex]\frac{y}{y}[/tex]
= [tex]\frac{x}{y}[/tex] + [tex]\frac{xy}{y}[/tex]
= [tex]\frac{x+xy}{y}[/tex]
What is the volume of the composite figure?
Answer:
1428 in³
Step-by-step explanation:
To find the volume of this figure, we will need to use two formulas. The volume of a Rectangular Prism [tex](A=l*w*h)[/tex] and volume of a triangular prism.
[tex](A=\frac{1}{2} (b*h )[/tex]
If we look at the Rectangular Prism, we can find that l = 17, w = 8, and h = 5. Multiply these to find the volume:
17 × 8 × 5 = 680 in³.
Solving for the triangular prism gives us:
A = 1/2 (11 × 8 × 17)
A = 748.
Add these two volumes to find the volume of the composite figure:
748 + 680 = 1428 in³

7. The price of a bike at Store A is 5/6 the price at store B. The price at store A is $150.60. Write and solve an equation to find out how much the bike is at store B. How much did you save by buying the bike at Store A.
As a little tip that's helped me personally when I was taking algebra, making equations for word problems feels a lot easier when you "translate" equations you make into words to make sure that you're using the right equation.
Let's boil down what the question tells us. 5/6 of the price tag of a bike from Store B is the price of a bike from Store A, which is $150.60. Let's use the variable 'b' to represent the price of Store B's bike.
[tex]\frac{5}{6}[/tex] * b = 150.60
Try "translating" the equation above. "5/6 of the price of a Store B bike is equal to 150.60." That seems about right, doesn't it? Let's isolate 'b' so we can get an official answer.
Multiply both sides by 6 to get rid of the denominator:
[tex]\frac{5b}{6}[/tex] * 6 = 150.60 * 6
5b = 903.6
Divide both sides by 5 to get rid of b's coefficient:
[tex]\frac{5b}{5}[/tex] = [tex]\frac{903.6}{5}[/tex]
b = 180.72
The price of a bike from Store B is $180.72

Given the following system of equations: 2x + 3y = 12
2x - 2y = 2
What is the value of x + y?
Answer:
5
Step-by-step explanation:
2x + 3y = 12
2x - 2y = 2 // subtract second equation from first
5y = 10
y = 2
x = (2 + 2y) / 2 = y + 1 = 3
x + y = 5

The area of a rectangle is 325 cm^2. What is the area of a rectangle in cm^2 with
sides 3 times as large?
i’m stuck, pls help
Answer:
2926 cm²
Step-by-step explanation:
The area of a rectangle is 325 cm^2. What is the area of a rectangle in cm^2 with sides 3 times as large?
Step 1
A rectangle has both Length and Width
Let us assume the Length = Width
The area of a rectangle is 325 cm²
Area = Length × Width
325 cm² = L²
L = √325 cm²
L = 18.027756377 cm
Approximately = 18.03 cm = Widtdh
Step 2
What is the area of a rectangle in cm² with sides 3 times as large?
From Step 1
L = 18.03cm
3 times as large = 18.03 cm × 3
= 54.09 cm
The Area for this rectangle
= A = L²
A =( 54.09 cm)²
A= 2925.7281 cm²
Approximately = 2926 cm²
Which value of "X" is a solution to this equation?
4x2 +22x +10
Answer:
Two solutions: X = -5 and X = -0.5

2x^2 + 11x + 5 = 0
delta = 11^2 - 4 * 2 * 5 = 121 - 40 = 81

Akiko is making a pizza. The radius of the pizza is 19 inches. What is the circumference of the pizza (use 3.14 for pi and round to nearest tenth)?
Answer:
≈119.3
Step-by-step explanation:
The area for circumference is as follows:
[tex]C = 2\pi r\\or\\C = d\pi[/tex]
The above equations mean the same thing, because the diameter is just 2 times the radius.
Anyhow, we insert this value into the equation...
[tex]C = 2\pi(19)\\C = 38(3.14)\\C = 119.32\\[/tex]
This rounds to:
≈119.3

Answer:
B
Step-by-step explanation:
just use pyth then you'll get the answer
Answer:
B
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
let h be the hypotenuse, then
h² = 6² + 18² = 36 + 324 = 360 ( take the square root of both sides )
h = [tex]\sqrt{360}[/tex]
= [tex]\sqrt{36(10)}[/tex]
= [tex]\sqrt{36}[/tex] × [tex]\sqrt{10}[/tex]
= 6[tex]\sqrt{10}[/tex] → B
