Answer:

Slope is 2.

Step-by-step explanation:

We can use the points in either order and you will still get the same slope. I usually solve in order that is given. So the first coordinates I label (x1,y1) and the second is (x2,y2).

Slope=m=(y2-y1)/(x2-x1)

m=(9-5)/(3-1)=4/2=2

Answer:

slope = 2

Step-by-step explanation:

use y2-y1 over x2-x1

Answer: P=3 A=7 I think.

Step-by-step explanation:

The perimeter is basically how many sides are there so on this shape there is 3 if u count it and the area is how many squares or whatever is inside the shape so the 11 and 23 stand for the squares on those sides where the numbers are so if u add 11+23=34 so on the last side it only shows u 1 square and has no number so now u have to make the rest of those square till u cant and on the end of it it cant be a square bc its a triangle so it does not have a square like type of shape to where u can make it even. I hope this helps have a nice day or night:)

Step-by-step explanation:

The vertex of an isosceles triangle must be an even number because its identical base angles are congruent. Therefore if the angle at the vertex is x, then the vertex of an isosceles triangle must be an even number because its identical base angles are congruent. Therefore if the angle at the vertex is x, then the .

Step-by-step explanation:

Answer:

d = 67t

and

eqn d = 67t represents d over time.

Step-by-step explanation:

part one : find the hours they have been driving

d = 603 miles driven

r = 67 mph

t = ?

r = d/t

rt = d

t = d/r

t = 603/67

t = 9

unit = in hours

they have been driving for 9 hours.

part 2 : find an equation for the situation that represents distance for any time

t is the independent variable

d will represent the dependent variable

let r represent the slope

d = rt

d = 67t

therefore the eqn d = 67t represents d over time.

Given :

Everyday Isabel swims 10-20 laps in a 50 meter pool.

The amount of time she spends swimming is represented by the function f(x) = 3x .

To Find :

The speed of Isabel.

Solution :

Distance travelled in x laps is, D = 50x .

It is given that time taken is, t = 3x .

So, speed of Isabel is given as :

[tex]Speed=\dfrac{Distance}{Time}\\\\Speed = \dfrac{50x}{3x}\\\\Speed = \dfrac{50}{3}=16.67 \ m/s[/tex]

Hence, this is the required solution.

Given:

The expression is

[tex]\left( 4^{-3} \cdot 2^{-3} \right)^{0} [/tex]

To find:

The Natalie's mistake.

Solution:

We have,

[tex]\left( 4^{-3} \cdot 2^{-3} \right)^{0} [/tex]

Using properties of exponents, we get

[tex]=\left( (4\times 2)^{-3} \right)^{0} [/tex]       [tex][\because a^mb^m=(ab)^m][/tex]

[tex]=\left( (8)^{-3} \right)^{0}[/tex]

[tex]=\left( 8 \right)^{0}[/tex]               [tex][\because (a^m)^n=a^{mn}][/tex]

[tex]=1[/tex]                 [tex][\because a^0=1,\text{ where, a is any non zero number}][/tex]

Therefore, Natalie make a mistake in Step 3. She write [tex]8^0=0[/tex] instead of [tex]8^0=1[/tex].

The area of square ABCD is 10 cm^2 . Show that x^2 + 6x = 1 (requires diagram which I will draw on the whiteboard).

The area of a square is the length of one side squared (multiplied by itself), so for a square with side length 3, the area will be 32 or 3 x 3, which = 9. For a square with side length x, the area will be x2 .Given that the length of one side is 3 + x, the area will be (3+x)2 This can be written as (3+x) * (3+x), and to expand these brackets we will use the 'crab claw' method. We will take the first value in the first bracket, and times it by both values of the second bracket. So we will multiply 3 by 3 which is 9, and then 3 by x which is 3x. We will then take the second value in the first bracket and multiply is by both values in the second bracket. So we will multiply x by 3 which is 3x, and then x by x, which is x2. Now we will add together all the the values we have just found: x2 + 3x + 3x + 9. Because the only like terms are 3x and 3x, and 3x + 3x = 6x, the final equation we form after expanding the brackets will be x2 + 6x + 9.. Given that the area of the square is given as 10cm2, 10 must be equivalent to x2 + 6x + 9, so we form the equation x2 + 6x + 9 = 10. When balancing equations, you must do whatever you do on one side to the other side. Therefore if we take 9 away from the left hand side, we must take 9 away from the right hand side (10 - 9 = 1), leaving us with x2 + 6x = 1, and completing the question.

Answer:

[tex]\lim_{x \to 2^+} f(x)=0[/tex]

Option C is correct option.

Step-by-step explanation:

We are given:

[tex]f(x)=\begin{cases} x^3 , x<2 , \ then \ \lim_{x \to 2^+} f(x)= \\ x-2, x>2\\\end{cases}\\[/tex]

Since the limit given is x-> 2⁺ so, values greater than 2 will be considered. So, we will consider f(x)=x-2 x>2

Putting x=2

f(x)=x-2

f(2)=2-2

f(2)=0

So, [tex]\lim_{x \to 2^+} f(x)=0[/tex]

Option C is correct option.

Answer:

10

Step-by-step explanation:

Given that:

Company A:

40 defective out of every 5000

Company B :

30 out of every 6000

To obtain the highest number of defective phones both companies can produce in common :

Factors of :

40 : 2, 4, 5, 8, 10, 20, 40

30 : 2, 3, 5, 6, 10, 15, 30

Hence, highest number of defective phones both companies can produce in common is 10

Regular division.

It should be 18 because after subtracting 55 and 54 you get 1 but then you bring down the 9 so you get 19. 18 can only fit to 19 one time, 18x 1, and you get 18. So you subtract 18 and 19 and get 1 then you bring down the 3 and get 13.                                                                                                                                                 Answer=18

Step-by-step explanation:

1580-640=940 were local

No. of local fans = 940

Subtraction is one of the four basic arithmetic operations in mathematics. It represents the operation of removing objects from a collection. The minus sign signifies subtraction −.

Example: There are nine oranges arranged as a stack, out of which four oranges are transferred to a basket, then there will be, 9 – 4 oranges left in the stack, i.e. five oranges.

Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5.

Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers such as negative numbers, fractions, rational & irrational numbers, decimals, functions, matrices and vectors.

Given,

Total fans attended championship = 1580

No. of out of state fans = 640

No of local fans = total fans - no. of out of state fans

                          = 1580 - 640

No of local fans = 940

Hence, there were 940 local fans who attended football championship.

Step-by-step explanation:

Based on the information given we can calculate the finance charge of Maryanne’s by simply multiplying her average daily balance which is the amount of $755 times her monthly periodic rate which is 0.0185.

Hence, Maryanne's finance charge is calculated by using this formula

Finance charge=Average daily balance*Monthly periodic rate

Let plug in the formula

Finance charge= $755* 0.0185

Finance charge= $13.97

Therefore Maryanne's finance charge will be $13.97
