Answer:
D) slope of function A is -2, function B is 4
Step-by-step explanation:
you can see from the equation, y=-2x+1, that the slope (or rate of change) is -2 because it is the coefficient of the 'x' term
to get the slope of Function B we can use the slope formula:
slope = \(\frac{(y-y)}{(x-x)}\)
using points (1,1) and (3,9) we get:
slope = (9-1)/(3-1)
= 8/2 or 4
Which of the following number sentences is an example of the commutative property? Select all that apply.
1.9 × 1 = 1 × 1.9
14.7 + 2.8 = 2.8 + 14.7
2.5 × (3.4 × 1.4) = (2.5 × 3.4) × 1.4
4.5 × 5.5 = 12.375 × 2
(1.9 • 1 = 1 • 1.9; 14.7 + 2.8 = 2.8 + 14.7)
The pharmacist has a 2.8 L bottle of cough syrup. If she fills a bottle that is 1,200 ml, how many ml of cough syrup does the pharmacist have left?
160 ml
400 ml
1,600 ml
4,000 ml
Answer: 1,600 ml
Step-by-step explanation:
You can arrive at this answer by subtracting the amount of cough syrup used (1,200 ml) from the initial amount in the bottle (2.8 L, which is 2,800 ml).
2,800 ml - 1,200 ml = 1,600 ml
I hope this helps :)
Answer: 1,600 mL
Step-by-step explanation:
1. convert the 1,200 mL to L, which is 1.2 L.
2. Subtract that value from 2.8 L, equaling 1.6 L
3. Convert the 1.6 L back into mL by multiplying by 1000, which is equivalent to 1600 mL.
Please answer these two questions! I need this done by 10:40 PM EASTERN STANDERED TIME
Answer:
Look below
Step-by-step explanation:
A. This is a 5-sided figure (pentagon) therefore the interior angles would add up to 540 degrees. We can use this to set up an equation:
x+100+112+113+117=540
Add like terms
x+442=540
Subtract 442 from both sides
x=98
B. This is a 6-sided figure (hexagon) therefore the interior angles would add up to 720 degrees. We can use this to set up an equation:
x+90+90+130+140+150=720
Add like terms
x+600=720
Subtract 600 from both sides
x=120

Step-by-step explanation:
f(5)=3(5)+2. f(5)=17
Answer:
f(5) = 84Step-by-step explanation:
f(x) =3x^2 + 2x - 1
what is f(5)
f(5) = 3(5)² + 2(5) - 1
f(5) = 75 + 10 - 1

Lets start:
Picture 1:-
1. Length of EH= 12cm
2. Angle G= 55 degrees
Picture 2:-
1. Scale factor= 1/4 (I'm not sure about this but this is what I think it is ;-;)
2. Value of y= 28 cm

Well anyways i hope this clears your concepts :D
Answer:
Step-by-step explanation:
EH is 12cm as the shape has been enlarged by scale factor two (all sides have been multiplied by 2).
Angle G remains the same at 55 degrees.
PART A
Scale factor for the triangle = 1/4
Value of y = 28cm
3) z = 5, scale factor = 5

Trying to get this finished before tonight!
Answer:
Step-by-step explanation:
The first step will be to split the area in two separete functions, one to find the rectangle and the other one to find the triangle.
Area of a rectangle A=L*WArea of a triangle A=1/2*B*H (1/2* the length of the base* the length of the height) The area of the rectangle will be A=18*10= 180 The area of the tringle will be A=1/2*8*6= 24 Your answer will be 204 ft^2Answer: 204 Sq. Ft.
Step-by-step explanation:
Length Of Rectangle= 18 Ft.
Breadth Of Rectangle= 10 Ft.
Formula For Area Of Rectangle= Length x Breadth
= 18 x 10 Sq.ft.
=180 Sq. Ft.
Breadth Of Rectangle + Height Of Triangle = 18 Ft.
So, Height Of Triangle = 18 - 10 ft
= 8 Ft.
Base Of Triangle = 6 Ft.
Formula For Triangle Area = \(1/2\) x Base x Height
= 1/2 x 6 x 8 Sq. Ft.
= 24 Sq. Ft.
So, Sum Of Area Of Rectangle And Triangle = 24+ 180 Sq. Ft.
= 204 Sq. Ft. (Answer)

Please I need help Asp please help me solve the equation in the picture below also please show steps on how to solve
Answer:
\(x=-6\dfrac{7}{8}\)
Step-by-step explanation:
\(Solve\:9\:\dfrac{1}{4}\:+\:x\:=\:2\:\dfrac{3}{8}\)
Step 1:
Convert all mixed fractions to improper fractions.
This will make it easier to add and subtract
Mixed fraction \(a\dfrac{b}{c}\) can be converted to an improper fraction using
\(a\dfrac{b}{c}=\dfrac{a\cdot \:c+b}{c}\)
\(9\dfrac{1}{4}=\dfrac{9\cdot 4+1}{4} = \dfrac{37}{4}\)
\(2\dfrac{3}{8}=\dfrac{2\cdot 8+3}{8} =\dfrac{19}{8}\)
Step 2:
Replace every mixed fraction in the original equation with its equivalent improper fraction:
\(\dfrac{37}{4}+x=\dfrac{19}{8}\)
Step 3
Solve for x

I need halp
Answer:
n = 10 and n = 16
Step-by-step explanation:
Using the rules of exponents
\(a^{m}\) × \(a^{n}\) = \(a^{(m+n)}\) , then
\(4^{8}\) × 4² = \(4^{(8+2)}\)
= \(4^{10}\) , thus n = 10
---------------------------------------------
\((a^m)^{n}\) = \(a^{mn}\) , then
\((3^2)^{8}\)
= \(3^{2(8)}\)
= \(3^{16}\) , thus n = 16

show that the (5,5),(5,0),and (0,0) are the vertices of an isosceles triangle.
An isosceles triangle has 2 sides that are equal.
I plotted these points. See attached screenshot.
The first side's distance is 5. You can just count those units along the x axis. (0,0) and (5,0) share the same y coordinate, so the difference in x coordinates is 5-0 = 5.
The next sides's distance is also 5. You can count that distance on the coordinate plane. (5,5) and (5,0) share the same x coordinate, so the difference in y coordinates is 5-0 = 5.
These two sides make a right triangle and are equal length. This is an isosceles right triangle.

I am unsure about number 1, but for number 4, you have to fund the unit rate.
Answer:
Answer for Number 1: 54 1/2
Answer for Number 4: $2.36
Step-by-step explanation:
Explanation for number 1:
1. length x width = area right? So area divided by length = width!
159 3/8 divided by 18 3/4 = 8 1/2
2. width + width + length + length = perimeter right? Now you know the
width, you can do...
8 1/2 + 8 1/2 + 18 3/4 + 18 3/4 = 54 1/2
Explanation for number 4:
1. You know that 4 cup = 1 quart right?
9.44 = 1 quart
2. So you divide it:
9.44 / 4 = $2.36

Solving the Question
We're given:
There were 478 people in total.$1.75 per child$2.25 per adultTotal revenue of $975We must find the number of children and adults who swam.Set variables:Let a represent the number of children who swam.
Let b represent the number of adults who swam.
Create equationsBecause we've set two variables, we need two equations to be able to find the answers.
One of the equations will regard price while the other will regard the number of people, as those are the two things given in the question.
Number of people:
\(a+b=478\)
The number of children + the number of adults = 478 in totalPrice:
\(1.75a+2.25b=975\)
$1.75 per child + $2.25 per child = $975 in totalSolve equations\(a+b=478\)\(1.75a+2.25b=975\)We can solve this question using substitution, where we plug one equation into the other.
Isolate a in the first equation:
\(a+b=478\\a=478-b\)
Plug the first equation into the second equation by replacing a:
\(1.75a+2.25b=975\\1.75(478-b)+2.25b=975\)
Solve for b:
\(1.75(478-b)+2.25b=975\)
⇒ Open up the parentheses:
\(836.5-1.75b+2.25b=975\\836.5-0.5b=975\)
⇒ Subtract 836.5 from both sides to isolate b:
\(-0.5b=138.5\)
⇒ Divide both sides by -0.5:
\(b=277\)
Therefore, there were 277 adults in total.Solve for a:
\(a+b=478\)
⇒ Replace b with 277:
\(a+277=478\\a=201\)
Therefore, there were 201 children in total.Answer
There were 201 children and 277 children at the pool that day.

easy points
why isn't m^3=512 ±8, but just 8? I went onto 2 diff websites and the answer book (yes i have an answer book) and it says 8.
Because of that, when do you add ± in questions like the ones on top? (take into account units and no units, thanks)
i'm confusion
Also, why do you need (x) in questions like (-7)^3? I feel like there is no point, especially when it is just one problem.
Answer: It is only +8 because it is an odd power, so you're only multiplying 3 numbers together and not 2 or 4 and so on. Any odd power is always only going to have 1 answer because if you try the other one then it comes out to be the opposite.
You only need the parenthesis if you want to plug it into a calculator because -7 in a calculator is taken as subtracting 7 while (-7) is taken as a negative 7. They are just building good habits early.
