Answer:
36.25 units
Step-by-step explanation:
Hi there!
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] where two endpoints are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points (19,−8) and (−14,−23):
[tex]d=\sqrt{(19-(-14))^2+(-8-(-23))^2}\\d=\sqrt{(19+14)^2+(-8+23)^2}\\d=\sqrt{(33)^2+(15)^2}\\d=\sqrt{1089+225}\\d=\sqrt{1314}\\d=36.25[/tex]
Therefore, the distance between the points is approximately 36.25 units.
I hope this helps!
Answer:36.25
Step-by-step explanation:distance between (x1, y1) and (x2,y2) is square root of (x2-x1)^2 + (y2-y1)^2. think of graph the distance between two points is the hypotenuse of a right angle triangle where the height is the difference of y and base is the difference of x
= square root of (19+14)^2 +(-23+8)^2= 36.25
8+(2+6)=(8+2)+6 what property justifies that statement
Answer:
Associative Property of Addition
Step-by-step explanation:
According to the Associative Property of Addition, when three real numbers are added, it makes no difference which two are added first.
(a + b) + c = a + (b + c)
Therefore, 8 + (2 + 6) = (8 + 2) + 6 is an example of the Associative Property of Addition.

Answer:
$21
Step-by-step explanation:
Let the amount Lori bought the shirt and the hat be $x, if she bought them at half off sale, the initial price of both item will be 2 × $x
If she spent $21 on both items, the initial price will have been 2 x $21 = $42 where x is $21
Original price of the hat and shirt is therefore $42. Since both are on half off sale, the initial price is the hat will be $42/2 = $21
Write
2^

in surd form.
Answer:
[tex] {2}^{ \frac{3}{2} } = \sqrt[3]{ {2}^{2} }\\= \sqrt[3]{ {4}}[/tex]
The surd form is : [tex](\sqrt{2} )^3[/tex]
[tex](\sqrt{2} )^3=\sqrt{2}. \sqrt{2}. \sqrt{2}[/tex]
It gives in the approximate value is : 2.80
What is surd form?Surds are the square roots (√) of numbers that cannot be simplified into a whole or rational number. It cannot be accurately represented in a fraction. In other words, a surd is a root of the whole number that has an irrational value. Consider an example, √2 ≈ 1.414213. It is more accurate if we leave it as a surd √2.
We have from the question is:
Write in the surd form:
=> [tex]2^\frac{3}{2}[/tex]
Now, According to the definition:
Write like this:
[tex]2^\frac{3}{2}=((\sqrt{2} )^2)^\frac{3}{2}[/tex]
Cancel out the:
2 × 3/2 = 3
So, [tex](\sqrt{2} )^3=\sqrt{2}. \sqrt{2}. \sqrt{2}[/tex]
It gives in the approximate value is : 2.80
But, The surd form is : [tex](\sqrt{2} )^3[/tex]

Graph the solution to this system of inequalities in the coordinate plane.
3y > 2x + 12
2x + y< -5
Answer:
The vertices of both where they cross show (-4,1)
Step-by-step explanation:
3y > 2x + 12
x < 3(y - 4) / 2
y > 2 (x + 6) / 2
2x + y< -5
= x> -5
set = together
x < 3(y - 4) / 2 shows dotted ascending line attached through x=-6
This means x=--6 y = 0
x>-5 shows boundary dotted vertical line through -5
this means x = -5 y = 0
If it had been x ≥ -5 it would have been solid boundary line.
The area within the dotted lines create a right angle triangle where the far left angle shows ascends to (-6, 0) and crosses y at 0,4 however the shaded area will not got hat far and stop at -4,0 and the area below.
As seen attached when both are plotted with dash dotted boundary lines.
The vertices of both show (-5,1)
Sally is 3 years older than Jill was 5 years ago. Write an algebraic expression for both of their ages. If Jill is 10, how old is Sally?
Answer: 13 (and Sally will always be 3 years older than Jill)
Step-by-step explanation:
Let S and J stand for Sally and Jill's ages. We are told:
(S-5) = (J-5)+3 [Sally is 3 years older than Jill was 5 years ago] The 5 years ago is the reason for the (S-5) and (J-5) expressions.If Jill is 10, how old is Sally?
(S-5) = (J-5)+3
(S-5) = (10-5)+3
S-5 = 8
S = 13
We actually don't really need an equation for solving this, other than the question asks us to write one. It doesn't matter how many years later, since Sally is 3 years older, she will always remain 3 years older, if we ignore the likelihood that the statement doesn't hold true for the period between their actual birthdays.

Step-by-step explanation:
Write down in terms of n, an expression for the nth term
of the following sequence
-8 -15 -22 -29 -36
Answer:
[tex]a_{n}[/tex] = - 7n - 1
Step-by-step explanation:
There is a common difference between consecutive terms , that is
- 15 - (- 8) = - 22 - (- 15) = - 29 - (- 22) = - 36 - (- 29) = - 7
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 8 and d = - 7 , then
[tex]a_{n}[/tex] = - 8 - 7(n - 1) = - 8 - 7n + 7 = - 7n - 1

find the other angle of W first.
to do that, take 180 - 64
that makes angle W 116
add angle W and angle Y

You spin the spinner and flip a coin. Find the probability of the compound event.
A spinner is divided into 5 equal regions. The sections are labeled 1, 2, 3, 4, and 5.
The probability of spinning a prime number and not flipping heads is
.
3/10
2, 3, and 4 are prime numbers. Those are three numbers worth. The maximum number on the spinner is 5 so you multiply 5 by 2 and get 10. Again, 3 numbers are prime numbers. So from there you add 3 and 10 as a fraction and get 3/10

using the graph, determine the coordinates of the roots of the parabola
Answer:
(-1, 4)
Step-by-step explanation:
Use of the coordinate plane.
The vertex of the parabola is 1 to the left and up 4.
Think of the vertex as where the curve starts.
Answer:
-3 and 1
Step-by-step explanation:
Hello!
The roots of the parabola are the intersections of the graph and the x-axis (y = 0).
Since the graph's vertex is above the x-axis and opens down, the graph has two roots.
The points of intersection are:
[tex](-3,0)[/tex][tex](1,0)[/tex]Therefore, the roots of the parabola are -3 and 1.

Answer:
C
Step-by-step explanation:
ley y = f(x) and rearrange making x the subject
y = [tex]\frac{1}{x+5}[/tex] - 1 ( add 1 to both sides )
y + 1 = [tex]\frac{1}{x+5}[/tex] ( multiply both sides by (x + 5)
(y + 1)(x + 5) = 1 ← expand factors using FOIL
xy + 5y + x + 5 = 1 , that is
xy + x + 5y + 5 = 1 ( factor first/second and third/fourth terms on left side )
x(y + 1) + 5(y + 1) = 1 ← factor out (y + 1) from each term on left side
(y + 1)(x + 5) = 1 ( divide both sides by (y + 1) )
x + 5 = [tex]\frac{1}{y+1}[/tex] ( subtract 5 from both sides )
x = [tex]\frac{1}{y+1}[/tex] - 5
Change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then
[tex]f^{-1}[/tex] (x) = [tex]\frac{1}{x+1}[/tex] - 5 where x ≠ - 1

Which function passes through the points (2,3) and (4,4)
Answer:
y = 1/2x + 2
Step-by-step explanation:
First, we find the slope of the line by subtracting the x- and y-values of each point, and dividing that:
(4-3)/(4-2) = 1/2
So, our slope is 1/2. Then, we insert this into a y = mx + b equation using one of our points to find the y-intercept (b). I used the point (2, 3):
3 = 1/2(2) + b
3 = 1 + b
b = 2
Now that we have our slope and the y-intercept, we can create a function: y = 1/2x + 2.
Answer:
C, Because if you draw a graph, the line y=1/2x+2 lines up with (2,3) and (4,4),
Divide this polynomial:)

The edges on Zachary's snowboard are chlpped and dented from riding over rocks, so Zachary wants to buy a new one. He can't afford the board he wants, so he opens a hot chocolate stand near his house. Zachary figures out how many cups of hot chocolate he must sell to have enough money for the snowboard. One cold, snowy Saturday, Zachary sells 43 cups of hot chocolate. Now, he needs to sell 47 more cups to buy the snowboard. Which equation can you use to find the total number of cups c Zachary must sell to buy the snowboard?
Answer:
c-43=47
Step-by-step explanation:
Well this is kinda obvious.
He already sold 43 cups of hot choclate and he needed 47 more.
So the total amount of cups is (c) so we can make an equation like this
c-43 (since theres total which is unknown so ”c” and then Theres the already sold 43 cups).
c-43=47 (the 47 is the amount he needs to sell)
So final equation to determine total cups needed
c-43=47

Answer: Solution In Photo
Answer:
D) y = -2x - 4Step-by-step explanation:
Use the points:
(-2, 0) and (0, -4)The y- intercept is - 4 and the slope is:
m = (-4 - 0)/(0 - (-2)) = -2The line is:
y = -2x - 4Correct choice is D
5. Which point lies on the line: y - 4 = -3(x + 2)?
Answer:
(- 2, 4 )
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 4 = - 3(x + 2) ← is in point- slope form
