Step-by-step explanation:
Hey there!
The points are; A(-2,3) and B(X,-5). And the distance between them is (√80) units.
We have;
[tex]d = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } [/tex]
Keep all values.
[tex] \sqrt{80} = \sqrt{ {(x + 2)}^{2} + {( - 5 - 3)}^{2} } [/tex]
Squaring on both sides.
[tex] { (\sqrt{80}) }^{2} = ( { \sqrt{( {x + 2)}^{2} + ( { - 8)}^{2} } )}^{2} [/tex]
Simplify them.
[tex]80 = ( {x + 2)}^{2} + 64[/tex]
[tex]( {x + 2)}^{2} = 80 - 64[/tex]
[tex]( {x + 2)}^{2} = 16[/tex]
[tex]( {x + 2)}^{2} = {4}^{2} [/tex]
Cancel square from both sides.
[tex]x + 2 = 4[/tex]
X= 4-2
Therefore, X= 2.
The x-coordinate of B is 2.
Hope it helps....
(80)2=((x+2)2+(−8)2)2
Simplify them.
80 = ( {x + 2)}^{2} + 64
80=(x+2)2+64
( {x + 2)}^{2} = 80 - 64
(x+2)2=80−64
( {x + 2)}^{2} = 16(x+2)2=16
( {x + 2)}^{2} = {4}^{2}
(x+2)2=4^2
Cancel square from both sides.
x + 2 = 4
X= 4-2
Therefore, X= 2.
The x-coordinate of B is 2.

Answers
Answer:
w = - 62.5
Step-by-step explanation:
Given
- 15.6 = - 3.1 + [tex]\frac{w}{5}[/tex] ( add 3.1 to both sides )
- 12.5 = [tex]\frac{w}{5}[/tex] ( multiply both sides by 5 to clear the fraction )

Find the slope of the given relations (2, 5) (2,7) the answer for this pleaee
Answers
Answer: The slope is undefined.
Step-by-step explanation:
The graph of this line is a vertical line, parallel to the y-axis, passing through 2 on the x-axis and includes every real y-value.
Slope is rise/run. The run is the difference in x-values. 2-2=0
Division by 0 is "undefined"
What is the equation for this line? *
O y = -2x +1
O y = 1/2x + 1
O y = -2x - 1
O y = -1/2x + 1
Answers
Answer:
y = -2x + 1
Step-by-step explanation:
The y-intercept is given by the point that is on the y-axis. (1)
This means that the answer contains a +1
Then you must find if the slope is positive or negative
In this case the slope is negative because the line goes "downhill" from left to right
Since the slope is negative it means that there will be a negative sign in the beginning of the equation
Next, to find the slope you need to find the rise over run
Since it is a negative slope the rise will be negative and the run will be positive.
To find the slope find two clear points on the graph such as (0,1) and (2,0)
To find the slope, use the slope formula
This would look like: (0-2)/(1-0)
Your slope will be -2x
Piece it all together and you get a final answer of y= -2x+1

1. Solve the system of equations by substitution:
y = x - 2
4x – 3y = 11
Answers
Answer:
x = 5
y = 3
Step-by-step explanation:
y = x - 2
4x - 3y = 11
substitute y in the second equation with x - 2
4x - 3(x - 2) = 11
open the parenthesis
4x - 3x + 6 = 11
x + 6 = 11
subtract 6 from both sides of the equation
x + 6 - 6 = 11 - 6
x = 5
now substitute x for 5 in the original equation.
y = x - 2
y = 5 - 2
y = 3

Step-by-step explanation:
At a local pumpkin patch you can pick your own pumpkins. There is a $5 charge to enter the patch and then a $0.25 charge per pound of pumpkin. Let p
represent the weight of the pumpkin you choose and C(p)
represent the total cost of the pumpkin in terms of the weight of the pumpkin. Equation, in function notation:
Answers
Answer:
C(p) = 0.25p + 5
Step-by-step explanation:
$5 is the amount of money you have to pay when you don't get a pumpkin (a pumpkin that's 0 lbs), so the y-intercept is 5. 0.25 is the rate at which the price increases as the weight increases, so the slope is 0.25.
m = slope, b = y-intercept
C(p) = mp + b
C(p) = 0.25p + 5

Answer:

2,950
thats the answer
450 is the total interest amount and 2950 is the total amount.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
To find the simple interest, we can use the formula:
A = P(1 + rt)
Now we can simply substitute the values given in the formula.
Before anything, it is a good practice to define the values of each variable.
P = 2,500
r = 9% or 0.09
t = 2
0.09×2500=225
225 is the interest for one year
450 is the total interest for two years.
Now we proceed to use the values in the formula to find total amount.
A=P(1+rt)
A = 2,500(1 + (0.09 × 2))
A = 2,500(1 + 0.18)
A = 2,500( 1.18 )
A = 2,950.00 Rupees
Hence, 450 is the total interest amount and 2950 is the total amount.
