Answer:
5
Step-by-step explanation:
Let :
x(1) be 2
y(1) be 5
x(2) be -2
y(2) be 2
We know that distance between any 2 points is equal to:-
[tex] \sqrt{{(x(2) - x(1) )}^{2} + ({y(2) - y(1))}^{2} } [/tex]
So using the above formula ,
[tex] \sqrt{ {( - 2 - 2)}^{2} + {(2 - 5)}^{2} } [/tex]
[tex] = > \sqrt{ {( - 4)}^{2} + {( - 3)}^{2} } [/tex]
[tex] = > \sqrt{16 + 9} [/tex]
[tex] = > \sqrt{25} = 5[/tex]
find the area of the prism
Answer:
total surface area = 400 cm2
Step-by-step explanation:
Seventeen members of Tim's family are going to an amusement park during the week of their family reunion. Adult tickets cost $34 each and child tickets cost $31.50 each. If the total cost for admission to the part is $558, how many adults went to the park? a 7 b 8 c 9 d 10
Answer:
c.
Step-by-step explanation:
Let x be the number of adults in Tim's family. Then (17 - x) is the number of children in Tim's family.
We have $34x + $31.5(17 - x) = $558.
$34x + $31.5(17 - x) = $558
$34x + $535.5 - $31.5x = $558
$2.5x = $22.5
x = 9
Hence the answer is c.
What is the value of x in the equation one-fifthx – two-thirdsy = 30, when y = 15? 4 8 80 200
Answer:
x = 200
Step-by-step explanation:
Given
[tex]\frac{1}{5}[/tex] x - [tex]\frac{2}{3}[/tex] y = 30 ← substitute y = 15 into the equation
[tex]\frac{1}{5}[/tex] x - [tex]\frac{2}{3}[/tex] × 15 = 30 , that is
[tex]\frac{1}{5}[/tex] x - 10 = 30 ( add 10 to both sides )
[tex]\frac{1}{5}[/tex] x = 40 ( multiply both sides by 5 to clear the fraction )
x = 200
The value of x is 200.
Here, given expression is
one-fifthx – two-thirdsy = 30,
We have to find the value of x when y = 15.
What is Mathematical expression?
Mathematical expression is a way where calculations and analytical processes should be observed.
Now, given expression is
⇒ one-fifthx – two-thirdsy = 30,
⇒ [tex]\frac{1}{5} x - \frac{2}{3} y = 30\\[/tex]
When y = 15
⇒ [tex]\frac{1}{5} x - \frac{2}{3} *15 = 30\\\\\frac{1}{5} x -2* 5 = 30\\\\\frac{1}{5} x = 30 + 10\\\\\frac{1}{5} x = 40\\\\x = 200[/tex]
Hence, The value of x is 200.

Point T is on line segment SU. Given ST = 2x + 6, TU = 4, and SU = 4x, determine the numerical length of ST
Step-by-step explanation:
Point T is between Points S and U, where all 3 points are collinear.
Therefore ST + TU must be equal to SU.
(2x + 6) + 4 = 4x
2x + 10 = 4x
2x = 10
x = 5.
Hence, length of ST = 2(5) + 6 = 16.
The length of ST will be 16 units.
What is a line segment ?A line segment is basically a line with two end points.
two or more than two co-linear points is needed to form a line segment.
In the given question
Line segment is SU
Point T is in between point S and point U here all the points are co-linear
SU = ST + TU
4x = (2x + 6) + 4
4x = 2x + 10
2x = 10
x = 5
∴ The length of ST = 2x + 6 = (2×5) + 6 = 16 units

Solve step by step 3(2x-4)=8
Answer:
x = 3.33... or 10/3
Step-by-step explanation:
3(2x - 4) = 8
distribute the 3 into the parentheses
3 • 2x = 6x
3 • -4 = -12
6x - 12 = 8
add 12 to both sides
6x = 20
divide both sides by 6
x = 3.33... or 10/3
Answer: x = 10/3
Step-by-step explanation:
3(2x-4) = 8 apply the distributive property on the left side
6x - 12= 8 Add 12 to both sides
+12 +12
6x = 20 Divide both sides by 6
x= 20/6 which simplifies to 10/3

Answer:
The answer is 25Step-by-step explanation:
f(x) = 3x - 2
h(x) = - 2x² + 3x - 6
First to find f(7/3) substitute the value of x that's 7/3 into f (x)
That's

Write a paragraph proving that x=8 in the equation 7x-28=28
Answer:
[see below]
Step-by-step explanation:
We would need to undo the equation and preform inverse operations to get 'x' on one side. First, we need to get rid of 28 by adding 28 to each side. This would leave us with 7x on one side. Then, we wound divide each side by 7. This would leave us with 'x = 8'. If we plugged in the value, then it would satisfy the equation.
[tex]7x-28=28\\\\7x-28+28=28+28\\\\7x=56\\\\\frac{7x=56}{7}\\\\ \boxed{x=8}[/tex]
Checking the answer:
[tex]7(8)-28=28\\\\56-28=28\\\\\boxed{28=28}[/tex]

Answer:
x=5
Step-by-step explanation:
4x−8=12
Step 1: Add 8 to both sides.
4x−8+8=12+8
4x=20
Step 2: Divide both sides by 4.
4x
4
=
20
4
x=5
Answer:
One solution, x=5.
Step-by-step explanation:
4x-8=12
To find the solution we have to find the value of x.
to find the value of x, we have to add 8 to BOTH sides.
4x-8=12 (Why add 8? because we have to do the opposite of the sign!)
+8 +8
4x=20
Now to find X we have to ISOLATE IT.
So we take out 4, How? We do the opposite to both sides.
4/4 Cancels out
20/4 = 5
So now we know X=5
Insert in the main problem to check.
4(5)-8=12
20-8=12
12=12

x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is the y-intercept.
If we want to know whether a point is a solution to the equation or not, substitute it in the line and check whether both sides of the equation are equal or not.

Given, value of y = 4
To find : Value of x
[tex] \sf{3x - 4y = 65}[/tex]
plug the value of y
