Answer:
r = 3
Step-by-step explanation:
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
Slope 'm' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of a line passing through (4, 2) and (r, -6) is 8.
8 = [tex]\frac{2+6}{4-r}[/tex]
8(4 - r) = 8
4 - r = 1
r = 4 - 1
r = 3

A portion of an amusement park ride is shown. Find EF. Write your answer as a fraction in the simplest form
The point of intersection of two straight line graphs is the point with coordinates that satisfies both lines equations
The length of segment EF is presented as follows;
[tex]EF =\underline{\mathbf{ 17\dfrac{1}{7} \ ft.}}[/tex]
The reason why the above value is correct is as follows;
The given parameters are;
Height of right triangle ACD = 40 ft.
Height of right triangle BCD = 30 ft.
Required:
To find the length of EF
Solution:
The equation of the lines AC and BD are found and equated to find the height of EF as follows;
The slope of AC = [tex]\dfrac{-40}{CD}[/tex]
The equation of AC is presented as follows;
[tex]y - 40 = \dfrac{-40}{CD} \times (x - 0)[/tex]
[tex]y = \dfrac{-40}{CD} \times x + 40[/tex]
The slope of BD = [tex]\dfrac{30}{CD}[/tex]
The equation of BD is given as follows;
[tex]y - 30 = \dfrac{30}{CD} \times (x - CD)[/tex]
[tex]y = \dfrac{30}{CD} \times (x - CD)+ 30[/tex]
Equating both values of y to find the value of y at the intersecting point E, gives;
[tex]\dfrac{-40}{CD} \times x + 40 = \dfrac{30}{CD} \times (x - CD)+ 30[/tex]
Which gives;
[tex]\dfrac{40 \cdot CD - 40 \cdot x}{CD} = \dfrac{30 \cdot x}{CD}[/tex]
Therefore;
40·CD - 40·x = 30·x
[tex]CD = \dfrac{70\cdot x}{40} = \dfrac{7\cdot x}{4}[/tex]
[tex]CD = \dfrac{7\cdot x}{4}[/tex]
Therefore, at E, we have;
[tex]y = EF= \dfrac{40 \cdot CD - 40 \cdot x}{CD} = \dfrac{30 \cdot x}{CD}[/tex]
[tex]y = EF = \dfrac{40 \times \dfrac{7}{4}\cdot x - 40 \cdot x}{\dfrac{7}{4}\cdot x} = \dfrac{30 \cdot x}{\dfrac{7}{4}\cdot x} = \dfrac{120}{7} = 17\dfrac{1}{7}[/tex]
[tex]\underline {EF = 17\dfrac{1}{7} \ ft.}[/tex]

ANSWER ASAP FOR BRAINLIEST
Step-by-step explanation:
Given : x³+y³+z³=k , k from 1 to 100
To Find : x, y, and z
Solution:
This Question can have lot of solutions as constraints are very less
there is no information whether x , y & z are integer
+ ve , Real numbers
k = 1
x= 1 , y = 0 , z = 0
x =0 , y = 1 , z = 0
x = 0 , y = 0 , = 1
k = 2
x= 1 , y = 1 , z = 0
x =0 , y = 1 , z = 1
x = 1 , y = 0 , = 1
k = 3
x= 1 , y = 1 , z = 3
x = 1 , y = 1 , z = 1
x = 1 , y = 0 , = 1
k = 4
x=∛3 , y = 1 , z = 0
x=∛2 , y = ∛2 , z = 0
x=∛2 , y = 1 , z = 1
This way we can have so many solution
Easiest :
x³+y³+z³=k,
x = ∛k , y = 0 , z = 0 will satisfy
A baby giraffe measures 6 feet tall when it is
born, and it grows an average of foot each
month. Write an equation!
Answer:
equation 6+(½×n). n means the number of months
The equation that represents the situation is y = 6 + (1/2)x.
What is linear equation?Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
Given:
A baby giraffe measures 6 feet tall when it is born.
Initial height of baby=6 feet.
Average growth per months = 1/2
=0.5 feet
Let x be the number of months.
And the height of a baby giraffe is y feet.
So equation is,
y = 6+0.5x
or, y = 6 + (1/2)x.
Therefore, the equation is y = 6 + (1/2)x.

At the theater, the Seward family bought 2 adult tickets and 3 children's tickets for $44.50. The Sena family bought 3 adult tickets and 6 children's tickets for $78. Find the price of an adult ticket and the price of a child's ticket.
Answer:
Adult ticket is $7.5 while a child's ticket is $11
Step-by-step explanation:
Given data
Let the cost of an adult ticket be x
and the cost of a child ticket be y
The Seward family
2x+3y= 44.50---------1
The Sena family
3x+6y= 78-------------2
solve 1 and 2
2x+3y= 44.50 X2
3x+6y= 78 X1
4x+6y= 89
- 3x+6y= 78
x+ 0= 11
x= 11
put x= 11 in 1
2x+3y= 44.50
2*11+3y= 44.5
22+3y=44.5
3y= 44.5-22
3y= 22.5
y= 22.5/3
y= 7.5
Hence Adult ticket is $7.5 while a child's ticket is $11

A cylindrical fish tank at the zoo has a capacity of 7252 cubic feet
What is the height of the tank if it’s radius is 16 feet?
The height of the tank if it’s radius is 16 feet is,
⇒ Height = 9.02 feet
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
A cylindrical fish tank at the zoo has a capacity of 7252 cubic feet.
Now, We know that;
Volume of a cylinder = π × radius² x height
Here, Radius is 16 feet.
Hence, We get;
Volume of a cylinder = π × radius² x height
7252 = 3.14 × 16² × h
⇒ 7252 = 803.84 h
⇒ h = 7252 / 803.84
⇒ h = 9.02 feet
Thus, The height of the tank if it’s radius is 16 feet is,
⇒ Height = 9.02 feet

Just simplify both sides of the equation.
1 3/4 + 1/6 + x = 7 1/2 ---> 1 11/12 + x =7 1/2
then subtract the 1 11/12 from both sides
