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]

When using substitution, what does the equation look like after the 1st step ?
y = 6x +3
x + 2y = 5
Answer:
Step-by-step explanation:
y = 6x + 3 --------------(I)
x + 2y = 5 -------------(II)
substitute y = 6x + 3 in equation (II)
x + 2*(6x + 3) = 5
x + 2*6x + 2*3 = 5
x + 12x + 6 = 5
13x + 6 = 5

1. 1 3/4 + 1/6 + ____ = 7 1/2
2. 8 4/5 - 2/3 - _____ = 3/ 1/10
Answer:
6 5/12 and 5 1/30
Step-by-step explanation:
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
x = 6 5/12

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.
