Answer:
C. both Vladimir and Robyn
Step-by-step explanation:
Just took the test. Hope this helps
Both Vladimir and Robyn are correct. Then the correct option is C.
What is the equation of a line passing through two points?Suppose the given points are (x₁, y₁) and (x₂, y₂), then the equation of the straight line joining both two points is given by
[tex]\rm (y - y_1) = \left [ \dfrac{y_2 - y_1}{x_2 - x_1} \right ] (x -x_1)[/tex]
Vladimir says that the equation of the line that passes through points (-5, -3) and (10, 9) is y = (4/5) x + 1.
Robyn says that the line passes through the points (-10, -7) and (-15, -11).
Then the equation of the line will be
y + 7 = [(-11 + 7) / (-15 + 10)] (x + 10)
y + 7 = (4/5)x + 8
y = (4/5)x + 1
Both Vladimir and Robyn are correct.
Then the correct option is C.

Answer:
F(x)= 4x
y=4x
now, switch the variables
x= 4y
simplify the equation so that y is by itself. Divide each side by 4
x/4= y
or f(x)= x/4 is the answer
Step-by-step explanation:
Answer:
x/4 = f(x)
Step-by-step explanation:
First you put Y in for f(x)
1. y=4x
Then you flip x and y so you are solving for x
2.x=4y
Now, you divide by 4 to solve

Solve 2(x + 1) = 2x + 5. All real numbers No solution 0 3
Answer: No solution 0=3
Step-by-step explanation:
2(x+1)=2x+5
Step 1: Simplify both sides of the equation.
2(x+1)=2x+5
(2)(x)+(2)(1)=2x+5(Distribute)
2x+2=2x+5
Step 2: Subtract 2x from both sides.
2x+2−2x=2x+5−2x
2=5
Step 3: Subtract 2 from both sides.
2−2=5−2

1) First find the multiplier.
Look at the 0 and 1st term you have 5 as the 0 and 3 as the 1st term.
2)Ask how do we get from 5 to 3?
We subtract 2 so the multiplier is -23)Lets make a linear equation: y=mx +b
m= multiplier or slopex= Just equals x valueb= your starting value or the 0 term which is 54)Use the values that you have to create your equation.
y=-2x +5Note:For the x value just plug in the x value from your table.
Ex.
y=-2(-10)+5y=20+5y=25Determine if the relation is a function. In your handwritten work, explain why or why not.
y = 0.5x - 6
Answer:

Step-by-step explanation:
The relation is a polynomial. Every polynomial is a function, so the relation is a function. (Each value of x produces a single corresponding value of y.)

Rewriting the whole as an Equivalent Fraction
3.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 2 as the denominator :
7 7 • 2
7 = — = —————
1 2
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
3.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
m - (7 • 2) m - 14

When a fraction equals zero
4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
m-14
———— • 2 = 0 • 2
2
Now, on the left hand side, the 2 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
m-14 = 0
Solving a Single Variable Equation:
4.2 Solve : m-14 = 0
Add 14 to both sides of the equation :
m = 14
One solution was found :
m = 14

25(b+3)=11(b-7) using distributive property when solving equations.
Answer:
b = -76/7
Step-by-step explanation:
Step 1: Write equation
25(b + 3) = 11(b - 7)
Step 2: Solve for b
Distribute: 25b + 75 = 11b - 77
Subtract 11b on both sides: 14b + 75 = -77
Subtract 75 on both sides: 14b = -152
Divide both sides by 14: b = -76/7
Step 3: Check
Plug in b to verify it's a solution.
25(-76/7 + 3) = 11(-76/7 - 7)
25(-55/7) = 11(-125/7)
-1375/7 = -1375/7
Answer:
b= -10.85
Step-by-step explanation:
25(b+3)=11(b-7)
25b+75=11b-77
+77 +77
25b+152=11b
-25b -25b
152=-14b
-14 -14
-10.8571=b

A ball is dropped from a height of 25feet and allowed to bounce until it comes to a rest. Each time the ball bounces it rebounds to 4/5 of its previous height
Drag tiles to create an equation you could use to find the height to which the ball rebounds after it hits the floor the third time,h3
H3= ...•... ...
3,4,4/5,25
Answer:
[tex]H3 = 25 * \frac{4}{5} * \frac{4}{5}* \frac{4}{5}[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Height =25[/tex]
[tex]Rebound = \frac{4}{5}[/tex]
Required
Determine the height at the third rebound
At first rebound;
[tex]H1 = 25 * \frac{4}{5}[/tex]
Second rebound
[tex]H2 = 25 * \frac{4}{5}* \frac{4}{5}[/tex]
Third rebound
[tex]H3 = 25 * \frac{4}{5} * \frac{4}{5}* \frac{4}{5}[/tex]
Hence; the equation is:
[tex]H3 = 25 * \frac{4}{5} * \frac{4}{5}* \frac{4}{5}[/tex]
Solving further;
[tex]H3 = 12.8\ ft[/tex]

in order to make some extra money in the summer you water your neighbors lawn and walk their dog.your neighbor pays you $5 each time you walk the dog and $6 each time you water the lawn . when you do both jobs on the same day she gives you an extra $3 , on june 1, you dont have to complete either job, because your neighbor did them bith the day before . if you worked for your neighbor from june 1 to july 20 (thre are 30 days in june and 31 days in july), how many times would you do both jobs on the same day? How much in total would you earn from your neighbor from june 1 to July 20th?
Complete question :
In order to make some extra money in the summer, you water your neighbor's lawn and walk their dog. You water their lawn every 6 days and walk the dog every 4 days. Your neighbor pays you $5 each time you walk the dog and $6 each time you water the lawn.When you do both jobs on the same day. she gives you an exrta $3. On june 1, you dont have ro complete either job, because your neighbor did them both the day before. if you worked for your neighbor from june 1 to july 20 ( there 30 days in june and 31 days in july ), how many times would you do both jobs on the same day ? how much total money would earn?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Watering lawn (L) = $6
Walking a dog (D) = $5
Watering lawn and walking a dog = $(6+5+3) = $14
Lawn is watered every 6 days
Dog is walked every 4 days
Working between June 1 to July 31st:
Last time neighbor did both chores = may 30
how many times would you do both jobs on the same day?
Both jobs were done 4 times on the same day between June 1 to July 30
How much in total would you earn from your neighbor from june 1 to July 20th?
Dog walk = (8 * $5) = $40
Watering lawn = (4 * $6) = $24
Both chores = (4 * $14) = $56
$(40 + 24 + 56) = $120
