Point V is the midpoint of line MP.
If VP = 4x – 6, and MP = 6x + 2.
Find the length of line MP.
Answer:
44
Step-by-step explanation:
1. Since point V is the midpoint of line MP, VP is half of MP.
2. Since VP is half of MP, 2(4x-6) = 6x+2
3. [tex]\frac{2(4x-6)}{2} =\frac{6x+2}{2}[/tex]
4. 4x-6 = 3x+1
5. x = 7
6. Substitute x with 7 on equation 6x+2. 6(7)+2
7. Answer 44.
A dealer paid kshs 240,000 to an agent as commission for sale of a car .The commission was 3 percent of the car price how much money did the dealer remain with from the sale of the car if he also had to pay the government v.A.T at 16 percent of the total car
Answer:
kshs 6,480,000
Step-by-step explanation:
Since, kshs 240,000 represent the 3% of the car price, you can use a rule of three to calculate the amount that represents 100%:
240,000 → 3%
x → 100%
x=(240,000*100)/3
x=8,000,000
So, the price of the car is kshs 8,000,000 and you can calculate the 16% of this, to find the amount that the dealer had to pay as government V.A.T:
8,000,000*16%=1.280.000
Now, you can subtract the comission and the government VAT from the car price:
8,000,000-240,000-1,280,000=6,480,000
According to this, the answer is that the dealer remained with kshs 6,480,000 from the sale of the car.
the table shows ordered peirs of the function y= 8 - 2x what is the value of y when x = 8
Answer:
y = -8
Step-by-step explanation:
All we need to is substitute for x and solve for y.
y = 8 - 2x
y = 8 - 2(8)
y = 8 - 16
y = -8

Answer: D
Step-by-step explanation:
Answer:
C=6.4ft
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + 5^2 = c^2
4 + 4 = 16
5 + 5 = 25
16 + 25 = c^2
41 = c^2
Now you will need to find the square root of 41 which gives you 6.40 and you just round to nearest tenth..

A turtle traveled
1/10 miles in 1/2 hour. What was the turtle's rate in miles per hour?
A: 1/20
B: 1/12
C: 1/6
D: 1/5
The turtle's rate in miles per hour is 1/5 miles/hr.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that a turtle traveled 1/10 miles in 1/2 hour.
Rate is defined as the distance travelled in a unit hour {1 hour}.{R} = x/t.We can write the rate as -
{R} = (1/10)/(1/2)
{R} = (1/10) x 2
{R} = 1/5 miles/hr
Therefore, the turtle's rate in miles per hour is 1/5 miles/hr.

2) Explain what Karla did in each step of his work.
3) Are Pablo and Karla correct?
Please help due today!!
Answer:
Pablo Used the Commutative property to Reorder the terms. Pablo then Combined all his like terms. Pablo then Divided 21 by 3x to get 3(7+x). Pablo then subtracted 7 from 13. He got x = 6
Pablo did his math wrong.
Karla Did her work correctly. Karla used the commutative property to reorder the terms. She then combined her like terms. She subtracted 21 from itself and 39, leaving 3x and 18 on different sides of the equal sign. She divided 3x by 3 which equals x and 18 by 3 which equals Karla is correct.

Write an equation of a line that has a slope of 1/2 and has a point at (2, 5).
The graph shows the amount of money paid when purchasing bags of peanuts at the zoo:
A graph is shown. The x-axis is labeled from 0 to 9. The y-axis is labeled from 0 to 13. The four points shown on the graph are ordered pairs 0, 0 and 1, 4 and 2, 8 and 3, 12. These points are joined by a line. The label on the x-axis is Bags of peanuts. The title on the y-axis is Total cost in dollars.
Write an equation to represent the relationship between the total cost (y) and the number of bags of peanuts (x).
y = 4x
y = one-fourth x
y = 3x
y = one-third x
Answer:
dive the cost by the number of bags for each dot:
4 / 1 = 4
8 / 2 = 4
12 / 3 = 4
This means each bag cost $4
The equation would be Y = 4X, because you would multiply each bag bought (X) by $4 to get the total cost (Y).

Which is the graph of the line LaTeX: y-2=3\left(x-1\right)y − 2 = 3 ( x − 1 )?
Answer:
D.
Step-by-step explanation:
The equation given takes the point-slope form which is, [tex] y - b = m(x - a) [/tex]. Where,
(a, b) = (x, y) coordinates of a point on the line.
m = slope of the line .
To find which graph has a line equation of [tex] y - 2 = 3(x - 1) [/tex], look for the points which will give you something almost exactly as the equation if you substitute their values into [tex] y - b = m(x - a) [/tex].
Let's consider option D.
We have a given point (1, 2). a = 1, b = 2.
Substitute these into [tex] y - b = m(x - a) [/tex]
We have:
[tex] y - (2) = m(x - (1)) [/tex]
[tex] y - 2 = m(x - 1) [/tex]
As you can see, this looks almost exactly as
[tex] y - 2 = 3(x - 1) [/tex].
If you want to be certain that option D is the answer, find m by using the coordinates of any other point on the line and plug into [tex] y - 2 = m(x - 1) [/tex] to find m:
In graph D, let's take the points (0, -1)
[tex] -1 - 2 = m(0 - 1) [/tex]
[tex] -3 = m(-1) [/tex]
[tex] -3 = -m [/tex]
Divide both sides by -1
3 = m
m = 3.
Therefore, option D is the graph of the line [tex] y - 2 = 3(x - 1) [/tex].

The Allied Taxi Company charges $2.50 to pick up a passenger and then adds $1.95 per mile. Isaac was charged $27.46 to go from one city to another. If x represents the number of miles driven by the taxi, which linear equation can be used to solve this problem, and how many miles did Isaac travel, rounded to the nearest tenth? 1.95x + 2.50 = 27.46; Isaac traveled 15.4 miles. 1.95x + 2.50 = 27.46; Isaac traveled 12.8 miles. 2.50x + 1.95 = 27.46; Isaac traveled 11.8 miles. 2.50x + 1.95 = 27.46; Isaac traveled 10.2 miles.
Answer:
B. 1.95x + 2.50 = 27.46; Isaac traveled 12.8 miles.
Step-by-step explanation:
If x represents the number of miles driven by the taxi
Then, amount charged= $ (2.50+1.95x)
Isaac was charged $27.46
2.50+1.95x = 27.46
Subtracting both sides by 2.50, we get
1.95x= 24.96
Dividing both sides by 1.95, we get
x=12.8
The linear equation will be 1.95x + 2.50 = 27.46
Amount charged to pick up passenger = $2.50 to pick up a passenger
Amount charged per mile = $1.95 per mile
Since Isaac was charged $27.46, then the equation will be:
2.50 + 1.95(x) = 27.46
2.50 + 1.95x = 27.46
Therefore, the linear equation will be 1.95x + 2.50 = 27.46
