What is the equation of the line that passes through the points (4,-1 ) and (-7,4 )?
Answer:
[tex] \large{ \tt{❃ \: STEP- BY - STEP \: EXPLANATION}} : [/tex]
Let the equation of line passes through the points A ( 4 , - 1 ) and B ( - 7 , 4 ) . Let A ( 4 , -1 ) be ( x₁ , y₁ ) & B ( - 7 , 4 ) be ( x₂ , y₂ )[tex] \large{ \tt{❁ \: LET'S \: START}} : [/tex]
Using two - point form of the equation of straight line , we have :[tex] \boxed{ \large{ \bf{❀ \: y -y _{1} = \frac{y_{2} - y_{1} }{x_{2} - x_{1}} (x - x_{1)}}}}[/tex]
- Plug the values :
[tex] \large{ \bf{⇢ \: y - ( - 1) = \frac{4 - ( - 1)}{ - 7 - 4}(x - 4) }}[/tex]
[tex] \large{ \bf{⇢y + 1 = \frac{4 + 1}{ - 11} (x - 4)}}[/tex]
[tex] \large{ \bf{⇢ \: y + 1 = - \frac{5}{11} (x - 4)}}[/tex]
[tex] \large{ \bf{⇢y + 1 = - \frac{5}{11}x + \frac{20}{11} }}[/tex]
[tex] \large{ \bf{⇢y + 1 = \frac{ - 5x + 20}{11} }}[/tex]
[tex] \large{ \bf{⇢11(y + 1) = - 5x + 20}}[/tex]

Answer:
D
Step-by-step explanation:
The very first thing you have to realize is that the temperature goes further down the minus scale which means that only A and D can be correct. That's because time in this question is positive.
So if you just try the first value (x = 3), you will get
-3/2 * 3 = -9/2 which would mean that you would add -4 1/2 onto - 10 which is much larger than - 10
A: is not the answer.
-2/3 * 3 - 10 = -6/3 - 10 = -2 - 10 = - 12
That is the answer you should get. The answer is D.

A runner runs a distance of 640 metres in a time of 80 seconds.
What is his average speed?
Answer:
8 meters per second
Step-by-step explanation:
We can divide meters by seconds to get his average speed in meters per second. -- 640 m / 80s = 8 m/sec (meters per second). We can also figure out his average speed in minutes by multiplying 8 by 60 (because there are 60 seconds in a minute), 8 * 60 = 480 m/min (meters per minute).
Answer:
8m/s
Step-by-step explanation:
Speed is equal the distance upon time.
640/80
so speed is equal to 8m/s

Answer:
x = 10
Step-by-step explanation:
We know that in a parallelogram base angles are supplementary angle (add up to 180°)
Given that;
∠U = 9x + 15
∠V = 6x + 15
we can say that:
∠U + ∠V = 180°
(9x + 15) + (6x + 15) = 180
Combining like terms we get;
15x + 30 = 180°
15x = 180 - 30
15x = 150
x = 150/15
x = 10

Answer:
x = 12, x = 7
Step-by-step explanation:
The 2 legs of the triangle are congruent, both 2x + 7, then
2x + 7 + 2x + 7 + x + 11 = 85 ← equation for perimeter
5x + 25 = 85 ( subtract 25 from both sides )
5x = 60 ( divide both sides by 5 )
x = 12
-----------------------------------------------------------
Opposite sides are congruent, then
2(2x) + 2(5x + 3) = 104 ← distribute and simplify both sides
4x + 10x + 6 = 104
14x + 6 = 104 ( subtract 6 from both sides )
14x = 98 ( divide both sides by 14 )
x = 7

(7^(x))^(4)=(7^(2)*7^(3))/(7^(3x))
Answer:
x = 5/7
Step-by-step explanation:
Here, we want to get the value of x
Firstly, according to indices;
(a^m)^n = a^(m * n) = a^mn
Also;
a^m * a*n = a^(m + n)
a^0 = 1 (any number raised to zero as its power is 1)
And lastly;
a^m divided by a^n = a^(m-n)
So using these we can have;
7^4x = 7^( 2 + 3)/7^3x
7^4x = 7^5/7^3x
7^4x = 7^(5-3x)
Since we have the same bases, we have to equate the powers
4x = 5-3x
4x + 3x = 5
7x = 5
x = 5/7

what is the slope of the line that passes through the points (3,-20) and (5,8)?
Answer:
14
Step-by-step explanation:
The equation to find slope is [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]. You plug in the values to get [tex]\frac{8-(-20)}{5-3}[/tex]. This simplifies to [tex]\frac{28}{2}[/tex], which is 14.
While painting the side of his house, Jason positioned his ladder so that the top was 16 feet
above the ground, while the bottom was 12 feet away from the base of the wall. To reach a
spot higher up on the house, Jason moved the ladder so that the top was 18 feet above the
ground. How much closer to the house is the bottom of the ladder now?
The bottom of the ladder is now 96 feet closer to the house compared to its initial position.
To solve this problem, we can use the concept of similar triangles. Let's denote the distance between the bottom of the ladder and the base of the wall as x (in feet). We are given the following information:
Initial ladder position:
Top of the ladder is 16 feet above the ground.
Bottom of the ladder is 12 feet away from the base of the wall.
New ladder position:
Top of the ladder is 18 feet above the ground.
Since the triangles formed by the ladder, the ground, and the wall are similar, we can set up a proportion to find the new distance between the bottom of the ladder and the base of the wall.
Using the initial position of the ladder:
(16 ft) / (x + 12 ft) = (18 ft) / (x)
Cross-multiplying:
16 ft * x = 18 ft * (x + 12 ft)
Expanding:
16x = 18x + 216 ft
Moving the terms involving x to one side:
16x - 18x = 216 ft
Simplifying:
-2x = 216 ft
Dividing by -2:
x = -108 ft
Since distance cannot be negative, we discard the negative solution. The distance between the bottom of the ladder and the base of the wall is 108 ft.
Now, to find how much closer to the house the bottom of the ladder is, we can subtract the initial distance (12 ft) from the new distance (108 ft):
108 ft - 12 ft = 96 ft

two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 5 hours. Together they charged a total of $1600. what are the rate charged per hour by each mechanic. if the sum of the two rates are $215 per hour.
The rate charged per hour by the first mechanic = $105,
And the rate charged per hour by the second mechanic = $110.
Use the concept of ratio defined as:
A ratio indicates how many times one number contains another number. The ratio of two numbers is written as x: y, which is equivalent to x/y.
Where x and y are individual amounts of two quantities.
And, the Total quantity gives after combining as x + y.
Given that,
Two mechanics worked on a car.
The first mechanic worked for 10 hours.
The second mechanic worked for 5 hours.
Together, they charged a total of $1600.
The sum of the two rates charged per hour is $215.
Assume that,
The rate charged per hour by the first mechanic is = x dollars,
The rate charged per hour by the second mechanic is = y dollars.
The first mechanic worked for 10 hours,
The total amount earned by the first mechanic would be 10 times their hourly rate = 10x dollars.
Similarly,
The second mechanic worked for 5 hours,
The total amount earned by the second mechanic would be 5 times their hourly rate = 5y dollars.
Set up two equations based on the given information:
The first equation is the sum of the two rates, which is,
x + y = 215 ......(i)
The second equation is the total amount earned by both mechanics,
10x + 5y = 1600 .....(ii)
Use substitution to find the values of x and y:
From the first equation, we can express x in terms of y as,
x = 215 - y
Substitute this value of x into the second equation:
10(215 - y) + 5y = 1600
Expanding the equation, we get,
2150 - 10y + 5y = 1600
Combining like terms, we have:
-5y = 1600 - 2150
-5y = -550
Dividing both sides of the equation by -5, we get:
y = 110
Now that we have the value of y,
Substitute it back into the first equation to find x:
x + 110 = 215
Subtract 110 from both sides, and we get:
x = 105
Hence,
The rate charged per hour by the first mechanic is $105, & the rate charged per hour by the second mechanic is $110.

If someone vapes for every 15 minutes in a total of 16 hours how many times would they vape in those 16 hours
Answer:
64 times
Step-by-step explanation:
There are 4 sessions of 15 minutes in an hour. Meaning that a person would vape 4 times in an hour. 4 * 16 = 64. A person vapes 64 times in 16 hours. o-o dont vape kids.
Answer and Step-by-step explanation:
We are given the ratio of 1 vape every 15 minutes. We need to convert the time to hours, then multiply the hours by 16.
1 : 15
We know that there are 60 minutes in 1 hour, so we need to multiply 15 by 4 to get 60.
15 × 4 = 60
We also need to multiply 1 by 4, so that the result will be a multiple of the beginning number and so that we didn't get random numbers from somewhere.
1 × 4 = 4
Now we have the ratio 4 : 60, which means that the person vapes 4 times every 60 minutes, or every hour. But since we turned the minutes into an hour, this turns the 60 into a 1. 4 : 1
Now, we have to multiply 4 and 1 by 16 to get the amount of vapes done in 16 hours.
4 × 16 = 64
1 × 16 = 16
So, we have the ratio 64 : 16
This means that the person smokes 64 times in the 16 hours.
