what is the slope of a line if the equation is y=7x -5
Answer:
7
Step-by-step explanation:
The standard form is y=mx + b where your m value is the slope and your b value is the y-intercept.
So in your case, 7 is your m value therefore 7 being your slope
Hii!
__________________________________________________________
Answer:
Slope is 7! ^^
Step-by-step explanation:
Note that the equation of the line is given to us in slope intercept, y=mx+c.
m=slope | c=y intercept.
The slope intercept formula is
y=mx+c.
The equation this question provided us is.
y=7x-5
Slope=7

A line passes through the points (1,-6) and (4,3) What is the Y intercept of this line?
Answer: b=-9
Step-by-step explanation:
To find the y-intercept of the line, we can use the points given to make an equation. To find the slope, you use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]m=\frac{3-(-6)}{4-1} =\frac{9}{3} =3[/tex]
Now that we know the slope, we can fill in what we know and solve for y-intercept.
y=3x+b
We can plug in any point to solve for y-intercept.
3=3(4)+b [multiply]
3=12+b [subtract both sides by 12]
b=-9
Now, we know that the y-intercept is b=-9.

Which number is IRRATIONAL?
25.23
8
which number is irrational? 25.23 is irrational because 8 is a rational number.
Answer:
None
Step-by-step explanation:
First let's define the meaning of irrational.
It means "no ratio", which is a number that goes on forever without repeating (e.g. pi and the square root of 2)
25.23 is rational and 8 is also rational.
9x^2 - 16 = (px+t)(px-t) both p and t are constants. Which of the following could be the value of p
Answer:
p = 3
Step-by-step explanation:
9x² - 16 ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b)
Thus
9x² - 16
= (3x)² - 4²
= (3x + 4)(3x - 4)
Compare with (px + t)(px - t)
then p = 3
Point K is on line segment JL. Given JK = 5x + 7, JL = 2x + 8, and
KL= 4, determine the numerical length of JL.
Answer:
The answer to your question is 8.666666666666.
The total numerical length of the segment JL is 6 units.
Given that,
Point K is online segment JL.
JK = 5x + 7,
JL = 2x + 8, and KL= 4
To determine the numerical length of JL.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
For point K on the line segment JL,
JL = JK + KL
from given,
2x + 8 = 5x + 7 + 4
5x -2x = 8 - 11
3x = -3
x = -1
Now,
JL = 2x + 8
JL = 2 * -1 + 8
JL = 6
Thus, the total numerical length of the segment JL is 6 units.

b. Convert 240∘ F to Kelvin K. Round your answer to the nearest hundredth.
240∘F ≈ __ Kelvin
The value of temperature in Kelvin K which has the value 240 degree in Fahrenheit F is 275 K.
How to convert a temperature from Kelvin?The formula to convert a temperature from Kelvin K to Fahrenheit F is,
[tex]F=95(K-273.15)+32[/tex]
Here, K is Kelvin and F is Fahrenheit.
Solve the formula for K in the following way,
[tex]F=95(K-273.15)+32[/tex]
Subtract 32 both side,
[tex]F-32=95(K-273.15)+32-32\\F-32=95(K-273.15)[/tex]
Divide, with 95, both side of equation,
[tex]\dfrac{F-32}{95}=(K-273.15)\\\dfrac{F-32}{95}=K-273.15\\\dfrac{F-32}{95}+273.15=K[/tex]
This is the solved equation for K.
To convert 240∘ F to Kelvin K, put the value in the formula given in above equation,
[tex]\dfrac{F-32}{95}+273.15=K\\\dfrac{240-32}{95}+273.15=K\\\dfrac{208}{95}+273.15=K\\2.12+273.15=K\\275.27=K\\K\approx 275[/tex]
Thus, the value of temperature in Kelvin K which has the value 240 degree in Fahrenheit F is 275 K.

An object is moving at a speed of 2 feet every 8.5 minutes. Express this speed in meters per hour
Answer:
4.30m/hr
Step-by-step explanation:
2 feet/8.5 mins is 0.235294118 feet per minute, which is 4.3030553875397 metres per hour, which to 2 s.f. is 4.30
In meters per hour the speed is 470 meters per hour.
We have an object moving at a speed of 2 feet every 8.5 minutes.
We have to express this speed in meters per hour.
Convert - i). 1 feet to meters 2). 1 minute to hour1 feet = 3.29 meters
1 hour = 60 minutes → 1 minute = [tex]\frac{1}{60}[/tex] hour = 0.017 hr
According to question - We have :
Speed = 2 feet in 8.5 minutes
We know -
1 feet = 3.29 meters
2 feet = 2 x 3.29 = 6.58 meters
and
1 minute = 0.017 hr
8.5 minutes = 8.5 x 0.017 = 0.14 hr
Now -
In 0.014 hr, distance covered = 6.58 meters
In 1 hr, distance covered will be - [tex]\frac{6.58}{0.014}[/tex] = 470 meters/hour
Hence, in meters per hour the speed is 470 meters per hour.

Solve 3x -12 = 24.
Please help!
Answer:
12
Step-by-step explanation:
3x - 12 = 24
Add 12 to both sides to make 3x the subject of the equation.
3x - 12 (+12) = 24 (+12)
3x - 0 = 36
3x = 36
Divide both sides by 3.
3x/3 = 36/3
x = 12
Please give brainliest, rate 5 stars, and thank. Thank you
The required solution to the given equation 3x -12 = 24 is x = 12.
What is the algebraic equation?Algebraic equations are mathematical statements with a minimum of two terms containing variables or numbers that are equal.
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The given equation is given in the question
⇒ 3x - 12 = 24
Add 12 to both sides of the above equation
⇒ 3x - 12 (+12) = 24 (+12)
⇒ 3x - 0 = 36
Apply the subtraction operation,
⇒ 3x = 36
Divide both sides by 3.
⇒ 3x/3 = 36/3
⇒ x = 12
Therefore, the required solution to the given equation 3x -12 = 24 is x = 12.

Suppose that J and K are points on the number line.
If JK = 10 and J lies at -17, where could K be located?
If there is more than one location, separate them with commas.
Answer:
-7, -27
Step-by-step explanation:
J is at -17. K is 10 units from J.
Start at point J, -17:
a) If you go 10 units to the right, you end up at -17 + 10 = -7
b) If you go 10 units to the left, you end up at -17 - 10 = -27
J can be at -7 or at -27

solve for the equation 6x+14=7x+8
Answer:
x = 6
Step-by-step explanation:
For this problem, we simply will isolate the x to find the value of x:
6x + 14 = 7x + 8
6x + -6x + 14 = 7x + -6x + 8
14 = x + 8
14 + -8 = x + 8 + -8
6 = x
Hence, x = 6.
Cheers.
Answer:
x=6
Step-by-step explanation:
First, subtract 6x from both sides to get:
14=x+8
Now, subtract 8 from both sides to get x alone:

2n/5=10, what is the value of 2n-1
Answer:
49
Step-by-step explanation:
First, multiply 5 on both sides:
2n = 50
Then, we divide 2 on both sides:
n = 25
Now we got the value of n, let's calculate 2n - 1.
First, multiply 2 by n so we can get 2n:
2 * 25 = 50
Then, we calculate 50 - 1:
We got 49, and that's the answer ^^
Hope this helps!
The value of 2n-1 is 49 if 2n/5=10, after applying the concept of a linear equation and the value of n is 25.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
2n/5 = 10
2n = 50
n = 25
Plug the value of n in the expression 2n - 1
= 2(25) - 1
= 49
Thus, the value of 2n-1 is 49.

Answer two questions about Equations A and B:
A. 5 = -2(x-1)
B. 5=-2x + 2
1) How can we get Equation B from Equation A?
The value of x for the given equation is -3/2.
The given equation is 5 = -2(x-1).
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Here, 5 = -2(x-1) can be written as 5=-2x + 2.
Now, 5-2=-2x
⇒ 3=-2x
⇒ x=-3/2
Therefore, the value of x for the given equation is -3/2.
