Step-by-step explanation:
What is the equation of the line that has a slope of -2 and passes through the point (-1, 2)?
Answer:
[tex]{ \bf{y = mx + c}} \\ 2 = ( - 2 \times - 1) + c \\ c = 0 \\ \\ { \boxed{ \bf{y = - 2x}}}[/tex]
Answer:
y = -2x
Step-by-step explanation:
The equation of a line in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -2x +b
Using the point
2 = -2(-1)+b
2 = 2+b
Add -2 to each side
2-2 =b
0=b
y = -2x+0
y = -2x
-2(5x+8)=14+6x step by step
Answer:
x=-15/8
Step-by-step explanation:
Hi there!
We're given the equation -2(5x+8)=14+6x and we need to find the value of x
we do this by isolating the variable so that x is on one side, and everything else is on the other
First, we need to do the distributive property on the left, as the -2 is factored out of 5x+8 and it makes solving for x harder
-2(5x+8)=14+6x
multiply both 5x and 8 by -2
-10x-16=14+6x
add 16 to both sides to clear it from the left side (-16+16=0)
-10x-16=14+6x
+16 +16
_____________
-10x=30+6x
subtract 6x from both sides (6x-6x=0)
-10x=30+6x
-6x -6x
_____________
-16x=30
now, we do have x by itself, but we have -16 attached to it; we need the value of 1x, or x without any coefficient in the front of it
divide both sides by -16
x=30/-16
simplify (divide both sides by -2)
x=-15/8
we can leave it as an improper fraction
Hope this helps! :)
Answer:
x = 15 / 8
Step-by-step explanation:
−2(5x+8) = 14 + 6x
Simplify both sides of the equation.
−2(5x+8) = 14 +6x
(−2)(5x) + (−2)(8) = 14 +6x (Distribute)
−10x +−16 = 14 +6x
−10x −16 = 6x +14
Subtract 6x from both sides.
−10x −16 −6x = 6x + 14 −6x
−16x −16 = 14
Add 16 to both sides.
−16x −16 +16 = 14 + 16
−16x=30
Divide both sides by -16.
-16 x / - 16 = 30/-16
Simplify ( divide RHS side by - 2 )
x = 15 / 8

Suppose a normal distribution has a mean of 48 abd a standard deviation of 5. What is the probability that a data value is between 48 and 52?
Answer:
P(48<x<52) = 0.2881
Step-by-step explanation:
P(48<x<52) = normalcdf(lower,upper,µ,σ) = normalcdf(48,52,48,5) ≈ 0.2881
Therefore, the probability that a data value is between 48 and 52 is 0.2881, or about a 28.81% chance of occurrence.

A teacher is going to assign each student a 3-digit code using the digits 0 through 4. How many codes are possible if no repetitions are allowed?
A.) 60
B.) 125
C.) 24
D.) 64
Answer:
24 codes are possible
Step-by-step explanation:
0 through 4 means we are to select from 0,1, 2 , and 4
That’s a total of 4
The first number has 4 choices, the second 3, the 3rd two and the last 1
The product of the choices are;
4 * 3 * 2 * 1 = 24 codes
What is the gradient of the blue line?
The slope or gradient of the blue line from the given graph is -3.3.
The equation of line is shown in the graph.
What is slope or gradient of a line?The slope or gradient of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope or gradient = Rise/Run
From the given graph, the gradient of a line is
Slope = rise/run
= -4/1.2
= -3.3
Hence, the slope or gradient of the blue line from the given graph is -3.3.

4n + 2 = 6 (1/3n-2/3)
N=???
l give brainiest
Answer:
N= -3
Step-by-step explanation:
4n+2 = 6(1/3n - 2/3)
4n+2 = 2n - 4
2n +2 = -4
2n = -6
n = -3
Answer:
- 3
Step-by-step explanation:
4n + 2 = 6 ( 1 / 3 n - 2 / 3 )
Divide 2 on both sides,
2n + 1 = 3 ( 1 / 3 n - 2 / 3 )
2n + 1 = 3n / 3 - 6 /3
2n + 1 = n - 2
2n - n = - 2 - 1
n = - 3

The profit from a business is described by the function P(x) = -x^2 + 10x - 4, where x is the number of items made, in thousands, and P(x) is the
profit in dollars. How many items will maximize the profit?
A 5,000
B. 10,000
C. 20,000
D. 50,000
Therefore, 5000 items can maximize the profit
The correct answer is an option (a)
What is Profit ?The money that you make when you sell something for more than it cost you.
For given example,
profit is described by the equation :
[tex]P (x) = -x^2 + 10x -4[/tex]
We need to maximize the profit P(x)
[tex]\Rightarrow \frac{d}{dx}P(x)=0\\\\\Rightarrow \frac{d}{dx}( -x^2 + 10x -4 ) =0\\\\\Rightarrow -2x+10=0\\\\\Rightarrow -2x=-10\\\\\Rightarrow x=5[/tex]
since , x is the number of items made in thousand
Therefore, 5000 items can maximize the profit

What is 3,700,000 in scientific notation??
=========================================================
Explanation:
Place a decimal point between the first two digits 3 and 7.
Now ask yourself how you can go from 3.7 back to the original value. Notice we can move the decimal point 6 spots to the right to go from 3.7 back to 3,700,000
Therefore, the exponent over the 10 is 6. The exponent is positive to mean we move the decimal point to the right. If we had a negative exponent, then we'd move left.
You can use a calculator to confirm that 3.7 * 10^6 = 3,700,000

3,700,000 = 3 million, 7 hundred thousand
