-4x=32
Answer:
X=-8
Step-by-step explanation:
-4(-8)=32
Answer:
X = -8
Step-by-step explanation:
First, you need to understand to "do the opposite" in both sides of your equation. In this problem, -4 is being multiplied by x. To get x by itself, we must do the opposite, which means dividing both sides by -4 in this problem.
Next, you need to understand how the negative in the -4 will affect your answer. When dividing a positive number by a negative number, the resulting answer will be negative.
Finally, just put all your steps together! Divide both sides by -4, giving you x = 8. Then, apply the negative from the 4 and you'll get a final answer of x = -8! Hope this helps!

Answer:
923×10‐⁵
please mark brainlist
Answer:
9.23 x 10^-5
Step-by-step explanation:
To set up scientific notation you need to move the decimal point so there is a one digit other than zero in the first part (9.23). To do this you move the decimal point to the right 5 digits, accounting for the negative 5 (10^-5).
It's negative cause it's going right, if it was moving left it would be positive.

If (-3,1) is in the function f(x), then which of the following
points will be in the function f-'(x)?
(1, -3)
(3,-1)
(-1,3)
(-1,-3)
The point which will be in function is f-'(x) is (1, -3).
We are given that;
The point (-3,1) is in the function f(x)
Now,
Function is a type of relation, or rule, that maps one input to specific single output.
A function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
To find the inverse of a function, we need to switch the inputs and outputs of the function.
In other words, if f(x) = y, then f^ {-1} (y) = x.
This means that if (-3, 1) is in the function f(x), then (1, -3) will be in the function f^ {-1} (x).
Therefore, by function answer will be (1, -3).

Answer:
aₙ = 3n + 9Step-by-step explanation:
[tex]a_1=12\\a_2=15\\\\d=a_2-a_1=15-12=3\\\\a_n=a_1+d(n-1)\\\\a_n=12+3(n-1)\\a_n=12+3n-3\\a_n=3n+9[/tex]
Equation of the nth term of the given arithmetic sequence is equals to

What is arithmetic sequence?
" Arithmetic sequence is a sequence in which difference between two consecutive terms remain constant. "
Formula used
nth term in Arithmetic sequence
aₙ = a₁ + (n -1)d
Where
aₙ=nth term of the sequence
a₁ = first term of the sequence
n = number of terms
d = common difference
According to the question,
Given arithmetic sequence is
12, 15, 18, 21, ......
a₁ = 12
d = 15 - 12
= 3
Substitute the values in the formula of nth term we have,
aₙ = 12 + (n - 1) 3
⇒ aₙ= 12 + 3n -3
⇒ aₙ= 3n +9
Hence, equation of the nth term of the given arithmetic sequence is equals to aₙ = 3n +9.

Answer: see below
Step-by-step explanation:
Slope-Intercept form is: y = mx + b where
m is the slopeb is the y-intercept1) 2x + y = 2
y = -2x + 2 Subtracted 2x from both sides
↓ ↓
m= -2 b= 2
Slope (m) = -2 y-intercept (b) = 2 Equation: y = -2x + 2
2) 4x + y = -5
y = -4x - 5 Subtracted 4x from both sides
↓ ↓
m= -4 b= -5
Slope (m) = -4 y-intercept (b) = -5 Equation: y = -4x - 5
3) 4x + 2y = 6
2y = -4x + 6 Subtracted 4x from both sides
y = -2x + 3 Divided 2 from both sides
↓ ↓
m= -2 b= 3
Slope (m) = -2 y-intercept (b) = 3 Equation: y = -2x + 3
4) -6x + 3y = -9
3y = 6x - 9 Added 6x to both sides
y = 2x - 3 Divided 3 from both sides
↓ ↓
m= 2 b= -3
Slope (m) = 2 y-intercept (b) = -3 Equation: y = 2x - 3
5) x + 3y = 6
3y = -x + 6 Subtracted x from both sides
y = (-1/3)x + 2 Divided 3 from both sides
↓ ↓
m= -1/3 b= 2
Slope (m) = -1/3 y-intercept (b) = 2 Equation: y = (-1/3)x + 2
Solve the literal equation |ax+b| = c for a
Answer:
Since we're dealing with absolute value we'll have two answers.
a= c/x-b/x
a= -c/x-b/x
Step-by-step explanation:
Since we can't combine any values inside the absolute value signs we get rid of the absolute value signs.
Now we have: ax+b=c
since we're trying to get a by itself, we subtract the b to get ax= c-b
Now we divide the x and since we can't directly put it with a single value on the right side, we have to put it with both the c and b. Now we have a=c/x-b/x.
For the second answer, you first put a negative with the c. ax+b= -c
Now you solve exactly the same way you did above.
Hope this helps! :)

Winston has just received his monthly credit card statement. He placed 7 charges on his card in the last month with a mean of $34.00 per charge. He knows that 6 of the charges were as follows: $33.78,$34.24,$35.59,$29.88,$36.58,$26.78 Determine the amount of the 7th charge.
Answer:
$41.15
Step-by-step explanation:
Given That :
Data for 6 charges :
$33.78,$34.24,$35.59,$29.88,$36.58,$26.78
Total number of charges = 7
Mean value for the 7 charges = $34.00
Amount of the 7th charge :
Let amount = c
(33.78 + 34.24 + 35.59 + 29.88 + 36.58 + 26.78 + c) / 7 = 34.00
= (196.85 + c) / 7 = 34
196.85 + c = 34 * 7
196.85 + c = 238
c = 238 - 196.85
c = $41.15
The amount of the 7th charge is $41.15
Given That :
Data for 6 charges: $33.78, $34.24, $35.59, $29.88, $36.58, $26.78.
Total number of charges = 7
Mean value for the 7 charges = $34.00
Amount of the 7th charge :
Let amount = c
So,
[tex]\frac{\left(33.78+34.24+35.59+29.88+36.58+26.78+c\right)}{7}=34.00\\\frac{(196.85+c)}{7} = 34\\196.85 + c = 34 * 7\\196.85 + c = 238\\c = 238 - 196.85\\c = $41.15[/tex]

Let cot(x) = 5/8, with 0 < x < 90. What is sin(x)?
Answer:
8 / √89
Step-by-step explanation:
1. cot (x) = 5/8
2. 8√89 / 89
3. simplify
4. 8 / √89
Value of sin(x) is equals to (8√89) / (89), 0 < x < 90.
What are trigonometric functions?" Trigonometric functions are mathematical functions which relates angles and sides of a right angle triangle , where 0 < x < 90°."
Formula used
In right angled triangle ABC , ∠B = 90° , ∠C = x°
cot (x )= ( Base ) / ( Opposite side)
sin ( x) = ( Opposite side ) / ( Base )
Pythagoras theorem
(Hypotenuse)² = (Base)² + (Opposite side)²
(AC)² = (AB)² + (BC)²
According to the question,
Given
cot (x) =5 / 8 , 0< x< 90
Therefore, by comparing the given values of trigonometric function with the formula we have,
Base = 5
Opposite side = 8
Substitute the value in the Pythagoras theorem we get,
(Hypotenuse)² = 5² + 8²
⇒ (Hypotenuse)² = 25 + 64
⇒ Hypotenuse = √89
Therefore,
sin(x) = 8 / √89
= 8√89 / 89 ( rationalize √89)
Hence, value of sin(x) is equals to (8√89) / (89), 0 < x < 90.
