6-7x= 7x- 9x - 4
The value of x is _.
Answer:
x = 2
Step-by-step explanation:
Step 1: Write equation
6 - 7x = 7x - 9x - 4
Step 2: Solve for x
Combine like terms: 6 - 7x = -2x - 4Add 7x to both sides: 6 = 5x - 4Add 4 to both sides: 10 = 5xDivide both sides by 5: 2 = xRewrite x = 2Step 3: Check
Plug in x to verify it's a solution.
6 - 7(2) = 7(2) - 9(2) - 4
6 - 14 = 14 - 18 - 4
-8 = -4 - 4
-8 = -8
Jenny is solving the equation 3 x + 5 = 4 x + 2 using algebra tiles. She cannot decide if she should add 3 negative x-tiles or add 2 negative unit tiles to both sides first. Which explains which Jenny should do first?
A.She should add 3 negative x-tiles first because that is the only way to isolate the variable.
B.She should add 2 negative unit tiles first because that is the only way to get to the correct solution.
C.She can do either one first because zero pairs will be created to isolate the variable either way.
D.She should do neither one first because the first step is to add 4 negative tiles to both sides.

A function takes an input of a whole number and if the number is less than 10, multiplies it by 5. If the input number is greater than or equal to 10, subtracts 5 from the input. If I input the numbers 8 and 14 into the function, what outputs should I expect to return?
Answer:
When you input 8, the output will be 40
When you input 14, the output will be 9
Step-by-step explanation:
let the function = fn
If fn < 10, then output = 5(fn)
If fn ≥ 10, then, Output = fn - 5
When you input 8 ( 8 is less than 10, then multiply by 5)
fn = 8 and 8 < 10
Output = 5(fn)
Output = 5 x 8
Output = 40
When you input 14 ( 14 is greater than 10, then subtract 5 from the input)
Output = fn - 5
Output = 14 - 5
Output = 9

need help to find the Value of X
Answer:
83
Step-by-step explanation:
All sides of a triangle combined equal 180 so you would add the values you have and then subtract it from 180
Step-by-step explanation:
We know that:-
All angles of a triangle sum up to give 180°.
So, According to Question,
[tex]20 + 87 + x = 180[/tex]
[tex]107 + x = 180[/tex]
[tex]x = 180 - 107[/tex]
[tex]x = 73[/tex]
So, x = 73° is the answer.

Please help on this: Given: 4c-d = f, d = c-e, f = d + e; Prove: 3c = d
Answer:
Step-by-step explanation:
Given the equations:
4c-d = f ....... 1
d = c-e....... 2
f = d + e....... 3
Substitute 2 into 1
4c -(c-e) = f
4c -c + e =f
3c + e = f ......4
Substitute equation 3 into 4:
3c+e = d+e
subtract e from both sides
3c+e-e = d+e-e
3c = c (Proved)

3x -10+ 4x= -2 (x-4) +9
Answer:
x = 3
Step-by-step explanation:
Step 1: Write equation
3x - 10 + 4x = -2(x - 4) + 9
Step 2: Solve for x
Distribute -2: 3x - 10 + 4x = -2x + 8 + 9Combine like terms: 7x - 10 = -2x + 17Add 2x to both sides: 9x - 10 = 17Add 10 to both sides: 9x = 27Divide both sides by 9: x = 3Step 3: Check
Plug in x to verify it's a solution.
3(3) - 10 + 4(3) = -2(3 - 4) + 9
9 - 10 + 12 = -2(-1) + 9
-1 + 12 = 2 + 9
11 = 11
Suppose that 50% of the subscribers of a cable television company watch the shopping channel at least once a week. The cable company is trying to decide whether to replace this channel with a new local station. A survey of 100 subscribers will be undertaken. The cable company has decided to keep the shopping channel if the sample proportion is greater than 0.585. What is the approximate probability that the cable company will keep the shopping channel, even though the true proportion who watch it is only .50? (Round the answer to four decimal places.)
Answer:
The probability is [tex]P( p > 0.585) = 0.044565 [/tex]
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.50
The sample size is n = 100
Gnerally the mean of the sampling distribution is
[tex]\mu_x = 0.50[/tex]
Generally the standard deviation of the sampling distribution is
[tex]\sigma = \sqrt{\frac{p(1- p)}{n} }[/tex]
=> [tex]\sigma = \sqrt{\frac{0.5 (1- 0.5)}{100} }[/tex]
=> [tex]\sigma =0.05[/tex]
Generally the approximate probability that the cable company will keep the shopping channel
[tex]P( p > 0.585) = P(\frac{p- \mu_{x}}{\sigma } > \frac{0.585 - 0.50}{0.05} )[/tex]
Generally [tex]\frac{p- \mu_{x}}{\sigma } = Z (The \ standardized \ value \ of p )[/tex]
=> [tex]P( p > 0.585) = P(Z > 1.7 )[/tex]
From the z-table the probability of (Z > 1.7 ) is
[tex]P(Z > 1.7 ) = 0.044565[/tex]
So [tex]P( p > 0.585) = 0.044565 [/tex]
What is the domain of the function y=tan(x/8)?
Using it's concept, it is found that the domain of the function y = tan(x/8) is given by:
All real numbers except [tex]x \neq 4\pi + 8n\pi[/tex], where n is any integer.
What is the domain of a function?It is the set that contains all possible input values for the function.
Tangent of an angle is sine of the angle divided by the cosine of the angle, and the cosine is 0 at:
[tex]\frac{\pi}{2} + n\pi[/tex]
Hence, supposing a composite tangent function [tex]\tan{[f(x)]}[/tex], the domain is given by:
[tex]f(x) \neq \frac{\pi}{2} + n\pi[/tex]
In this problem, we have that [tex]f(x) = \frac{x}{8}[/tex], hence the domain is:
[tex]\frac{x}{8} \neq \frac{\pi}{2} + n\pi[/tex]
[tex]x \neq 4\pi + 8n\pi[/tex]
All real numbers except [tex]x \neq 4\pi + 8n\pi[/tex], where n is any integer.

Answer:
It's B
Step-by-step explanation:
You have $70 in your bank account. Each week you plan to deposit $7 from your allowance and $10 from your paycheck. The equation b = 70 + (10 + 7)w gives the amount b in your account after w weeks. How many weeks from now will you have $185 in your bank account?
Answer:
After 7 weeks from now you will have $185 in your bank account.
Step-by-step explanation:
We are given that you have $70 in your bank account. Each week you plan to deposit $7 from your allowance and $10 from your paycheck. The equation b = 70 + (10 + 7)w gives the amount b in your account after w weeks.
The equation is given by;
b = 70 + (10 + 7)w
Now, in the question, it is given that you have $185 in your bank account, that means;
$185 = $70 + $17w
Finding the value of w(weeks);
$17w = $185 - $70
$17w = $115
w = [tex]\frac{\$115}{\$17}[/tex]
w = 6.76 weeks or 7 weeks (approx).
Hence, after 7 weeks from now you will have $185 in your bank account.
