Answer:
the mistake is that to "remove" the 1/2 on the left you would have to multiply by 2 (or divide by 1/2 but no one does that)
the result would be that 2h-4 = 10 should actually be 2h-4 = 20

Given h(x) = –2x – 4, solve for x when h(x)
6.
Answers
Answer:
x = -16
Step-by-step explanation:
given:
[tex]h(x) = -2x - 4[/tex]
solve for x, when:
[tex]h(x) = 6[/tex]
~~~~~~~~~~~~
➡️ [tex] x = -2(6) - 4 [/tex]
➡️ [tex] x = -12 - 4[/tex]
➡️ [tex] x = -16 [/tex]
The solution of x when the function h ( x ) = 6 is x = -5
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as h ( x )
Now , the value of h ( x ) is given by
h ( x ) = -2x - 4 be equation (1)
On simplifying the function rule , we get
when h ( x ) = 6
Substitute the value of h ( x ) = 6 , we get
6 = -2x - 4
Adding 4 on both sides , we get
-2x = 10
Divide by -2 on both sides , we get
x = 10 / -2
x = -5
Therefore , the value of x is -5
Hence , the equation is x = -5

maria worked 47 hours last week. she is paid time and a half for overtime. her gross pay last week was $757.50. what was her hourly rate?
Answers
The hourly rate is $16.11.
The following information is mentioned in the question:
Maria worked 47 hours in the last week.She paid for the overtime.The gross pay in the last week was $757.50.So, her hourly rate is
[tex]= \frac{Gross\ pay}{Number\ of\ hours} \\\\= \frac{\$757.50}{47\ hours}[/tex]
= $16.11
Here hourly rate should be measured by dividing the gross pay by the number of hours.
Therefore we can conclude that her hourly rate is $16.11
Learn more about the hourly rate here: brainly.com/question/14503751

Find the distance between the two points rounding to the nearest tenth (if necessary).
(0,-6) and (9,-1)
Answers
Hey there! I'm happy to help!
Imagine the line that is created when you connect the two points (the distance between the two points).
You can create a right triangle where this distance is the hypotenuse where the two legs are the change in x and y. So, if you take those changes in x and y, you can use the Pythagorean Theorem (a²+b²=c²) to find the distance between the two points, which is the hypotenuse.
Our change in x is 9 because 9-0 is 9.
We square it
9²=81
Our change in y is 5 as -1-(-6) or -1+6 is 5.
5²=25
We add these.
81+25=106
We square root and round to the nearest tenth.
√106≈10.3
So, our distance is 10.3.
This Pythagorean Theorem method actually gives us a formula called the distance formula that you can use to find the distance between points.

Please help me solve this question.
Answers
Answer:
C
Step-by-step explanation:
the typical form of line equation is
y = ax + b
a = the slope of the line (expressed as y/x ratio telling us how many units y changes when x changes a certain number of units).
b = the intercept on the y-axis (when x = 0).
we know, a = -4
and we use the point (x = -2, y = 1) to get b
y = -4x + b
1 = -4×-2 + b = 8 + b
b = -7
=>
y = -4x - 7
only the points of option C are all fulfilling this equation.
e.g. x = 0, y = -7
-7 = -4×0 - 7 = -7, true, -7 = -7

Answer:
Equation is 4y = -3x + 12
Step-by-step explanation:
General equation of a line:
[tex]y = mx + c[/tex]
for the slope:
[tex]slope = \frac{y_{2} - y_{1} }{x _{2} - x_{1} } [/tex]
consider points: (4, 0) and (0, 3)
[tex]slope = \frac{3 - 0}{0 - 4} \\ \\ slope = - \frac{3}{4} [/tex]
for y-intercept, c :
[tex]y = mx + c[/tex]
consider point (0, 3):
[tex]3 = ( - \frac{3}{4} \times 0) + c \\ \\ c = 3 \\ c = 3[/tex]
Equation is:

Hakim and Aziz had some savings in the ratio 3 : 5. Hakim saved another $82 and Aziz spent $110. Both have the same amount of money now. How much do each of them have now?
Answers
===========================================================
Explanation:
Hakim and Aziz have savings in the ratio 3:5. This means that Hakim has 3x dollars while Aziz has 5x dollars. The x is some positive real number.
We're then told that Hakim saved another $82, which means it goes from 3x to 3x+82
At the same time, Aziz spent $110 which means the 5x decreases to 5x-110
At this point, the two people have the same amount of money. Set the expressions we found equal to one another and solve for x.
3x+82 = 5x-110
3x-5x = -110-82
-2x = -192
x = -192/(-2)
x = 96
Then use this x value to compute each expression like so
3x+82 = 3*96+82 = 3705x-110 = 5*96-110 = 370Both have $370 after Hakim saved that additional $82 and after Aziz spent that $110.
------------------
Extra info:
If we rewind things a bit, Hakim would have 3*x = 3*96 = 288 dollars while Aziz would have 5x = 5*96 = 480 dollars. This is before any additional saving or spending.
Then note how the ratio 288:480 fully reduces to 3:5 after dividing both parts by the GCF 96.

What is the answer to 5(n-7)=2(n+14) work
Answers
Answer:
n = 21
Step-by-step explanation:
5(n-7)=2(n+14)
Distribute
5n -35 = 2n+28
Subtract 2n from each side
5n-2n -35 = 2n-2n +28
3n-35 =28
Add 35 to each side
3n-35+35 = 28+35
3n = 63
Divide by 3
3n/3 = 63/3
n =21
Answer:
The answer is n=21.
Step-by-step explanation:
To solve the equation for (n), start by using the distributive property on both sides of the equation. The distributive property is multiplying the sum of two or more addends by a number which will give the same result as multiplying each addend individually by the number and then adding the products together.
The equation will look like [tex]5n-35=2n+28[/tex] after using the distributive property. Next, add 35 to both sides of the equation, which will look like [tex]5n=2n+63[/tex], and then subtract (2n) from both sides of the equation, which will look like [tex]3n=63[/tex]. The next step is to simplify the equation, which will look like [tex]n=21[/tex], and the final answer to the equation will be [tex]n=21[/tex].
