What transformation was not done to the linear parent function, f(x) = x, to get the function g(x) = - 1/2(x+5) +7
Answer:
b; vertically compressed by a factor of 2
Step-by-step explanation:
Here, we want to select from the options, the transformation that was not done on the parent function;
a) shifted up seven units
This was done
as we can see, we have + 7 from the initial 0 point
b) vertically compressed by a factor of 2
This is wrong
What we had is 1/2 multiplied by x
If there is any compressor done, it is to a factor of 1/2 and not 2
This, is thus our answer
Is y = 9x + 1/2 proportional?
Answer:
Yes it is
Step-by-step explanation:
The equation is proportional since as the value of x is increasing, y is also increasing
Equations can either be direct, inverse, or even joint. For instance, if y is directly proportional to x, this is expressed as:
y = kx
k is the variation constant
For a proportional equation, there an increase in a variable will lead to a decrease or increase in other variables
Given the expression y = 9x + 1/2,
when x = 1
y = 9(1) + 1/2
y = 9.5
when x = 2
y = 9(2) + 1/2
y = 18.5
We can see that the equation is proportional since as the value of x is increasing, y is also increasing

You work for 4 hours on Saturday and 8 hours on Sunday. You also receive a $50 bonus. You earn $164. How much did you earn per hour?
Answer:
Step-by-step explanation:
To find the hourly rate, we would first need to take the total earnings and subtract the bonus.
$164 - $50 = 114
This gives us the total money earned for hourly work.
Then we need to add the total hours worked: 4 + 8 = 12.
Lastly, we need to take the total money earned and divide it by the total hours worked: 114 / 12 = 9.50 or $9.50 per hour.
The equation could look like:
4h + 8h + $50 = $165
find the equation for the line
Answer:
y = 1/2x + 1.5
Step-by-step explanation:
first find the slope and then put it in y= x+b

4/3 divided by 2/5...............
Answer:
[tex]3 \frac{1}{3}[/tex], or 10/3
Step-by-step explanation:
4/3 ÷ 2/5 = 4/3 × 5/2 = 20/6 = [tex]3 \frac{2}{6} = 3\frac{1}{3}[/tex]
Answer:
3 1/3
Step-by-step explanation:
When we divide two fractions, such as 4/3 ÷ 2/5, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.
We also simplify the answers to fraction problems whenever possible.
So first we will change 2/5 into its reciprocal, in simple words what fraction is it when its flipped over, 5/2 right? So now we change the division into multiplication, you may or may not have heard this phrase:
Keep, Change, Flip
so now our equation looks like this:
4/3 (5/2)
In a multiplication problem it dosent matter if the denominators are the same so we just straight up multiply, which gives us 20/6. We can still simplify this by 2, so 20 divided by 2 is 10, and 6 divided by 2 is 3, so our new fraction is 10/3, now we can simplify it again to make it proper, so its 10 divided by 3, the numerator goes inside and the denominator goes outside, this gives us 3r1, the denominator (the outside number) will becomes the mixed number, the remainder will become the numerator, and the answer will become the denominator, which gives us our final answer of:
3 1/3
