Answer:
(-11) and (-4y)
Step-by-step explanation:
Whenever a question has a - sign it always has to be re-written into an addition expression. For example
-7-9
You have to change it into...
-7+(-9) because you can't solve and integer expression with a subtraction sign, it'll be wrong.
So, use the distance between two points formula:squareroot((x2-x1)^2+(y2-y1)^2)
squareroot((-7--4)^2+(8-7)^2)
squareroot((-3)^2+(1)^2)
squareroot((9+1)
squareroot(10)
squareroot 10 can be simplified to 3.2 units
The length I’m guessing is either 2 because 7 x 2 = 14 or it’s 7 because 7 + 7 = 14. But I would go with 2.
0.0175, 0.65, 0.876
The smallest among these is 0.0175
after the decimal point, we see that in 0.0175 the tenth value is 0
in 0.65 the tenth value is 6
and in 0.876 the tenth value is 8
So from smallest to biggest(if needed)
0.0175, 0.65, 0.876
Answer:
$40
Step-by-step explanation:
If you were to purchase 7 picture frames, you would replace x in the equation with 7, this is shown below.
<u>f(x)=9x-23 ---> f(x)=9(7)-23</u>
Now we can solve for f(x). First start with 9(7).
<u>f(x)=9(7)-23 ---> f(x)=63-23</u>
Now finish the last part by subtracting 23 from 63.
<u>f(x)=63-23 ---> f(x)=40</u>
This means that you would have to pay $40 dollars to purchase the 7 picture frames.
