Answer:
Step-by-step explanation:
<u>Slope- intercept form:</u>
<u>Given</u>
- m = -38 and point (0, 10)
As per given point, y-intercept is b = 10
<u>So the equation is:</u>
Let the number be x.
40% of the number is =
20% of 40% of the number is =
=
Given 20% of 40% of the number x is 10 greater than half the number x.
Half the number x =
So we can write the equation as ,
Now to find x, we will have to move (0.5x) to the left side by subtracting it from both sides. We will get,
Now to find x we will move (-0.42) to the right side by dividing it to both sides.
We will have to simplify 1000 and 42 by dividing the numerator and denominator by a common factor of it. 2 is a common factor of 1000 and 42.
So by dividing 1000 and 42 by 2 we will get,
We have got the required answer here. Option A is the correct option here.
Answer:
This equation demonstrates direct proportionality, as we have the form y=kx where k is the constant of proportionality. Looking at the equation, k=23 is our constant of proportionality because 23 is the constant number we multiply x by.
Answer:
?=78
Step-by-step explanation:
You plug in -3 for x. -3^2 is 9. Multiply 2*9 and subtract 5 from that. Get 13. Multiply 6 and 13 to get 78
