2=m/2−7
Simplify both sides of the equation.
2=m/2−7
2=1/2m+−7
2=1/2m−7
Flip the equation.
1/2m−7=2
Add 7 to both sides.
1/2m−7+7=2+7
1/2m=9
Multiply both sides by 2.
2*(1/2m)=(2)*(9)
m=18
Answer:
Total number of points in the test = 100
Total number of items in the test = 40
Let number of items of 2 points be x and number of items of 3 points be y.
Now, using the given information the situation can be represented by using the following equations :
⇒ x + y = 40 .........(1)
⇒ 2x + 3y = 100 .........(2)
The matrix equation is :
By solving the equation (1) and equation (2), we get :
Solution : x = 20 and y = 20
Answer:
Step-by-step explanation:
The given line has equation
The steepness is the absolute value of the slope.
The larger the absolute value of the slope, the greater the steepness.
The steepness of
is
The steepness of
is
Therefore the second line is less steep than the first line.
