Suppose that :
A = ( 0 , - 15 )
&
B = ( 11 , - 4 )
Slope = m = [ y(A) - y(B) ] ÷ [ x(A) - x(B) ]
Now let's juts put the coordinates in the formula to find the slope :
Slope = m = [ - 15 - ( - 4 ) ] ÷ [ 0 - 11 ]
Slope = m = [ - 15 + 4 ] ÷ [ - 11 ]
Slope = m = - 11 ÷ ( - 11 )
Slope = m = 1
Answer:
Step-by-step explanation:
You got 91% of the questions right out of 175. In math words, this is saying that:


So, you got 175 - 159 = 15.75 questions wrong. The decimal could be from getting only part of a question wrong. So you got partial credit for one question
Answer:
2/5
Step-by-step explanation:
Let k and d be the Kevin's age and the Daniel's age;
We have the equation:
k = 3 + d;
k - 2 = 4( d - 2 );
We have 3 + d - 2 = 4d - 8;
Then, d + 1 = 4d - 8;
9 = 3d;
d = 3.
Finally, k = 6 years.
