Answer:
John reads an equal number of pages of a book every week. The graph below shows the number of pages of the book left to read, y, after x weeks. The equation best models the relationship between x and y is y = −25x + 175
Step-by-step explanation:
Answer:
The expression is 
Step-by-step explanation:
<u><em> Step(i):-</em></u>
Given variable start with 'x'
The variable 'x' is divided by '3' so 
<u><em>Step(ii):</em></u>-
The variable 'x' is divided by '3' so and after that subtract '6'
Then the expression
Let the number of baskets be x
Let the number of points be y
32 +3x = y
19 + 4x = y
Rearrange both equations then solve them as simultaneous equations
32 = y - 3x
19 = y - 4x
y - 3x = 32
- y - 4x = 19
x = 13
Substitute x into one of the equations
y - 3x = 32
y - (3 x 13) = 32
y - 39 = 32
y = 32 + 39
y = 71
Number of baskets (x) = 13
Number of points (y) = 71
Answer:
j = -99
Step-by-step explanation:
-3(j+82)=51
Divide by -3
-3/-3(j+82)=51/-3
j+82 = -17
Subtract 82 from each side
j+82-82 = -17-82
j = -99
