The practical meaning of the slope and y - intercept of the linear equation, C = 48x + 18 is that 48x is the variable cost depending on the number of hours and 18 is the fixed cost or the overhead change. Hence, the answer to the question above is letter A.
Counterclockwise is a rotation towards the left, as in the triangle will move to the position before it.
The correct answer is the fourth option, triangle DEF.
Hope this helps! :)
Area is multiplying the width and the length so
area= 3.2 × 1.5 = 4.8
and perimeter is adding all sides together so
perimeter= 3.2 + 3.2 + 1.5 + 1.5 = 9.4
Answer:there are 14 5point problems and 15 2point problems on the test.
Step-by-step explanation:
x represents number of 5 point questions and y represents questions worth 2 points.
The total number of questions in the test is 29. It means that
x + y = 29
x = 29 - y
Mr. Martin’s math test is worth 100 points. It means that
5x + 2y = 100 - - - - - - - - -1
Substituting x = 29 - y into equation 1, it becomes
5(29 - y) + 2y = 100
145 - 5y + 2y = 100
- 5y + 2y = 100 - 145
- 3y = - 45
y = - 45/-3
y = 15
x = 29 - y = 29 - 15
x = 14
