Step-by-step explanation:
8 and 47
Final answer:
The question involves finding unknowns from a system of linear equations. By assigning 'x' as the smaller number and 'y' as the larger number, we establish two equations based on the provided information. Solving these equations, we find the smaller number to be 8 and the larger number to be 47.
Explanation:
This question involves the system of linear equations in Mathematics. To find the two numbers, establish two equations based on the information given. Let's denote the smaller number as 'x' and the larger one as 'y'.
1. The larger of two numbers is 7 more than 5 times the other, which translates into the equation:
2. Their sum is 55, which gives us the second equation: x + y = 55.
Substitute the first equation into the second, we get: Simplifying it gives us
, further simplifying leads to 6x = 48, thus x = 8. Substituting x = 8 into
we get y = 47. So, the smaller number is 8 and the larger number is 47.

Answer:
-1/2,3
Step-by-step explanation:
(2x+1)(x−3)<0
For the product to be negative, 2x+1 and x−3 have to be of the opposite signs. Consider the case when 2x+1 is positive and x−3 is negative.
2x+1>0
x−3<0
The solution satisfying both inequalities is x∈-1/2,3
Consider the case when x−3 is positive and 2x+1 is negative.
x−3>0
2x+1<0
This is false for any x.
x∈∅
The final solution is the union of the obtained solutions.

Robert paints 1/6 of a room in an hour.
Julio paints 1/8 of a room in an hour.
Working together, they can paint (1/6 + 1/8) room/hour =
(4/24 + 3/24) room/hour =
7/24 of a room per hour.
7/24 of a room per hour means
24 hours / 7 rooms =
(24 / 7) (hour/room) = (3 and 3/7) hour per room.
1/6*(6*8*x)+1/8(6*8*x)=1/x(6*8*x)
8x+6x=48
14x=48
divide each by 14
x=48/14

Answer:
y-9=-1(x+3)
Step-by-step explanation:
The formula for point slope is y2-y1=m(x2-x1). So, we can use the values of the given points to solve the equation for m, or, the slope. We get an equation with the result of 2-9=m(4+3), which gives us the slope as -1. Now, substitute your xy values back in, to get the equation
