Answer:
D -1
Step-by-step explanation:
3(x+1) = 2(x-1)
Use distributive property and get;
3x+3 = 2x-2
Add 2 to both sides,
3x+5 = 2x+4
Subtract 2x from both sides
1x+5 = 4
Subtract 5 from both sides
1x=-1
x = -1
A.5/11x
B.1/2x
C.x/2
D.5x/12
You must divide the numerator and denominator by the great common multiple. The greatest common multiple of 25 and 55 is 5. 25 divided by 5 equals 5 (numerator), and 55x divided by 5 is 11x (denominator). Therefore the answer is A. 5/11x
Answer: A. intersecting
Step-by-step explanation:
1. To solve this problem and classify the system of equations shown above, you can graph it has you can see in the graph attached.
2. As you can see the lines intersect each other, this means that the system of equation has one solution and the lines are intersecting.
3. Therefore, the answer is the option A: Intersecting.
Answer:
A. intersecting
Step-by-step explanation:
write the equations in the from of y = mx + c
Where m = slope
c = y-intercept.
1/3x + y + 2 = 0
1/3x + y = -2
y = -1/3x - 2
1/2x + y - 5 = 0
1/2x + y = 5
y = -1/2x + 5
The equations are not parallel
-1/3x - 2 = -1/2x + 5
1/2x - 1/3x = 5 + 2
1/6x = 7
x = 7× 6/1
= 42
y = -1/3×42 -2
= -14 - 2
= -16
The equations intersect at point (42,-16)
–28

The mathematical expression is 6y + 15 for the product of 6, and Y increased by 15.
It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The mathematical pression in word form is:
The product of 6 and Y increased by 15:
As we know, the linear expression can be defined as the relation between two variables, if we plot the graph of the linear expression we will get a straight line.
If in the linear expression, one variable is present, then the expression is known as the linear expression in one variable.
Here y is the number.
The expression is:
6y+15
Thus, the mathematical expression is 6y + 15 for the product of 6, and Y increased by 15 after using the concept of linear expression.
