Answer:
-4
Step-by-step explanation:
1. They are alternate exteriors meaning they are supposed to be the same so you sort the equation like 134+x=130
2. Then you pass 134 both side like ×=130
-134
3. Which will equal :-4
Answer: Option A

Step-by-step explanation:
In the graph we have a piecewise function composed of a parabola and a line.
The parabola has the vertex in the point (0, 2) and cuts the y-axis in y = 2.
The equation of this parabola is
Then we have an equation line
Note that the interval in which the parabola is defined is from -∞ to x = 1. Note that the parabola does not include the point x = 1 because it is marked with an empty circle " о ."
(this is
)
Then the equation of the line goes from x = 1 to ∞ . In this case, the line includes x = 1 because the point at the end of the line is represented by a full circle
.
(this is
)
Then the function is:

Answer:
Step-by-step explanation:
Set this up as a proportion, with inches on the top and feet on the bottom for our scale. We will find the actual length first, then we'll find the width.

Cross multiply to get that the actual length is 5(2.5) = 12.5 feet. Now for the width:

Cross multiply to get that the actual width is 5(3) = 15 feet.
If you want the area of the room, multiply the length times the width to get
A = 15(12.5)
A = 187.5 feet squared
Answer: 6
A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression.
In this case we want to find the coefficient that has x. 6 is the only coefficient in the expression 6x + 9y + 15z that has the coefficient of x.
Basically, a coefficient is simply a number that has a variable after it.
Answer:
-1/1 or -1
Step-by-step explanation:
subtract y: 3-4= -1
subtract x: 2-1=1
answer: -1/1
