Answer is A
if x+y=5
y= -x+5
2x + (-x+5) =-2
2x -x +5 = -2
x+5 = -2
x=-7
Answer:
-5
Step-by-step explanation:
You will need to set up and solve 2 equations:
A) 3 Vans + 10 Buses = 379
B) 14Vans + 13 Buses = 624
Multiply equation A by -14
A) -42 Vans -140 Buses = -5,306 then Multiply equation B by 3
B) 42 Vans + 39 Buses = 1,872
Adding BOTH equations
-101 Buses = -3,434
Each Bus holds 34 Students
Putting this into equation A
A) 3 Vans + 10 Buses = 379
A) 3 Vans + 10 * 34 = 379
A) 3 Vans +340 = 379
A) 3 Vans = 39
Each van = 13 students
Answer:
<em>The denominator is 12</em>
Step-by-step explanation:
<u>The Number Line</u>
We can represent any real number in a properly segmented line, where the zero-mark is the separation between positive numbers to its right side and negative numbers to the left side.
We are given the number x = 2/3. Since it's positive, its location lies to the right of the zero but before the 1 as shown in the figure below.
We want to locate a second point y at the same distance from 0 as the point x, so we have two options: y is the same as x, or y is negative at the same distance from zero. We chose the last option.
Its numerator must be 8, so we need to multiply it by 4. But we cannot alter the value of x, so we must also multiply the denominator by 4, which gives us the fraction 8/12, but recall it must be negative.
The denominator is 12
The cost of the apples is a function of their weight option (A) is correct because the independent variable (x) is the weight of the apples.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
The options are:
- A. The cost of the apples is a function of their weight.
- B. The weight of the apples is a function of the number of apples.
- C. The cost of the apples is a function of the type of apples.
- D. The weight of the apples is a function of their cost.
From the graph:
The y-axis is representing the cost(c) of the apples in dollars and
The x-axis is representing the weight(w) of the apples in pounds.
c = f(w)
The independent variable (w) is the weight of the apples
The dependent variable (c) is the cost of the apples
Thus, the cost of the apples is a function of their weight option (A) is correct because the independent variable (w) is the weight of the apples.
