Answer:
(2, 1 )
Step-by-step explanation:
2x + 3y = 7 → (1)
3x + 2y = 8 → (2)
multiplying (1) by 3 and (2) by - 2 and adding will eliminate x
6x + 9y = 21 → (3)
- 6x - 4y = - 16 → (4)
add (3) and (4) term by term to eliminate x
0 + 5y = 5
5y = 5 ( divide both sides by 5 )
y = 1
substitute y = 1 into either of the 2 equations and solve for x
substituting into (1)
2x + 3(1) = 7
2x + 3 = 7 ( subtract 3 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
solution is (2, 1 )
Answer:
C) The graph intersects the y-axis at y=1.
Step-by-step explanation:
C is untrue because the y-intercept is given by the term "b" in the equation:
Here, m = 5 and b is equal to 0, this the graph intersects the y-axis at 0 not 1. So, C is untrue.
Answer: The domain of the function should be whole numbers.
This functions counts the number of cars that pass through an intersection as the domain (or input). Therefore, we would start counting at 0 and go up for each car.
The set of numbers {0, 1, 2, 3, 4, 5, 6, 7 ....} are called the whole numbers.
The expression is

Its distributive property which states that
Option A
Answer:
13.6 inches
Step-by-step explanation:
We can use Pythagorean theorem: 
Let c be the diagonal length, a for length, and b for width.
Substitute the values.
c=13.6 inches
