4x+3y=7
3x-2y=9
12x+9y=21
12x-8y=36
^^Multiply top equation by 3 and multiply bottom equation by 4
12x+9y=36
- 12x-8y=36
17y=-15
^^Then subtract those two new equations
17y/17= -15/17
Y= -0.88
^^Next divide both sides by 17
4x+3* -0.88=7
4x + (-2.64) =7
-(-2.64) -(-2.64)
4x = 9.64
4x/4=9.64/4
X=2.41
^^then choose on equation and put your new y in the y spot and solve.
X=2.41
Y=-0.88
Your point/coordinate is (2.41,-.88)
Answer:
Value of middle 7 = (value of 7 to the left of the middle 7)
Value of middle 7 = (value of 7 to the right of the middle 7)
Step-by-step explanation:
7 in the middle of number is equal to
7 to the left of the middle 7 is equal to
So,
That is value of middle 7 = (value of 7 to the left of the middle 7)
Also,
7 to the right of the middle 7 is equal to
So,
That is value of middle 7 = (value of 7 to the right of the middle 7)

Step-by-step explanation:
2134/12=177.83
Answer: 13.3
Step-by-step explanation:
Since angles in a triangle add to 180 degrees, we know that in triangle UWV, . Thus, the triangles are similar by AA.
Since corresponding sides of similar triangles are proportional,
Answer: B
Step-by-step explanation:
so for the slope to be parallel, it means it's the same slope as the given equation which is -5
using point slope, we can write a new equation
y -5 = -5(x+3)
y -5 = -5x-15
y = -5x-10
