<h3>Answers:</h3>
The value x is x = 15
The three sides of the triangle are
x+10 = 25
2x-5 = 25
3x-15 = 30
==================================================
Work Shown:
The curved angle markers indicate those two angles are the same measure. The sides opposite those angles are the same length. So 2x-5 and x+10 are the same value
2x-5 = x+10
2x-x = 10+5
x = 15
Once we know x, we can find the length of each side
x+10 = 15+10 = 25
2x-5 = 2*15-5 = 30-5 = 25
This also helps confirm we have the right x value (since we got the same value for each expression)
3x-15 = 3*15-15 = 45-15 = 30
This is an isosceles triangle because exactly two sides are the same length.
Answer:
x = 6
Step-by-step explanation:
Given
2x - 5 = 7 ( add 5 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Answer: B
Step-by-step explanation:
I did the quiz
400 miles -----------4 hours
X miles ------------2 hours
4x=400.2
4x=800
X=200
Or
400miles --------------- 4hours
X miles --------------- 6 hours
4x=400.6
4x=2.400
X= 600
The inequalities and the points are
- y + 2 ≤ 5x: (5, -2) and (10, 1)
- y + x > -4: (5, -2) and (10, 1)
- y ≤ 1/3x: (5, -2) and (10, 1))
<h3>How to graph the
system of inequalities?</h3>
The system of inequalities is given as:
y + 2 ≤ 5x
y + x > -4
y ≤ 1/3x
Next, we plot each inequality in the system of inequalities using a graphing calculator
See attachment for the graph of the system of inequalities y + 2 ≤ 5x, y + x > -4 and y ≤ 1/3x
From the attached graph, we have the following points:
y + 2 ≤ 5x: (5, -2) and (10, 1)
y + x > -4: (5, -2) and (10, 1)
y ≤ 1/3x: (5, -2) and (10, 1)
