Y= 0.5x + 2 showing on the graph
1 answer:
Answer:
Y is output, x is input
Step-by-step explanation:
I. Given x is -1, 0, 1
II. Perform x in linear equation
If x is -1
y = 0.5(-1) + 2
y = 1.5
=> (-1, 1.5) -1 is x, 1.5 is y
If x is 0
y = 0.5(0) + 2
y = 2
=> (0, 2) 0 is x, 2 is y
If x is 1
y = 0.5(1) + 2
y = 2.5
=> (1, 2.5) 1 is x, 2.5 is y
III. Perform (x, y) in graph, there will be something like this

Answer:
The answer is x = 5.
Step-by-step explanation:
Given:
Δ ABC is an Isosceles triangle with AB = CA
m∠ ABC = ( 6x + 4 )°
m∠ BAC = 73°
m∠ BCA = ( 8y - 7 )°
To Find:
x = ?
Solution:
Properties of an Isosceles Triangle.
- Base angles or two angles are equal.
- Any two sides are equal.
Here , Δ ABC is an Isosceles triangle with AB = CA
∴ m∠ BAC = m∠ BCA
∴ m∠ BCA = ( 8y - 7 )°
= 8 × 10 - 7
m∠ BCA = 73 Which is same as ∠ CAB
Property of a Triangle is Sum of the measures of the angle of a triangle is 180°.
Substituting the values we get,
The answer is x = 5.
