Answer:
Angle 2 = 27 and Angle 1 = 135
Step-by-step explanation:
Let x = angle 2
Let 5x = angle 1
5x+x=162
6x=162
x=27
Angle 1 = 5(27)
Angle 1 = 135
The table is:
Number of washes denoted by x: 0, 8, 12
Amount left on card denoted by y: 30, 18, 12
a.
Write an equation that shows the amount of
dollars left on the card
Solution:
18 – 30 divided by 8 – 0 = -12/8
On simplest form is -3/2
The equation is y = -3/2x + 30
b.
Explain the meaning of the negative slope above.
As the number of car washes increase,
the dollars left on the card decreases.
c.
What is the maximum value of x?
0 = -3/2x + 30
2/3 x 3/2 x = 30/1 x 2/3
Cancel 2/3 x 3/2 and reduce 30 by 3 we get
10, 10 x 2
x = 20
Answer:
116 degrees
Explanation:
If we divide the triangle from the vertex of the triangle, the vertex angle of each triangle would lie on a straight line in the triangle. Angle on a straight line is 180 degrees.
If the vertex angle of one triangle is 64 degrees then the vertex angle x of the other triangle is 180 degrees - 64 degrees = 116 degrees.
Answer:
3 lines of symmetry
Step-by-step explanation:
Symmetry : Reflected images.
In the picture, there are 6 lines. We can connect 2 of the lines to make a line of symmetry. That will make 3 lines.
