If the circumference of a circle is changed from 9 cm to 3 cm, then the diameter decreases by a factor of 3.
Answer:
y = 3x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x - 7 ← is in slope- intercept form
with slope m = 3
Parallel lines have equal slopes, thus
y = 3x + c ← is the partial equation
To find c substitute (1, 4) into the partial equation
4 = 3 + c ⇒ c = 4 - 3 = 1
y = 3x + 1 ← equation of parallel line
First picture
ABC is a triangle so
m<A +m<B+m<C = 180
6x - 1 + 20 + x + 14 = 180
7x + 33 = 180
7x = 180 - 33
7x = 147
x = 147/7
x = 21
m<A = 6x - 1 = 6(21) - 1 = 125
m<C = x + 14 = 21 + 14 = 35
answer:
m<A = 125
m<C = 35
-----------------------------------------
second picture
ABC is a triangle so
m<A +m<B+m<C = 180
48 + 6x - 28 + 2x = 180
8x + 20 = 180
8x = 180 -20
8x = 160
x = 160/8
x = 20
m<B = 6x - 28 = 6(20) - 28 = 120 - 28 = 92
m<C = 2x = 2(20) = 40
answer:
x = 20
m<B = 92
m<C = 40
Answer:
Step-by-step explanation:
A(5/100)=135
A=100(135)/5
A=$2700
