Answer:
slope: -3/4 y-intercept: 3 equation: y=(-3/4)x+3
Find delta y/delta x
(10-7)/(15-12)=3/3=1, (15-10)/(20-15)=5/5=1
y=x+b, using any point, I'll use (20,15) we can solve for b...
15=20+b
b=-5 so our line is:
y=x-5, and we want to know when y=17
17=x-5
x=22
so n=22
It's has line of symmetry only
Answer:
C =28.26m
Step-by-step explanation:
We are walking around a circle, which means we are finding the perimeter. The perimeter of a circle is called the circumference.
We find the circumference by
C = pi *d where d is the diameter
C = 3.14 * 9
C =28.26m
Answer:
Break-even point in units= 40
Step-by-step explanation:
Giving the following information:
Unitary variable cost= $20
Selling price per unit= $30
Fxed costs= $400
<u>To calculate the break-even point in units, we need to use the following formula:</u>
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 400 / (30 - 20)
Break-even point in units= 40
