Y=mx+b
b is the y intercept, and the y intercept is 1.5, (I graphed it), and the slope of the line is (-6/-7), and since they are both negative, 6/7.
so: y=6/7x+1.5
Answer:
YZ = 30 and BC = 6
Step-by-step explanation:
Since ABCDE and YXWVZ are similar figures then the ratios of corresponding sides are equal, that is
= ← 2 pairs of corresponding sides
that is
= ( cross- multiply )
3YZ = 90 ( divide both sides by 3 )
YZ = 30
Similarly
= , that is
= ( cross- multiply )
15BC = 90 ( divide both sides by 15 )
BC = 6
Each ticket is 6.5 (divide 97.5 by 15), since we know this we can think of a number close to 13, such as 11, which gives you exactly 71.50
Answer:
Part a)
Part b)
Step-by-step explanation:
Part a) we know that
-----> by supplementary angles
solve for m
Part b) we know that
The sum of the internal angles of a triangle must be equal to 180 degrees
so
in this problem
we have
substitute and solve for m
therefore
The triangle of the figure is an equilateral triangle ( has three equal angles and three equal sides)
Answer:
3 inches
Step-by-step explanation:
⇒r3=36π×3/4π
or r3=27
Taking cube root of both sides
r=3 inch
