Answer:
Step-by-step explanation:
we have the points
(0,-3),(2,0) and (4,3)
step 1
Find the slope
The formula to calculate the slope between two points is equal to
we take
(0,-3),(2,0)
substitute the values in the formula
step 2
Find the equation of the line in slope intercept form
we have
-----> the point (0,-3) is the y-intercept
substitute
The graph in the attached figure
Answer:
2.38 miles
Step-by-step explanation:
From Given diagram:
In ΔABC,
AC=2.5 miles
BC= 3.7 miles
∠BCA= 39.4°
Now as we have two sides and an angle, using law of cosines to find the third side:
c= √(a^2+b^2-2abcosα
AB=√(AC)^2 + (BC)^2 - 2(AC)(BC)cosα
=√(2.5)^2 + (3.7)^2 - 2(2.5)(3.7)cos(39.4°)
=√(2.5)^2 + (3.7)^2 - 2(2.5)(3.7)(0.77)
=√(5.695)
= 2.38 !
Answer:
a proportional relationship exists if the ratio of values is a constant
Step-by-step explanation:
The equation describing a proportional relationship is ...
y = kx
If you are given a table of values of x and y, they will be proportional if ...
y/x = k
for all (x, y) pairs.
The temperature rose by 47 degrees Fahrenheit, because it first went from -32 to 0, and then from 0 to 15.
