Answer:
B
Step-by-step explanation:
To find the constant of proportionality between y and x, divide
for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.
Using the method above, you should get:
Chart A = 2/5
Chart B = 1/5 (Correct Answer!)
Chart C = N/A
Hope this helps!
Answer:
$5.71
Step-by-step explanation:
20-5.88=14.12
14.12-8.41=5.71
Ok, first you need to change the 2,000 cm into meters and then you just multiply all the sides.
Given:
In triangle KLM, KL = 123 cm and measure of angle K is 35 degrees.
To find:
The length of the side KM to the nearest tenth of a centimeter.
Solution:
In a right angle triangle,

In the given right triangle KLM,



Multiply both sides by 123.



The measure of side KM is 100.8 cm.
Therefore, the correct option is (2).
Answer:
x=3 and x=-1.25
Step-by-step explanation:
4x^2-7x=15
subtract 15 from each side:
4x^2-7x-15=0
factor (trying different numbers that the sum is 7 and the quotient is 15)
(2x-6 )(2x+2.5 )=0
2x-6=0 add 6 to each side
2x=6
x=3
2x+2.5=0 subtract 2.5 from each side
2x=-2.5
x=-1.25
