Answer:
Yes
Step-by-step explanation:
it can be written as a fraction
Y=6x-24
substitute 18 for y
18=6x-24
add 24 on both sides
42=6x
divide both sides by 6
7=x
Answer: 100° and 80°
==================================
working:
supplementary angles = angle + angle = 180°
let the larger angle be x
smaller angle = (x/2) + 30
x + ((x/2) + 30) = 180°
(2x + x + 60) / 2 = 180°
3x + 60 = 360°
3x = 300°
x = 100°
Therefore the larger angle is 100°
smaller angle
= (100° / 2) + 30°
= 80°
Therefore, the two supplementary angles are 100° and 80°
Answer:
The credit remaining on a phone card (in dollars) is a linear function of the
total calling time made with the card (in minutes), as shown in the figure below.
The remaining credit after 45 minutes of calls is $22.80 , and the remaining
credit after 64 minutes of calls is $19.76.
Step-by-step explanation:
What is the remaining credit after 73 minutes of calls?
;
Not sure what figure you are referring to, write an equation from the given values:
Assign the values as follows
x1 = 45; y1 = 22.80
x2 = 64; y2 = 19.76
:
Find the slope (m) using the formula: m = %28y2-y1%29%2F%28x2-x1%29
m = %2819.76-22.80%29%2F%2864-45%29 = %28-3.04%29%2F%2819%29
m = -.16
