(180-76) + 42 + (180-x) = 180
104 + 42 + 180 - x = 180
-x = 180 - 326
x = 146°
Answer:
The answer is b. the range of Greta's graph is y<0
Step-by-step explanation:
Answer:
y= 2x+1
Step-by-step explanation:
Points:
Form of the line:
- y=mx+b, m- the slope, b- y-intercept
Finding the slope:
- m= (y2-y1)/(x2-x1)
- m=(3-1)/(1-0)= 2/1= 2
Line is now:
Using one of the given points to find out the value of b:
So the equation for the line is:
9 + 3 - 5
9 + 3 = 12
12 - 5 = 7
We can use the formula d = rt in getting the algebraic equation for the two cars where; d = distance, r = rate, t = time.
Given:

(blue car) = 35 miles per hour

(red car) = 70 miles per hour
distance between the two towns = 140 miles

(blue car)= no. of hours the blue car travels

(red car) = no. of hours the red car travels
Linear equation for the blue car




blue car travels 4 hours from town A to town B.
Linear equation for the red car




red car travels 2 hours from town A to town B.
