Answer:
y = (4/9)x - 4
Step-by-step explanation:
4x - 9y = 36
4x - 9y - 4x = 36 - 4x
- 9y = -4x + 36
- 9y/(-9) = (-4x + 36)/(- 9)
y = (4/9)x - 4
Answer:
x = 5 and z = 108
Step-by-step explanation:
We have two intersection lines and since z and 108 lie opposite each other, they are called vertical angles. By definition, vertical angles are congruent to each other, so that means z = 108.
Now, notice that z and 6x + 42 lie on the same line. A line has a measure of 180 degrees, which means that these two will add up to 180 (they are supplementary angles). Then we can write:
z + (6x + 42) = 180
We already know that z = 108, so plug that in and solve for x:
108 + (6x + 42) = 180
6x + 150 = 180
6x = 30
x = 5
Thus, x = 5 and z = 108.
Julio began at a 4 mile elevation. Kathy began at 0 elevation. Kathy made it to 8 miles first. Kathy experienced a greater elevation change. Hope that helps :)
Answer:
After 10 weeks: 40 inches
Step-by-step explanation:
Equation
15 + 2.5w = h
15 = beginning height
2.5 = rate per week
w = weeks passed
h = total height
