Answer:
14
Step-by-step explanation:
1. Do the "Two Mark" Rule
- 7 + (+12) - 5
2. Do your addition before subtracting
- 7 + 12 = 19
3. Subtract your remaining two numbers
- 19 - 5 = 14
Answer/Step-by-step explanation:
2. Using two pairs of values, (0, 59) and (2,000, 51),

3. The y-intercept is the value of y when x = 0. Thus, x = 0, when y = 59. Therefore,
y-intercept (b) = 59
4. To write an equation in slope-intercept form, simply substitute m = -¹/250, and b = 59, in 
✅
5. Substitute x = 5,000 in
.



At an altitude of 5,000 ft, temperature would be 39°F
A. = logb (3/7)^1/2
= logb 3^1/2 - logb 7^1/2
= 1/2(logb 3 - logb 7)
b. = log 7x^3 + log y^5
= log 7 + log x^3 + log y^5
= log 7 + 3 log x + 5 log y
Answer:
x=1
Step-by-step explanation:
Subtract
18
from both sides
Simplify
3
Subtract
2x
from both sides
