D. 3 If you multiply each side of △ABC (ex: 5) by 3, you get the same side on △DEF
5x3 = 15
4x3 = 12
3x3 = 9
Answer:c
Step-by-step explanation:
w - 7 > - 4 To solve the inequality, you need to get the variable (w) by itself, to do so, you add 7 on both sides of the inequality
w - 7 + 7 > -4 + 7
w > 3 [w is a number greater than 3]
(If you are using an open circle and closed circle, otherwise you can skip)
When the sign is < or >, you have an open circle "o"
When the sign is ≤ or ≥ (less/greater than or equal to), you have a closed circle
Make an open circle on the number 3, then make an arrow pointing to the right because w is greater than 3.
If you don't have to do the open/closed circle, just make a dot on the number 3 and make an arrow pointing/going to the right
Answer:
y = 2 ± 
Step-by-step explanation:
Solve using separable equations
First put x and dx on the same side and do the same for y
(y-2)dy = (x-2)dx
Now you can integrate
+ C1
Now we depending on how what ur instructor wants you may need to give exact solutions. We can do this by solving he quadratic equation for Y
Doing this you get:
y = 2 ±
<em>Note C's were simplified.</em>
Answer: After 5 minutes, the plane is at 20,000 feet. It descended a total of 10,000 feet.
Step-by-step explanation:
f = feet above ground
r = rate of descent
m = minutes
f = 30000 - r · m
f = 30000 - 20000m
After five minutes:
f = 30000 - 2000(5)
f = 30000 - 10000
f = 20000
