Answer:
slope = 5/3
Step-by-step explanation:
The line rises 5 units for each 3 units it goes to the right. (The y- and x-intercepts are clues.) The slope is the ratio of rise to run: 5/3.
Answer:
(x−3)(x−5)
Step-by-step explanation:
Let's factor x2−8x+15
x2−8x+15
The middle number is -8 and the last number is 15.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -8
Multiply together to get 15
Can you think of the two numbers?
Try -3 and -5:
-3+-5 = -8
-3*-5 = 15
Fill in the blanks in
(x+_)(x+_)
with -3 and -5 to get...
(x-3)(x-5)
Answer:
9z
Step-by-step explanation:
4th root of z = z^1/4
=> 3 * z^1/4
=> 3z^1/4
3z^1/4 * 3z^3/4
=> 3 x 3 x z^1/4 + 3/4
=> 9z^4/4
=> 9z^1
=> 9z
Answer:
359
Step-by-step explanation:
6x3+18
18 to the second power is 324
10x3=30
30+5=35
324+35=359
Plug in x.
3+y=8
Subtract 3 on both sides. (do the inverse of addition; which is subtraction)
y=5
Check your answer.
3+5=8
8=8
That checks out! y is definitely 5.
I hope this helps!
