To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for and solve for y. <em>x-intercept(s): (2,0)</em> <em>y-intercept(s): (0,−10)</em>
<span>Assuming that 2 people who will repair a refrigerator equally fast will do it twice as fast when working together:
Jannete repairs 1/60 refrigerator per minute.
Lisa repairs 1/40 refrigerator per minute.
Togheter they repair 1/60+1/40= 1/60 + 1,5/60 = 2,5/60=5/120=1/24 refrigerator per minute
thus it will take them 24 minutes</span>

Answer:
b 1/4 (n-64)
Step-by-step explanation:
Multiplying the expression by 1 does not change its value:
= (1/4)(4) × (1/4n -16)
= (1/4) × (4(1/4n -16)) . . . . . associative property
= (1/4) × ((4/4)n -4·16) . . . . distributive property
= (1/4)(n -64) . . . . matches choice B
Answer: She can visit the city on 192 ways.
Step-by-step explanation: If Sally starts from city A, and after going from 4 cities she returns to home, then that can be on 4! = 24 ways.
Hi! So in this you use the Pythagorean Theorem. In triangle CBD, you would do 6^2 + 4.2 ^2 = y ^2. You take the square root of that answer to get the dumber. Then, you would have 2 sides for triangle CAD, so you could just do it again, getting the answer for X. I hope that helps. I don’t know if that is how you are learning it or not, but that is a way to solve.
