Answer:

-1

Step-by-step explanation:

Use the rule y2-y1 / x2-x1

y1 = h

y2 = 9

x1 = -9

x2 = -8

so you get

9-h / (-8) - (-9) = 10

cross multiply to get

9-h = 10

so -h = 10-9

so h = -1

Derek was 4 years 2 months old when he joined school. Today he is 11 years 1 month old. For how long has he been in school?
lora16 [44]

Answer:

hi

Step-by-step explanation:

first of all,we should do this:

1 year is 12 month

amd 4 year is 48 month(12×4)

then we must add 2 months (wich is given) to 48

He was 50 months old when he started school

and we should find how old is he now

11 ×12=132months

132+1=133months

133-50=83 ( he has been 83 months in school)

let's turn it to years 6 years 11 months

( for finding years you should divide 83 to 12)

hope it helps

(-10) - |(-20) – (+30) |
myrzilka [38]

ANSWER: -60

EXPLANATION: To solve for (-10) - |(-20) – (+30) |, we need to do:

−10−| −20 − 30|, which equals −10−|−50|. Next, we do −10−50, which is -60.

−10−|−20−30|

= −10−|−50|

= −10−50

= −60
