Please tell me the answer to these questions ASAP.

1. 900

2. 50 dollars

3. 6 weeks

4. 300 dollars

5. 75 dollars

1. when the number of weeks are at 0, the money she has in her account is 900. So, she has 900 dollars in her account at the beginning.

2. she starts off with 900. The next week, she has 850 in her account, then 800, and so on. therefore, she spends 50 dollars a week.

3. 1/3 times 900 is 300, so she needs to spend 300 dollars. 300/50 is 6, so it will take her 6 weeks to spend 300 dollars.

4. If she spends 50 a week over 12 weeks then multiply 50 and 12. You get 600. we know she starts with 90p, so 900-600 is 300. she spends 600 and ends up with 300 in 12 weeks.

5. we know she spends 50 a week. 50 times 1.5 is 75, so hee brother spends 75 dollars a week

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
