How would I find the range btw im only allowed a Ti-84 calculator So pls tell me how to solve this without using any stepbystep caulculators or desmos

Answers

Answer:

D

Step-by-step explanation:

u dont really need a calculator for this problem

to find the answer, you have to look at the equation.

f(x)=20x+4

the 4 is the y-intercept (0,4), which tells us that the range will start from number 4.

the 20x tells u to multiply the x by the 20

so if it was 20(1)=20, 20(2)= 40, 20(3)= 60 ....

so if you add x amount of plates to the barbell, it will be 20 times x plus 4(because 4lbs is the weight of the barbell itself)

so 0 plates is 4, 1 plate is 20(2) + 4 = 44, 20(4)+4= 84 ....

(i didnt do 20(1) or 20(3) because you need to have a even number of plates of each side of the barbell.)

pls help i will give brainliest to the correct answer!! :)

Sandra saves 10% of her salary for retirement. This year her salary was $1,000 more than in the previous
year, and she saved $4,200. What was her salary in the previous year?

Answers

Answer:

$41000

Step-by-step explanation:

If her salary was $1,000 more than the previous year and she save $4,200, $4,200 was 10% of her salary. So we should create an equation. (x being her salary from the previous year)

0.1(x+1000)=4200 (divide 4200 by .01)

x+100=42000

42000-1000= 41000

$41000 sorry if i am wrong :(

Maria is making a gelatin dessert for a party. She plans on making 12 servings for every 6 people. If each pan Maria uses to make the dessert holds 8 servings, what is the minimum number of these pans will she needs in order to serve 112 people?

Please I really need help.

Answers

Very easy!
6 people= 12 servings so 1 person= 2 servings
We have 112 people so we need 112 x 2= 224 servings
So she will make 224 servings with an 8 servings pan, 224/8= 28 pans.
The minimum number of pans she need in order to serve 112 people is 28 pans!

-10 ≤ 2(2x + 7) ≤ 10.

Answers

Answer:

Step-by-step explanation: So first I changed 2(2x + 7) with the distributive property:

4x + 14

Since the above has to be less than or equal to 10, I know that x has to be negative.

If we make x = -1, 4x + 14 simplifies to -4 + 14, which simplifies to 10.

This satisfies the inequality, since it is greater than or equal to -10, and less than or equal to -10.

Hope this explained it well!

Answer:

-6 ≤ x ≤ -1.

Step-by-step explanation:

-10 ≤ 2(2x + 7) ≤ 10

Split it up into 2 inequalities:

2(2x + 7) ≥ -10    (reading from the middle to the left)

4x + 14  ≥ -10

4x  ≥ -24

x  ≥ -6.

and:

2(2x + 7) ≤ 10

4x + 14 ≤ 10

4x ≤ -4

x ≤ -1.

Combining the 2 we have:

-6 ≤ x ≤ -1.

Jason is training to run a marathon. His goal for this week is to run a minimum of 35 miles. So far this week, he has already run 15 miles. Which inequality could be used to determine the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal?

A. 4m – 15 ≥ 35

B. 4m + 15 > 35

C. 4m + 15 ≥ 35

D. 4m + 15 ≤ 35

Answers

Answer:

C

Step-by-step explanation:

it says a minimum of 35 miles so that means it can be equal to 35 or more. He only ran 15 miles so he would have to run more. That’s why there would be a plus sign

The answer is c because he need to run in 4 more day and so 4m + 15 > would be 35 your welcome

To avold a storm, a passenger-jet pilot descended 0.44mile in 0.8 minute. What was the plane's average change of altitude per minute?

Answers

Descends 0.55 miles per minute
Answer:
in order to find the answer you have to divide 0.44 by 0.8
when you divide decimals, the number that goes outside needs to be a whole number so it has to be 8
since you moved the decimal you also have to move the decimal from the inside. If you move the decimal it is going to be 4.4
so now you divide those numbers. 4.4/8
