PLS HELP! ALSO INCLUDE AN EXPLAINATION LIKE I HAVE THE ANSWER I JUST DON'T KNOW HOW TO SOLVE IT.
-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.

Find the circumference and the area of a circle with radius 3 m
Use the value 3.14 for π, and do not round your answers. Be sure to include the correct units in your answers.

Answers

Answer:

The area: 28.26m^2, the circumference: 18.85m

Step-by-step explanation:

The area of a circle is 3.14(3)^2, which is 28.26, the circumference is 2(3.14)(3)=18.85m.

Answer:

Area of a circle= π[tex]r^{2}[/tex]

3.14 x [tex]3^{2}[/tex] = 18.84

The area of the circle is 18.84 [tex]m^{2}[/tex]

Circumference of a circle = 2πr

2 x 3.14 x 3 = 18.84

The circumference of the circle is 18.84 m

They are both the same number but the area is squared.

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:

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.)

B. 4m + 15 > 35

C. 4m + 15 ≥ 35

D. 4m + 15 ≤ 35

Answers

Answer:

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

X = 11. You get the answer from knowing that the inside of the triangle adds up to 180, therefore u know the bottom left is 33 since it is “opposite” of the other 33, the bottom right is 2x, and the top is 180 - 5x.
33+180-5x+2x = 180
Solve and you will get x = 11

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
