Answer:
x ≤ - 2
Step-by-step explanation:
Given the inequality :
3x+5≤−1
Subtract 5 from both sides
3x + 5 - 5 ≤ - 1 - 5
3x ≤ - 6
Divide both sides by 3
3x/3 ≤ - 6/3
x ≤ - 2
Mr.Choe's error was that he changed the inequality sign. The inequality sign in this case does not need to be changed.

Answer:
x = − 5 + 1/2 √ 21 or x = − 5 + − 1/2 √ 21
Step-by-step explanation:
Let's solve your equation step-by-step.
4(x+5)^2=21
Step 1: Simplify both sides of the equation.
4x^2+40x+100=21
Step 2: Subtract 21 from both sides.
4x^2+40x+100−21 =21−21 4x^2+40x+79=0
For this equation: a=4, b=40, c=79
4x^2+40x+79=0
Step 3: Use quadratic formula with a=4, b=40, c=79.
x= −b±√ b^2−4ac/2ax
= −(40)+√ (40)^2−4(4)(79)/2(4)
x = 40^2±√ 336/8
x= −5+1/2 √ 21 or x = −5+ − 1/2√ 21
Answer: x = − 5 + 1/2 √ 21 or x = − 5 + − 1/2 √ 21

A food distribution company has employees that order food supplies for local restaurants by predicting sales. It is important that the employees order the correct amount of food. If they order too much, the food will spoil. If they don’t order enough, the restaurant will not get the food they need. The company pulls an SRS of 500 orders and finds that 408 of the orders were correct. Calculate and interpret a 95% confidence interval for the proportion of all orders that were correct.(4-step process)

A can of soup is 12 cm tall and has a radius of 4 cm.
What is the volume of soup that the can will hold?
48π cm³
80π cm³
144π cm³
192π cm³
Answer:
192π cm³
Step-by-step explanation:
First, do π(4^2). Then, multiply that times the height. So, 50.24 x 12 = 602.88. But, the question is asking your answer in terms of π. So, do 4^2 x 12. So, 4^2 x 12, gives you the answer: 192. Now change that to make it in terms of π. So, your answer will be: 192π cm³

A rectangular sheet of paper is 25/2cm long and 32/3 cm wide. Find its perimeter. *
Answer:
46.3cm
Step-by-step explanation:
perimeter is length around shape25/2 multiply by 2 becoz it's got two equal sides32/3 multiply by two for the other equal sidesadd answers together to give you46.3cmAnswer:
[tex]\frac{214}{6}[/tex]cm
Step-by-step explanation:
To find the perimeter of a rectangle, add all its sides.
Length + Length + Width + Width
[tex]\frac{25}{2} + \frac{25}{2} + \frac{32}{3} + \frac{32}{3}[/tex]
= [tex]\frac{50}{2} + \frac{64}{3}[/tex]
Find the LCM. It will be 6. Multiply the denominators with 2 and 3, respectively to get similar denominators, and that you can add.
= [tex]\frac{50}{2}\frac{X 3}{X 3}[/tex] + [tex]\frac{32}{3} \frac{X2}{X2}[/tex] (the X is the multiplication sign..)
= [tex]\frac{150}{6}[/tex] + [tex]\frac{64}{6}[/tex]
Now that the denominators are both the same, you can add the fractions.
= [tex]\frac{214}{6}[/tex]cm ( or also 35.7cm (to 3 significant figures) or [tex]35\frac{4}{6}[/tex])

Which table and graph represent the equation y = 4x?
A. Table A and graph B
B. Table B and graph A
C. Table A and graph A
D. Table B and graph B
The table and graph that represents the equation y = 4x are (D) table B and graph B
From the tables, we have:
Table A: (x,y) = (4,1), (8,2) and (12,3)
Table B: (x,y) = (1,4), (2,8) and (3,12)
From the above highlights, we can see that the y values of table B is 4 times its x values.
So, the equation of table B is:
y = 4x
The above illustration is applicable to graph B
Hence, the table and graph that represents the equation y = 4x are (D) table B and graph B

Which line is a graph of the equation: 2x + 5y = -10?
A line a
B line b
C line c
D line d
Answer: D. line d
Step-by-step explanation:
Answer: D. line d
A function is general describe as y = mx + b, so we need to set this function in y form.
2x + 5y = -10
5y = - 2x - 10 (Subtract 2x from both side, to make sure there are only y value in the left side)
y = - 2/5x -10/5 (Divide by 5 from both side)
y = -2/5x - 2 (Simplified)
-2/5x was the m or the slope, it shows how the line was change. -2/5x is negegative, which means is decreasing, and going downward, only line b and d fits.
-2 is the y-intercept, where y is equal to 0, (-2,0)
The y-intercept for line b is (2,0), so it can't be. Thus, the y-intercept for line d is (-2,0), so it fit.
