Answer:
1. 8x2 - 7x + 4x3 - 2-3x2 + 9x - 4 = 16+2x
Step-by-step explanation:
1. Multiply all the multiplication problems (should look like this --> 16-7x+12-2-6+9x-4)
2. Calculate the sum or difference (should end up looking like this --> 16-7x+9x) and then into this (16 +2x)
Bringing us to the answer → 16 + 2x!

The area A of the rectangle shown
is described with the inequality
60 A 140. Write and solve a
compound inequality for x.
Step-by-step explanation:
Simplifying
4x + -5 = 20x
Reorder the terms:
-5 + 4x = 20x
Solving
-5 + 4x = 20x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-20x' to each side of the equation.
-5 + 4x + -20x = 20x + -20x
Combine like terms: 4x + -20x = -16x
-5 + -16x = 20x + -20x
Combine like terms: 20x + -20x = 0
-5 + -16x = 0
Add '5' to each side of the equation.
-5 + 5 + -16x = 0 + 5
Combine like terms: -5 + 5 = 0
0 + -16x = 0 + 5
-16x = 0 + 5
Combine like terms: 0 + 5 = 5
-16x = 5
Divide each side by '-16'.
x = -0.3125
Simplifying
x = -0.3125

f(x) = |3x-2|
f(-5) = |3(-5)-2| ... replace every x with -5
f(-5) = |-15-2|
f(-5) = |-17|
f(-5) = 17

Repeat for x = 7
f(x) = |3x-2|
f(7) = |3*7-2| ... replace every x with 7

Find the slope of a line parallel and perpendicular to the line with given coordinates: (7, -2) and (1, -3).
Answer:
[tex]m=\frac{1}{6}[/tex] (Parallel)
[tex]m=-6[/tex] (Perpendicular)
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply plug in the 2 coordinates into the slope formula to find slope m:
[tex]m=\frac{-3-(-2)}{1-7}[/tex]
[tex]m=\frac{-3+2}{-6}[/tex]
[tex]m=\frac{-1}{-6}[/tex]
[tex]m=\frac{1}{6}[/tex]
A parallel line always has the same slope as the original.
[tex]m=\frac{1}{6}[/tex] (Original)
[tex]m=\frac{1}{6}[/tex] (Parallel)
A perpendicular line always has the negative reciprocal slope of the original.
[tex]m=\frac{1}{6}[/tex] (Original)
[tex]m=-6[/tex] (Perpendicular)

A test tube is cylindrical in shape with a length of 152 mm and a radius of 6.5 mm. What is the volume of the test tube? Report your answer in mm3 but do not include the unit mm3 in your answer box. Round your answer to the nearest whole number and do not include commas in your answer. The formula for volume of a cylinder is V=πr2h.
Answer:
20165
Step-by-step explanation:
Given:
Length/height (h) of cylindrical test tube = 152 mm
Radius of cylindrical test tube = 6.5 mm
Volume = [tex] \pi r^2h [/tex]
Required:
Volume of cylinder to nearest whole number
Solution:
The volume is given as [tex] V = \pi r^2h [/tex]
Take π as 3.14 and plug the values of r and h into the volume formula.
[tex] V = 3.14*6.5^2*152 [/tex]
[tex] V = 3.14*6.5*152 = 20165.08 [/tex]
Volume of the test tube = 20165 mm³ (nearest whole number)

Item 19 Question 1 A nurse is making identical first aid bags for patients using 72 antiseptic wipes, 55 adhesive bandages, and 36 packets of ointment. What is the greatest number of identical first aid bags the nurse can make with the least amount of items leftover? Describe the contents of each bag.
Answer:
36 identical bags with 2 antiseptic wipes, 1 adhesive bandage and 1 ointment in each bag.
Leftovers: 19 adhesive bandages.
Step-by-step explanation:
First of all, let us try to find out the maximum number of identical first aid bags that can be prepared from the given contents.
The maximum number of bags that can be prepared will be equal to the quantity of the content which is available in minimum amount.
And that is number of packets of ointments.
Therefore, greatest number of bags that can be prepared is 36.
Now, it can be seen that 72 antiseptic wipes are available.
72 is a multiple of 36.
Therefore, if we put 2 antiseptic wipes in each bag, no leftovers will be there for packet of ointments and antiseptic wipes.
Now, let us consider adhesive bandages.
Maximum of 1 adhesive bandages can be put in each bag because only 55 such bandages are available.
Therefore, the answer is:
36 identical bags with 2 antiseptic wipes, 1 adhesive bandage and 1 ointment in each bag.
Leftovers: 19 adhesive bandages.
