Answer:
2 - 10x
Step-by-step explanation:
Given
6 - 2x - 4 (2x + 1) ← distribute parenthesis by - 4
= 6 - 2x - 8x - 4 ← collect like terms
= 2 - 10x

Answers: 49, 1, 49
Those values go in the blanks from left to right
=====================================================
Explanation:
The rule we use is x^(-k) = 1/(x^k)
That means if we're evaluating something like 7^(-1), then it's the same as 1/(7^1) = 1/7 which explains how x = -1 leads to y = 1/7.
Similarly, 7^(-2) = 1/(7^2) = 1/49 is the y value when x = -2. So you'll type 49 into the first box to fill in that missing denominator.
Raising any nonzero value to the zeroth power leads to 1. That rule is x^0 = 1 where x can be anything you want but it can't be zero. Therefore 7^0 = 1 goes in the second box.
Lastly, 7^2 = 7*7 = 49 will go in the third box.

Type the expression that results from the following series
of steps:
Start with x and multiply by itself.
Answer: x^2 (the ^ represents that the next number is an exponent)
Step-by-step explanation:
Any number squared (to the power of 2) is just itself multiplied by itself. Remember, multiplication is repeated addition and exponents are repeated multiplication.
Simplify this expression. Assume that x is nonzero.
x^−11•x^2
Answer:
x^-11•x^2
using the law of indices...
x^(-11+2)

whats the greatest 10 you can multiply by 19 to get close to, , but not over, 684?
Answer:
the desire expression is 19multiply(3 tens)=19multiply30=570
Step-by-step explanation:
19 ✖️ 1ten=19 ✖️ 10=190
19 ✖️2tens=19 ✖️ 20=380
19 ✖️ 3tens=19 ✖️ 30=570
19 ✖️ 4tens=19 ✖️ 40=760
but here 760 is over the given terms 684,but 570 is the nearest value to the value 684
so the desire expression is 19 ✖️ 3tens=19 ✖️ 30=570

Pleaseee don’t answer if you don’t know, I need this really soon.
Step-by-step explanation:
a)
[tex]\sin^{2}x + \cos^{2}x = 1[/tex]
Dividing both sides by sin^2x, we get
[tex]1 + \frac{\cos^{2}x }{ \sin^{2}x} = \frac{1}{\sin^{2}x } [/tex]
The 2nd term on the LHS is simply cot^2x and the RHS is simply csc^2x
[tex]1 + \cot^{2}x = \csc^{2}x[/tex]
b)
[tex]2 \sin x = 1[/tex]
[tex] \sin x = \frac{1}{2} [/tex]
[tex]x = \sin^{ - 1} (\frac{1}{2}) = \frac{\pi}{6} [/tex]
You can also graph it to arrive at the solution.

Step-by-step explanation:
mark brainliest if you could please! good luck!
Answer:
D. 16/24
Step-by-step explanation:
the 2 and 3 need to be multiplied by the same number for it to be equivalent.
16/2 = 8
24/3 = 8
So 16/24 is equivalent to 2/3.

Ms. Lee works at a pizzeria. She delivers an average of 3 pizza orders per hour. The pizzeria is offering a bonus to employees who complete 200 deliveries or more in a month. She has delivered 26 orders so far this month. How many more hours, x, does Ms. Lee need to work to get the bonus?
Answer:
58 hours.
Which can also be 2days 10 hours.
Step-by-step explanation:
3 pizza orders = 1hour
200 deliveries per month= bonus
26 orders so far this month.
X= 200-26= 174
174 divided by 3 = 58 hours.

A jar contains 3 blue marbles and 2 red marbles. A marble is randomly selected from the jar and replaced, and then a second marble is chosen.
What is the probability that the blue marble was chosen both times?
Answer:
3/5
Step-by-step explanation:
3+2=5. 3/5 is the blue marble. You may also say 6/10. It is likely you will pull out a blue marble.
probability that the blue marble was chosen both times 6/10.
What is probability?It is a branch of mathematics that deals with the occurrence of a random event.
Jar contains 3 blue marbles.
Jar contains 2 red marbles.
Total marbles= 5
If she replaced a marble and second time she choose a marble gets blue.
Then, probability of blue marble= 3/5.
But for both the probability for both instance will be 3/5 i.e.,
= 3/5*2/2
= 6/10
Hence, probability that the blue marble was chosen both times 6/10.

What is the slope of the line which passes through (4, 5) and (0, 1)?
Answer:
slope = 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, 5) and (x₂, y₂ ) = (0, 1 )
m = [tex]\frac{1-5}{0-4}[/tex] = [tex]\frac{-1}{-1}[/tex] = 1

Chloe is making rice krispie treats with her friends and fills a 5 ¾ inch by 4 inch by 2 ½ inch pan to the very top. What is the volume of the rice krispie treats that the recipe makes?
Answer:
57 1/2 cubic inches
Step-by-step explanation:
Volume of the treat = length * width * height
Give
Length = 5 ¾ inch
width = 4inches
height = 2 ½ inches
Volume = 23/4 * 4 * 5/2
Volume = 23 * 5/2
Volume = 115/2
Volume = 57 1/2 cubic inches

Step-by-step explanation:
Can yall get me the volume calculations for the 3 shapes? Thank you! | Geometry
Figure 1
Name = Coneh = 4 unitsd = 8Since the diameter is 8, this cuts in half to the radius of r = 4. Plug the given values into the cone volume formula below
V = (1/3)*pi*r^2*h
V = (1/3)*pi*(4)^2*4
V = (64/3)pi ..... exact volume in terms of pi
V = (64/3)*3.14
V = 66.98667 .... approximate volume when using pi = 3.14
========================================================
Figure 2
Name = cylinderh = 4d = 8 which cuts in half to r = 4V = volume of cylinder
V = pi*r^2*h
V = pi*4^2*4
V = 64pi ..... exact volume
V = 64*3.14
V = 200.96 .... approximate volume when using pi = 3.14
========================================================
Figure 3
Name = rectangular prismb = 32h* = 12h = 4b and h* are dimensions along the bottom face, aka floor
h is the height or vertical dimension of the 3D room
V = volume of rectangular prism = volume of 3D room
V = length*width*height
V = (b)(h*)(h)
V = (32)(12)(4)
V = 1536 is the exact volume
There is no approximate volume for this figure because the result above is an integer.
========================================================
Combining the figures
Adding up the volumes for figures 1 through 3 gets us
(64/3)pi + 64pi + 1536 = (256/3)pi + 1536
The exact total volume in terms of pi is (256/3)pi + 1536
If we used pi = 3.14, then it leads to
(256/3)pi + 1536 = (256/3)*3.14 + 1536 = 1803.94667
The approximate total volume of all three figures combined is roughly 1803.94667 cubic units
