Answer:
x = 51/4 or x = 12.75
Step-by-step explanation:
(2x - 1)2 = 49
4x - 2 = 49
4x = 49 + 2
4x = 51
x = 51/4 or x = 12.75
Hope you are able to understand it!
Chloe prepared 28 kilograms of dough after working 7 hours. How much dough did Chloe prepare if she worked for 8 hours? Assume the relationship is directly proportional.
Answer:
Chloe prepared 32 kilograms if she worked for 8 hours.
Step-by-step explanation:
28 ÷ 7 = 4
4 kilograms per hour worked
4 × 8 = 32
Answer:
32 kilograms
Step-by-step explanation:
The proportion of kilograms of dough to the number of hours worked is [tex]\frac{28}{7}[/tex] which equals to 4 kilograms / hour.
You multiply 4 kilograms/hour by the number of hours she worked which is 8 hours so 4 kg/hour (8 hours) = 32 kilograms.

The two lines represent the amount of water, over time, in two tanks that are the same size. Which container is filling more quickly? EXPLAIN.
Answer:
A
Step-by-step explanation:
This is because line B has less water than A within the same time period. For example, lets say that each container had to be filled within 5 minutes. Container A would already be filled up within that time. Line B would be trailing behind a little.
Answer:
A
Step-by-step explanation:
because if we see from the graph:
let's say they are powered by x minutes
Thus A is filled while B is only a half
so container A is filling more quickly

What is the length of segment AC?
Answer:
It is 10 Units
Step-by-step explanation:
Mark me brainliest please :)
also this is EDG 2020
Answer:
10 units
Step-by-step explanation:
In the given figure, we may plot a point B with the coordinate pair (-5,-1).
Lets now draw a triangle ABC by connecting A and C with B perpendicularly.
We now know that,
AB = 5+3 = 8 units
CB=1+5= 6 units
[tex]As\ the\ drawn\ triangle\ is\ a\ right\ triangle, \ as\ angle\ CBA\ is\ 90\ degrees.\\Through\ Pythagoras\ Property,\ we\ may\ conclude\ that\ :\\ AB^{2} + BC^2 = CA ^2\\Hence, \\8^2+6^2=AC^2\\64+36=AC^2\\100=AC^2\\AC=10[/tex]
The equation F= 9/5C +32 relates temperature measured in degrees Celsius. C, to degrees Fahrenheit, F. Determine whether there is a proportional relationship between C and F.
Given:
The equation is
[tex]F=\dfrac{9}{5}C+32[/tex]
To find:
Whether there is a proportional relationship between C and F.
Solution:
If there is a proportional relationship between C and F, then the line of given equation passes through (0,0) and the equation must be true for (0,0).
Put F=0 and C=0 in the given equation.
[tex]0=\dfrac{9}{5}(0)+32[/tex]
[tex]0=0+32[/tex]
[tex]0=32[/tex]
This statement is not true because [tex]0\neq 32[/tex].
It means the line of given equation does not passes through (0,0). So, it s not a proportional relationship.
Hence, there is not a proportional relationship between C and F.

Find the equation of the tangent line. y=(9-x^2)^1/3 at (1,2)
Get the derivative:
y = (9 - x²)¹ʹ³
dy/dx = 1/3 (9 - x²)⁻²ʹ³ d/dx [9 - x²]
dy/dx = 1/3 (9 - x²)⁻²ʹ³ (-2x)
dy/dx = -2/3 x (9 - x²)⁻²ʹ³
Evaluate it at x = 1 :
dy/dx (1) = -2/3 • 8⁻²ʹ³
Since 8 = 2³, we have
8⁻²ʹ³ = 1 / 8²ʹ³ = 1 / (2³)²ʹ³ = 1 / 2² = 1/4
Then the tangent line has equation
y - 2 = 1/4 (x - 1) → y = 1/4 x + 7/4

Angle A and angle B are complementary. m Angle A = 54 and M angle B = 2x+2. What is the m angle B
Answer:
m=17
Step-by-step explanation:
Complementary means they add to equal 90 degrees.
1) 90-A=36
2)36=2x+2
3) Subtract 2 from both sides, 34=2x
4) Divide by 2 17=x

How to graph y=12-6x
Answer:
The answer will be listed below.
Step-by-step explanation:
This equation is in y=mx+b form, so to graph this equation, take the y-intercept which would be 12. Go on your graph and make twelve on the y-axis (you can go by two's or even six's). Then take your slope which would be -6 and use rise of run which would be down 6, since it's negative, and to the right one. Keep repeating this process until you ran out of space. Draw a line between the points and you have graphed a line.

4. The value of a copy machine is $8500 when it is purchased. After two years its value is $7475. What is its value after 8 years?
Answer:
3375 is the answer.
Step-by-step explanation: 8500- 1025=7475
so 1025 is every to years so we need to subtract 7475-1025-1025-1025-1025 so each 1025 is 2 yrs.

Jenna has a piece of paper that is 99 3/4 square inch in Area.
It is 10 1/2 inches long.
What is the width of the piece of paper in inches?
Answer:
Width is 9 1/2 in.
Step-by-step explanation:
My reasoning is that, since youve gotten the area (99 3/4), your asked to find the width. You have the length which is 10 1/2. In this situation youre expected to divide. What you divide is 99 3/4 by 10 1/2. If you calculate this, you get a quotient of 9 1/2. I’m not very ethical at explanations, but I hope you found it helpful somehow.

PLEASE PLEASE PLEASE HRLP ME Write the equation of a line in slope intercept form that has a slope of 2/9 and has a Y intercept of 2
Answer:
y=2/9x+2
Step-by-step explanation:
Answer:
y = [tex]\frac{2}{9}[/tex] x + 2
Step-by-step explanation:
Slope intersept form is y = mx +b
Y-intersept (b) is 2
Slope (m) is [tex]\frac{2}{9}[/tex]
Plug the slope(m) and Y-intersept (b) into y = mx +b : y = [tex]\frac{2}{9}[/tex] x + 2
