Answer:
(1,5)
Step-by-step explanation:
Substitute the first equation into the second:
3x + 2(4x+1) = 13
3x + 8x + 2= 13
11x = 11
x = 1
y = 4(1) + 1 = 5

Write a number with one decimal place, that is bigger than 3 2/3
but smaller than 4
Answer:
Since 15 is greater than 8, the correct expression will be:
15 > 8
Since 4 is less than 134, the correct expression will be:
4 < 134
Since 3 is less than 5, the correct expression will be:
3 < 5
Since 351 is greater than 215, the correct expression will be:
351 > 215
Step-by-step explanation:
The greater a decimal is, the closer it is to one whole. The smaller a decimal is the farther it is from one whole. The first thing you need to look at is the digit number in each decimal. These each have two digits in them, so you can compare them right away

Please help me I’ll give you 100 points
Answer and Step-by-step explanation:
So, you would do 100 times 31.8, which is 3180, that'll be the area of the rectangle.
Now, the semicircles. They together form a circle.
So, we do pi times d (diameter), which is 3.14 times 31.8 = 99.852
Now we add them together.
99.852 + 3180 = 3279.85 (rounded to the nearest hundredth of a meter)
The rectangle area is 3180.
The Semi circles' combined area is 99.85.
The total area of the figure is 3279.85.
I hope this helps! Have a great day!

Answer:
3973.82Step-by-step explanation:
to understand thisyou need to know about:geometryPEMDASlet's solve:there are a rectangle and a full circleaccording to the question
the area of full shape
=[tex]\text{area of the rectangle+the area of the full circle}[/tex]
=(100×31.8)+(π×(31.8/2)²)
=3180+(3.14×(15.9)²
=3180+(3.14×252.81)
=3180+793.8234
=3973.8234
=3973.82

What is the simplified expression for the expression below? -1(2x + 3) - 2(x - 1) O 4x+ O 4x - 2 o 4x + 2 0 4x -
Given:
The expression is:
[tex]-1(2x+3)-2(x-1)[/tex]
To find:
The simplified form of the given expression.
Solution:
We have,
[tex]-1(2x+3)-2(x-1)[/tex]
Using distributive property, we get
[tex]-1(2x+3)-2(x-1)=-1(2x)-1(3)-2(x)-2(-1)[/tex]
[tex]-1(2x+3)-2(x-1)=-2x-3-2x+2[/tex]
On combining like terms, we get
[tex]-1(2x+3)-2(x-1)=(-2x-2x)+(2-3)[/tex]
[tex]-1(2x+3)-2(x-1)=-4x-1[/tex]
Therefore, the simplified form of the given expression is [tex]-4x-1[/tex].

Step-by-step explanation:
[tex]y=-3(x^2+10x+25)-1\\ \\ y=-3x^2-30x-76\\ \\ dy=-6x-30\\ \\ d^2y=-6\\ \\ \text{Since the second derivative is always negative, when the first derivative is equal to zero the function will be at a global maximum.}\\ \\ dy=0=-6x-30\\ \\ x=-5\\ \\ f(-5)=-1\\ \\ \text{So the global maximum occurs at the point (-5,-1)[/tex]

Answer:
L= 90, M=53, K=37
Step-by-step explanation:
Tilt your phone/computer to the right, and you'll see the 90° angle for L. Now you're left with two more, and just compare which angle is bigger, K or M. M is bigger, so you apply the bigger number out of the you got which is 53. Now no doubts, K is 37.

1. f(x)=1/4x + 4
2. y=1/2x + 4
3. y=2x + 4
4. f(x)= - 2/3x + 4
Answer:
3. y=2x + 4
Step-by-step explanation:
We know that b is 4 because of the point (0,4)
Now count the slope by using rise over run
We go up 2 and over 1 so the slope is 2
The value of y varies directly with x, and y = -2 when x = -4. Find y when x = 8.
Answer:
y = 4
Step-by-step explanation:
8 ÷ -4 = -2
so, multiply each side by -2
-2 x -2 = 4
when x = 8, y = 4
Wayne spends 1/6th of an hour walking his dog. How much time does Wayne spend walking his dog in a week? *
Answer:
10 minutes
Step-by-step explanation:
This is somewhat of a trick question and also incomplete.
Assuming he walks his dog 1/6th of an hour each week, he walks his dog 10 minutes per week.
If this is incorrect please tell me the complete question
Ten subjects are being studied to test the effectiveness of itch relief for three types of medication: A, B, and C. Using a 10-point scale, the researcher calculates the subjects' amount of itching
before treatment compared with the amount of itching after treatment. The response variable is the itch rating after one hour of treatment. Previous studies have shown the effects of
treatment may vary based on a subject's pain resistance. How should the subjects be blocked? Explain. (4 points)
They should be blocked alphabetically so the subjects are as different as possible.
They should be blocked by age because older subjects tend to itch more.
They should be blocked by gender because female subjects tend to itch more.
They should be blocked by pain resistance so the subjects are as similar as possible.
O Blocking should not be used in this experiment.
Answer: Choice D
They should be blocked by pain resistance so the subjects are as similar as possible.
============================================================
Explanation:
The process of blocking in statistics is where we group up people in blocks, and each block is determined by a characteristic of some sort. In this case, we're grouping people up by pain resistance level. Those very resistant to pain will be in one group, while those who easily feel pain will be in another block, and so on. It might be effective to have a pain scale and sort people by that.
Blocking is done so that we eliminate unwanted variability. We are testing the effectiveness of the itching cream, so all we care about is if the itch reduces or not. We aren't worried about the levels of pain. However, it says that "Previous studies have shown the effects of treatment may vary based on a subject's pain resistance". So we group up the people by pain tolerance to help eliminate the variability of pain tolerance levels.
This is why choice D is the final answer.
-------------
Extra info:
Choice A is false because a person's name doesn't have anything to do with if the treatment works or not.Choice B is false because we weren't given any info to indicate it being true. It may be true, but we simply don't have enough info to confirm it. Choice C is false for similar reasons as choice B.Answer:D
Step-by-step explanation:
This is due to the question explicitly stating how the previous studies have shown the effects of treatment may vary based on a subjects pain resistance. This leads to the only option that relates to the study's background, D
