Answer:
3x + 8 is equal to 14 when x = 2.
Step-by-step explanation:
To evaluate the expression 3x + 8 when x = 2, we simply subsititute the value of x into the expression. We can write this expression as the function:
f(x) = 3x + 8
And we can evaluate the function when x = 2 by simply plugging in the value 2 for x:
f(x) = 3x + 8
f(2) = 3(2) + 8
f(2) = 6 + 8
f(2) = 14
Hence, the expression 3x + 8 is equal to 14 when x = 2.

89-11v_<7v-55
Answer:
v ≤ 8
Step-by-step explanation:
89-11v≤7v-55
-11v-7v≤ -55-89
-18v ≤ -144
divide Both sides by -18
-18v/-18 ≤ -144/-18
v ≤ 8

Solve this inequality: 4.2x+5.6<7.2-8.3x please give the steps.
Answer:
[tex]x<\frac{16}{125}[/tex]
Step-by-step explanation:
First we will multiply everything by 10 to get rid of the decimals.
[tex]4.2x*10+5.6*10<7.2*10-8.3x*10\\42x+56<72-83x[/tex]
Subtract 56 from both sides:
[tex]42x+56-56<72-83x-56\\42x<-83x+16[/tex]
Add 83x to both sides:
[tex]42x+83x<-83x+16+83x\\125x<16[/tex]
Divide both sides by 125:
[tex]\frac{125x}{125}<\frac{16}{125}\\x<\frac{16}{125}[/tex]

Liliana noted that the temperature was 45 degrees when she woke up. At noon she started recording the increase in degrees from the morning temperature.
A histogram titled Temperature has time of day on the x-axis and increase in degrees on the y-axis. 12 to 2 pm is 12 degrees; 2 to 4 pm is 18; 4 to 6 pm is 24; 6 to 8 pm is 20; 8 to 10 pm is 14; 10 to 12 am is 5.
Which statement most reasonably explains the hours after the peak increase in temperature?
The temperature always rises after a peak.
The temperature increase went down because the thermometer’s battery was losing power.
The temperature increase went down because it became cooler as the sun went down for the night.
The temperature rose after the peak when the sun came out from behind a cloud bank.
Answer: C
Step-by-step explanation:
The temperature increase went down because it became cooler as the sun went down for the night.

What is the division rule for 2?
Answer:
The Rule for 2 : Any whole number that ends in 0, 2, 4, 6, or 8 will be divisible by 2. This is the number four hundred fifty-six thousand, seven hundred ninety-one, eight hundred twenty-four. We can tell if 2 divides into this number without a remainder by just looking at the last digit.

Help 10 points 30 minutes to answer
Answer:
The first answer choice.
Answer choice A.
Step-by-step explanation:
The domain of a function would be the set of all possible x-values of that function.
Since we are looking for the domain, the set of the possible x-values, we can eliminate any answer choices that are a set of y-values. B and D are eliminated.
From what we can see in the table, the possible x-values of the function are -6, -1, 0 and 3. Although C does include these values in the set, it also includes many other values. As we can see, answer choice A includes the x-values given in the table and only those values. Therefore, answer choice A is the correct answer.
I hope you find my answer and explanation helpful. Happy studying.
The area of a square field is 42025 m square. Find the perimeter of the field. Can you explain and say it answer both pls
Answer:
Step-by-step explanation:
Answer:
820 m
Step-by-step explanation:
given:
The area of a square field is 42025 m square.
Find:
perimeter of the field.
solution:
Area of square = s² where s = side of square; A = 42,025 m²
plug in values into the formula:
[tex]\sqrt{42,025}[/tex] = s² ------square root
s = 205 m ---------length of each side of a square
solve for Perimeter:
Perimeter = 4 times the sides
= 4 x 205m
= 820 m
therefore, the perimeter of a square field is 820 m

27×5= 135
Answer:
Truefo example: 3•3 = 9 (=2•4+1) 5•7 = 35 (=2•17+1) 11•13 = 143 (=2•71+1)Step-by-step explanation:
If k is any integer then 2k is even number and 2k+1 is odd number
If n is any other integer then 2n+1 is also some odd number
Their product:
(2k + 1)(2n + 1) = 2k•2n + 2•1k + 1•2n + 1•1 = 2(2kn + k + n) + 1
k,n are integers so 2kn also is integer.
Sum of integers is integer too, so if we name 2kn+k+n = z, then product of any two odd integers is 2z+1 which is an odd number.

Which transformation can be applied to the blue figure to create the red figure? Photo above
AB = 6x + 2 and
BC = 5x + 3
Find AC.
Answer:
AC = 3x + 3 (answers may vary)
Step-by-step explanation:
AB = 6x + 2
Answers may vary for this question,
Let's say that,
B = 4x + 1
So that means that,
A = 2x + 1
BC = 5x + 3
Since we chose
B = 4x + 1,
we must subtract B from BC to get C,
C = x + 2
Now we add A and C to get AC,
A = 2x + 1
C = x + 2
AC = 3x + 3

7. 243
Hope this helps!
The required 7th term in the given geometric sequence would be 243.
What is geometric series?The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The sequence given in the question follows as:
1/3, 1, 3, 9, . . .
This sequence follows the pattern of a geometric progression, where each term is obtained by multiplying the previous term by a fixed number, called the common ratio.
The common ratio for this sequence is 3.
To find the nth term in a geometric progression, you can use the formula:
aₙ = arⁿ⁻¹
Where a is the first term, r is the common ratio
Plugging in the values for this sequence, we have:
[tex]a_7 = 1/3 \times 3^(7-1) = 1/3 \times 3^6[/tex]
= 1/3 x 729 = 729/3 = 243
Therefore, the 7th term in the sequence is 243.

Mr. Hernandez has 41 feet of rope to enclose a pentagonal grazing area for his sheep. Sides of the pen are represented by: x, 7 - 5x, 3x - 2, 3x + 4, 5-3x. Which inequality could be used to find the possible perimeters of the grazing area?
Answer:
Option (B)
Step-by-step explanation:
Length of the rope Mr Hernandez has = 41 feet
He wants to enclose an area in the shape of a pentagon.
Therefore, minimum length of the rope required = perimeter of the pen
Perimeter of the pentagonal pen = Sum of the measures of all five sides of the pen
Perimeter = x + (7 - 5x) + (3x - 2) + (3x + 4) + (5 - 3x)
= (-x + 14)
Now the length of the rope should be more than and equal to the perimeter of the pen to cover.
41 ≥ (-x + 14)
Or
-x + 14 ≤ 41
Therefore, Option (B) will be the answer.
