- 8a = 24
Answer:
a = -3
Step-by-step explanation:
Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other.
Divide -8 from both sides:
(-8a)/-8 = (24)/-8
a = 24/-8
a = -3
a = -3 is your answer.
Answer:
a = -3 to find this answer divide both sides by -8

2/sqrt(10) simplified
Answer:
20qrt/s / as in over
Step-by-step explanation:
To simplify 2/√(10), multiply the numerator and denominator by √(10) to get √(10)/5. This process removes the square root from the denominator.
To simplify the expression 2/√(10), we rationalize the denominator. This involves removing the square root from the denominator by multiplying the numerator and the denominator by the square root of 10.
Multiply the numerator and denominator by √(10):So, the simplified form of 2/√(10) is √(10)/5.
john is 3 times as old as susan. Mark is 5 years younger than john the sum of their ages is 30. how old is susan
Answer:
Susan is 5 years old
Step-by-step explanation:
Make a system of equations based on the info:
J=3S
M=J-5
J+M+S=30
Since we have the value of J, plug it in to either equation:
M=3S-5
Same deal with M:
3S+3S-5+S=30
7S-5=30
7S=35
S=5
So Susan is 5 years old

Find the value of x in the triangle shown below
The recursive formula to describe a sequence is shown below
a1=4
an=an-1+2n
State the first four terms of this sequence.
Given that the recursive formula for a sequence is [tex]a_n=a_{n-1}+2n[/tex]
The first term of the sequence is [tex]a_1=4[/tex]
We need to determine the first four terms of the sequence.
Second term:
The second term of the sequence can be determined by substituting n = 2 in the recursive formula.
Thus, we have;
[tex]a_2=a_{2-1}+2(2)[/tex]
[tex]a_2=a_{1}+2(2)[/tex]
[tex]a_2=4+4[/tex]
[tex]a_2=8[/tex]
Thus, the second term of the sequence is 8.
Third term:
The third term of the sequence can be determined by substituting n = 3 in the recursive formula.
Thus, we have;
[tex]a_3=a_{3-1}+2(3)[/tex]
[tex]a_3=a_{2}+2(3)[/tex]
[tex]a_3=8+6[/tex]
[tex]a_3=14[/tex]
Thus, the third term of the sequence is 14.
Fourth term:
The fourth term of the sequence can be determined by substituting n = 4 in the recursive formula.
Thus, we have;
[tex]a_4=a_{4-1}+2(4)[/tex]
[tex]a_4=a_{3}+2(4)[/tex]
[tex]a_4=14+8[/tex]
[tex]a_4=22[/tex]
Thus, the fourth term of the sequence is 22.
Hence, the first four terms of the sequence is 4, 8, 14, 22.
Wes wants to buy 3 pepper plants from the garden center. The regular price of a pepper plant
is $5. If Wes buys 3 plants, he can use a 20%-off coupon. If he buys 4 plants, he can use a
30%-off coupon Wes wants to know if buying 4 plants is less expensive than buying 3 plants.
What is the sale price of 3 pepper plants after a 20% discount?
Answer: 12
Step-by-step explanation: cuz i said so
The sale price of 3 pepper plants after a 20% discount is $12.
Explanation:To figure out the sale price of 3 pepper plants after a 20% discount, we first calculate 20% of the regular price. The regular price of one pepper plant is $5, so 20% of $5 is $1. Therefore, the sale price of one pepper plant is $5 - $1 = $4. As Wes wants to buy 3 plants, we multiply this sale price by 3, so the total price after discount for 3 plants is $4 * 3 = $12.
So, the sale price of 3 pepper plants after a 20% discount is $12.

What’s a linear function
Answer:
What is Linear Function? - Equation, Graph, Definition
A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2.
Step-by-step explanation:
The volume of a rectangular prism is 1,000^3 mm. Use the formula V = lwh to determine which of the statements are true. Choose all that apply
The prism could be a cube with a side length of 10 mm.
It is possible for the length to be 1,000 mm.
The length, width, and height must end in zero.
It is possible that the length is 2.5 mm.
(A) The prism could be a cube with a side length of 10 mm.
(B) It is possible for the length to be 1,000 mm.
(D) It is possible that the length is 2.5 mm.
Explanation:
Volume = l×w×h
where l is the length, w is the width and h is the height
It is possible that the length is 2.5 mm
Then volume = 2.5 × 10 ×40 = 1000 mm³
It is possible for length to be 1000 mm
Then volume = 1000 × 0.1 × 10 = 1000 mm³
The prism could be a cube of length 10 mm
Then volume = 10 × 10 × 10 = 1000 mm³

The product of 5 and an odd number will end in what value?
A) 0
B) 1
C)3
D)5
Answer:
D) 5
Step-by-step explanation:
If we multiply 5 and an odd number, the end value will not be 0, 1, and 3. For example,
5 × 1 = 5
5 × 9 = 45
Therefore, in both the product, the end value is 5 and not 0, 1, and 3.
Therefore, option D is correct.
If we multiply 5 by any of the odd number, we can get the end value of 5. The following examples are the valid reasons why we will get 5.
5 × 3 = 15
5 × 5 = 25
So, option A, B, and C are wrong.
Answer:
A) 0
B) 1
C)3

A circle has a circumference of 6. It has an arc of length 17/3. What is the central angle of the arc, in degrees?
Answer:
340 degrees
Step-by-step explanation:
So the key thing here is to notice that we are given the circumference which will allow us to find a value for the radius of the circle and hence the angle subtended by the arc (the central angle).
So the circumference of a circle = 2pi(r)
This means:
6 = 2pi(r)
Which means that
r = 6/2pi or r = 3/pi
Now we can use this value of r to find our angle in conjunction with the value of the arc length. So:
Arc length is defined by: length = θr
Where θ is our angle value.
So lets plug in:
[tex]\frac{17}{3} = (angle)\frac{3}{\pi }[/tex]
Multiply by pi to get:
[tex]\frac{17\pi }{3} = 3(angle)[/tex]
Divide by 3 to get that:
θ = 17pi/9
So if we convert that from radians to degrees we get 340 degrees.

Step-by-step explanation:
His formula makes the most sense to the sequence.
Evaluate each function at each of the four points.
Functions:
f(x) = x2 – 5x – 6
f(x) = 23 – 22 – 12
f(x) = 5.24
Points:
f(0)
f(2)
f(-1)
f(6)
1) f(0)= -6 , f(2)= -12, f(-1)= 0, f(6)= 0
2) f(0)= -12 , f(2)= -8 , f(-1)= -14 , f(6)= 168
3) f(0)= 5 , f(2)= 20, f(-1)= 2.5 , f(6)= 320
Step-by-step explanation:
1) The given function is f(x) = x² – 5x – 6.
To find the values of f(0) , f(2), f(-1), f(6) :
Substitute x=0 in f(x) = x² – 5x – 6
f(0) = -6
Therefore, f(0) = -6
Substitute x=2 in f(x) = x² – 5x – 6
f(2) = (2)² -5(2)-6
⇒ 4-10-6
⇒ 4-16
⇒ -12
Therefore, f(2) = -12
Substitute x= -1 in f(x) = x² – 5x – 6
f(-1) = (-1)² - 5(-1) -6
⇒ 1+5-6
⇒ 6-6
⇒ 0
Therefore, f(-1) = 0
Substitute x= 6 in f(x) = x² – 5x – 6
f(6) = (6)² - 5(6) -6
⇒ 36 -30 -6
⇒ 36-36
⇒ 0
Therefore, f(6) = 0
2) The given function is f(x) = x³– x²–12.
To find the values of f(0) , f(2), f(-1), f(6) :
Substitute x=0 in f(x) = x³– x²–12
f(0) = -`12
Therefore, f(0) = -12
Substitute x= 2 in f(x) = x³– x²–12
f(2) = (2)³ - (2)² -12
⇒ 8-4-12
⇒ 8-16
⇒ -8
Therefore, f(2) = -8
Substitute x= -1 in f(x) = x³– x²–12
f(-1) = (-1)³ - (-1)² -12
⇒ -1-1-12
⇒ -14
Therefore, f(-1) = -14
Substitute x= 6 in f(x) = x³– x²–12
f(6) = (6)³ - (6)² -12
⇒ 216 -36 -12
⇒ 216-48
⇒ 168
Therefore, f(6) = 168
3) The given function is f(x) = [tex]5.24^{x}[/tex]
To find the values of f(0) , f(2), f(-1), f(6) :
Substitute x=0 in f(x) = [tex]5.2^{x}[/tex]
f(0) = 5 × [tex]2^{0}[/tex]
Any number with power zero is 1.
f(0) = 5
Therefore, f(0) = 5
Substitute x=2 in f(x) = [tex]5.2^{x}[/tex]
f(2) = 5 × 2²
⇒ 5×4
⇒ 20
Therefore, f(2) = 20
Substitute x= -1 in f(x) = [tex]5.2{x}[/tex]
f(-1) = [tex]5\times2^{-1}[/tex]
⇒ 5 × 1/2
⇒ 5 × 0.5
⇒ 2.5
Therefore, f(-1) = 2.5
Substitute x= 6 in f(x) = [tex]5.2^{x}[/tex]
f(6) = [tex]5\times 2^{6}[/tex]
⇒ 5 × 64
⇒ 320
Therefore, f(6) = 320
