Given f(x) = 4(x - 8), determine the value of f(10).
Answer:
f(10) = 8
Step-by-step explanation:
f(x) = 4(x - 8)
Let x = 10
f(10) = 4 ( 10-8)
= 4 ( 2)
= 8
Here, we are provided with a polynomial in x and it's general value in variable X is also given.
[tex]f(x) = 4( x - 8)[/tex]
We need to find the value of f(10)
For this, we need to substitute the value of x with 10, because we are required to find f(10)
Given polynomial, f(x) = 4(x - 8), Putting value of x
[tex]f(10) = 4(10 - 8)[/tex]
[tex]f(10) = 4(2)[/tex]
[tex]f(10) = \boxed{ \red{8}}[/tex]
This is our required answer !!

Step-by-step explanation:
pqrs is a rectangle with sides ps=5cm and pq =12cm find the length of qr ,sr and the two diagonals pr and qs.
tell the answer
PQRS is a rectangle.
PS = 5cm
PQ = 12cm
To Find:The length of qr ,sr and the two diagonals pr and qs.
Solution:Opposite sides of a rectangle are equal.
QR = PS = 5cm
SR = PQ = 12cm
By using Pythagoras Theorem, we get
PR = √PS^2 + SR^2
or, PR = √25 + 144
or, PR = √169
or, PR = 13cm
Diagonals of a rectangle are equal.
QS = PR = 13cm
Answer:QR = 5 cm
SR = 12 cm
PR = 13 cm
QS = 13 cm
On a map, 2 cm represents 30 mi. The actual distance between two towns
is 75 mi. What is the distance between the towns on the map? USE
NUMBERS ONLY*
Answer:
5 cmStep-by-step explanation:
step one:
Given that the scale of the map is
2cm to represent 30 miles
That is every 1 cm is 15 miles in reality
step one:
what we are solving for is the distance in cm on the map so,
1cm rep 15miles
xcm rep 75miles
cross multiply
Xcm= 75/15
X= 5 cm
hence on the map 75miles distance between the two towns is seen as 5 cm
Why can you not combine the 8a2 and 8a?
Answer:
you can't add or subtract numbers that don't have the same variable or the same exponent
Answer:
You cannot combine the terms [tex]8a^2[/tex] and [tex]8a[/tex] because they are not like terms, which are terms that consist of both the same power, and the same variable. Seen with the two terms given, they both share the same variable ([tex]a[/tex]), but not the same power ([tex]2[/tex]).
How do you solve this equation? (k/4 is a fraction)
5 = 12 + k/4
Subtract 12 from both sides
5 - 12 = k/4
Simplify 5 - 12 to -7
-7 = k/4
Multiply both sides by 4
-7 * 4 = k
Simplify -7 * 4 to -28
-28 = k
Switch sides
k = -28

Answer:
the mean is 50
Step-by-step explanation:
add up all the numbers which equals 300 then divide but the amount of numbers in this is 6 so that gives you 50
Answer:
50 is the mean
Step-by-step explanation:
When it ask for mean it ask you to add up all the numbers and divide by how many numbers their are. Their 6 numbers added together to make the total of 300.
49+51+49+51+51+49 = 300

What is the midpoint of points (1,1) and (-6,-8)
Answer:
(-2.5, -3.5)
Step-by-step explanation:
In order to find midpoint, you must add both x coordinates then divide by two and add both y coordinates then divide by two.
1 + (-6) = -5
-5/2 = -2.5
1 + (-8) = -7
-7/2 = -3.5
Tyler and Han is trying to solve this system by substitution:
x + 3y = -5
9x + 3y = 3
Tyler's first step is to isolate x in the first equation to get x = -5 - 3y. Hans first step is to isolate 3y in the first equation to get 3y = -5 - x show that both first steps can be used to solve the system and will yield the same solution.

round 9.69 to the nearest whole number
Rounding 9.69 to the nearest whole number gives us 10.
Given that we need to round the decimal number 9.69 to the nearest whole number,
To round 9.69 to the nearest whole number, we look at the decimal part of the number, which is 0.69.
Since the decimal part is greater than or equal to 0.5, we round the whole number up to the next higher number. In this case, 9.69 is closer to 10 than to 9, so we round it up to 10.
Therefore, rounding 9.69 to the nearest whole number gives us 10.

6x^2=32x+24 Need help learning factoring please put work so I can understand
Answer:
I do not sorry
Answer:
2 • (x - 6) • (3x + 2)
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2".
STEP 1 : Equation at the end of step 1
((2•3x2) - 32x) - 24
STEP 2 : Pulling out like terms
Pull out like factors :
6x2 - 32x - 24 = 2 • (3x2 - 16x - 12)
Trying to factor by splitting the middle term
Factoring 3x2 - 16x - 12
The first term is, 3x2 its coefficient is 3 .
The middle term is, -16x its coefficient is -16 .
The last term, "the constant", is -12
Step-1 : Multiply the coefficient of the first term by the constant 3 • -12 = -36
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is -16 .
-36 + 1 = -35
-18 + 2 = -16 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -18 and 2
3x2 - 18x + 2x - 12
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (x-6)
Add up the last 2 terms, pulling out common factors :
2 • (x-6)
Step-5 : Add up the four terms of step 4 :
(3x+2) • (x-6)
Which is the desired factorization
Final result : 2 • (x - 6) • (3x + 2)

round 27.68 to the nearest tenth
Answer:
27.7
Step-by-step explanation:
For this problem, we will simply use standard rounding conventions to round the number to the nearest tenth.
If the number after the target, the hundreths place in this case, is between 0 and 4, we won't change the tenths place. If the number is between 5 and 9, we will increment the tenths place by one.
So for our number, 27.68, 8 is between 5 and 9 so we will increment the tenths place by one for the round.
Hence, our rounded answer for the nearest tenth is 27.7.
Cheers.
