Answer:
40
Step-by-step explanation:
h(x)= 4(x + 6)
Let x=4
h(4)= 4(4 + 6)
= 4(10)
= 40
Answer:
D
Step-by-step explanation:
So we have the function:
[tex]h(x)=4(x+6)[/tex]
To find h(4), substitute 4 for x. Thus:
[tex]h(4)=4(4+6)[/tex]
Add within the parentheses:
[tex]h(4)=4(10)[/tex]
Multiply:
[tex]h(4)=40[/tex]
The answer is D.
And we're done!
A clock that is set fifteen minutes fast is less precise than an identical clock
that keeps correct time.
TRUE OR FALSE
The statement that a clock that is set fifteen minutes fast is less precise than an identical clock that keeps correct time is false
How to determine the true statement?When a time is set away from the correct time, the time on the clock would be incorrect.
However, this has nothing to do with the precision of the clock.
This is so because precision deals with closeness of the time measurement to the original time
Since the time is ten minutes fast, it would not be less precise
Hence, the statement is false

In a geometric sequence, the 5th term is 9 and the 7th term is 36. Use the geometric
mean to find the 6th term.
Answer:
18
Step-by-step explanation:
you need to get from 9 to 36 in 2 steps by multiplying, so you need to find what gets 9 to 26 in one turn. 9*4=36, and because 4 is square we know you can multiply by 2 twice to get the same effect. 9*2=18. and just to make sure we can check that 18*2=36
If f(x) = x3, evaluate the difference quotient
f(6 + h) − f(6) h
Correct question is;
If f(x) = x³, evaluate the difference quotient: [f(6 + h) − f(6)]/h
Answer:
h² + 108h + 18
Step-by-step explanation:
We are given f(x) = x³
Thus;
f(6 + h) = (6 + h)³ = (36 + 12h + h²)(6 + h) = 216 + 72h + 6h² + 36h + 12h² + h³ = 216 + 108h + 18h² + h³
Then, f(6) = 6³ = 216
Thus;
[f(6 + h) − f(6)]/h = [216 + 108h + 18h² + h³ - 216]/h = (h³ + 108h + 18h²)/h
This gives;
h² + 108h + 18
Let f(x)=x^2−4x. Solve f(x)=−4.

0 = x^2 - 4x + 4
0 = ( x + 2) ( x - 2 )

Which shows the equation below written in the form ax2 + bx+c= 0?
2x2 - 2 = -5x - 1
Bring all the equation from the right side to the left.
2x² - 2 = - 5x - 1
2x² + 5x - 2 + 1 = 0 (take note that as you bring the number over you also have to flip the sign)
Therefore,
2x² + 5x + 1 = 0 (shown)
( this ans is similar to the form of ax² + bx + c = 0 )
The equation below written in the form ax² + bx +c= 0 is 2x² + 5x + 1 = 0
What is Quadratic equation?In algebra, a quadratic equation is any equation that can be rearranged in standard form as where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no ax² term.
Examples of quadratic equations are: 6x² + 11x – 35 = 0, 2x² – 4x – 2 = 0, 2x² – 64 = 0, x² – 16 = 0, x² – 7x = 0, 2x² + 8x = 0 etc.
given:
2x² - 2 = - 5x - 1
2x² + 5x + 1 = 0.

how to solve for a b and c
Answer:
a=40. b=140. c= 40
Step-by-step explanation:
b is congruent To 140 because of the vertical angles postulate that states two angles vertical from one another are congruent.
a is 40 because it is Supplementary to b Which means that the sum of a and b must add up to 180.
c is Congruent to a due to the vertical angles postulate

Answer:
First problem:
Limiting the Domain to [tex]x\leq 0[/tex] (option A in the list)
Second problem:
All the three statements are true, so pick option D)
Step-by-step explanation:
Recall that a function in order to have inverse needs to be a one-to-one function. In the case of the function they give you in the problem:
[tex]f(x)= 3x^2+1[/tex]
the graph corresponds to a parabola with vertex at x=0 and y=1 (0, 1), and since it has two branches that correspond to equal y-values for opposite pairs of x values, it doesn't satisfy the conditions for the existence of inverse. But if we limit the Domain of it considering just one half of the graph (for example limiting the Domain to the values to one side of the parabola's vertex, then this restricted function is one-to-one and we can find its inverse.
So the option of limiting the Domain to x-values smaller than or equal to zero, suggested in option A of the list of answers will do the job we need.
In the following problem, the three first statements are true for an inverse function, so pick option D that says that all previous statements are true.

-35x+85x-24=26 what is x
Answer:
x=1
Step-by-step explanation:
-35x+85x-24=26
Combine like terms
50x -24 = 26
Add 24 to each side
50x-24+24 =26+24
50x = 50
Divide each side by 50
50x/50 = 50/50
x=1
Answer:
x=1
Step-by-step explanation:
subtract 35 from 85 which would equal 50 and then add x
so 50x-24=26
add 24 to 26 because you want x by itself
which would equal 50
50x=50
divide by 50 on both sides
50/50=1
x=1

Answer: 40 peaches
Step-by-step explanation:
Let x represent (1/2) the peaches
and y represent (1/2) the strawberries
Peaches Strawberries Ratio
Alice: x - 3 y 1:4
Bryan: x y - 8 1:3
We can create a system of equations:
Alice: 4(x - 3) = y --> 4x - 12 = y
Bryan: 3(x) = y - 8
Substitute y = 4x - 12 into the Bryan equation:
3x = (4x - 12) - 8
3x = 4x - 20
-x = -20
x = 20
Therefore, Alice and Bryan each had 20 peaches, which means Bryan bought a total of 40 peaches.

George weighs 60 pounds less than his older brother. Together they weigh 240 pounds. How many pounds does George weigh?
Easy Algebra question!
Let's use "x" as a variable.
The equation would be x+x+60 = 240 with "x" being George's weight.
Subtract 60 from both sides and you get 2x = 180.
From there you divide both sides by 2, getting x=90.
"x" is George's weight, so he weighs 90 pounds.
ANSWER: 90 POUNDS
The weight of George is 90 pounds and the weight of George's brother is 150 pounds.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
George weighs 60 pounds less than his older brother.
Together they weigh 240 pounds.
Let George weigh be x and his brother weigh be y.
x + y = 240 ...1
x = y - 60 ...2
Then from equations 1 and 2, we have
2x = 180
x = 90
Then y will be
y = 90 + 60
y = 150

please help Solve: x² - 64 = 0
Answer:
x = plus or minus 8
Step-by-step explanation:
x² - 64 = 0
x² = 64
x = [tex]\sqrt{64}[/tex]
x = ± 8
Answer: Solve : x2+64 = 0
Subtract 64 from both sides of the equation :
x2 = -64
When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:
x = ± √ -64
In Math, i is called the imaginary unit. It satisfies i2 =-1. Both i and -i are the square roots of -1
Accordingly, √ -64 =
√ -1• 64 =
√ -1 •√ 64 =
i • √ 64
Can √ 64 be simplified ?
Yes! The prime factorization of 64 is
2•2•2•2•2•2
To be able to remove something from under the radical, there have to be 2 instances of it (because we are taking a square i.e. second root).
√ 64 = √ 2•2•2•2•2•2 =2•2•2•√ 1 =
± 8 • √ 1 =
