Answer:
y=4.5
Step-by-step explanation:
You just have to remember that the equation of a horizontal line is a constant function, meaning that no matter what values are entered into the system, the answer for Y will always be the same. So in this case the function will be y=mx+b, since m or the slope in a horizontal line is 0 "x" will also be 0, so y=b, in this case as we can see in the point we are given b=4.5, so y=4.5
does the equation 4(2x+3)=16x+12-8x have one solution, infinitely many solutions, no solution, or two solutions.
Answer:
Infinite number of solutions
Step-by-step explanation:
Use distributive property to eliminate the parenthesis on the left:
8 x + 12 = 16 x + 12 - 8 x
combine like terms on the right:
8x+ 12 = 8 x + 12
subtract 12 from both sides
8 x = 8 x (notice both sides are identical)
subtract 8 x from both sides
0 = 0
This is a true statement that takes place for whatever x-value we use in the original equation. Therefore, the equation has infinite number of solutions (any real number "x")

Step-by-step explanation:
For a science project, Daniel planted 51 flower seeds. Of those seeds, 12 did not grow at all. Of the seeds that did grow, 2/3 of them grew green tomatoes. How many green tomatoes grew?
a) 12
b) 8
c) 26
d) 13
Answer:
C. 26
Step-by-step explanation:
According to the question,
Daniel planted 51 seeds.
12 seeds did not grow at all,
Therefore, the number of seeds that grew are 51-12= 39
Then, from the 39 seeds that grew, 2/3 of them are green tomatoes.
So, to find out how many green tomatoes grew, we solve
2/3 * 39= 26.
Therefore, the amount of green tomatoes are 26.
The distance traveled, D in feet, is a function of time, t, in seconds, with
D=f(t)= t 3 +1
Find f(10), f'(10), and the relative rate of change f'/f at t=10. Interpret your answers in terms of distance travele
Answer:
1001 m/s
300 [tex]m/s^2[/tex]
0.299.
Step-by-step explanation:
Given that:
[tex]D=f(t)=t^3+1[/tex]
[tex]f(10)[/tex] means putting the value of [tex]t=10[/tex] in [tex]f(t)[/tex].
[tex]f(10) = 10^3+1=1001[/tex] [tex]m/s[/tex]
To find [tex]f'(10)[/tex], we need to find [tex]f'(t)[/tex] first.
Differentiating the equation of Distance [tex]D[/tex] w.r.to [tex]t[/tex]:
[tex]f'(t) = \dfrac{d}{dt}(t^3+1)= 3t^{3-1}+1 = 3t^2[/tex]
[tex]f'(10) = 3(10)^2=300[/tex] [tex]m/s^2[/tex]
Relative rate of change:
[tex]\dfrac{f'}{f}\ at\ t = 10 \Rightarrow \dfrac{300}{1001} \approx 0.299[/tex]
Explain how to find the slope of the line. And explain answer
Answer:
by using the slope incercept form: y=mx+b
this one is m=7/3 (m is the letter we use for the word slope btw) :)
Step-by-step explanation:
Find the equation of the tangent line. y=(x^2+x-2)^2 at (-1,4)
Compute the derivative of y = (x² + x - 2)² using the chain rule:
dy/dx = 2 (x² + x - 2) d/dx [x² + x - 2]
dy/dx = 2 (x² + x - 2) (2x + 1)
Evaluate the derivative at x = -1 :
dy/dx (-1) = 2 ((-1)² + (-1) - 2) (2 (-1) + 1) = 4
This is the slope of the tangent line to the function at (-1, 4).
Use the point-slope formula to get the equation for the tangent line:
y - 4 = 4 (x - (-1)) → y = 4x + 8
Given:3x-4=8 prove x=4
Hi!
Okay, so to prove that x = 4, all you have to do is insert 4 into the equation by replacing x with 4.
3x-4=8
3(4)-4=8
Now solve:
12-4=8
8=8
This is true, so x does equal 4.

A) Point A
B) Point B
C) Point C
D) Point D
Answer:
B
Step-by-step explanation:
D point is a representation of -(-3), Option D is correct.
What is Number system?A number system is defined as a system of writing to express numbers.
A number line is a picture of a graduated straight line that serves as visual representation of the real numbers
Every point of a number line is assumed to correspond to a real number, and every real number to a point
The points right to the integer zero are positive
The points left to the integer zero are negative
-(-3) is nothing but +3
The point D represents the 3
Hence, D point is a representation of -(-3), Option D is correct.

The weights, in pounds, of the cats in an animal adoption center are normally distributed. If a random sample of cats is taken and the confidence interval is (7.9,12.7), what is the margin of error?
Give a numerical response for your answer. For example, if you found that the margin of error was 2, you would enter 2.
Answer:
2.4
Step-by-step explanation:
Given that :
The confidence interval = ( 7.9 , 12.7 )
The Margin of error M.O.E = Interval width/2
where;
The interval width = UCL - LCL
The interval width = 12.7 - 7.9
The interval width = 4.8
∴
The Margin of error M.O.E = 4.8/2
The Margin of error M.O.E = 2.4
