Answer:
g(x) = - 3^xStep-by-step explanation:
Reflection over x-axis results in:
f(x) → - f(x) translationTherefore the new function is:
g(x) = - 3^x14 People fit comfortably in a 5 feet by 5 feet area. Use this value to estimate the size of a crowd that is 5 feet deep on both sides of the street along a 2-mile section of a parade route.
Answer:
29568
Step-by-step explanation:
Given that:
Length of road = 2 miles
Number of people who can fit in a area of 5 feet by 5 feet = 14
To find:
Number of people that can fit in the road of the given dimensions.
Solution:
Given that one side 2 miles wide and 5 feet deep.
First of all, we need to find number of 5 feet by 5 feet block that can be made in the given dimensions.
2 miles = 10560 feet
Number of blocks = [tex]\frac{10560}{5}[/tex] = 2112
Number of persons that can fit in one block = 14
Number of persons that can fit in 2112 blocks = 14 [tex]\times[/tex] 2112 = 29568
Therefore, the answer is: 29568

Acela Express, the fastest train between Washington D.C and Boston covers a distance of 455 miles in 7 hours. How many miles will the train travel in 4 hours?
Answer:
260 miles
Step-by-step explanation:
Given that:
Distance covered in 7 hours = 455 miles
Number of miles train will travel in 4 hours
Average travel speed per hour :
Distance traveled / time taken
455 miles / 7 hours
= 65 miles per hour
Number of miles traveled in 4 hours :
Average Speed per hour * time
(65 * 4) = 260 miles

11) 6x2+ 6x3
12) -6x 2 + (-6) x3
13) 5x - 8x
Answer:
11) 6x^2+ 6x^3 = 6.x.x+6.x.x.x
12) -6x^2 + (-6) x^3 = -6.x.x + (-6).x.x.x
13) 5x - 8x = 5.x -8.x
Step-by-step explanation:
Let us solve the question one by one.
11) 6x^2+ 6x^3
In order to convert the polynomial in the factored form, we see which factors are common in all terms in the polynomial.
[tex]6x^2 = 6.x.x\\6x^3 =6.x.x.x[/tex]
The factored form is:
[tex]= 6.x.x+6.x.x.x[/tex]
12) -6x^2 + (-6) x^3
Similarly, as 11
[tex]-6x 2 =-6.x.x\\-6x^3=-6.x.x.x[/tex]
The factored form is:
[tex]=-6.x.x+ (-6).x.x.x[/tex]
13) 5x - 8x
We can clearly see that there is only one common factor in both terms which is x
[tex]5x = 5.x\\8x = 8.x[/tex]
The factored form is:
[tex]=5.x-8.x[/tex]
Hence,
11) 6x^2+ 6x^3 = 6.x.x+6.x.x.x
12) -6x^2 + (-6) x^3 = -6.x.x + (-6).x.x.x
13) 5x - 8x = 5.x -8.x

Step-by-step explanation:
what is the slope of the line
2x+12y-192
Answer:
-1/6
Step-by-step explanation:
To get the slope we need the equation in the form y=mx+c, and m is the slope.
2x+12y=192
12y = -2x + 192
y = -2/12 x + 16
-2/12 is the slope but this can be simplified to -1/6

find the equation of a line which passes through (2 4) with a slope of ½
Answer:
The equation of the straight line is x - 2y +6 =0
Step-by-step explanation:
Explanation:-
Given a point ( 2, 4) and slope m = [tex]\frac{1}{2}[/tex]
The equation of the straight line passing through the point and having slope 'm'
y - y₁ = m ( x - x₁)
y - 4 = [tex]\frac{1}{2}[/tex] ( x - 2)
2( y -4) = ( x-2)
2 y - 8 = x -2
x - 2 y - 2 + 8 =0
x - 2y + 6 =0
The equation of the straight line is x - 2y +6 =0
The answer is:
y = 1/2x + 5
Work/explanation:
Since I have a point and the slope, I will write the equation in point slope form.
Point slope is
[tex]\sf{y-y_1=m(x-x_1)}[/tex]
where m = slope and (x₁, y₁) is a point on the line
Plug in the data
[tex]\sf{y-4=\dfrac{1}{2}(x-2)}[/tex]
Now let's simplify to slope intercept
[tex]\large\begin{gathered}\sf{y-4=\dfrac{1}{2}x+1}\\\sf{y=\dfrac{1}{2}x+1+4}\\\sf{y=\dfrac{1}{2}x+5}\end{gathered}[/tex]
Hence, the equation is y = 1/2x + 5.Multiply 2x(x^2-x+3)

2x+3x+1=21
Solve and show work
Answer:
x=4
Step-by-step explanation:
2x+3x+1=21
(2x+3x)+(1)=21
5x+1=21
5x+1=21
Step 2: Subtract 1 from both sides.
5x+1−1=21−1
5x=20
Step 3: Divide both sides by 5.
Answer:
x=4
Step-by-step explanation:
2x+3x+1=21
Simplify both sides of the equation.
2x+3x+1=21
(2x+3x)+(1)=21(Combine Like Terms)
5x+1=21
5x+1=21
Subtract 1 from both sides.
5x+1−1=21−1
5x=20
Divide both sides by 5.
5x /5 = 20 /5
x=4

Find the absolute value.
17.-|8|
18. |13|
19. |3 6/7|
20. |-134|
please help i dont know how to do this. I just went back to in person school and I told her it never taught me this. she argued with me and basically teach myself from pages of the math book. and I figured out some stuff but im confused with this part I'd love it if you'd help.
An absolute value is the positive value of the number between the vertical lines.
If the number in between the vertical lines is negative, the absolute value become a positive.
If the value in between the lines is already positive, it stays positive.
17. |-8| = 8
18. |13| = 13
19. |3 6/7| = 3 6/7
20. |-1.34| = 1.34
Answer:
17. 8
18.13
19. 3 6/7
20. 1.34
Step-by-step explanation:
The absolute value would just be the opposite of the original value.
y = 7x-6
what is the y-intercept?
Answer:
This is in slope intercept form
y = mx + b
m is the slope b is the .y intercept so the y intercept is -6
Step-by-step explanation:
Answer:
-6
Step-by-step explanation:
We know this because the equation is y=mx+b. M represents the slope and b represents the y-intercept. In this case, -6 is in the y-intercept’s place. Therefore, we know that -6 is the y-intercept.

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,260 ft Determine the flag's width and length if the length is 290 ft greater than the width.
Answer:
length= 710 width= 420
Step-by-step explanation:
As we consider a rectangle we can replace "length" with l and "width" with w so that the perimeter will be:
2l+2w= 2260
With the length as:
l= w+290
The length, substituted into the perimeter is:
2(w+290)+2w=2260
Distribute:
4w+580=2260
Subtract:
4w=1680
Divide:
w=420
To find the length, take the width and add 290:
420+290=710
l=710
Wesley wants to have at least $50 to spend each day of his 7-day vacation. He plans to save $30 each month for 12 months. Which of the following shows that Wesley will save enough money for his vacation? Choose all that apply.
Answer:
i cant choose any that applies to this question because there is no picture added to it and there are no choices to choose from. If i were to solve it though, it would be; yes, he will save enough money for his vacation.
Step-by-step explanation:
I know he would have enough--and in this case more than enough, because since he's planning to save $30 for a whole year just for $50, when he could simply make $60--which is in fact more than needed for his goal-- in just 2 months. If he were to stick with his plan though, he'd make $360. I got that by multiplying 30 by 12.
Write each percent as a decimal and as a fraction in simplest form. 36. 200% 37. 135% 38. 152% 39. 0.03% 40. 0.45%
Answer:
2.0 , 2/1.
1.35 , 1 7/20.
1.52, 1 13/25
0.0003, 3/10000
0.0045, 9/2000
Step-by-step explanation:
1.35 = 1 35/100 = 1 7/20
1.52 = 1 52/100 = 1 13/25
0.0045 = 45/10000 = 1 9/2000.
For the equation, decide if it is always true or never true.
2(x + 3) = 5x + 6 − 3x
Answer:
always true
Step-by-step explanation:
Given
2(x + 3) = 5x + 6 - 3x ← distribute left side
2x + 6 = 2x + 6
Since both sides are equal then any real value of x is a solution.
Thus the equation is always true
