The blue line does not seem to be stretched or compressed.
A honeybee leaves the hive, traveling at a speed of 4 mph and returns 1 hour later. What was the distance traveled and the displacement of the honeybee in miles.
Answer:
Distance = 4 miles
Displacement = 0
Step-by-step explanation:
Given that :
Speed of honey bee = 4mph
Total travel time = 1 hour
Distance traveled by the honey bee:
Distance traveled = speed * time
Distance traveled = 4mph * 1 hour
Distance traveled = 4 miles
Displacement = 0 miles ; change in distance from initial position.
Since initial position of the honeybee is the beehive and its final position is the beehive. Hence, the change from its initial position is zero

Find X if f(x)=18x+26 and f(x) = 2x+10
Answer:
x = -1
Step-by-step explanation:
Start out by making the equations equal to each other since we are trying to find x (if x is the same for both equations, which it is for this problem due to the equations shown above).
18x + 26 = 2x + 10
Now that the equation is set up to find x, we need to get x by itself. Now subtract 2x on all sides to get all the x variables on the same side. Apply the same logic for the normal numbers by subtracting 26 on all sides to get the normal numbers on one side. You should end up with the numbers shown below for this step:
18x + 26 = 2x + 10
-2x -26 -2x -26
16x = -16
For the final step, remember that we want x by itself, so we have to divide both sides by 16 to get x by itself. After dividing both sides, you should end up with x = -1.
16x = -16
16 16
x = -1

Glenda makes an online purchase of 4 picture frames for $12.95 each and 4 mats for $5.89 each. The site says that taxes paid by the customer are 6.5% of the total purchase price. Shipping charges are based on the following table: Amount of Purchase Standard Shipping Express Shipping up to $50 $5.10 $7.00 $50 up to $100 $6.35 $8.20 $100 up to $200 $7.80 $11.60 $200 and over $10.50 $16.45 Glenda selects express shipping for her purchase and the company bills her credit card $91.86 for the total of the online purchase. Determine if Glenda has been billed correctly for her purchase. a. Glenda has been billed correctly. b. Glenda has not been charged enough for her purchase. c. Glenda has been over charged by $3.40 for her purchase. d. Glenda has been over charged by $3.80 for her purchase.
Answer:
C: Glenda has been over charged by $3.40 for her purchase
Step-by-step explanation:
The amount Glenda is to pay can be found by applying arithmetic
operations to the given parameters in the correct order.
The correct option is; c. Glenda has been overcharged $3.40 for her purchase.Reasons:
The price of each picture frame = $12.95
Number of picture frame purchased = 4
Price of each mat = $5.89
Number of mats purchased = 4
Total purchase price = $12.95 × 4 + $5.89 × 4 = $75.36
Total purchase price + Tax = $75.36 × 0.065 + $75.36 ≈ $80.26
Express Shipping charges for amount of purchase between $50 to $100 is given from the table as; $8.20
Total bill = Total purchase + Tax + Shipping
Therefore;
Total bill = $80.26 + $8.20 = $88.46
Amount the credit card is billed = $91.86
Amount of over charge = $91.86 - $88.46 = $3.40
Therefore, Glenda has been over charged by $3.40 for her purchase

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
141° is an exterior angle, thus
x + 24 + 2x + 12 = 141 , that is
3x + 36 = 141 ( subtract 36 from both sides )
3x = 105 ( divide both sides by 3 )
x = 35
-----------------------------------------------------------
(11)
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
2x - 9 + 3x + 2x = 180
7x - 9 = 180 ( add 9 to both sides )
7x = 189 ( divide both sides by 7 )
x = 27
Answer:
Unfortunately I can't do the first one, but the second one is easy
Step-by-step explanation:
To find X in the Q) 11:
1. The triangle is an equilateral traingles meaning angles add up to 180°
2. Add the numbers - 2x - 9 + 3x + 2x = 7x -9
3. Add 9 to 180 (your adding because you changed the side of the number) - 189 = 7x
4. Divide 7 by 189
Your answer is x = 27

There are 143 people in an audience. Out of this number 63 are female. What percent of people in the audience are male? Round to the neatest whole percent.
Answer: 56% of people in the audience are male.
Step-by-step explanation:
Given : Total people in the audience = 143
Number of females = 63
Number males = (Total people ) - (Number of females )
= 143 -63
= 80
The percent of people in the audience are male = [tex]\dfrac{\text{Number of males}}{\text{Total people}}\times100\%[/tex]
[tex]\dfrac{80}{143}\times100\%=55.94\%\approx56\%[/tex]
Hence, 56% of people in the audience are male.
anyone know what the answer is???(sorry if it’s unclear)
The laws of exponents I will be using are:
[tex](x^y)^z = x^{yz}[/tex], and [tex]x^y \cdot x^z = x^{y+z}[/tex].
For the first part, [tex](15^3)^3 \cdot 15^{-6} = 15^9 \cdot 15^{-6} = 15^3[/tex].
For the second part, [tex]15 \cdot (15^3)^2 \cdot (15^{-5})^2 = 15 \cdot (15^6) \cdot (15^{-10}) = 15^{1+6-10} = 15^{-3} = \frac{1}{15^3}[/tex].
find the x if the sum of three numbers is 180 and the numbers are 45,68,(3x+16)
Answer:
x = 17
Step-by-step explanation:
[tex]45 + 68 + (3x+16) = 180 \\ \\ 113 + 3x + 16 = 180 \\ \\ 129 + 3x = 180 \\ \\ 3x = 180 - 129 \\ \\ 3x = 51 \\ \\ x = \frac{51}{3} \\ \\ x = 17[/tex]

a slope-intercept equation of the line whose graph is perpendicular to
2x + 9y = 8 and has the y-intercept (0, -3)
Step-by-step explanation:
let eqn be y = mx + b.
2x + 9y = 8
9y = -2x + 8
y = -2/9 x + 8/9
since the lines are perpendicular, product of the slope of the two lines = -1.
hence,
m x -2/9 = -1
m = 9/2
sub (0, -3):
-3 = 9/2(0) + b
b = -3
therefore equation is: y = 9/2x - 3
