Our principal has to travel from one city to the next city at an average speed of 50km/hr. Compute for the distance between 2 cities
Answers
Answer:
The answer is false or "impossible"
Step-by-step explanation:
Heres why I say this:
If the “average speed” in one hour make the car travel 50km, it means the speed could not be constant. So, it could be 90km/h during the first 30 minutes and 10km/h during the second 30 minutes. If this is the case, for example, in the next 12 minutes after the first hour, the car could be traveled 18km at 90km/h, completing 50 + 18 = 68km. The tricky word “average” makes it impossible to answer. Good try, but no cigar.

Answer:
y = -9 (negative 9)
Step-by-step explanation:
7 - 3(-9) =
7 - (-27) =
34
Hope this helped and pls mark brainliest!
Answer:
y = -9Explanation:
7 - 3y = 34
Simplify both sides of the equation
7 − 3y = 34
7 + −3y = 34
−3y + 7 = 34
Subtract 7 from both sides
−3y + 7 − 7 = 34 − 7
−3y = 27
Divide both sides by -3
−3y / -3 = 27 / -3
Simplify
y = -9

Given f(x) = x + 1 and g(x) = 3x – 5,
what are
the restrictions on the domain when f(x)/g(x)
Answers
Answer:
There will be an asymptote at [tex]x=\frac{5}{3}[/tex], meaning the domain is restricted from (-∞, [tex]\frac{5}{3}[/tex])U([tex]\frac{5}{3}[/tex], ∞).
Step-by-step explanation:
When finding domain restrictions for an equation that has a fraction, take the denominator and set it equal to 0. Then, solve for x:
[tex]3x-5=0[/tex]
[tex]3x=5[/tex]
[tex]x=\frac{5}{3}[/tex]
Then we can determine that there's an asymptote at [tex]x=\frac{5}{3}[/tex] but that is the only restriction.

Answer:
y = √(3² + 3²)
9 = √(5² + x²)
Step-by-step explanation:
Diagram 1:
Hypotenuse = y
Opposite = 3
Adjacent = 3
y² = 3² + 3²
y = √(3² + 3²)
y = √(9 + 9)
y = √18
Diagram 2:
Hypotenuse ² = known leg² + unknown leg²
Hypotenuse = 9
Known leg = 5
Unknown leg = x
9² = 5² + x²
9 = √(5² + x²)
9² = 5² + x²
9² - 5² = x²
x² = 81 - 25
x = √ 56

A line crosses through the point (3,10) and another point can be found on the line by going right 2 and down 7. find slope and y intercept
Answers
Answer:
y = [tex]\frac{-7x}{2}+\frac{41}{2}[/tex]
Step-by-step explanation:
We are given the point (3, 10).
The second point is 2 on the x-axis and -7 on the y-axis. So our second point is: (3 + 2, 10 - 7) which is (5, 3).
Our formula for slope is m = [tex]\frac{rise}{run}[/tex] = [tex]\frac{y2-y1}{x2-x1}[/tex]
So, our equation would be [tex]\frac{3-10}{5-3}[/tex] = [tex]\frac{-7}{2}[/tex]
Using the standard formula of a line, y = mx + b, we can substitute for the slope, m.
y = [tex]\frac{-7x}{2}[/tex] + b
Now, we can substitute a point on the line to determine the y-intercept:
Using the point (3, 10),
10 = [tex]\frac{-7(3)}{2}[/tex] + b
b = 10 + [tex]\frac{21}{2}[/tex]
b = [tex]\frac{41}{2}[/tex]
So our full equation is: y = [tex]\frac{-7x}{2}+\frac{41}{2}[/tex]
Complete the table using the equation y = 6x +3.
Answers
If x is 1, you’d have y = 6(1) + 3, so y = 9
If x is 2, you’d have y = 6(2) + 3, so y = 15
If they give you y and you need to solve for x, your equation can be changed to solve for x
y = 6x + 3
Subtract 3 from both sides
y-3 = 6x
Divide both sides by 6
x = (y - 3)/6
So if y is 21
x = (21-3)/6
x = (18)/6
x = 3

sandy found seashells and 119 starfish on the beach she gave 225 of the seashells to fred how many seashells does sandy niw have
Answers
Answer:
114?? Ummm I confused that's it......
After giving 225 of the seashells to Fred, then Sandy has -106 seashells now, which is determined by subtraction.
To calculate this, we subtract the number of seashells given to Fred from the initial number of seashells.
Seashells Sandy has now can be calculated as follows:
Seashells Sandy has now = Initial number of seashells - Seashells given to Fred
Therefore, we have:
= 119 - 225
Apply the subtraction operation to get
= -106
This negative sign indicates that there are not enough seashells
Therefore, after giving 225 of the seashells to Fred, then Sandy has -106 seashells now.

Alice drew a rectangle with a perimeter of 30 cm and an area of 56 cm2. Which dimensions match Alice's rectangle?
Answers
Answer:
The dimensions that match Alice's rectangle are 7 cm and 8 cm.
Step-by-step explanation:
The perimeter of the rectangle is given by:
[tex] P = 2(a + b) = 30 cm [/tex] (1)
Where a and b are the sides of the rectangle
Also, the area of the rectangle is:
[tex] A = a\times b = 56 cm^{2} [/tex] (2)
By solving equation (1) for a, we have:
[tex] a = 15 cm - b [/tex] (3)
Now, by entering equation (3) into (2) we can find one side of the rectangle:
[tex] 56 cm^{2} = (15 cm - b)\times b [/tex]
[tex] b^{2} - 15b + 56 = 0 [/tex]
Solving the above quadratic equation we have:
b₁ = 7 cm and b₂ = 8 cm
Now, the other side of the rectangle can be calculated with equation (3):
[tex] a = 15 cm - b_{1} = 15 - 7 cm = 8 cm [/tex]
or
[tex] a = 15 cm - b_{2} = 15 - 8 cm = 7 cm [/tex]
Taking the first solution (b₁) or the second (b₂), we find that the dimensions that match Alice's rectangle are 7 cm and 8 cm.
Therefore, the dimensions that match Alice's rectangle are 7 cm and 8 cm.
