Solve the following equation algebraically: x squared = 50
Answers
Answer:
x = ±5sqrt(2)
Step-by-step explanation:
x^2 = 50
Take the square root of each side
sqrt(x^2) = ±sqrt(50)
x = ±sqrt(25*2)
We know that sqrt(ab) = sqrt(a) sqrt(b)
x = ±sqrt(25)*sqrt(2)
x = ±5sqrt(2)

If x and y are in direct proportion and y is 45 when xx is 15, find y when x is 4.
Answers
Answer:
y = 12
Step-by-step explanation:
the equation is
y = 3x
You find the constant or proportionality by put y/x
(15,45) is in the form (x,y) The x is 15 and the y is 45. Put this in the form y/x and you get 45/15 or 3. 3 is the constant of proportionality.
y = 3x
y = 3(4)
y = 12

show that the (5,5),(5,0),and (0,0) are the vertices of an isosceles triangle.
Answers
An isosceles triangle has 2 sides that are equal.
I plotted these points. See attached screenshot.
The first side's distance is 5. You can just count those units along the x axis. (0,0) and (5,0) share the same y coordinate, so the difference in x coordinates is 5-0 = 5.
The next sides's distance is also 5. You can count that distance on the coordinate plane. (5,5) and (5,0) share the same x coordinate, so the difference in y coordinates is 5-0 = 5.
These two sides make a right triangle and are equal length. This is an isosceles right triangle.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

It can be 12 because six times four is 24 and then 24 dived by 2 is 12, but it can also be 48 because four times 6 is 24 and then 24 times two is 48, but it can also be 36 because four times two is 6 and then six times six is 36. I think it is 48 though. I hoped this helped :)

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.
b) The correct expression is given as follows: -8.6b + 28.
How to simplify the expression?The expression in the context of this problem is defined as follows:
(-3.78b + 12) - (4.82b - 16).
The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:
-3.78b + 12 - 4.82b + 16.
This is the step where Maddie made the first error.
Then, to simplify the expression, we combine the like terms, as follows:
b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.

Answers
Answer:
A
Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A
