Line g bisects line segment BC at Point H. BH = 4x and HC = 24. Find BC.
Answers
The function is a parabola U-shaped up... so it's vertex y-value is the lowest y-value of the function.
The inverse would just be the switching of the domain and range
Answer:
The length of BC is 48 units.
Step-by-step explanation:
Given information: Line g bisects line segment BC at Point H. BH = 4x and HC = 24.
It is given that line g bisects line segment BC at Point H. It means point H divides the line BC in two equal parts BH and HC.
[tex]BH=HC[/tex]
[tex]4x=24[/tex]
Divide both sides by 4.
[tex]x=6[/tex]
The value of x is 6.
[tex]BH=4x=6\times 4=24[/tex]
The length of BC is
[tex]BC=BH+HC[/tex] (Segment addition property)
[tex]BC=24+24=48[/tex]
Therefore the length of BC is 48 units.
What is the solution to 89+k=-42
Answers
We simplify the equation to the form, which is simple to understand
89+k=-42
We move all terms containing k to the left and all other terms to the right.
+1k=-42-89
We simplify left and right side of the equation.
+1k=-131
We divide both sides of the equation by 1 to get k.
k=-131.

Answers
The number can be arranged from least to greatest as 2.03<2.3<2.303<2.33.
What are decimal Numbers?A decimal is a number with a whole and a fractional portion. Decimal numbers are between integers and indicate numerical value for a whole plus some fraction of a whole. In fraction form, we may say there is one and one-half pizzas. This is represented in decimal form as 1.5 pizzas.
Let's write the numbers to the third decimal point. Therefore, we can write the numbers as,
2.303 = 2.3032.3 = 2.3002.33 = 2.3302.03 = 2.030Now, the numbers can be arranged as,
2.030 < 2.300 < 2.303 < 2.330
2.03 < 2.3 < 2.303 < 2.33
Hence, the number can be arranged from least to greatest as 2.03<2.3<2.303<2.33.

TheValue of a stock begins at $0.05/and increase by 0.01 each month write an equation representing the value of the stock v in any months m
Answers
the equation I got was: v=0.05+(0.01m)
The linear equation can be represented as a straight line on a graph. The equation for the given case is v = 0.05 + 0.01m.
What is a Linear equation?A linear equation is a equation that has degree as one.
To find the solution of n unknown quantities n number of equations with n number of variables are required.
Given that,
The value of stock at the beginning is $0.05,
And, its rate of increase for each month is 0.01.
Suppose the value of stock be v and the month be m,
Then, the increment in its value for any month m is $0.01m.
Now, the equation for the value of stock v at any month m can be written by summing its initial value to its increment value obtained for each month as,
v = 0.05 + 0.01m.
Hence, the equation representing the value of the stock v in any months m is given as v = 0.05 + 0.01m.

The function d = 10t signifies that you cover 10 miles of distance per hour.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
We have the following problem -
You ride your bicycle at a rate of 10 mi/h. the distance d (in miles) that you ride is given by the function d=10t.
We have the distance [d] as the function of time as -
d = 10t
The given equation id d = 10t. The slope of the line is 10. This means that you cover 10 miles of distance in 1 hour. The graph representing the function is plotted.
Therefore, the function signifies that you cover 10 miles of distance per hour.

a-b+2c=7
b+c=1
a-2b-3c=0
Answers
Equation 2) b + c = 1
Equation 3) a - 2b - 3c = 0
Subtract equation 3 from equation 1.
3) a - 2b - 3c = 0
1) a - b + 2c = 7
Subtract equations from one another.
-b - 5c = -7 {This will now be called equation 4)
Then, add equation 4 into equation 2.
4) -b - 5c = -7
2) b + c = 1
Add.
-4c = -6
Divide both sides by -4.
c = 3/2
Plug in 3/2 for c in the 2nd equation.
2) b + c = 1
b + (3/2) = 1
Subtract 3/2 from both sides.
b = 1 - 3/2
Simplify.
b = 1 - 1 1/2
Simplify.
b = -1/2
Plug in -1/2 for b in equation 1 so that we find the value of a.
*Remember : b = -1/2, c = 3/2
1) a + b + 2c = 7
Plug in -1/2 for b, and plug in 3/2 for c.
a + (-1/2) + 2(3/2) = 7
Simplify.
a - 1/2 + 3 = 7
Simplify.
a - 2 1/2 = 7
Add 2 1/2 to both sides.
a = 7 + 2 1/2
Simplify.
a = 9 1/2
So, a = 9 1/2, b = -1/2, c = 3/2

When the smaller of two consecutive integers is added to three three times the larger, the result is 23. find the integers?
Answers
if you make x the smaller number the next number will be (x+1).
x +3(x+1) = 23
x +3x +3 = 23
5x = 23 - 3
5x = 20
x = 20/5
x = 4
the smaller integer is 4 then the next is 5
The value of the integers can be obtained by solving the equation as 5 and 6 respectively.
What is a linear equation?A linear equation in two variable has the general form as y = ax + by + c, where a, b and c are integers and a, b ≠ 0.
It can be represented as a straight line on a graph.
Suppose the smaller integer be x.
Then, the larger one is x + 1.
As per the question, the following equation can be formed as,
x + 3(x + 1) = 23
⇒ 4x + 3 = 23
⇒ x = 5
Thus, the larger integer is 5 + 1 = 6.
Hence, the integers are obtained as 5 and 6 respectively.

A counterexample showing the conclusion 'All the marbles in the bag are black' as false.
A counterexample is a scenario where the premises are true but the conclusion is false, demonstrating the invalidity of an argument. In this case, to prove invalidity, a counterexample could be a situation where there is at least one marble in the bag that is not black. For instance, if there are three black marbles and one red marble inside the bag, the selection of three black marbles is still possible, but the conclusion that all marbles are black is false.
