what is v?
Answer: see explanation
Step-by-step explanation:
The answer is very simple, you first do 3v + 2v which is 5v then you do 25 / 5 which is 5. This is your v (5). So the answer would be 5, you can ignore the 25+v this is there to confuse you.

The measure of an exterior angle of a triangle is equal to the sum of the measures of its two remote interior angles.
The three types of congruence transformations are rotation, reflection, and translation is TRUE.
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
A triangle will remain congruent if we rotate it by any angle in either a clockwise or counterclockwise manner.
If we transform by any amount either horizontal or vertical then it will remain the same so it will be congruent.
A triangle will remain the same if we mirror it on any axis, making it congruent.
Hence "The three types of congruence transformations are rotation, reflection, and translation is TRUE".

The equation in point-slope form of the line having the given slope m = 2 that contains the given point (4, -9) is 2x - y = 17
It is given that,
Slope is the measure of the steepness of a line.
Equation is the mathematical statement made up of two expressions joined together by the equal sign. For instance 3x - 5 = 16
The slope of a one point line = m = 2
The point through which the line passes = (4, -9)
We need to find the,
The equation in point-slope form of the line having the given slope that contains the given point
The formula which will be used,
(y-y1) = m(x-x1)
where, (x1,y1) = (4, -9) and m = 2
putting the values in the formula, we get
[y - (-9)] = 2. (x-4)
y + 9 = 2x - 8
y - 2x = -17
2x - y = 17
Hence, the equation in point-slope form of the line having the given slope that contains the given point is 2x - y = 17

Answer:

Step-by-step explanation:
We can solve for the unknown base using Pythagorean's theorem.
Remember Pythagorean's theorem goes as such:
[tex]a^2+b^2=c^2[/tex]
Where a and b are the two legs and c is the hypotenuse. We know one leg and the hypotenuse so we can insert our known values and solve for the unknown.
[tex]15^2+b^2=25^2\\225+b^2=625\\b^2=400\\b=20[/tex]
Or using trigonometry:
Note this is a 45-45-90 triangle, therefore all angles are known.
I'll use the sin function with the B angle.
[tex]sin(45)=\frac{b}{25} \\25*sin(45)=b\\17.67=b[/tex]
I'm assuming this problem was not made for trig, although the answer is still close.

What is symmetry ?Symmetry is defined as a proportionate and balanced similarity that is found in two halves of an object, that is, one-half is the mirror image of the other half. A 2D shape is symmetrical if a line can be drawn through it and either side is a reflection of the other.
Given:

According to given question we have,
This idea can be extended to congruences because congruent angles have the same measure.
Congruent angles are two or more angles that are identical to each other. Thus, the measure of these angles is equal to each other.

A store owner wants to develop a new snack mix by mixing chocolate and trail mix. how many pounds of chocolate costing $20.10 per pound should be mixed with 25 pounds of trail mix costing $2.80 per pound to create a mixture worth $8.41 per pound.
If a store owner wants to develop a new snack mix by mixing chocolate and trail mix, then the number of pounds of chocolate costing $20.10 per pound that should be mixed with 25 pounds of trail mix costing $2.80 per pound to create a mixture worth $8.41 per pound is equal to 11.99.
The pounds of chocolate needed to create a mixture worth $8.41 per pound can be calculated using an algebraic expression.
An algebraic expression can be defined as an expression consisting of both numbers and letters.
If x = the unknown pounds of chocolate
An algebraic expression can be given as,
20.10x + 2.80(25) = 8.41(x + 25)
Solving for x,
20.10x + 70 = 8.41x + 210.25
Rearranging,
20.10x - 8.41x = 210.25 - 70
11.69x = 140.25
x = 140.25 ÷ 11.69
x = 11.99
Hence, 11.99 pounds of chocolate costing $20.10 per pound should be mixed with 25 pounds of trail mix costing $2.80 per pound to create a mixture worth $8.41 per pound.

Answer:
The value of x is 12 if the value of f^-1(x) = 2.
Step-by-step explanation:
It is given that f(x) = 4(x + 1), which is an inverse function.
Now,
First of all, let us understand what is a function and an inverse function;
A function in mathematics from a set X to a set Y allocates precisely one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
On the other hand;
A function that may reverse into another function is known as an inverse function or anti function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. When a function is written as "f" or "F," its inverse is written as "f-1" or "F-1." Here, (-1) should not be confused with an exponent or a reciprocal.
Now, let us consider the first part of the question;
We have to calculate the value of x when f^-1(x) = 2 given that f(x) = 4(x+1) is the function;
=> f(x) = 4(x + 1)
=> 4(y + 1) = x
=> x = 4y + 4
=> y = (x - 4)/4
=> f^-1(x) = (x - 4)/4
Hence, f^-1(x) = (x - 4)/4 is the inverse of f(x).
Now, let us put the value of f^-1(x) = 2 in the equation so obtained;
=> f^-1(x) = (x - 4)/4
=> 2 = (x - 4)/4
=> 8 = (x - 4)
=> x = 12
Hence, the value of x is 12 if the value of f^-1(x) = 2.

Was wondering how to do this im confused.
A) The equation for a line that passes through the points (8, 2) and (6, 10) is:
y = -4*x + 34
B) line that has a slope of -2 and that passes through the point (-3, 5)
y = -2*x - 1
How to write the linear equations?
A) First we want to find the equation for a line that passes through the points (8, 2) and (6, 10).
Remember that a general linaer equation is of the form:
y = m*x + s
Where m is the slope and s is the y-intercept.
If the line passes through (a, b) and (c, d), then the slope is given by:
m = (d - b)/(c - a)
Then in this case, the slope is:
m =(2 - 10)/(8 - 6) = -8/2 = -4
Replacing that we get:
y = -4*x + s
To find the value of s we use the fact that the line passes through (8, 2), this means that:
2 = -4*8 + s
2 + 32 = s
34 = s
The linear equation is:
y = -4*x + 34
B) Now we want to find a line that has a slope of -2 and that passes through the point (-3, 5)
Here we already know the slope, so we can write:
y = -2*x + s
Again, to find the value of s, we replace the values in the point in the linear equation:
5 = -2*-3 + s
5 = 6 + s
5 - 6 = s = -1
We conclude that this linear equation is:
y = -2*x - 1
