Answer: C
Step-by-step explanation:
[tex]A = \frac{1}{2} (b+c)h\\[/tex] -> This is the original equation
[tex]\frac{A}{h} = \frac{1}{2} (b+c)\\[/tex] -> Divide by h on both sides
[tex]2\frac{A}{h} = b+c\\[/tex] -> Multiply both sides by 2
[tex]2\frac{A}{h}-b = c\\[/tex] -> subtract b from both sides

rotation, then reflection
rotation, then translation
Answers
Answer:
rotation, then translation
Step-by-step explanation:
The transformation that map triangle MNQ onto triangle PQN is rotation, then translation.
The given triangles;
Triangle MNQ Triangle PQNA translation of a triangle occurs when the triangle shifts up, or down, of left or right on the coordinate plane.
The reflection of a triangle occurs when the vertices of the triangle is flipped over the opposite side.
Since the triangle MNQ is rotated then shifted to the left to form the new triangle PQN, we can conclude that the transformation that map triangle MNQ onto triangle PQN is rotation, then translation.

y = ax² + bx + c
Plug in the three given points, then solve for a, b, c
(-3,0): 0 = 9a - 3b + c
(4,0): 0 = 16a + 4a + c
(0,-12): -12 = c
9a - 3b = 12
3a - b = 4
16a + 4b = 12
4a + b = 3
a = 1

[tex] m\widehat {WV} = 50\degree[/tex]
Step-by-step explanation:
Let O be the center of the circle.
[tex] m\angle VOU =m\angle TOU... (given) [/tex]
[tex] \therefore m\angle VOU =(5x + 10)\degree[/tex]
[tex] [\because m\angle TOU = (5x +10)\degree] [/tex]
[tex] m\widehat {TUV} = (5x +10)\degree + (5x +10)\degree [/tex]
[tex] m\widehat {TUV} = (10x +20)\degree [/tex]
[tex] m\widehat {SW} =m\widehat {TUV} [/tex]
[tex] (12x-2)\degree = (10x +20)\degree [/tex]
[tex] 12x-2 = 10x +20 [/tex]
[tex] 12x-10x = 2 +20 [/tex]

Suzanne can put up 20 feet of fencing in 64 minutes. How many minutes will it take her to put up 35 feet of fencing?
Answers
Answer:
112 minutes
Step-by-step explanation:
Suzanne can put up 20 feet of fencing in 64 minutes.
We need to find minutes it will take to put up 35 feet of fencing.
20 feet = 64 minutes
1 feet = (64/20) minutes
For 35 feet,
[tex]35\ feet=\dfrac{64}{20}\times 35\\\\=112\ minutes[/tex]
So, it will take 112 minutes to put up 35 feet of fencing.

You and a friend are racing each other to swim 500 meters. You complete 50 meters in 45 seconds. Your friend completes 150 meters in 2 minutes. Who won the race and by how much?? no links
Answers
Answer:
your friend by 50 seconds
Step-by-step explanation:
150 divided by 3 equals to 50 so you would also divide 120 minutes by 3 to get 40
You: 50 meters per 45 seconds
Friend: 50 meters in 40 seconds
50 times 10 equals 500 meters so we will multiply both number of seconds by 10
You:45*10=450
Friend: 40*10=400
450>400 so the friend swims the fastest
450-400= is 50 seconds
So the friend swims the fastest by 50 seconds

Given that x and y are positive integers and (x*2)+x(2^2)+(y*2^3)+(y*2^4)=42, what is the value of xy? PLEASE HELP!!!!!!
Note: Answer is not x=0, y=7 or y=0, x=7
Answers
Answer:
x = 3, y = 1
Step-by-step explanation:
If your question is this: 2x + 4x + 8y + 16y = 42
6x + 24y = 42
3x + 12y = 21
For x and y are positive integers, there is only 1 set of x = 3 and y = 1 is the solution (because x = 7 and y = 0 is excluded)
check: 6 + 12 + 8 + 16 = 42

Answers
Steps:
3.25x + 14 = 30.25
3.25x = 30.25 - 14
3.25x = 16.25
x = 16.25/3.25
x = 5
Check:
3.25x + 14 = 30.25
3.25(5) + 14 = 30.25
16.25 + 14 = 30.25
30.25 = 30.25 ✅

Plot and connect the points A (3, -3), B (-3, -2), C (-5, 1), D (-5, 4), E (-4 ,6), F (-2, 6), G (3, 2), and find the length of EF.
Answers
Given:
The points are A(3, -3), B(-3, -2), C(-5, 1), D(-5, 4), E(-4 ,6), F(-2, 6), G(3, 2).
To find:
The length of EF and plot each point on a coordinate plane and connect them.
Solution:
Plot the given point A(3, -3), B(-3, -2), C(-5, 1), D(-5, 4), E(-4 ,6), F(-2, 6), G(3, 2) on coordinate plane and connect them as shown in the below figure.
From the below graph it is clear that the length of EF is 2 units. We can verify this solution by using the distance formula.
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, the distance between E(-4 ,6) and F(-2, 6) is
[tex]D=\sqrt{(-2-(-4))^2+(6-6)^2}[/tex]
[tex]D=\sqrt{(-2+4)^2+(0)^2}[/tex]
[tex]D=\sqrt{(2)^2+0}[/tex]
[tex]D=2[/tex]
Therefore, the length of EF is 2 units.

Answer:

Step-by-step explanation:
The system of equations can be written in augmented matrix form as ...
[tex]\displaystyle\left[\begin{array}{cc|c}-\frac{1}{2}&3&-4\\-1&-1&-1\end{array}\right][/tex]
The value of x found by Cramer's rule is the ratio of two determinants. The numerator is the coefficient matrix with the x-column replaced by the constant column. The denominator is the coefficient matrix.
[tex]\displaystyle x=\frac{\left|\begin{array}{cc}-4&3\\-1&-1\end{array}\right| }{\left|\begin{array}{cc}-\frac{1}{2}&3\\-1&-1\end{array}\right|}=\frac{(-4)(-1)-(-1)(3)}{(-\frac{1}{2})(-1)-(-1)(3)}=\frac{4+3}{\frac{1}{2}+3}\\\\\boxed{x=2}[/tex]
Using the Cramer's rule, the value of x in the system of equation is 2
How to solve for x?The system of equation is given as:
-1/2x + 3y = -4
-x - y = -1
Represent the above equation as a matrix
[tex]\left[\begin{array}{cc}-1/2&3\\-1&-1\end{array}\right] \left[\begin{array}{c}-4&-1\end{array}\right][/tex]
Start by calculating the determinant of the matrix
|A| = -1/2 * -1 - 3 * -1
Evaluate
|A| = 7/2
To calculate x, we replace the first column by the last.
So, we have:
[tex]\left[\begin{array}{cc}-4&3\\-1&-1\end{array}\right][/tex]
Next, calculate the determinant of the matrix
|x| = -4 * -1 - 3 * -1
|x| = 7
The value of x is then calculated as:
x = |x|/|A|
This gives
x = 7 ÷ 7/2
Evaluate
x = 2
Hence, the value of x is 2
