Answer:
The correct option is;
Up, rotate 90 degrees counterclockwise, down and right, rotate 90 derees clockwise, left
Step-by-step explanation:
The motion of the shape are
1) The shape is moved up from the initial position
2) The shape is then rotated 90 degrees in the reverse direction of the motion of the clock
3) The shape then moves two motion of coming down and moving right in one step
4) The shape is then rotated 90 degrees in the clockwise direction
5) In the final step, the shape is moved left.
Answer Scale Factor Question
Answer:
scale factor = [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Given
A(4, - 2 ) → A'(1, - [tex]\frac{1}{2}[/tex] )
To determine the scale factor compare the ratio of corresponding coordinates, image to original, that is
scale factor = [tex]\frac{1}{4}[/tex] = [tex]\frac{-\frac{1}{2} }{-2}[/tex] = [tex]\frac{1}{4}[/tex]
what is an equation of a line in a point-slope form that passes through (1,-7) and has a slope of -2/3?
Answer:
y+7=[tex]-\frac{2}{3}[/tex](x-1)
Step-by-step explanation:
slope of -2/3, so m=-2/3
point slope form=y-[tex]y_{1}[/tex]=m(x-[tex]x_{1}[/tex])
plug in your slope as well as your x and y values from your point
y-(-7)=(-2/3)(x-1)
y+7=[tex]-\frac{2}{3}[/tex](x-1)
15(x -20)-21= -3(x+1)+6
Answer:
x = 18
Step-by-step explanation:
Solve for x:
15 (x - 20) - 21 = 6 - 3 (x + 1)
Hint: | Distribute 15 over x - 20.
15 (x - 20) = 15 x - 300:
15 x - 300 - 21 = 6 - 3 (x + 1)
Hint: | Group like terms in 15 x - 300 - 21.
Grouping like terms, 15 x - 300 - 21 = 15 x + (-300 - 21):
15 x + (-300 - 21) = 6 - 3 (x + 1)
Hint: | Evaluate -300 - 21.
-300 - 21 = -321:
15 x + -321 = 6 - 3 (x + 1)
Hint: | Distribute -3 over x + 1.
-3 (x + 1) = -3 x - 3:
15 x - 321 = -3 x - 3 + 6
Hint: | Group like terms in -3 x - 3 + 6.
Grouping like terms, -3 x - 3 + 6 = (6 - 3) - 3 x:
15 x - 321 = (6 - 3) - 3 x
Hint: | Evaluate 6 - 3.
6 - 3 = 3:
15 x - 321 = 3 - 3 x
Hint: | Move terms with x to the left hand side.
Add 3 x to both sides:
15 x + 3 x - 321 = (3 x - 3 x) + 3
Hint: | Look for the difference of two identical terms.
3 x - 3 x = 0:
15 x + 3 x - 321 = 3
Hint: | Group like terms in 15 x + 3 x - 321.
Grouping like terms, 15 x + 3 x - 321 = (15 x + 3 x) - 321:
(15 x + 3 x) - 321 = 3
Hint: | Add like terms in 15 x + 3 x.
15 x + 3 x = 18 x:
18 x - 321 = 3
Hint: | Isolate terms with x to the left hand side.
Add 321 to both sides:
18 x + (321 - 321) = 321 + 3
Hint: | Look for the difference of two identical terms.
321 - 321 = 0:
18 x = 3 + 321
Hint: | Evaluate 3 + 321.
3 + 321 = 324:
18 x = 324
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 18 x = 324 by 18:
(18 x)/18 = 324/18
Hint: | Any nonzero number divided by itself is one.
18/18 = 1:
x = 324/18
Hint: | Reduce 324/18 to lowest terms. Start by finding the GCD of 324 and 18.
The gcd of 324 and 18 is 18, so 324/18 = (18×18)/(18×1) = 18/18×18 = 18:
Answer: x = 18

3 = q/11 i need it real quick
Answer:
[tex]q=33[/tex]
Step-by-step explanation:
So we have:
[tex]3=\frac{q}{11}[/tex]
Multiply both sides by 11:
[tex]11(3)=(11)\frac{q}{11}[/tex]
The right side cancels:
[tex]11(3)=q[/tex]
Multiply the left:
[tex]33=q[/tex]
Thus, the value of q is 33.
Answer:
q = 33
Step-by-step explanation:
3 = q/11 multiply both side by 11
3 * 11 = [tex]\frac{q}{11}[/tex] * 11

On a number line, point C is located at -4 and point D is located at 6. At what point must P be located so that the directed line segment from C to D will be partitioned in a 2:3 ratio?
●-2
●0
●2
●4
Answer:
0 is the answer
Step-by-step explanation:
The position of point P is at 0 on number line.
What is Number line?
Number line is a straight line with numbers placed at equal intervals.
Given that;
Point C is located at -4.
Point D is located at 6.
Now,
Distance between points -4 and 6 is,
6 - (-4) = 6 + 4 = 10
Since, Point P be located so that the directed line segment from C to D will be partitioned in a 2 : 3.
Let partitions are 2x and 3x.
Then,
2x + 3x = 10
5x = 10
x = 2
So, The partitions between point C and D is,
2x = 2 × 2 = 4
3x = 3 × 2 = 6
So, The ratio become = 4 : 6
Thus, Position of point P from C = - 4 + 4 = 0
Position of point P from D = 6 - 6 = 0
So, The position of point P is at 0 on number line.

What is the value of p in the linear equation 24p +12 - 18p = 10 + 2p - 6 ? −4 −2 2 4
Answer:
SO we have to solve this equation:
24p + 12 - 18p = 10 + 2p - 6
First, we will operate what we have in both sides:
24p - 18p + 12 = 10 - 6 + 2p
6p + 12 = 4 + 2p
We substract 2p in both sides and 12 too.
6p + 12 - 2p - 12 = 4 + 2p - 2p - 12
4p = -8
Now, we divide both sides by 4
4p/4 = -8/4
p = -2
The value of p is -2.
The correct option is (B)
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
24p +12 - 18p = 10 + 2p - 6
Now, solving for p
6p + 12= 2p + 4
6p - 2p = 4 -12
4p = -8
p= -8/4
p= -2
Hence, the value of p is -2.

36=4/9d what does d equal
Answer:
d = 81
Step-by-step explanation:
Solve for d:
36 = (4 d)/9
Hint: | Reverse the equality in 36 = (4 d)/9 in order to isolate d to the left hand side.
36 = (4 d)/9 is equivalent to (4 d)/9 = 36:
(4 d)/9 = 36
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of (4 d)/9 = 36 by 9/4:
(9×4 d)/(4×9) = 9/4×36
Hint: | Express 9/4×4/9 as a single fraction.
9/4×4/9 = (9×4)/(4×9):
(9×4)/(4×9) d = 9/4×36
Hint: | Express 9/4×36 as a single fraction.
9/4×36 = (9×36)/4:
(9×4 d)/(4×9) = (9×36)/4
Hint: | Cancel common terms in the numerator and denominator of (9×4 d)/(4×9).
(9×4 d)/(4×9) = (4×9)/(4×9)×d = d:
d = (9×36)/4
Hint: | In (9×36)/4, divide 36 in the numerator by 4 in the denominator.
36/4 = (4×9)/4 = 9:
d = 9×9
Hint: | Multiply 9 and 9 together.
9×9 = 81:
Answer: d = 81
Answer: d=81
Step-by-step explanation:
Given
36=4/9 d
Divide both sides by 4/9 (division property of equality)
d=36 ÷ (4/9)
Turn division of fraction into multiplication of its reciprocal

and m\angle B=(2x-9)^{\circ}∠B=(2x−9)
∘
, then find the value of x.
Answer:
[tex]x=21\textdegree[/tex]
Step-by-step explanation:
So we know that:
[tex]\angle A=3x-30 \text{ and}\\\angle B=2x-9[/tex]
And that the two angles are vertical angles.
Since they are vertical angles, their measurements are equivalent. Thus, to find x, set the equations equal to each other:
[tex]\angle A=\angle B\\(3x-30)=(2x-9)[/tex]
Now, solve for x. Add 30 to both sides. The left side cancels:
[tex](3x-30)+30=(2x-9)+30\\3x=2x+21[/tex]
Now, subtract 2x from both sides. The right cancels:
[tex](3x)-2x=(2x+21)-2x\\x=21[/tex]
Thus, the value of x is 21.
All of the x values or inputs are called what?
Answer:
its called a Domain
Step-by-step explanation:
All of the x-values or inputs are called Domain.
"x-values" is the word used in mathematics and statistics to describe the input values or independent variables in a function or equation.
These x-values stand for a function's inputs, arguments, or the points at which a mathematical connection is being assessed.
The outputs or dependent variables of a function are represented by the appropriate y-values, which are often paired with the associated x-values. The link between the independent and dependent variables can be seen on a graph by plotting the x-values and y-values together as data points.
For example, in the equation y = 2x + 3, "x" represents the x-values or inputs, while "y" represents the corresponding y-values or outputs. By substituting different values for x, you can calculate the corresponding y-values and observe how changes in the x-values affect the relationship described by the equation.
Hence the answer is Domain.

Answer:
maya drives 110 miles in 5 hours. If she continued at the same rate, how long would it take to travel 176 miles?
We use the rule of three
110 miles -------------> 5 hours
176 miles ------------> ???
So (176 miles × 5 hours) /110 miles
We simplify by 《miles》 because it is in the numerator and the denominator
SO (176×5 hours )/110
= 880 hours / 110
= 8 hours
So she drives 176 miles in 8 hours.

Answer:
P = 2 / 25
Step-by-step explanation:
If we assume that the combination of green and pink means, 1 green and 1 pink, then we can say the following:
P = 1 / 25 + 1 / 25
P = 2 / 25
This is because the squares where green and pink intersect only occurs twice.
Hence, the probability is P = 2 / 25.
