Answer:
y = 3.2
Step-by-step explanation:
Consider this ratio: y/x = 24/15. This will be used later to isolate the y variable.
Now, replace y/x with 24/15 respectively and y/2 respectively. Solve for Y by simplifying and isolating the y variable.
24/15 = y/2
3.2 = y
1. Rotate ABC 180° about the origin making
DEF.
List all congruent sides and angles:
Answer:
∠ABC≅∠DEF ∠BCA≅∠EFD ∠CAB≅∠FDE AB≅DE, BC≅EF, CA≅FDStep-by-step explanation:
To rotate point A 180° about the origin (point O) we draw a line from that point (A) throu the origin, measure the distance from the point A to the origin, and then measure the same distance on the other side of the origin to get rotated point. Mark it. The angle at the rotated point will be congruent to ∠A
The same goes for points B and C
Angles at pair of given and rotated point are congruent.
Sides of triangle are congruent if they lay between two congruent angles.

Step 1:
( 9 - 3 ) + 20 ÷ 4 Equation
Step 2:
6 + 20 ÷ 4 Subtract
Step 3:
6 + 5 Divide
Answer:
11 Add
PEMDAS:
1. Parenthesis
2. Exponents
3. Multiplication
4. Division
5. Addition
6. Subtraction
Hope This Helps :)
Answer:
The answer is 11.
Step-by-step explanation:
Use PEMDAS
P - Parenthesis
E - Exponents
M - Mulitiplication
D - Divide
A - Add
S - Subtract
So, with that you learn that you solve whatever is in the parenthesis first.
(9 - 3) = 6
Now, divide 20 by 4 which equals 5.
So now the problem is now 6 + 5 which equals 11.
The answer is 11.

Step-by-step explanation:
Describe in words the translation of X represented by the translation rule T ...?
The vector notation <4, -5> is the same as writing [tex](x,y) \to (x+4, y-5)[/tex] which in my opinion is more descriptive in saying "4 units to the right, 5 units down"
We shift 4 units to the right because of the x+4. Whatever x is, add 4 to it getting x+4. So for instance x = 10 leads to x+4 = 10+4 = 14.
The y-5 is why we shift 5 units down. Eg: y = 37 leads to y-5 = 37-5 = 32.
Is this pattern a net for the three-dimensional figure?
Yes
No
Answer:
The answer is yes. Is yes
What is the equation in slope – intercept form? 7x + 2y = 14
Answer:
y = - [tex]\frac{7}{2}[/tex] x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
7x + 2y = 14 ( subtract 7x from both sides )
2y = - 7x + 14 ( divide all 3 terms by 2 )
y = - [tex]\frac{7}{2}[/tex] x + 7 ← in slope- intercept form

To make 112 dozen muffins, a recipe uses 312 cups of flour.
How many cups of flour are needed for every dozen muffins made?
Enter your answer in the box as a mixed number in simplest form.
Answer:
Interesting question.
112/12 = 28/3
so 3/28 * 112 = 12
so we multiply 3/28 * 312
936/28
Simplifying we get 33 3/7
[tex]33 \frac{3}{7}[/tex] is the answer.
This is a mixed number with 2 as the whole part and 11/14 as the fractional part.
You may need to drop the ampersand sign and simply say 2 11/14
==============================================
Work Shown:
112 dozen muffins = 312 cups of flour
112/112 dozen muffins = 312/112 cups of flour
1 dozen muffins = 312/112 cups of flour
1 dozen muffins = (39*8)/(14*8) cups of flour
1 dozen muffins = 39/14 cups of flour
1 dozen muffins = (28+11)/14 cups of flour
1 dozen muffins = (28/14+11/14) cups of flour
1 dozen muffins = (2+11/14) cups of flour
1 dozen muffins = 2 & 11/14 cups of flour
Evaluate the following when $a = 3$, $b = \frac14$, and $c = 5$: \[ \frac{b^{-1}}{ca^{-1} - ac^{-1}}. \] Thank you so much!
[tex]\dfrac{b^{-1}}{ca^{-1}-ac^{-1}}=\dfrac{\frac1b}{\frac ca-\frac ac}[/tex]
Multiply the numerator and denominator by [tex]ac[/tex]:
[tex]\dfrac{\frac1b}{\frac ca-\frac ac}\cdot\dfrac{ac}{ac}=\dfrac{\frac{ac}b}{c-a}[/tex]
Since [tex]b=\frac14[/tex], we have [tex]b^{-1}=\frac1b=4[/tex]. So substituting the values of a, b, and c gives us
[tex]\dfrac{\frac{ac}b}{c-a}=\dfrac{3\cdot5\cdot4}{5-3}=\dfrac{60}2=\boxed{30}[/tex]
Answer:
15/4
