Answer:
4-3y and 2−4x
Step-by-step explanation:
Use the distributive property to multiply 1/3 by 12−9y.
1/3⋅12+1/3 (−9)y
Multiply 1/3 and 12 to get 12/3.
12/3+1/3 (−9)y
Divide 12 by 3 to get 4.
4+1/3 (−9)y
Multiply 1/3 and −9 to get (−9)/3.
4+(−9)/3 y
Divide −9 by 3 to get −3.
4−3y
Use the distributive property to multiply 1/4 by −16x+8.
1/4 (−16)x+1/4⋅8
Multiply 1/4 and −16 to get (−16)/4.
(−16)/4 x+1/4⋅8
Divide −16 by 4 to get −4.
−4x+1/4⋅8
Multiply 1/4 and 8 to get 8/4.
−4x+8/4
Divide 8 by 4 to get 2.
−4x+2
The expressions 1/3(12-9y) and 1/4(-16x+8) are simplified by distributing the fractions over each term inside the parentheses, resulting in the simplified forms 4 - 3y and -4x + 2, respectively.
Explanation:To solve the two separate algebraic expressions given, we'll perform operations step by step.
Solution for 1/3(12-9y):
Solution for 1/4(-16x+8):
Note that these are not equations with equals signs, so we cannot 'solve for y or x' in the traditional sense; we merely simplified the expressions.

Which of the values will NOT make 3x < 45 true?
12
11
16
-8 im being timed
Answer:
16
Step-by-step explanation:
3 times 16 is 48
hope this helps :)
Final answer:
The value that will not make the inequality 3x < 45 true is 16, as any value greater than or equal to 15 does not satisfy the inequality.
Explanation:
To determine which values will not make the inequality 3x < 45 true, we first solve the inequality for x by dividing both sides by 3.
Dividing 45 by 3 gives us:
45 / 3 = 15
So the inequality becomes:
< 15
Any value for x that is 15 or greater will not satisfy the inequality. Looking at the provided options (12, 11, 16, -8), the number 16 is the only value that is greater than 15, and hence, will not make the inequality true.
What is the measure of the missing angle
The sum of the angles of any quadrilateral is 360 degrees. This means that you can make a formula like the one bellow and solve for x:
72 + 107 + x + 91 = 360
270 + x = 360
(270 - 270) + x = 360 - 270
x = 90
Hope this helped!
~Just a girl in love with Shawn Mendes
Answer:
x = 90°
Step-by-step explanation:
Angles in a quadrilateral add up to 360°
We are given the following angles : 107°, 72° and 91°
Wee need to find x so,
x + 107° + 72° + 91° = 360°
( Simplify )
x + 270° = 360°
( Minus 270° from both sides to isolate x )
x = 90°
The output with the y being -4
For this case we have a function of the form [tex]y = f (x)[/tex], where [tex]f (x) = - 4x[/tex]. We must find the values of "and" according to the following function:[tex]y = -4x[/tex]
So:
[tex]f (-6) = - 4 (-6) = 24\\f (-2) = - 4 (-2) = 8\\f (3) = - 4 (3) = - 12[/tex]
Thus, the values are:

A. 7x^3 +2x -6
B. 4x^2 -x
C. 7x^2 -2x-6
D. 7x^2- 8x-6
Answer:
Let's simplify step-by-step.
7x^2−3x+5x−6
=7x^2+−3x+5x+−6
Combine Like Terms:
=7x^2+−3x+5x+−6
=(7x^2+2x+−6 )
Answer:
=7x^2+2x−6
Final answer:
The sum of (7x² - 3x) and (5x - 6) is found by combining like terms, resulting in 7x² + 2x - 6, which is option C.
Explanation:
To solve the algebraic addition (7x²-3x) + (5x-6), you need to combine like terms.
First, identify and group like terms from both expressions. Like terms are those that have the same variable raised to the same power.
Combine the coefficients (numerical values) for each group of like terms.
Now, let's go through each step:
For the x2 terms: 7x2 (from the first polynomial) has no like term in the second polynomial, so it remains as is.
For the x terms: -3x (from the first polynomial) and +5x (from the second polynomial) combine to give 2x.
Lastly, the constant terms: -6 (from the second polynomial) also has no like term in the first polynomial, so it remains as is.
By combining these, the result is 7x² + 2x - 6, which corresponds to option C.
12(x-2)+3x=1/2(x+6)+2

Leonardo put a $600 ring on layaway by making a 10% down payment and agreeing to pay $65 a week. How many weeks will it take your nardo to pay off the ring?
Answer: 9 weeks
Step-by-step explanation:
Final answer:
Leonardo will take 9 weeks to fully pay off the $600 ring after making a 10% down payment and weekly payments of $65.
Explanation:
The question is asking how many weeks it will take Leonardo to pay off a ring valued at $600 with a 10% down payment and subsequent weekly payments of $65.
First, calculate the down payment Leonardo makes: 10% of $600 equals $60. Subtract the down payment from the original price to find out the remaining amount Leonardo has to pay, which is $600 - $60 = $540.
Next, divide the remaining amount by the weekly payment: $540 divided by $65 per week equals approximately 8.31, which rounds up to 9 weeks since you can't make a fraction of a payment.
Therefore, it will take Leonardo 9 full weeks to pay off the ring.

The IPhone 7 costs about $220 for Apple to make, but they cost about $700 in stores. What is the markup percentage of the IPhone 7? (Round to the nearest
Answer:
The markup percentage of the IPhone 7 is $218.18%.
Step-by-step explanation:
The IPhone 7 costs for Apple to make = $220
The cost in stores = $700
The difference between costing price and selling price = 700 -220 = $480
The markup percentage of the IPhone 7 = [tex]\frac{480}{220}[/tex] × 100
= $218.18
The markup percentage of the IPhone 7 is $218.18%.
The markup percentage of an iPhone 7 is calculated by finding the difference between the selling and cost price, dividing this by the cost price and then multiplying by 100. According to these steps, the markup percentage of the iPhone 7 is approximately 218%.
Explanation:The markup percentage indicates how much an item's price has increased from its original cost to make. It is calculated by finding the difference between the selling price and the cost to make, then dividing that by the cost to make, and then multiplying it by 100 to get the percentage.
To calculate the markup percentage of the iPhone 7:
Determine the difference between the selling price and the cost price. In this case, $700 (selling price) - $220 (cost price) = $480. Now divide the difference by the cost to make. $480 / $220 = 2.18. Finally, multiply by 100 to get the percentage. 2.18 * 100 = 218% (rounded to the nearest whole number).
Therefore, the markup percentage of the iPhone 7 is 218%.

what do you mean 2<_ 10?
If x<_10,
a) 1,2,5,10
b) 4
c) 6
Answer:
see explanation
Step-by-step explanation:
Given x ∈ { 2, 3, 4, 5, 6, 7, 8, 9, 10 }
Factors of 10 are 1, 2, 5, 10, thus
P = { 2, 5, 10 } ← 1 is not a member of the universal set
and the number of elements in P , that is n(P) = 3
The complement of P is the elements not in P but in the universal set
P' = { 3, 4, 6,7,8,9 }
Which matrix is the product of a 3 × 3 identity matrix and the scalar 3?
Answer:
[tex]\left[\begin{array}{ccc}3&0&0\\0&3&0\\0&0&3\end{array}\right][/tex]
Step-by-step explanation:
In order to find out the resulting matrix, we will have to multiply the identity matric and the scalar 3:
The 3x3 identity matrix is:
[tex]\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right][/tex]
Multiplying with scalar 3:
[tex]3\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right][/tex]
The scalar will be multiplied by each element of the matrix.
Multiplying zeros with scalar 3 will give us zero. So the resulting matrix will be:
[tex]\left[\begin{array}{ccc}3*1&0&0\\0&3*1&0\\0&0&3*1\end{array}\right] = \left[\begin{array}{ccc}3&0&0\\0&3&0\\0&0&3\end{array}\right][/tex]
So the resultant matrix will be a scalar matrix with 3 at diagonal positions..

P/3 + Q/3 =0
Answer:
{Q = -(3 P)/2, Q = -6 P}
Step-by
-step explanation:
Find the graph of the inequality y>-1/6x+1
what we do is, we simply draw the graph for its EQUALITY counterpart, namely [tex]\bf y=-\cfrac{1}{6}x+1[/tex].
then we check the regions on both sides of the graph, in this case we can check say the point (0,0) for simplicity, and
[tex]\bf y>-\cfrac{1}{6}x+1\qquad (0,0)~~ \begin{cases} x=0\\ y=0 \end{cases}\implies 0>-\cfrac{1}{6}(0)+1\implies 0>1[/tex]
now, is 0 > 1? is 0 really greater than 1? nope, is smaller, thus the area where the point (0, 0) is at is the false region, so that's the area we do NOT shade, thus the other region must be the true region and that's the one we shade.
the ">" sign means, that "y" is greater than, NOT equals to but greater, thus the values at the borderline are not included, and thus is a dashed line.
