Give an example with an expression showing the associative property of multiplication
Answer:
Use the associative property of multiplication to rewrite (5 x 4) x 3 In order to rewrite the expression, take the parenthesis off of the first two factors and put them around the last two factors. Answer: 5 x (4 x 3) Example: Use the associative property of multiplication to rewrite (6 x 2) x 7
Graph the following system of equation
y= 3x + 11
y= -4x + 4
Answer:
Step-by-step explanation:
Answer:
These equations describe two lines that intersect at the point (-1, 8), one of them with a slope of 3, the other with a slope of -4.
Step-by-step explanation:
We can find the point where these two lines intersect by taking one of the equations, solving it for x, and substituting it into the other equation.
[tex]y = -4x + 4\\-4x = y - 4\\4x = 4 - y\\x = 1 - \frac{y}{4} \\\\y = 3x + 11\\y = 3(1 - \frac{y}{4}) + 11\\y = 3 - \frac{3y}{4} + 11\\y + \frac{3y}{4} = 3 + 11\\\frac{4y}{4} + \frac{3y}{4} = 14\\\frac{7y}{4} = 14\\y = \frac{4}{7} * 14\\y = 4 * \frac{14}{7}\\y = 4 * 2\\y = 8[/tex]
Now we can plug that into our first equation to find x
[tex]x = 1 - \frac{y}[4}\\x = 1 - \frac{8}[4}\\\\x = 1 - 2\\x = -1[/tex]
So these lines intersect at the point (-1, 8), one of them with a slope of 3, the other with a slope of -4

10.) Dilation with the center at the origin and a scale factor of 1/3.
Step-by-step explanation:
PAGE 1
3.) d
b/c the rule for x-axis is (x,y) --> (x, -y)
One of the points is (1, 1) ==> (1, -1)
4.) The rule for y-axis is (x, y) --> (-x, y)
A(-5, 3) --> A'(5, 3)
B(2, 6) --> B'(-2, 6)
C(-1, -7) --> C'(1, -7)
PAGE 2
5.) The rule for x-axis is (x,y) --> (x, -y)
A(-5, 3) ---> A'(-5, -3)
B(2, 6) ---> B'(2, -6)
C(-1, -7) ---> C'(-1, 7)
6.) The rule for 90 degrees clockwise is (x, y) --> (y, -x)
B(3, 4) ---> B'(4, -3)
PAGE 3
1.) On the transitions right is positive and left is negative
So 2 units to the right = +2
And 9 units down = - 9
So (x, y) --> (x + 2, y - 9)
2.) A is wrong b/c that translation is (x, y) ---> (x + 3, y -3)
B is wrong b/c the translation is (x, y) ---> (x + 3, y + 3)
C is wrong b/c the translation is (x, y) ---> (x - 3, y + 3)
D is correct b/c the translation is (x, y) --->(x -3 , y -3)
A(6, 6) --> A'(3, 3) B(7, 4) --> B'(4, 1) C(4, 4) --> C'(1, 1)
PAGE 4
7.) The rule for 90 degrees rotation counterclockwise is (x, y) --> (-y, x)
The correct graph would show A(-3, 3) ----> (-3, -3)
The only graph that shows this is Graph C
8.) The rule for 180 degrees rotation is (x, y) ----> (-x, -y)
The correct graph would show A(-3, 3) ----> A'(3, -3)
Graph B is the only one that ALL the angles follow this rule
PAGE 5
9.) It is Dilation with the center at the origin and a scale factor of 2.
B/c --> A(3, 3) ---> A'(6, 6) B(2, 0) ---> B'(4, 0) C(5, 2) ---> C'(10, 4)
(3*2= 6, 3*2=6) (2*2= 4, 0*2= 0) (5*2= 10, 2*2= 4)
10.) It is Dilation with the center at the origin and a scale factor of 1/3
B/c ---> A(-3, 6) --> A'(-1, 2) B(12, 3) ----> B'(4, 1) C(-6, -6) ---> C'(-2, -2)
(-3*1/3= -1, 6*1/3= 2) (12*1/3= 4, 3*1/3= 1) (-6*1/3= -2, -6*1/3= -2)

What is the value of the expression 6 3/4 ( -11.5)?
Answer:
I'm assuming your problem looks like this: 4+5*6-3 =? To solve this problem you need to use the order of operations. PEMDAS which stands for Parentheses, exponents, multiply and divide, and lastly add and subtract. You must multiply and divide before you add and subtract so you must do 5*6 first. You now get 4+30-3. Now all you have left is addition and subtraction so you now just go from right to left and do one at a time. So 4+30 = 34 , 34-3=31. Therefore your answer should be 31. Hope that helped!

Kate's math homework had a set of equations and a one-word problem. She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total, how many equations did she solve
Answer:
15 equations
Step-by-step explanation:
Let
Number of equations in the homework = x
There is only a one-word problem
y = amount of time used to solve the word problem
She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total,
Total = 3x + y
52 = 3x + 7
Subtract 7 from both sides
52 - 7 = 3x + 7 - 7
45 = 3x
Divide both sides by 3
x = 45 / 3
= 15
x = 15 equations
Therefore, she solved 15 equations

Verizon offers a cell phone plan where customers buy a cell phone for $300 and pay a monthly fee of $40. T- Mobile offers a cell phone plan where customers buy a cell phone for $200 and a monthly rent of $60. Write the equation needed to find the number of months a customer would have to own a cell phone in order for the two cell phone companies to be equal. PLEASE ANSWER QUICKLY. need help!!!
Answer:
A customer would have to own a cell phone for 5 months in order for the two companies to be equal.
Step-by-step explanation:
Given that:
Cost of cell phone at Verizon = $300
Monthly fee = $40
Let,
x be the number of months
V(x) = 40x + 300
Cost of cell phone at T-mobile = $200
Monthly fee = $60
T(x) = 60x + 200
For equal amount of money,
V(x) = T(x)
40x+300=60x+200
300-200=60x-40x
100=20x
20x=100
Dividing both sides by 20
[tex]\frac{20x}{20}=\frac{100}{20}\\x=5[/tex]
Hence,
A customer would have to own a cell phone for 5 months in order for the two companies to be equal.
One tomato plant is 12 inches tall in a grows 1.5 inches per week another tomato is 6 inches tall and grows 2 inches per week after how many weeks will the plants the same height?
Just need the equation that’s it I don’t know how to write it...
Find the measure of <1
Consider the triangle (in which angle4 is present)
by angle sum property,
20 + 40 + angle4 = 180
60 + angle4 = 180
angle4 = 180 - 60
angle4 = 120
Also,
angle2 = 120 (vertically opposite angles)
angle1 + angle2 = 180 (linear pair)
angle1 + 120 = 180
angle1 = 180 - 120
angle1 = 60

In the figure below, ray KM is the angle bisector of ZLKJ. If MZLKJ = 82",
what is MZMKJ?
Answer:
41º
Step-by-step explanation:
An angle bisector splits an angle in half. So angle LKM+angle MKJ=angle LKJ. We know angle LKJ=82º, so angle LKM=angle MKJ=82º/2=41º.

Find the value of x in the diagram below.
Answer:
x = 31
Step-by-step explanation:
The 2 sides are congruent, meaning the 2 angles are equal so:
47 = x + 16
subtract 16 from both sides
31 = x
HELP PLEASE ITS Which point would not be a solution to the system of linear inequalities shown below? y -3x+7!
(5,−5)(10,−8)(5,−6)(−10,−7)
Answer:
(-10,-7)
Step-by-step explanation:
Lets start with the equation y>-3x+7
Which of these are solutions?
(5,-5) - yes
(10,-8) - yes
(5,-6) - yes
(-10,-7) - no
Now lets do the equation y<4/5x-2
Which of these are solutions?
(5,-5) - yes
(10,-8) - yes
(5,-6) - yes
(-10,-7) - no
So, the point (-10,-7) is not a solution to the system of equations.

Harper is making pudding cups for a big celebration. She made 5 pounds of pudding, but she needs to separate the pudding into individual 4-ounce cups. How many total individual pudding cups can Harper make?
Given :
Total amount of pudding made, T = 5 pounds.
Size of each cup, s = 4 ounces.
To Find :
How many total individual pudding cups can Harper make.
Solution :
Let, n number of pudding cups can filled with 5 pounds pudding.
We know, 1 pound = 16 ounces.
So, 5 pounds = 16×5 = 80 ounces.
Now,
[tex]n = \dfrac{80}{s}\\\\n = \dfrac{80}{4}\\\\n = 20 \ cups[/tex]
Therefore, 20 cups can be filled with 5 pounds of pudding.
