Solve forj.
-1/3=j/4-10/3
Answer:
j=12
Step-by-step explanation:
[tex]-\frac{1}{3}=\frac{j}{4}-\frac{10}{3}[/tex] is what we start with. first, do the inverse of -10/3. therefore, we add 10/3 to both sides.
[tex]\frac{9}{3}=\frac{j}{4}[/tex] is what we end up with. then simplify.
[tex]3=\frac{j}{4}[/tex] is what we have after simplifying. next we do the inverse of dividing by 4, so we multiply by 4.
[tex]12=j[/tex] is the final answer. or j=12. hope this helps!

What is the vertex of the graph of f(x) = |x – 13| + 11?
(–11, 13)
(–13, 11)
(11, 13)
(13, 11)
Answer:
(13, 11)
Step-by-step explanation:
I graphed the line and the vertex is at 13, 11
The vertex of the function f(x) = |x - 13| + 11 is (13,11)
How to determine the vertex?The function is given as:
f(x) = |x - 13| + 11
The above function is an absolute value function
An absolute value function is represented as:
f(x) = a|x – h| + k
Where, the vertex is (h,k)
So, we have:
(h,k) = (13,11)
Hence, the vertex of the function f(x) = |x - 13| + 11 is (13,11)

help i need help with ii and iii :(
9514 1404 393
Answer:
i) exponential; values have a common ratio; f(x) = -2·4^x
ii) linear; values have a common difference; f(x) = 4x -3
iii) exponential; values have a common ratio; f(x) = 4·2^x
Step-by-step explanation:
Sequential, or evenly-spaced, input values will result in output values with a common difference if the function is linear. They will result in output values with a common ratio of the function is exponential.
The initial value, or y-intercept, is the value when x=0. The general form of the formulas is ...
linear: f(x) = (common difference)·x + (initial value)
exponential: f(x) = (initial value)·(common ratio)^x
__
i) The f(x) values have a common ratio of -8/-2 = 4, so the relation is exponential. The initial value is f(0) = -2. The equation is ...
f(x) = -2·4^x
__
ii) The f(x) values have a common difference of 1 -(-3) = 4, so the relation is linear. The initial value is f(0) = -3. The equation is ...
f(x) = 4x -3
__
iii) The f(x) values have a common ratio of 8/4 = 2, so the relation is exponential. The initial value is f(0) = 4. The equation is ...
f(x) = 4·2^x

What is the point slope form of a line with a slope of 5 and goes through the
point (1,5)? *
Answer:
y-5=5(x-1)
Step-by-step explanation:
Point slope form is: y-y1=m(x-x1)
y1 here is 5 and x1 is 1, because those are the points in the ordered pair given.
y-5=x-1 would be your base answer, but you need to account for the slope as well, which is m. So, y-5=5(x-1)
Hope this helped! :)

Step-by-step explanation:
The foundation of the house is 13 m x 7 m if the builder increases each dimension by the same amount the area of the foundation will increase to 135 m² find the new dimensions
Answer:
New dimension:
Length = 15m
Width = 9m
Step-by-step explanation:
Length = 13m
Width = 7m
Area of a rectangle = length × width
New dimensions:
Length = (13 + x)m
Width = (7 + x)m
Where,
x = increase in each dimension
Area of a rectangle = length × width
(13 + x) × (7 + x) = 135
91 + 13x + 7x + x² = 135
91 + 20x + x² = 135
x² + 20x = 135 - 91
x² + 20x = 44
x² + 20x - 44 =0
Using factorization method to solve quadratic equation
x² - 2x + 22x - 44 = 0
x(x -2) + 22(x - 2) = 0
(x - 2) (x + 22) = 0
x = 2 , x = -22
The increase can not be a negative value
Therefore, the increase in the dimensions is 2 inches
New dimensions:
Length = (13 + x)m
= (13+2)m
= 15m
Width = (7 + x)m
= (7+2)m
= 9m
What is negative 3/2 divided by 11/6?
Answer: 0.81818181818
Step-by-step explanation:
Answer:
-9/11
Step-by-step explanation:
You have to find the reciprocal of the number you're dividing by. In your case the number you are dividing by is 11/6. Just flip 11/6 to get the reciprocal, and the multiply it by -3/2. 6/11 is the reciprocal of 11/6.
[tex]-\frac{3}{2} * \frac{6}{11} = -\frac{18}{22}[/tex]
Simplify by dividing by 2.
-9/11 is the answer.
HOPE THIS HELPS!!

Answer:
D. add all the y values to get 696 and then add all the x values and get 11.6 divide 696 by 11.6 and you get 60. You get the y-values by multiplying 60 by the x value, so D is the correct answer

What type of angles are these?
Answer:
I believe that the answer is the 5th one (Adjacent angles).
Step-by-step explanation:
Adjacent angles are two angles that share a common side and vertex.
Complementary angles are mostly the same but their degrees add up to 90.
Supplementary angles are similar to complementary angles but add up to 180 degrees.
Vertical angles intersect though each other and are not perpendicular (which perpendicular angles also intersect, but all angles are 90 degrees and they all add up to 360 degrees).
Linear angles are like their name, they are linear. And, they usually intersect like vertical angles. Have a linear relationship between the angles.
The angles shown on the pictures are not any of the answers, except adjacent. They don't add up to 90 degrees, so they are not complementary. They share the same common side and vertex. These facts lead up to one answer which is adjacent. These angles are adjacent.

Answer: x = -6
Step-by-step explanation:
Since 2 angles have to equal 180, you add both of the angles you see and figure out what that answer is
101+91=192
192 - x - x
192 - 6 - 6 = 180
Answer: x=-6
Step-by-step explanation:
They are supplementary angles so both measures = 180. So x+91+x+101=180. 2x+192=180. 2x=-12. X=-6

How many different committees can be formed from 10 teachers and 37 students of the committee consist of three teachers and two students? how many ways can the committee of five members be selected?
Answer:
79,920 different ways
Step-by-step explanation:
Combination has to do with selection:
If we are to select 3 teachers from a pool of 10 teachers to form a committee, this can be done in 10C3 number of ways.
10C3 = 10!/(10-3)!3!
10C3 = 10!/7!3!
10C3 = 10*9*8*7!/7!3!
10C3 = 10*9*8/3*2
10C3 = 720/6
10C3 = 120 ways
Similarly, selecting five 2 students from a pool of 37 students to form a committee, this can be done in 37C2 difference ways;
37C2 = 37!/(37-2)!2!
37C2 = 37!/35!2!
37C2 = 37*36*35!/35!*2
37C2 = 37*36/2
37C2 = 37 * 18
37C2 = 666 ways
Hence the total number of ways that the 5 committees can be selected is expressed as 10C3 * 37C3 = 120 * 666
120 * 666 = 79,920 ways

Peter is practicing how to apply the distributive property. In which example(s) did Peter NOT correctly apply the distributive property?
12(x-2)=12x-24,
3p-6=1/2(6p-12,
7(b+1)=7b+1
,-(w-2)=w+2, 8m+4=2(4m-2)
i need an answer by 12:25 TODAY
Answer:
-(w-2)=w+2, 8m+4=2(4m-2) Is NOT correct
Step-by-step explanation:
because..... when we multiply -(w-2) we get -w+2. Peter forgot to multiply the negative sign. 8m+4=2(4m-2) is not correct because 2 x 4m is 8m but 2 x 2 is 4 NOT 2 x -2. 2 x -2 is -4.

The amount a hardware store pays for buying nylon rope is represented by the equation y 5 0.12x, where y is the price it pays for x feet of rope. The amount the hardware store charges when selling the rope is represented by the graph.
The profit the store makes on the rope can be found by subtracting the amount it charges for the rope from the price it pays for the rope. If the store sells 80 feet of rope, how much profit does it make on that rope?
(Look at the link)
Please answer I really need help.
Answer:
Ayo its ( $6.40 )
Step-by-step explanation:
I did it for my do now once.
The profit would be $6.4 if the store sells 80 feet of rope the answer would be $6.4.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The amount a hardware store pays for buying nylon rope is represented by the equation
y = 0.12x, where y is the price it pays for x feet of rope.
Plug x = 80 feet
y = 0.12(80)
y = $9.6
The equation for the graph:
y = 0.20x
Plug x = 80 feet
y = $16
The profit = 16 - 9.6 = $6.4
Thus, the profit would be $6.4 if the store sells 80 feet of rope the answer would be $6.4.
