Use the vertical line test to determine whether the relation is a function​

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.

I hope I helped! ✨

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!

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)

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)

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.

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.

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: 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.

Step-by-step explanation:

Simplify the following:

(1 + 1/9) (4 + 1/2) + 3 + 1/5 - 1/3

Put 1 + 1/9 over the common denominator 9. 1 + 1/9 = 9/9 + 1/9:

9/9 + 1/9 (4 + 1/2) + 3 + 1/5 - 1/3

9/9 + 1/9 = (9 + 1)/9:

(9 + 1)/9 (4 + 1/2) + 3 + 1/5 - 1/3

9 + 1 = 10:

10/9 (4 + 1/2) + 3 + 1/5 - 1/3

Put 4 + 1/2 over the common denominator 2. 4 + 1/2 = (2×4)/2 + 1/2:

10/9 (2×4)/2 + 1/2 + 3 + 1/5 - 1/3

2×4 = 8:

10/9 (8/2 + 1/2) + 3 + 1/5 - 1/3

8/2 + 1/2 = (8 + 1)/2:

10/9 (8 + 1)/2 + 3 + 1/5 - 1/3

8 + 1 = 9:

10/9×9/2 + 3 + 1/5 - 1/3

10/9×9/2 = (10×9)/(9×2):

(10×9)/(9×2) + 3 + 1/5 - 1/3

(10×9)/(9×2) = 9/9×10/2 = 10/2:

10/2 + 3 + 1/5 - 1/3

The gcd of 10 and 2 is 2, so 10/2 = (2×5)/(2×1) = 2/2×5 = 5:

5 + 3 + 1/5 - 1/3

Put 5 + 3 + 1/5 - 1/3 over the common denominator 15. 5 + 3 + 1/5 - 1/3 = (15×5)/15 + (15×3)/15 + 3/15 - 5/15:

(15×5)/15 + (15×3)/15 + 3/15 - 5/15

15×5 = 75:

75/15 + (15×3)/15 + 3/15 - 5/15

15×3 = 45:

75/15 + 45/15 + 3/15 - 5/15

75/15 + 45/15 + 3/15 - 5/15 = (75 + 45 + 3 - 5)/15:

Answer:

Y= -5/3x +1. And y= -3/5x -5

Step-by-step explanation:

For both equations subtract x term first. For first equation, you subtract 5x. Second equation subtract 3x. Next divide by coefficients of y. For first equation it is 3, for the second it is 5.

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

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

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)

Answer: y+1=-5(x-2)

Step-by-step explanation:

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
