Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (-4, 0)

Point (-3, -1)

Step 2: Find slope m

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)

Hope this helped! :)

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

Step-by-step explanation:

Answer:

-5 is the only one. -2 would be if the circle on the line was solid, but it's an open circle so the number it's on isn't included.

I'm On that test ATM and was wondering if you could give me the aswners to numbers 7 8 9

But the awnser to that question is -5

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:

-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.

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: 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

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:

  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

n(x) will give output for any number except 0.

An equation consists of two sides, the left-hand side and the right-hand side, which are separated by an equals sign (=). The left-hand side and the right-hand side each contain one or more variables, which are quantities that can vary or be assigned different values.

Given

n(x)=2/x

From the given option, 3 and5  will satisfy the equation.

n(x)=2/3 for the value of x=3

n(x)=2/5 for the value of  x=5

For the value of x=0

O will not satisfy.

n(x)=2/0=not defined

Hence, n(x) will give output for any number except 0.

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.

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:

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!
