Answery

y =−4x+3

Step-by-step explanation:

The slope-intercept form of a linear equation is:

y =m x+b

Where  m is the slope and b

is the y-intercept value.

Substituting the values from the problem gives:

Answer: the original slope is 3/2

The perpendicular slope is -2/3

Slope is rise/run

Step-by-step explanation: For the original slope get  

Find coordinates where the graphed line crosses the grid lines at the intersections. Here, (0,-2) and (2,1) Count the number of squares vertically. That is the rise. It is the difference in y-values. It is the numerator of the fraction. Then count the squares horizontally to get the run. That is the denominator of the fraction.

It is possible to use the expression [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex] to calculate the slope.

[tex]\frac{1-(-2)}{2-0} = 3/2[/tex]

To find the perpendicular slope, reverse the sign and use the reciprocal of the original fraction.

The reciprocal of 3/2 is 2/3. The opposite sign is negative. -2/3

im sorry if this is wrong but im 99% sure this is right

i only put things in parenthesis to make things work better in my brain

Answer:

m = -2

Step-by-step explanation:

4 + 4{m + 1} = 0           {Subtract 4 form both sides}

   4{m + 1} = -4

   4m + 4 = -4             {Subtract 4 form both sides}  

         4m = -4 - 4

        4m  = -8             {Divide both sides by 4}

        m = -8/4

m = -2

The number of weeks that they cat treats will train out is 27 weeks.

From the information given, the total grams will be:

= 200 + (2.5 × 1000)

= 200 + 2500

= 2700 grams.

Then he uses about 100 grams of cat treats every week, the number of weeks will be:

= 2700 / 100

= 27

There'll be 27 weeks.

You aren't supposed to add 3k

Step-by-step explanation:

3k is a positve number. So instead of adding you have to subtract to be able to move on. Correct way shown below. Once you get this step wrong your answer will also be wrong. At the end you also need to divide

19-2k= 3k-1

  -3k  -3k

19-5k= -1

-19      -19

 -5k= -20

-5/-5= -20/-5

    k=4

[tex]\frac{x}{3}+5=x-1[/tex]

Whenever there's a denominator. Multiply all whole equation with the denominator. For example, the denominator here in the equation is 3. So we multiply the whole equation by 3.

[tex]\frac{x}{3}(3)+5(3)=x(3)-1(3)\\x+15=3x-3[/tex]

Moving the x to the same term which goes for the same as the constant for easier in solving.

[tex]15+3=3x-x[/tex]

Moving to the another side, changing the sign/operator to opposite (From plus to minus, from multiply to divide.)

[tex]18=2x\\2x=18\\[/tex]

Move 2 to another side, aka to divide 18.

[tex]x=\frac{18}{2}\\x=9[/tex]

Therefore, the answer is x = 9.

Answer:

The value of x is 27

Step-by-step explanation:

The sum of the exterior angles of the n-side polygon is 360°

Let us use this rule to solve the question

∵ The given polygon has 4 sides

∴ It has 4 exterior angles, one on each vertex

→ By using the rule above

∴ The sum of the 4 angles is 360°

∵ The exterior angles are (2x + 40)°, (4x)°, (x + 50)°, and (3x)°

→ Add them, then equate the sum by 360

∴ (2x + 40) + (4x) + (x + 50) + 3x = 360

→ Add the like terms in the left side

∵ (2x + 4x + x + 3x) + (40 + 50) = 360

∴ 10x + 90 = 360

→ Subtract 90 from both sides

∵ 10x + 90 - 90 = 360 - 90

∴ 10x = 270

→ Divide both sides by 10

∴ x = 27

∴ The value of x is 27

The largest value of x that would make buying the individual card less expensive than buying the package is 57.

The total cost of buying the individual thankyou cards is the product of the cost of buying one card and the number of cards bought.

Total cost of buying the individual thankyou cards = cost per card x number of cards bought

$0.15 × x = $01.5x

The inequality equation that would be used to represent this question is

(total cost of individual thankyou cards) > cost of the package

$0.15x > $8.50

In order to determine the value of x, divide both sides of the equation by 0.15

x > (8.50 / 0.15)

x > 56.67

x > 57 to the nearest whole number

The value of m in the inequality 28 > 4+1.5m is 16

A relationship between two expressions or values that are not equal to each other is called 'inequality.

To solve for m, we need to isolate it on one side of the inequality.

We can start by subtracting 4 from both sides:

28 - 4 > 1.5m

Simplifying:

24 > 1.5m

Next, we can divide both sides by 1.5:

16 > m

So Kate can travel at most 16 miles in the cab if she wants to spend no more than $28 on cab fare.

Therefore, the value of m in the inequality 28 > 4+1.5m is 16

Answer:

0.44x10^3

Step-by-step explanation:

The number has to be from 1 to 10, not below 1, like 0.44 does.

Step-by-step explanation:

= 40 + [ 3 { 18 ÷ ( 9 - 3 ) - 11 - 9 } + 4 ]

= 40 + [ 3 { 18 ÷ 6 - 11 - 9 } + 4

= 40 + [ 3 { 3 - 20 } + 4

= 40 + [ 3 {- 17 } + 4

Answer:

Option D: the x-intercept represents the minimum amount of photographs he must sell to pay for his photography lab.

Step-by-step explanation:

We are told that his monthly profit is given by the relation;

P = 32.5x - 845

Where x is number of pictures he needs.

We want to find what the x - intercept represents.

x intercept means that the y-value at that point is zero.

Thus, x-intercept means the profit is 0.

If profit is zero, it means his cost of operating his photography lab each month is equal to the amount of photographs he is able to sell.

Thus, it means that the x-intercept represents the minimum amount of photographs he must sell to pay for his photography lab monthly.
