Answer:

y = -5x -12

Step-by-step explanation:

-5x - y = 12

=> -(5x + y) = 12

=> 5x + y = -12

=> y = -5x -12

2 to the power of 4 = 2 x 2 x 2 x 2 = 16

The answer is 16

Answer:

Slope = -5/3

Step-by-step explanation:

Parallel lines have the same slope, so the slope will be -5/3.

Hope this helps!!

Answer:

-5/3x

Step-by-step explanation:

its the same slope

Answer:

-2x

Step-by-step explanation:

Graph

y > −2x + 3

Use the slope-intercept form to find the slope and y-intercept.

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

y = mx + b

Find the values of m and b using the form y = mx + b. m = −2

b = 3

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope: −2

intercept: (0, 3)

Graph a dashed line, then shade the area above the boundary line since y is greater than

−2x + 3.

y > −2x + 3

Answer:

Step-by-step explanation:

The question is in two parts

For the first part;

Mark up price = 2500

Selling price = Rs 2350

To get the discount rate we will use the expression

Discount = MP-SP/MP× 100

Discount = 2500-2350/2500 × 100

Discount =150/2500 × 100

Discount percent = 150/25

discount percent = 6%

For the second part;

Cost of TV = Rs 33660 (including tax)

Sales tax = 10%

Increment = 10% of 33660

Increment = 0.1×33660

Increment = Rs 3366

Basic price = sales price (including tax)-increment

Basic price = 33660-3366

Basic price = Rs 30,294

k=13

Step-by-step explanation:

180 =(4k-7) + (3k+6) +90

180= 7k+89

-89 -89

91= 7k

÷7 ÷7

k=13

The answer is the third graph or c

Step-by-step explanation:

I just did the test and the other guy is correct to.

Answer:

If you are on edg 2021 then it is the graph with the line going down from 0 to the bottom left square of the graph

Step-by-step explanation:

So it is the first graph.

Answer:

to examine the ratio y/x (instead of x/y). If the x and y coordinates form proportional relationships, then there is some non-changing number (a constant) that when multiplied times x will create y. In this example, that number is 3 (y = 3x), and is called the constant of proportionality.

Step-by-step explanation:

Answer:

In a graph the line must pass through the origin and it has to be a straight line,

In an table the y over x has to be the same for each one

Answer:

144

Step-by-step explanation:

[tex] 100 \div 5 \times 4 + 4^3 = [/tex]

[tex]= 20 \times 4 + 4 \times 4 \times 4[/tex]

[tex] = 80 + 64 [/tex]

[tex] = 144 [/tex]

Answer:

184 would be the correct answer but in the actual question it is 4 by the power of 3 so the answer would be 144

Step-by-step explanation:

100 ÷ 5 = 20 × (4+[tex]4^{3}[/tex]) = 144

Answer:

There are 16 multiple choices and 6 short answers.

Step-by-step explanation:

Let the number of multiple choice questions be x and the number of short answer questions be y.

x + y = 22 (total number of questions)

4x + 6y = 100 (total number of points)

x = 22 - y

4(22 - y) + 6y = 100

88 - 4y + 6y = 100

2y = 100 - 88

y = 6

x + 6 = 22

x = 16

Hence, there are 16 multiple choices and 6 short answers.

Hope this helped!

Given :

Miranda goes to the store she plans to spend $7dollar sign, and each time Savannah goes to the store she plans to spend $9 sign a few weeks from now.

Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store.

To Find :

Least possible number of times that Miranda has been to the store.

Solution :

It is common to see that :

7 dollar/visit ×9 visits = $63

9 dollar/visit ×7 visits = $63

Therefore, minimum number of times Miranda has been to the store is 9.

Hence, this is the required solution.

Answer: 9 times

I just answered the question

Answer:

2x + y = -3 standard form

Answer:

4y = 36-x

Step-by-step explanation:

A linear function is in the form

y = mx + b

for g(0) = 7 ;

x = 0 and y = 9

So ;

9= 0(x) + b

b = 9

For g(8) = 7

x = 8 and y = 7

7 = 8m + 9

7-9 = 8m

8m = -2

m = -2/8 = -1/4

So the equation is;

y = -1/4x + 9

Multiply through by 4

4y = -x + 36

Answer: Oregon

Step-by-step explanation:

For New Jersey:

Number of house of Representatives members = 80

Number of Democrats = 32

Fraction = 32/80 = 2/5

For Oregon:

Number of house of Representatives members = 60

Number of Democrats = 25

Fraction = 25/60 = 5/12

The state that has a greater fraction of Democrats in its House of Representatives is Oregon. This is because 5/12 is greater than 2/5.

[tex]17 \sqrt{2} [/tex]

One of the angle of the triangle is 90 degrees which means it is a right angled triangle. Two angles are same i.e 45 degrees which means the angle is an isosceles triangle.

so, x = 17 (isosceles triangle)

then use pythagoreas theorem:

[tex]y = \sqrt{x {}^{2} + 17 {}^{2} } [/tex]

and x = 17, so simplify and

[tex]y = \sqrt{17 {}^{2} + 17 {}^{2} } [/tex]

so

[tex]y = 17 \sqrt{2} [/tex]

Answer:

$6

Step-by-step explanation:

Let x be the amount Michael collects from each repeat customer

Since we are given that he charged the new subscribers $3 less than the repeat customers.

So, amount collects from each new customer = x-3

Since he had 40 repeated customers

So, the amount Michael collects from 40 repeat customer = $40x

Since he has 18 new customers

So, amount Michael collects from 18 new customer =$18(x-3)

We are also given that his week, Michael collected $468 for delivering newspapers.

Answer:

$6

40x+ 18 (x-3) = 468
