{y=5x-7
y=-2x+7 Solve the system by graphing.

Answer:

Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).

Step-by-step explanation:

Note: Steps of student are not given. So, the proper steps of the solution are provided below.

Given:

The inequality is

[tex]-5v>55[/tex]

To find:

Where the student made any errors?

Solution:

We have,

[tex]-5v>55[/tex]

On dividing both sides -5 change the sign of equality because -5 is a negative number.

[tex]\dfrac{-5v}{-5}<\dfrac{55}{-5}[/tex]

[tex]v<-11[/tex]

Therefore, the solution of given inequality is [tex]v<-11[/tex].

Answer:

$19

Step-by-step explanation:

Given data

Cost of movie

f(x)=3x+10

Hence the cost of 8 movies is

f(x)=3(8)+10

f(x)=24+10

f(x)=$34

Hence the cost of 8 movies is $34, Kim needs extra

=34-15

=$19

Answer:

5/6 of the movie. 1/2 is the same as 3/6 and 1/3 the same as 2/6. Just add it and boom you got 5/6.

Answer:A perimeter is the sides of a shape added together.

Step-by-step explanation:

Answer:

The perimeter of a rectangle is the total length of all the sides of the rectangle.

Step-by-step explanation:

The perimeter of a rectangle is the total length of all the sides of the rectangle. We can find the perimeter by adding all four sides of a rectangle. Since opposite sides of a rectangle are always equal, we need to find the dimensions of only two sides to find the perimeter of a rectangle.

If you have a 2 inches by 4 inches rectangle, you would have 2 inches + 4 inches + 2 inches + 4 inches = 12 inches

Answer:

3m•sen(60°) es la respuesta

Answer:

Step-by-step explanation:

The best way to do this would be to choose a random number of individuals that have bought a frozen fruit drink to survey. Then this same number of individuals should be surveyed in every single shop in the town. This would allow you to gather data from all of the shops and make sure that the sample is completely representative of the population as long as the individuals are chosen completely at random without introducing any external bias to the choice.

To obtain the value of one unknown quantity linear equation in one variable can be formed. The cost of one mug is given as $21.

A linear equation is a equation that has degree as one.

To find the solution of n unknown quantities n number of equations with n number of variables are required.

Given that,

The cost of 3 calculators = The cost of 7 mugs.

The cost of each calculator is $12 more than each mug.

Suppose, cost of each mug be x.

And, cost of each calculator is x + 12.

As per the question the following equation can be made,

7 ×(x + 12) = 3x

=> 7x - 3x = 84

=> 4x = 84

=> x = 21.

Hence, the cost for one mug is $21.

Answer:

height of b = 280

Step-by-step explanation:

candle b has a height of 280 - 5t, when it comes out of the mold then t=0 so the initial height of b is 280

candle b's height drops by 5 every hour (that's what the -5t part means)

candle a started at 216 and dropped to 192 in 3 hours, so it dropped by 24 in 3 hours so it drops 8 each hour

so candle b starts out taller (280 v. 216) and candle b burns slower (a at 8 per hour and b at 5 per hour), so b will never 'catch up' with a... candle a will be burned out while candle b is still burning

Answer:

24 pink

84 blue

Step-by-step explanation:

2 + 7 =9

2/9 = x/108

108 ÷ 9 = 12

12 × 2 =24

24 pink

7/9 = x/108

108÷9 = 12

12 ×7 =84

Answer:

y=x

Step-by-step explanation:

If we look at this then this is a y=mx+b graph

first lets find the rise/run

so rise = how much it goes up and run = how much it goes right or left

the rise/run of this graph is 1 because each time it goes one up it goes one right.

B= y intercept and the y intercept is 0

So it is y=1x+0 or y=x

answer = y=x
